CLIMATE CHANGE NEWS FOR SEPT. 2012


CC NEWS FOR SEPT.  2012

In June the Renewable Energy Policy Network for the 21st Century (REN21) released its Renewables 2012 Global Status Report.  While hydropower is still the largest renewable energy (RE) electrical power source, others - especially wind and solar - are growing rapidly.  In 2011 nearly 17% of global energy consumption came from RE sources, and investment increased to $257 billion - a six-fold increase over 2004.  2011 also saw a 30% drop in the price of solar PV panels and a 10% drop in the price of offshore wind turbines - making these two RE power sources more competitive with coal and natural gas - without the environmental drawbacks of the fossil fuels, including destructive climate change.  At: http://www.ren21.net/REN21Activities/Publications/GlobalStatusReport/GSR2012/tabid/79218/Default.aspx.  The full 250-page report is a great way to see what is happening in RE around the world and is available online at: www.ren21.net/gsr.

J.Wylie Donald posted an article on July 8 on the ClimateLawyers Blog titled, The NFIP is Renewed and Reformed, and Climate Change is Very Much in the Picture.  The NFIP is the National Flood Insurance Program, which has sometimes paid to rebuild homes severely damaged by floods multiple times.  This year the NFIP was extended for five years and reformed under the Biggert-Waters Flood Insurance Reform Act of 2012.  Provisions of the act include the following:
  • Subsidies for many properties are being phased out.  For example, a "severe repetitive loss property" (i.e., where payments for flood-related damage exceed fair market value of the property) is no longer eligible for a subsidized rate.
  • In setting rates the principles and standards of the American Academy of Actuaries and the Casualty Actuarial Society are to be followed, including "an estimate of the expected value of future costs" .
  • Insurance premiums can now rise up to 20% per year; earlier increases were capped at 10% per year.
  • There are now minimum deductibles for flood claims..
  • A Technical Mapping Advisory Council is established to address flood map revision and maintenance.

On Aug. 20 An Information Statement of the American Meteorological Society on climate change was adopted by the AMS Council and later posted on the web.  It is “intended to provide a trustworthy, objective, and scientifically up-to-date explanation of scientific issues of concern to the public at large.”  “It is based on the peer-reviewed scientific literature and is consistent with the vast weight of current scientific understanding as expressed in assessments and reports from the Intergovernmental Panel on Climate Change, the U.S. National Academy of Sciences, and the U.S. Global Change Research Program.”
“There is unequivocal evidence that Earth’s lower atmosphere, ocean, and land surface are warming; sea level is rising; and snow cover, mountain glaciers, and Arctic sea ice are shrinking. The dominant cause of the warming since the 1950s is human activities.”
“Technological, economic, and policy choices in the near future will determine the extent of future impacts of climate change. Science-based decisions are seldom made in a context of absolute certainty. National and international policy discussions should include consideration of the best ways to both adapt to and mitigate climate change. Mitigation will reduce the amount of future climate change and the risk of impacts that are potentially large and dangerous. At the same time, some continued climate change is inevitable, and policy responses should include adaptation to climate change. Prudence dictates extreme care in accounting for our relationship with the only planet known to be capable of sustaining human life.”  At:
One of the reasons that this statement is remarkable is that meteorologists are often thought of as being ill-informed about climate change.  See the next item.

Forecast the Facts has a funny 2.7 minute video showing what you might see on TV if some weather forecasters tried to inform their audiences about climate change and extreme weather events.  It’s at hoot, titled, Weathergirl goes rogue.  At: 

An Aug. 22 blog post by David Minkow on Climate Access was titled, Latinos’ Values Put Them Ahead of the Curve on Climate.  It quotes Javier Sierra, a media consultant and columnist for the Sierra Club.  “The toxic bombardment that many Latinos are subjected to on a daily basis that results in frequent nose bleeds, asthma and other health ailments is what raises environmental awareness. Latinos see how an unhealthy environment affects the health of their community.” Sierra says.  He adds that it’s easy for Latinos to connect the dots between extreme weather and climate change because their professional activities—from construction to agriculture—tend to keep them in constant touch with a changing environment, and because they tend to keep close relationships with their home countries where climate change is a reality (in part because there aren’t “deniers polluting the public debate”).  Latinos in California play a significant role in defeating Proposition 23 - an effort by the Koch brothers to derail California’s progress toward a clean energy future.  At:

On Aug. 22 the Worldwatch Institute published a report titled, Fossil Fuel and Renewable Energy Subsidies on the Rise.  It pointed out that while global subsidies for renewable energy (RE) sources have been increasing (to $66 billion in 2010), they are still dwarfed by fossil fuel subsidies - estimated at between $775 billion and over $1 trillion in 2012.  RE subsidies are higher on a per kWh basis (1.7 to 15 cents) vs 0.1 to 0.7 cents/kWh for fossil fuels, but the latter have a much larger market share. “The U.S. National Academy of Sciences estimates that fossil fuel subsidies cost the United States $120 billion in pollution and related health care costs every year. But these costs are not reflected in fossil fuel prices.”  Eliminating unnecessary subsidies for fossil fuels and pricing them at their real cost to society would level the playing field for renewable energy sources.  At: 

Ker Than for National Geographic News reported on Aug. 28, in an article titled, Arctic Sea Ice Hits Record Low—Extreme Weather to Come?, that the area of North Polar sea ice  this August reached a new record low - less that the previous record set on Sept. 18, 2007 - and it is expected to shrink more before its minimum for 2012 is reached.  If carbon emissions continue as they have (increasing by about 3% each year),  all of the sea ice will be gone within 30 years  - decades before complete loss was expected to occur - decreasing Earth’s albedo (reflectivity) and increasing the rate of global warming and the frequency of extreme weather events.  At: 

Thalif Deen ran an article on Aug. 28 in IPS News titled, Could Water Strife Lead to ‘Mass Killings’ in the Future?  It grew out of an international water resoources meeting in Stockholm.  He wrote, “As the world faces possible water scarcities in the next two to three decades, the U.S. intelligence community has already portrayed a grim scenario for the foreseeable future: ethnic conflicts, regional tensions, political instability and even mass killings.”  Chris Kojm of the National Intelligence Council estimated that by 2030 nearly half of the world’s population will live in areas of severe water stress.  At: http://www.ipsnews.net/2012/08/could-water-strife-lead-to-mass-killings-in-the-future/

Bill Chameides on Aug. 29 posted an analysis of the words used in the 21-page Romney-Ryan Energy Plan, an article titled, The Romney-Ryan Energy Plan by the Numbers, in National Geographic’s The Great Energy Challenge.  The words ‘oil’ (used 154 times), ‘energy’ (148), ‘gas’ (82) and ‘energy independence’ (21) were some of the most commonly used words.  The words ‘renewable’ (3), ‘conservation’ (2), ‘efficiency’ (1) and ‘biofuels’(1) were hardly used, and ‘climate’ (0) did not appear at all.  At: 

On Sept. 3 John Acheson posted an article on Common Dreams titled, We Are Writing the Epilogue to the World We Knew.  He paints a pretty frightening picture of where society is headed - with the response of our political leaders ranging from denial (Republicans) to inadequate action (Democrats).  I’m afraid he’s largely correct.  At: 

Reuters posted an article on Sept. 7 about RGGI (the Regional Greenhouse Gas Initiative) titled, Fewer than expected bid for cap-and-trade emission permits.  It pointed that the 9 states from ME to MD still in RGGI (NJ’s governor dropped out) sold only 24.6 million carbon dioxide emission allowances - 65% of those offered in the quarterly auction - at a bid price as low as $1.93 per ton of CO2 - too low to have a significant deterrent effect on emissions.  The problem is that the power plants covered by RGGi emitted an annual average on only 126 millions tons of CO2 during the first three years compared to the cap of 188 million tons set before the economic slowdown and the drop in natural gas prices, which encouraged plants to switch to gas from coal.  RGGI was designed to gradually reduce the cap by 10% by 2019.  Clearly the system needs to be redesigned.  At: http://www.reuters.com/article/2012/09/07/us-usa-emissions-market-idUSBRE88612K20120907

A minister in North Carolina, the Rev. Lynn Michie, posted A Climate Change Confession on Sept. 9 in the Ashville  Citizen-Times.  In it she confessed to awakening to some realities during the past year:

1. Our planet is not changing slowly; it is collapsing even more quickly than many scientists predicted.
2. Climate change is not a problem we are leaving for our children and grandchildren to fix. If we do not begin to make major personal and policy changes now, it will be too late. In fact, we’ve already waited too late.
3. The most important thing any president can do right now to help American families is to focus on renewable energy and policies that will help us end our dependence on fossil fuels (not simply ending our dependence on foreign oil).
  1. Climate change is my problem and it is your problem. Scientists will not be able to fix the mess we have all collectively created.
On Sept. 10 Greentechsolar posted an article titled, US Solar Market Spikes With 742 MW in Solar Installations in Q2 2012.  With 477 MW of utility-scale installations in the 2nd Quarter, the U.S. solar market grew by 45% over Q1 2012 and 116% over Q2 2011.  While U.S. residential solar PV grew significantly from Q2 2010 to Q2 2012 - doubling capacity from about 50 to 100 MW in 2 years - utility-scale capacity increased from about 50 to 450 at the same time - a factor of 9!  At: http://www.greentechmedia.com/articles/read/U.S.-Solar-Market-Spikes-with-742-MW-in-Solar-Installations-in-Q2-2012/
The Delaware Coastal Programs Division of the  Department of Natural Resources and Environmental Control (DNREC) has now posted the Vulnerability Assessment report of the Sea Level Rise Advisory Committee, on which I represent the LWV of Delaware.
“This Vulnerability Assessment provides in-depth information about sea level rise and its potential impacts to Delaware in a 2-volume document, an Assessment and a Mapping Appendix. These documents contain background information about sea level rise, vulnerability assessment methods and a comprehensive accounting of the potential extent and impacts that sea level rise could have to 79 resources within the state.”  The extents of sea level rise considered were 0.5, 1.0 and 1.5 meters (about 20, 40 and 60 inches) by 2100.  Some of the resources in Delaware inundated by these increases of sea level are:
  • 1-5% of the residences, approximately 3,500 to 17,000 of them 
  • 2-6% of the length of rail lines, including the Amtrak line through Wilmington linking Washington, DC with New York and Boston
  • 8-11% of the land area of the state 
  • 36-72% of the Port of Wilmington property
  • 84-98% of freshwater tidal wetlands
And these numbers are for a conservative “bathtub” model that does not include high water due to storm surges or wave heights, which are likely to increase in a warming world, as I pointed out in a Minority Statement in Appendix F (pages 190-191).
The complete 2-volume report is available at: http://de.gov/slrva

A Sept. 12 post by Quirin Schiermeier in Nature News is titled, Ice loss shifts Arctic cycles.  It reports that the extent of Arctic sea ice, which is at a record=breaking low,  is influencing both weather patterns and biological systems in unexpected ways.  While computer models have indicated that the polar sea ice may be gone sometime between 2040 and 2100, it looks now as though an ice free summer may come as soon as 2030.  At: http://www.nature.com/news/ice-loss-shifts-arctic-cycles-1.11387

The National Snow and Ice Data Center (NSIDC) reported that the minimum area of Arctic sea ice, reached this year on Sept. 16, was the smallest since satellite measurements first became available in 1979.  The area - 1.32 million square miles - was 18% below the previous record minimum set in 2007 and 49% below the 1979 to 2000 average minimum.  At: http://nsidc.org/arcticseaicenews/

Rate of Arctic Sea Ice Loss Much Greater than Anticipated

Images from CryoSat-2, the first satellite designed specifically to study the thickness of the polar ice caps, show that 900 cubic kilometers of summer sea ice has disappeared from the Arctic Ocean over the past year. The rate of melting is 50 percent higher than most climate projections. The satellite measurements also indicate that the Arctic ice has been thinning dramatically at the same time. In regions north of Canada and Greenland, where a decade ago ice was normally around five to six meters thick during the summer months, the ice has thinned to one to three meters. "Very soon we may experience the iconic moment when, one day in the summer, we look at satellite images and see no sea ice coverage in the Arctic, just open water," said Dr. Seymour Laxon of the Centre for Polar Observation and Modeling at University College London.
It is possible that the sea ice melting was exacerbated by a massive cyclone which passed over the Arctic Ocean during the week of August 6. As reported by NASA climate scientist Claire Parkinson, “It seems that this storm has detached a large chunk of ice from the main sea ice pack. This could lead to a more serious decay of the summertime ice cover than would have been the case otherwise, even perhaps leading to a new Arctic sea ice minimum.” Cyclones are normal this time of year, but according to Parkinson, “Decades ago, a storm of the same magnitude would have been less likely to have as large an impact on the sea ice, because at that time the ice cover was thicker and more expansive.”

Connecticut Officials Say Long Island Sound Must Be Protected Against Climate Change

Connecticut Governor Dannel Malloy and other state officials took part in a panel discussion last week to discuss the impact of climate change on efforts to preserve the Long Island Sound. "The water is definitely getting warmer; there is no doubt about that," Malloy said. "Climate change is already having an impact on the Sound, and it is getting faster." The panelists were optimistic about ongoing sewage plant modernizations and a general trend toward reduced nitrogen levels and better conditions for aquatic life in the Sound. However, many expressed concern over the continued die-off of lobsters in the Sound and uncertainty about how warming waters, sea level rise and fiercer storms will affect life in the state. "We have reason to feel proud, but the lesson is, there is no rest for those seeking to protect this water body and make sure it remains as good as it can be," said Sen. Joe Lieberman (I-CT). "Unless we help the Sound, it will not survive."
In a related story, one of two reactors at the Millstone nuclear power plant in Waterford, Connecticut, was shut down because the water in Long Island Sound was too warm to use as reactor coolant. The reactor’s safety rules state that cooling water can be no hotter than 75 degrees Fahrenheit, but on August 12 the water reached 76.7 degrees Fahrenheit, forcing Dominion Power to shut down the reactor. “Temperatures this summer are the warmest we’ve had since operations began here at Millstone,’’ said Dominion Power spokesman Ken Holt. The 2,100-megawatt Millstone power plant began operations in 1970. “We are evaluating our options for the future,” Holt continued. “We don’t know, is this year an anomaly or is it the continuation of a longer trend?”

Florida Keys Trying to Protect Against Rising Sea Levels

Monroe County, Florida, which encompasses all of the Florida Keys, is set to release its first ever climate action plan this fall. On some Florida islands, just one foot of elevation separates freshwater-dependent pine forests from saltwater mangrove marshes. "As the sea rises and the salt water keeps coming in, the rest of the area eventually is going to look like this marsh," said Chris Bergh, a director at the Nature Conservancy. "It's just a matter of time." David Bender, a botanist in the South Florida Ecological Services Office, said Monroe County could play a huge role protecting threatened species by buying and conserving land adjacent to public areas. The Keys contain many species that are unique to that part of Florida, and the county's cooperation will be needed to help create land corridors for plants and animals to move to higher elevations. The country’s action plan provides a framework for these kinds of climate refuges, stating that the Monroe County Land Authority should place "a high priority on purchasing natural areas for conservation purposes."



Tuvalu Threatened by Climate Change

Rising sea levels of five millimeters a year are slowly eroding Tuvalu, a small island country in the South Pacific. The nine coral atolls of Tuvalu are only two meters (6.5 feet) above sea level at their highest point. James Conway, an American advisor to the Tuvalu government, says, "Tuvalu just got on it very early and has been talking about being an advocate about climate change and sea-level rise since the late 1980s and early 1990s. It's been able to position itself internationally as uniquely threatened, let's say, by sea-level rise, the loss of land, the loss of culture, the loss of sovereignty, the loss of state." Though the New Zealand government accepts 75 Tuvalu islanders immigrants a year, there is no reported agreement by either New Zealand or Australia to accept the total population of 10,500 if the island is destroyed by the effects of climate change.

New Methodology Boosts Evidence for Future Droughts

A study published August 5 in the journal Nature Climate Change provides further support to recent findings (see August 13 issue) that the United States will suffer more severe droughts in the future, and that climate change will play an important role in increasing the frequency and intensity of those droughts. Previous climate models that predicted more severe and widespread droughts have been criticized because they did not fully reflect actual drought patterns when they were applied to historic conditions. This new study uses a statistical method that includes data on sea surface temperatures, and its model accurately portrays historic climate events when applied to past climate conditions. “We can now be more confident that the models are correct, but unfortunately their predictions are dire,” said study author Aiguo Dai, a researcher at the National Center for Atmospheric Research.

Former IPCC Chair Says Planet Likely to Surpass Two Degrees Warming

Professor Sir Bob Watson, currently the chief scientist at the United Kingdom (UK) Department for Food and Rural Affairs and former chair of the Intergovernmental Panel on Climate Change, said that the international target of preventing global average temperatures from rising above two degrees Celsius was no longer viable. He joins a growing number of experts and organizations in this view, including the International Energy Agency. One of the UK government’s most senior science advisors, Dr. Watson cited a lack of progress at international climate meetings as a primary reason for his pessimism. "If we carry on the way we are there is a 50-50 chance that we will get to a three-degree rise. I wouldn't rule out a five-degree world and that would be quite serious for the people of the world, especially the poorest,” he explained. He said that increased political will and continued evolution of energy technology could help avoid the more catastrophic scenarios. Dr. Watson is set to leave his position in the UK government next month.

MIT Study Finds Carbon Tax Could Raise $1.5 Trillion

A new study from the Massachusetts Institute of Technology (MIT) proposes a carbon tax that would raise $1.5 trillion over a 10-year period. Presented in light of looming budget cuts and growing national debt, the study examined the impact of a national tax of $20 per ton of carbon beginning in 2013 and increasing four percent per year. In addition to the direct financial benefits, the study projected that by 2050 the tax would cut oil imports by 10 million barrels per day and reduce carbon dioxide emissions 20 percent below 2006 levels. “Congress will face many difficult tradeoffs in stimulating the economy and job growth while reducing the deficit. But with the carbon tax there are virtually no serious tradeoffs. Our analysis shows the overall economy improves, taxes are lower and pollution emissions are reduced,” explained study co-author John Reilly. The MIT report comes weeks after Rep. Jim McDermott introduced carbon tax legislation in the House (see August 13 issue).

Substantial Methane Reservoirs Trapped under Antarctic Ice

A study published in the journal Nature on August 30 finds that the Antarctic likely holds substantial amounts of the potent greenhouse gas methane trapped under ice sheets. The assessment reveals that ancient organic carbon sedimentary basins are situated under Antarctic ice sheets. The sedimentary basins contain an estimated 21,000 billion tonnes of organic carbon and are expected to be biologically active, meaning that microbes probably have converted the organic carbon into carbon dioxide and methane over thousands of years. According to lead author Jemima Wadham, a professor in glaciology at Bristol University, "This is an immense amount of organic carbon, more than ten times the size of carbon stocks in northern permafrost regions. Our laboratory experiments tell us that these sub-ice environments are also biologically active, meaning that this organic carbon is probably being metabolised to carbon dioxide and methane gas by microbes." The methane – which at high pressure and sub-freezing temperatures becomes methane hydrate – is safely locked beneath the Antarctic ice; however, thinning of the ice could see its release, starting a dangerous positive feedback loop.
For additional information see: BBC, Time


Note: The 21 Gt C that could be released to the atmosphere as Antarctic ice melts is about the amount released 56 million years ago in an event known to geologists as the Paleocene-Eocene Thermal Maximum (PETM), which raised global average temperatures by 5-6 degrees C and caused an oceanic extinction event through ocean acidification by CO2.  See an article called Hothouse Earth in National Geographic at: 


Republican Group Aims to Challenge Party Wisdom on Climate Change

On August 20 an amalgamation of Republican groups came together to form the Young Conservatives for Energy Reform (YCER), propounding, among other solutions, reducing carbon emissions. The grassroots organization plans to host events and rallies where energy experts can discuss issues such as climate change with interested Republicans. The group’s founding is preceded by the launch of the Energy and Enterprise Initiative, a conservative-run think tank which is focused on revising the tax code to disincentivize carbon emissions (see July 23 issue). Brian Smith, chair of YCER’s Midwest chapter, said, "Our position on climate change is that it really shouldn’t be a litmus test for Republicans. We want it to be an issue that Republicans can talk about."

South Florida City Infrastructure Plans to Help Prepare for Rising Sea Levels

Miami Beach is considering a $206 million makeover of its drainage system, due to continued episodes of flooding which raise questions about the existing infrastructure’s ability to withstand pressure from rising sea level. Salt water flooding threatens to contaminate ground water sources and sewage facilities, adding to the cost burden of flood management. The new infrastructure plan, if approved by the Miami Beach Commission, calls for additional pumps, backflow preventers, higher sea walls, and wells to store runoff, to combat short term sea level rise. City public works director Fred Beckmann said of the proposal, “It’s the first time, as far as I know, that any community in South Florida and actually in the entire state of Florida is taking into account sea level rise as they plan their storm water infrastructure.” Recent studies suggest that a three to seven inch rise in sea level is expected in South Florida over the next three decades, which would require investing hundreds of millions of dollars to upgrade drainage systems.

New Research Suggests Dramatic Increases in Food Prices Worldwide Due to Climate Change

A study by Oxfam, released on September 5, concludes that the future impacts of increased temperatures and frequency of extreme weather on food prices have been dramatically understated. The study finds that food prices will likely double by 2030, and with a repeat of the current U.S. drought, the price of maize could increase an additional 140 percent. Additional flooding and drought in Southern Africa could raise the price of corn meal, a staple food for poor families, 120 percent. Large droughts throughout India and vast flooding in Southeast Asia are predicted to increase the world market price of rice by 22 percent. The continuation of climate shocks in sub-Saharan Africa could have dramatic regional effects on grain availability and prices because 95 percent of the grain consumed in the region is grown locally. Tim Gore, climate change policy adviser at Oxfam, states, "Rising temperatures and changing rainfall patterns hold back crop production and cause steady price rises. But extreme weather events – like the current U.S. drought – can wipe out entire harvests and trigger dramatic food price spikes." While the United Kingdom and the United States are predicted to be affected by these changes, the most vulnerable are the world's poorest people, who already are spending up to 75 percent of their income on food.

Carbon Stores Released from Thawing Siberian Ice

According to a new study published August 29 in the journal Nature, large portions of the Arctic Siberian coast that have remained frozen for tens of thousands of years are thawing as atmospheric temperatures rise. Trapped in the receding permafrost of the northern Siberian coastal and Arctic regions are roughly half of the global carbon pools stored in soil. As the ice melts, roughly 40 million tonnes of carbon is released into the atmosphere every year, 10 times the amount previously thought. "Coastal Yedoma (an area of Siberia twice the size of Sweden) is likely more vulnerable towards carbon release than other permafrost bodies as it is not only subject to thermal collapse from above but also to enhanced wave and wind erosion of the Yedoma-dominated coast brought on by sea-level rise and longer ice-free seasons," said study co-author Örjan Gustafsson, professor of biogeochemistry at Stockholm University. Occurring as a result of a changing climate, this release of carbon adds to global greenhouse gas emissions, creating a positive feedback loop and accelerating climate changes.

Climate Change Disrupts Power Plant Operations and Threatens Future Energy Production

Record high temperatures and drought in the United States has caused problems for power plants supplying electricity across the country this summer. The Millstone nuclear plant in Waterford, CT, the Braidwood Nuclear Plant in Braidwood, IL, and one other nuclear plant in the Midwest had to temporarily shut down due to high water temperatures and lack of water for cooling operations. The Illinois Environmental Protection Agency granted exceptions to four coal-fired plants and four nuclear plants, permitting them to release cooling water into local waterways that is seven degrees hotter than federal clean-water permits allow. The severe drought has disrupted coal shipments on the Mississippi River used for electricity generation. Water levels at Lake Mead, the reservoir for the Hoover Dam, are 103 feet below maximum storage capacity, which corresponds to a loss of roughly 500 MW of electricity production this year.

The Colorado River basin, which supplies water to 40 million people and is the source of hydroelectric power for the Hoover Dam, is facing reduced water flow. The Bureau of Reclamation projects that in the next 50 years the lower Colorado River’s flow will decline between nine and ten percent because of climate change, and that water demand will exceed supply by more than a third. Additionally, agricultural demands for water are estimated to rise between three and 10 percent during the same period. University of Arizona law professor Robert Glennon portrayed the water crunch as “a collision.”

Rising Seas Becoming a Threat to New York City

Douglas Hill, an engineer at the Storm Surge Research Group, has criticized New York City for "lacking a sense of urgency" about the threat of rising sea levels to the city's infrastructure and roads. 200,000 residents in New York City live only four feet above high tide. Scientists warn that by mid-century sea levels could rise by two feet, and with higher water, common storms could be as damaging to the city as big storms and hurricanes are today. In light of rising waters, the city is hoping to set aside $2 billion of public and private money to pursue resilience strategies to strengthen the city's ability to deal with and recover from serious flooding. Mayor Bloomberg's administration is implementing features to mitigate future flooding through expanding wetlands to accommodate surging tides, installing green roofs to absorb rainwater, asking people to move boilers out of flood-prone basements, and attempting to reduce greenhouse gas emissions. Yet, even with resilience strategies being put into place, Eddie Bautista, executive director of the New York City Environmental Justice Alliance, warns that there are still many industries on the waterfront, including chemical manufacturing plants, oil-storage sites, and garbage transfer stations, which are prone to future flooding. In addition, current construction projects, such as a new recycling plant on a Brooklyn pier and the Port Authority transit hub at the World Trade Center site, are not necessarily being adapted to future flood risks.

Researchers Consider Human Health Impacts of Climate Change

Researchers in the United States and the United Kingdom (UK) are starting to consider the human health impacts of a changing climate. George Luber, an epidemiologist at the U.S. Centers for Disease Control and Prevention (CDC), said, “[Climate change] is a new topic for public health. This is emerging largely as a result that the scientific evidence around climate change has evolved to the point that public health feels confident engaging the science – that this is a credible threat.” Scientists at the CDC are assessing the local health effects of climate change. Increased atmospheric temperatures lead to more smog in dense urban centers, which can then cause or exacerbate asthma and other respiratory problems. Heat waves, extreme storms and infectious diseases could also increase in frequency and magnitude in a changing climate and thus pose risks for human health. The UK Health Protection Agency concluded that allergy and hay fever seasons could be extended by up to six weeks since flowers will likely bloom earlier with a warmer climate. Scientists at California State University, Bakersfield predict that as temperatures rise and precipitation decreases in arid inland regions, the hardy fungus, which causes valley fever, could flourish because its competitors will die off.

CLIMATE CHANGE NEWS FOR AUG. 2012


CC NEWS FOR AUGUST 2012

Here is some climate news you can use!  ClimateCounts.org has developed a scorecard to compare companies on their commitment to reduce global warming  The higher the score on a scale of 0 to 100, the greater the commitment.  “Climate Counts use a 0-to-100 point scale and 22 criteria to determine if companies have:

  • MEASURED their climate "footprint"
  • REDUCED their impact on global warming
  • SUPPORTED (or suggest intent to block) progressive climate legislation
  • Publicly DISCLOSED their climate actions clearly and comprehensively”

Now you can:

  • Support high-ranked companies when you shop and invest. 
  • Let businesses know that climate does count. Want them to do better? Tell them. Excited about their leadership? Let them know that, too.
  • Tell your friends, colleagues, and family to join you in supporting companies that are taking responsibility for climate change.

Chemical and Engineering News for July 16 had an article by Jeff Johnson titled, Stumbling on the Path to ‘Clean Coal’: Carbon capture and sequestration appears stuck, dashing hopes of cutting CO2 while burning coal.  It points out that the future of coal use for electricity generation in the U.S. may depend on the development of carbon capture and sequestration (CCS) technology, which can capture CO2 from power plants, compress it, and pump it underground for long-term storage (sequestration).  Although the Dept. of Energy (DOE) has provided nearly $7 billion since 2005 to support development of the technology, it has not led to the demonstration of economic viability at scale.  (A typical coal-burning 1000 MW power plant produces about 1000 tons of CO2 per hour!)  It is estimated that CCS would increase the cost of electricity from a coal plant by 75%.  Future funding for CCS development is in doubt - especially in view of falling prices for natural gas and renewable energy. 

On July 19 Bill McKibben posted a compelling article at Rolling Stone Politics titled, Global Warming's Terrible New Math.  In it he writes about three important numbers:
2 degrees C, 565 Gt (gigatons, or billions of metric tons) and 2795 Gt.

The Washington Post for July 23 had an article by Peter Brennan titled, Offshore wind farms will be encouraged in tracts along the East Coast.  It described a coming auction by the federal Bureau of Ocean Energy Management (BOEM) to lease 2,434 square miles of the continental shelf in the Atlantic Ocean for wind farms about 10 miles off the shores of six states from Massachusetts to Virginia.  The article shows a map of the areas to be auctioned.  Full development of the wind resource off the East Coast would permit generation of about 1000 GW of electrical power - the total now used by the United States.  At: http://www.washingtonpost.com/national/health-science/offshore-wind-farms-will-be-encouraged-in-tracts-along-the-east-coast/2012/07/23/gJQAD2Pu4W_story.html

On July 24 the Earth Policy Institute issued an article by Lester Brown titled, World in Serious Trouble on Food Front.  In it Brown pointed out that corn, by far the world’s largest grain crop, started out looking very promising in the spring, with a record number of acres planted, but is now suffering from a severe drought in the major U.S. corn producing states.   On May 21st, 77% of the U.S. corn crop was rated as good to excellent. In the following two months, that dropped to 26% -  one of the lowest ratings on record.  The high prices expected from a poor harvest will affect food prices around the world.  Brown wrote, “Time is running out. The world may be much closer to an unmanageable food shortage – replete with soaring food prices, spreading food unrest, and ultimately political instability – than most people realize.” At:

InterPress Serice (IPS) has an article dated July 24 by Stephen Leahy titled, Scientists Discover New Threats to Corals.  It points out that most corals grow only in shallow water, where there is enough light for them to grow; however those that cannot grow fast enough to keep up with accelerating sea level rise (now 3.3 mm/yr) may die.  Carbon dioxide, which is responsible for most of the sea level rise, also threatens corals by increasing the sea surface temperature and by dissolving in seawater to form carbonic acid, making the water more acidic.  If enough dissolves, as has happened before in Earth’s history, the calcium carbonate that supports the coral dissolves.
The article says, “Overall, some one billion people depend directly or indirectly on reefs for their livelihoods, and more than two billion depend on seafood as a major source of protein.”  At: 
Many fish spend at least part of their life cycle in reefs.

BloombergBusinessweek News for July 24 ran an article by Seth Borenstein titled, NASA: Strange and sudden massive melt in Greenland.  NASA found from satellite observations that the surface of the Greenland ice sheet went from 40% melted to 97% in the course of four days - starting on July 8.  Until then, the largest extent of surface melt seen by satellite was 55%.  At: http://www.businessweek.com/ap/2012-07-24/nasa. 
You can see NASA images at:
It’s hard to tell if this is a one-off event, or will become commonplace.  It could herald a greater acceleration of ice loss.  Loss of all Greenland ice would raise global sea level by 7 m (23 ft).  

On July 25 the Union of Concerned Scientists posted a description of a report titled, Heat in the Heartland: 60 Years of Warming in the Midwest.  It describes studies of temperature and humidity in five major Midwestern urban areas - Chicago, Cincinnati, Detroit, Minneapolis, and St. Louis.  Findings include:
  • Heat waves lasting three days or more have become more common over the last six decades.
  • Hot humid days have increased in frequency, while hot dry days have higher temperatures.
  • Hot air masses have become hotter and more humid during nighttime hours.

Guest blogger Peter Anderson posted an article July 26 in ThinkProgress titled, Why We Need To Pay More Attention To The Role Of Landfills In Global Warming.  In it he pointed out that, while it sounds good to capture methane from landfills to produce electricity, the typical landfill releases about 80% of the methane produced into the atmosphere, where it acts as a very powerful greenhouse gas.  The contribution of landfill gas to global warming has been seriously underestimated.  At: http://thinkprogress.org/climate/2012/07/26/516575/why-we-need-to-pay-more-attention-to-the-role-of-landfills-in-global-warming/
When cellulosic materials - like paper, cardboard, wood or yard waste - are left under anaerobic (oxygen-starved) conditions, such as in a landfill or marsh, methanogenic bacteria convert the carbohydrate molecules to a 1:1 mixture of methane and carbon dioxide.  A good compost box allows air in, so that only CO2 is produced.


Paul Gipe had an article on July 26 in Wind-Works.org titled, Britain Powered by FITs Surpasses US in 2011 Small Wind Capacity, describing the role that Feed-in Tariffs (FITs) have played in the rapid growth of electrical generation from small wind turbines in Britain.  FITs usually have a power distribution company pay a fee (tariff) above the grid price of electricity to small scale (distributed) generators  that use renewable energy sources, recovering their cost from other users.   At: http://www.wind-works.org/SmallTurbines/BritainPoweredbyFITsSurpassesUSin2011SmallWindCapacity.html
This kind of policy has been very successful in promoting the development of  distributed solar PV in Germany.

On July 26 Common Dreams published an article titled, Study: At Least 70% of Arctic Sea Ice Loss 'Man-Made' - Scientists fear the impact of feedback loops as dramatic ice loss begets further melting.  It was prompted by the recent reports that an ice berg twice the size of Manhattan had broken off Greenland and that scientists were astounded to find that nearly all of the surface of the Greenland Ice Sheet had melted for a time - the first time that had been observed.  A new study by climate scientists at the National Centre for Atmospheric Science at the University of Reading, “found that the loss of sea ice around the Arctic is at least 70% due to human-induced climate change -- much higher than previously thought -- and that the number could possibly be as high as 95%.”  “Most concerning to the scientists is the possibility that 'feedback loops' have already begun in which loss of ice begets increased future loss.”  As sea ice is lost less solar energy is reflected and more is absorbed, causing more rapid warming of water and air.  At: 
It has been known for some time that the Arctic is warming twice as fast as the global average - consistent with positive feedback.

The U.S. Energy Information Administration (EIA) announced on July 27 that it expects that electricity generators will lose 27 GW of coal-fired power during the next 5 years - considerably more than the 6.5 GW retired during the past 5.  The 27 GW of retiring capacity is 8.5% of total 2011 coal-fired capacity of 318 GW at the end of 2011.  At: http://www.eia.gov/todayinenergy/detail.cfm?id=7290.
No reason for the increase in retirement rates was given, but my bet is that it’s a combination of the low price of natural gas and the costs involved in expanding coal capacity in the face of EPA requirements for emission reductions for new power plants or major capacity increases for existing plants.

On July 31 Lester Brown of the Earth Policy Institute released a report titled, We Can Reforest the Earth.  In it he  points out that the shrinkage of forests - primarily in the tropics exceeds reforestation, resulting in an net addition to the atmosphere of about 1.5 billions tons of carbon - about a quarter of what we release from the burning of fossil fuels.  He points out the importance of reforestation, especially in the tropics, where trees grow much more rapidly.  One hectare (about 2.5 acres) of forest plantation produces 4 cubic meters of wood per year in eastern Canada, 10 cubic meters in the southeastern United States, and 40 cubic meters in Brazil.

On Aug.3 James Hansen published an Opinion piece in the Washington Post titled, Climate change is here — and worse than we thought.  In it he described a study, recently published by the National Academy of Sciences, making clear that while the global average temperature has been slowly rising due to a warming climate (1.5 degrees F in the past century - mostly in the last 30 years), extremes are becoming much more frequent and more intense.  Droughts and floods that were once very rare are now becoming almost commonplace.  At: http://www.washingtonpost.com/opinions/climate-change-is-here--and-worse-than-we-thought/2012/08/03/6ae604c2-dd90-11e1-8e43-4a3c4375504a_story.html

Bipartisan Support for Carbon Tax; Disagreement over Proposed Tax Swaps

Organizations, activists and policy experts from across the political spectrum show increasing support for inclusion of a carbon tax during the expected tax reform package in the next session of Congress. There is disagreement, however, on whether the tax should be used to raise revenue or cut other taxes. Conservatives who support a carbon tax, including economist Kevin Hassett of the American Enterprise Institute, former Rep. Bob Inglis (R-SC), and former President Reagan's Secretary of State George Shultz, favor a revenue-neutral system that will cut corporate or income taxes. While some organizations argue for "consumer-centric" cuts to payroll and dividend taxes as a method to offset higher consumer prices caused by the carbon tax, other organizations refuse to support a revenue-neutral carbon tax. Instead, these organizations favor using the carbon tax to reduce the deficit. In related news, aides of House Speaker John Boehner (R-OH) and Senate Minority Leader Mitch McConnell (R-KY) said neither official would support a carbon tax.

Conservatives Launch Climate Change Initiative

On July 10 George Mason University announced the launch of the Energy and Enterprise Initiative (E&EI) which promotes conservative solutions to America's energy and climate problems. Former Rep. Bob Inglis (R-SC), who called his belief in climate change his "most enduring heresy" in an interview with Grist writer David Roberts, will lead E&EI. “Conservatives have the answer to our energy and climate challenge," said Inglis. "It’s about correcting market distortions and setting the economics right. We need to stop retreating in denial and start stepping forward in the competition of ideas.” E&EI supports pairing a carbon tax with an income tax reduction as a revenue-neutral way to tackle climate change. The initiative has support from Gregory Mankiw, economic advisor to the Romney campaign; Douglas Holtz-Eakin, former head of Bush's Council on Economic Advisers; Arthur Laffer, conservative economist and former senior adviser to President Reagan; and George Shultz, former Secretary of State to President Reagan.



Climate Change Forces Businesses to Adapt

A recent study by Oxfam and several companies found that businesses worldwide incurred upwards of $60 billion in weather-related insurance losses in 2011. As stated by Dr. Juan José Daboub, CEO of the Global Adaptation Institute, “People have started to realize there are water shortages and droughts. . . Not only are their businesses in jeopardy, but there is a business opportunity to provide solutions.” Entergy Corp., a Louisiana electric utility, spent nearly $2 billion rebuilding following Hurricanes Katrina and Rita. In the aftermath, the utility relocated its offices and mobilized the local business community towards adaptation. Jeff Williams, director of climate consulting for Entergy, said, “All too often, we use the uncertainty of climate change to ask ourselves, 'Is it happening or isn't it?' I think the uncertainty isn't that. It's how big the impact is going to be."

Greenland Glacier Calves Ice Island

On July 16 researchers at the University of Delaware and the Canadian Ice Service reported that an ice island had broken off from Greenland’s Petermann glacier. Andres Muenchow, University of Delaware associate professor of physical ocean science and engineering, said, “The Greenland ice sheet as a whole is shrinking, melting and reducing in size as the result of globally changing air and ocean temperatures and associated changes in circulation patterns in both the ocean and atmosphere.” The Petermann glacier shed a large ice island in 2010, and Monday’s 46-square mile ice island is twice the size of Manhattan. Continued Muenchow, “The fact that it follows so closely to the 2010 event brings the glacier’s terminus to a location where it has not been for at least 150 years.”

In related news, a record amount of Arctic sea ice melted during the month of June. The National Oceanic and Atmospheric Administration records show that the Arctic lost 1.1 million square miles of ice in June, the most on record. While Arctic sea ice melting is normal during the Northern hemisphere summer, the magnitude of the loss means that the Arctic sea ice extent is 9.8 percent below average, the second lowest on record since 1979.



China’s Carbon Emissions Now Similar to Europe’s on a Per Capita Basis

On July 18 PBL Netherlands Environmental Assessment Agency and the European Commission's Joint Research Centre published a study which found that the average Chinese person’s carbon emissions are on par with an average European’s. The study reports that China’s emissions increased 9 percent in 2011 to 7.2 tonnes per person, only slightly less than the European average of 7.5 tonnes per person. Chinese per capita emissions are still less than half of the average American at 17.3 tonnes per person. When import and export of goods and international travel are accounted for, the developed world emits more carbon per capita than China, since it is estimated that one-fifth of goods produced in China are for export.

Annual Global Carbon Emissions Increase in 2011

Global carbon dioxide (CO2) emissions rose to 34 billion tons in 2011, up three percent from the previous year, according to a report from the European Union’s Joint Research Center. Global emissions must be less than 1,500 trillion tons of CO2 between 2000 and 2050, in order to limit global temperature increase to the United Nation’s goal of 2 degrees Celsius by 2050. "If the current global trend of increasing CO2 emissions continues, cumulative emissions will surpass this limit within the next two decades," said the report. As reported last week, China’s emissions increased nine percent in 2011 (see July 23 Issue), while the United States cut its emissions by two percent.  [Emphasis added]

Environmental Group Targets Republicans who Question Climate Change

The League of Conservation Voters (LCV) launched a $1.5 million campaign July 24 aimed at preventing the re-election of five House Republicans who question the connection between climate change and human activity. The LCV, an environmental group that tracks politicians’ environmental voting records, is targeting to defeat Rep. Ann Marie Buerkle (R-NY), Rep. Dan Benishek (R-MI) and three other yet-unnamed House Republicans because of their stance on global warming. Both Rep. Buerkle and Rep. Benishek have questioned whether anthropogenic emissions have contributed to climate change in the past. “There’s still a debate about how to address these issues, but Americans expect their politicians to be informed and to accept basic science,” said Navin Nayak, LCV Senior Vice President for Campaigns. “Independents are with us. All of these members are in places where they have to win a majority of independent voters to win reelection.”

Pulling Carbon Directly from the Air May Become Economically Feasible

Researchers from Georgia Institute of Technology have developed a technique for extracting carbon dioxide (CO2) directly from the air using newly-developed adsorbent materials. In a series of papers published this month, the researchers detailed how a CO2 removal unit about the size of a shipping container could extract 1,000 tons of CO2 per year at a cost of $100 per ton. This technique could initially be used to collect carbon for use in biofuels production or advanced oil recovery, but it could eventually be applied on a wider scale to help lower CO2 concentrations in the atmosphere. Georgia Tech professor Christopher Jones is collaborating with a startup company to establish a pilot plant to demonstrate the direct air capture technique.
In a related story, a new paper from Columbia University’s Earth Institute argues that direct air capture techniques may become important tools to combat global warming. The authors say methods of capturing carbon from stationary sources, such as factories and power plants, do not address emissions from airplanes, vehicles, and other small emissions sources – which account for almost half of the world’s greenhouse gas emissions. Therefore, direct air capture techniques could be the best way to stabilize atmospheric carbon levels in the future.

American Opinions about Climate Change Unchanged from 2011

The most recent “Global Warming’s Six Americas” study concludes that opinions are relatively unchanged since May 2011. The ongoing study by researchers at Yale University and George Mason University, seeks to understand American opinions toward climate change. The researchers separate respondents in to six groups—alarmed, concerned, cautious, disengaged, doubtful, and dismissive—representing the spectrum of climate change views. The July 18th update which includes polling results from November 2011 and March 2012, finds that 13 percent of Americans are alarmed, 26 percent are concerned, 29 percent are cautious, 6 percent are disengaged, 15 percent are doubtful and 10 percent are dismissive. Overall, the attitudes are mostly unchanged, but the number of “cautious” increased from 24 percent in May 2011 and the number of “disengaged” decreased from 10 percent. The majority of respondents believe that climate change is affecting the weather in the United States, including 93 percent of the “alarmed” group and 92 percent of the “concerned” group. More than half of the study participants (60 percent) said they would vote for a candidate who supports a revenue-neutral carbon tax in which the returns from a carbon tax are used to offset the federal income tax. The March 2012 survey included 1008 adults, the margin of error is plus or minus three percent.

Climate Change Would Displace Millions

In a recent interview on National Public Radio, researchers discussed the danger of forced displacement due to lasting effects of climate change. Celia McMichael, research fellow at Australia’s La Trobe University, and Jon Barnett, political geographer at Australia’s University of Melbourne, discussed the need for global policy to counteract climate change-induced forced displacement, planned resettlement, and urban migration. Celia McMichael said, “Any climate change–related migration is going to be along the lines of existing migratory patterns, and they are typically within developing regions. So I think at a policy level the point is to look at migration not as a problem that needs to be managed, including by undeveloped countries, but [as] part of an adaptation portfolio, with this issue in mind that migration can have adverse outcomes, including health outcomes.”
In related news, a study published on June 12 in Global Change Biology found that climate change, particularly rising sea levels, would turn millions of Southeast Asian and Pacific islanders into climate change refugees. Lead author Florian Wetzel said, "Sea level rise will lead to the permanent inundation and erosion of coastal areas,” displacing anywhere from 8 to 52 million people.




Drought Emphasizes India’s Vulnerability to Climate Change

Because of a late-arriving monsoon, India is suffering its second drought in four years. Rainfall across the nation is down an average of 20 percent, but in India’s northern agricultural regions the drought is much worse. "We know that the rainfall in August will not be able to fill the gap, and the problem is getting really serious," said Harjeet Singh, an international climate justice coordinator at ActionAid. "The impacts on the ground in terms of food security are yet to be seen. Unless the government prepares, it could be really tragic." Low precipitation levels are also reducing India’s ability to generate hydroelectric power, which contributed to last week’s blackouts that left over 600 million people without power. "With climate change, wetter regions may get wetter; dry ones may become drier," said Andrew Robertson, a scientist at the International Research Institute for Climate and Society at Columbia University. "With the monsoon season, some rainfall may be distributed less evenly. We may see larger extremes, more intensity. That's what the models suggest.”

Climate Change Altering Way of Life in Alaskan Villages

Melting permafrost, receding Arctic ice and more severe storms are threatening the way of life of many Alaskan villages. Point Hope, a coastal village north of the Arctic Circle, is struggling to cope with these changes. “So much of our culture is being washed away in the ocean,” said Point Hope Mayor Steve Oomittuk. “We live this cycle of life, which we know because it’s been passed from generation to generation. We see that cycle breaking.” Native Inuits, like Oomittuk, have stored whale meat in ice cellars under their houses for thousands of years, but melting permafrost is causing these cellars to disintegrate. Villagers rely on hunting and fishing for a substantial portion of their diet, but receding sea ice is making it much more difficult to hunt seals than in years past. The biggest threat, however, comes from soil erosion as the Alaskan soil heats up and begins to thaw. The town of Kotzebue constructed a $34 million sea wall, primarily funded by the federal government, to protect its beach from rising seas and erosion, but many villages have given up and are trying to relocate to higher ground. The U.S. Department of the Interior is launching an effort to evaluate the environmental, social and economic impact of climate change on the Arctic infrastructure.

Shellfish Vulnerable to Ocean Acidification

A study published in the journal Global Change Biology, finds that ocean acidification is impacting the ability of crustaceans to produce shells, which could leave them exposed to predators. The study analyzed clams, sea snails, lamp shells and sea urchins at 12 sites from the North Pole to the South Pole. “The results suggest that increased acidity is affecting the size and weight of shells and skeletons, and the trend is widespread across marine species,” said study co-authors from the British Antarctic Survey in a written statement. The ocean is a major sink of atmospheric carbon dioxide (CO2) (see August 6 issue). Dissolved CO2 forms carbonic acid which inhibits the formation of calcium carbonate-based shells and skeletons, a phenomenon especially pronounced in cold water. "Where it gets colder and the calcium carbonate is harder to get out of the seawater the animals have thinner skeletons ... we think that the polar regions, and especially Antarctica, are likely to be the first places where animals reach these critical problems for making skeletons," said Professor Lloyd Peck of the British Antarctic Survey. Historically, animals have adapted by forming lighter skeletons, and according to study co-author Dr. Sue-Ann Watson of James Cook University, “Given enough time and a slow enough rate of change, evolution may again help these animals survive in our acidifying oceans.”

Severe Drought May Become the New Normal in American West

A study published on July 29 in Nature Geoscience has found that, in the coming century, the climate in western North America will be similar to conditions during the long-term drought that hit the area from 2000 to 2004. The study warns that conditions will be closer to the "wet end" of a drier hydroclimate during the latter half of the 21st century. "Climatic extremes such as this will cause more large-scale droughts and forest mortality, and the ability of vegetation to sequester carbon is going to decline," said co-author Beverly Law, a professor of global change biology and terrestrial systems science at Oregon State University. The 2000 to 2004 drought, the worst in 800 years, severely reduced carbon absorption in western forests, and the area’s ability to sequester carbon will decrease even further in the future, according to the study.
