estimated, according to a new study. The decline of albedo, or reflectivity, from the Arctic Ocean equals roughly 25 percent of the warming caused by rising carbon dioxide levels, according to scientists at the University of California, San Diego. The impact of this "albedo feedback," in which the highly reflective white surface of sea ice is replaced by heat-absorbing open ocean, is considerably stronger than climate models had predicted, according to the UCSD research, published in the Proceedings of the National Academy of Sciences. Researchers had thought increasing Arctic cloud cover might slow the albedo feedback, but this study indicates that is not happening.

Five Questions for Elizabeth Kolbert
On Facing Up to the Sixth Extinction

Elizabeth Kolbert's new book, The Sixth Extinction, focuses on one of the most troubling realities of our age: We are living in a period when, for only the sixth time in earth’s history, the diversity of species is contracting suddenly and rapidly — but now, we humans are the cause. For her reporting, Kolbert, an e360 contributor and New Yorker staff writer, traveled from the Peruvian Andes to Australia's Great Barrier Reef, probing the fate of a dozen species. Yale Environment 360 asked Kolbert five questions about the book and what she discovered in researching it.

14 Feb 2014: Climate Benefits of Natural Gas
Are Questioned in A Major New Report

The U.S. Environmental Protection Agency has been underestimating methane leaks from natural gas production and use by 25 to 75 percent, according to a comprehensive assessment of more than 200 studies. When the methane leaks are accounted for, natural gas contributes to climate change more than industry and the EPA have claimed, concludes the report by a team of U.S. scientists. In some cases, natural gas contributes to warming more than other fossil fuel sources. For instance, fueling trucks and buses with natural gas instead of diesel likely increases emissions, because diesel engines are relatively efficient, according to the researchers. Natural gas has been touted as an important "bridge fuel" because it emits less CO2 during combustion than oil and coal. Recently, though, studies have indicated that leaks of methane, a more potent greenhouse gas than CO2, during natural gas production, transportation, and consumption may offset its climate benefits. The new report, published in Science, synthesized the results of 20 years' worth of methane leakage studies.

12 Feb 2014: Despite Costs, Most Americans
Want Action on Climate Change, Report Finds

A large majority of Americans — 83 percent — say the U.S. should make an effort to reduce global warming, even if those efforts have economic costs, according to a new report from the Yale Project on Climate Change Communication. As many as 56 percent of Americans would be willing to pay an extra $100 each year if their power company would generate 20 percent of its electricity from renewable sources. Corporations and industry should be doing more to stave off climate change, according to 65 percent of people interviewed in a national survey, and 61 percent believe individual citizens should also be taking a more active role. Many of the survey's findings are similar across Democratic and Republican party lines. Tax rebates for energy-efficient vehicles and solar panels are popular among people aligned with both parties, for example, as well as funding renewable energy research and regulating carbon dioxide as a pollutant. And people from both parties are generally supportive of ending all fossil fuel subsidies, although Democrats (67 percent) are more supportive of that policy than Republicans (52 percent).

High-resolution data on biodiversity, endemism, and vegetation density allowed the researchers, led by Patrick Jantz of the Woods Hole Research Center, to determine which corridors are most important for maintaining biodiversity under changing climate conditions. The maps also highlight which corridors are most important for sequestering carbon and averting carbon emissions associated with deforestation. Researchers hope the findings will help guide wildlife protection plans and serve as a framework prioritizing the conservation of habitat corridors.

05 Feb 2014: Vast Forests and Frequent
Fires Were Key Causes of Ancient Warming

The release of volatile organic compounds from forests and smoke from wildfires had a far greater impact on global warming 3 million years ago than ancient atmospheric levels of carbon dioxide, a new study finds. During the mid-Pliocene epoch, forests covered a much larger percentage of the planet, releasing large amounts of volatile organic compounds, according to Nadine Unger of the Yale School of Forestry & Environmental Studies. Those compounds are precursors to ozone and organic aerosols, which are both potent greenhouse gases. The dark foliage of the planet's abundant forests also absorbed large amounts of solar energy, another reason why the Pliocene was a relatively warm era even though atmospheric levels of CO2 were not exceptionally high. The research — based on earth-system modeling that used a supercomputer capable of processing 52 trillion calculations per second — provides evidence that dynamic atmospheric chemistry played an important role in past warm climates, underscoring the complexity of climate change, the authors write in Geophysical Research Letters.

A high pressure system off the state's western coast sent warm air and rain through Alaska instead of down into California, which is in the midst of a record drought. The warmest January temperature ever observed in Alaska was tied on January 27, when the thermometer hit 62 F (16.7 C) at Port Alsworth, in southern Alaska. Combined with rainstorms, the heatwave set off a host of spring-like effects, including avalanches and swollen rivers, which carried major sediment loads into the Gulf of Alaska. Inland, Arctic lakes are also seeing consequences of Alaska's long-term warming trend. A new study found that lakes in the region froze almost six days later and broke up about 18 days earlier in the winter of 2011 compared to the winter of 1950.

The unprecedented speed appears to be the fastest ever recorded for any glacier or ice stream in Greenland or Antarctica, the researchers report in the journal The Cryosphere. Scientists estimate the glacier added about 1 millimeter to global sea levels from 2000 to 2010; its faster flow into the ocean means Jakobshavn will add even more water over the current decade. Widely thought to be the source of the iceberg that sunk the Titanic in 1912, the researchers say Jakobshavn is flowing at record speeds because its front edge, called the calving front, now overlies a particularly deep spot on the ocean floor. "As the glacier’s calving front retreats into deeper regions, it loses ... the ice in front that is holding back the flow, causing it to speed up," the lead researcher explained.

31 Jan 2014: U.S. State Department Report
Boosts Prospects of Keystone XL Pipeline

In a long-awaited report, the U.S. State Department has concluded that the carbon-heavy oil from Alberta's tar sands will be extracted whether or not the Keystone XL pipeline is built, improving the prospects that the highly controversial project will be built. In an environmental impact statement that was six years in the making, the State Department concludes that the process of extracting and burning tar sands oil creates 17 percent more greenhouse gases than traditional oil, but that the heavily polluting oil will be brought to market with or without the pipeline. "It's unlikely for one pipeline to change the overall development of the oil sands," said a State Department official. If completed, the pipeline would carry 830,000 barrels of oil a day from Alberta to refineries on the coast of the Gulf of Mexico. President Obama will make the final decision on the Keystone XL pipeline and he vowed last year that he would approve the pipeline only if it would not "significantly exacerbate" the problem of carbon emissions. Environmental activists such as Bill McKibben of 350.org have said it would be "game over" for the climate if Keystone XL is built.

The animation begins in 1950, but the intensity of the yellow, orange, and red colors shows how much temperatures have increased compared to baseline temperature data collected from 1880 to the present. NASA said that nine of the planet's 10 warmest years have occurred since 2000, and worldwide surface temperatures continued to rise in 2013, according to satellite and meteorological data. Since 1880, when atmospheric concentrations of CO2 were 285 parts per million (ppm), the average global temperature has risen 1.4 degrees F; atmospheric CO2 concentrations crossed a milestone of 400 ppm last year. "Long-term trends in surface temperatures are unusual and 2013 adds to the evidence for ongoing climate change," NASA scientist Gavin Schmidt said.

Canada, will likely be too warm by the middle of this century. Even under conservative climate change scenarios, only 11 of the 19 sites would remain climatically stable enough to reliably host the games, the study found. Olympic organizing committees consistently cite poor weather as a major challenge for the winter games, and it's likely to get more challenging: The average February daytime temperature of winter games locations has steadily increased — from 0.4 degrees C at games held in the 1920s to 1950s, to 3.1 degrees C in the 1960s to 1990s, to 7.8 degrees C so far in the 21st century. These sites will likely warm by an additional 2.7 to 4.4 degrees C by the end of the century, according to the report.

In addition, California's vital agricultural areas in the Sacramento and San Joaquin valleys, which lie west of the Sierra Nevada, are a parched brown. By contrast, a satellite image taken in January 2013 shows significant snowpack in the mountains and a swath of green in the Sacramento and San Joaquin Valleys. Half of California's yearly precipitation falls between December and February, so January's record dry conditions threaten water supplies for the entire year.

20 Jan 2014: Soil Microbes Can Alter DNA
In Response to Climate Change, Study Says

A 10-year study of soil ecosystems has determined that microbes alter their genetic code in response to a warming climate so they can process excess carbon being absorbed by plants from the atmosphere, a team of U.S. researchers reports in the journal Applied and Environmental Microbiology. A 2-degree Celsius temperature increase spurred microbes in soil ecosystems to, over many generations, tweak their DNA, amping up their respiratory systems and converting extra organic carbon in the soil to CO2. The soil contained extra carbon because the 2-degree temperature increase made plants grow faster and higher; when those plants began to die, the carbon in their leaves, stems, and roots was added to the soil and taken up by the microbial community. Understanding the "black box" of carbon's fate in soil ecosystems holds important clues for better forecasting an ecosystem's response to climate change, says Georgia Institute of Technology researcher Kostas Konstantinidis, an author of the study. "One reason that models of climate change have such big room for variation is because we don’t understand the microbial activities that control carbon in the soil," he said.

A major Antarctic ice mass, the Pine Island Glacier, is melting irreversibly and could add as much as a centimeter to global sea level rise over the next 20 years alone, according to new research published in Nature Climate Change. Calculations show that the Pine Island Glacier's "grounding line" — where land-based ice meets a floating ice shelf that is an extension of the

glacier — has retreated roughly 10 kilometers in the past decade. Scientists say that the grounding line is in the process of a 40-kilometer retreat that could push it beyond an important tipping point. Pine Island Glacier is a major contributor to global sea level rise and has been losing massive amounts of ice for decades, accounting for 20 percent of the West Antarctic Ice Sheet's total ice loss. An international research team says that the Pine Island Glacier has been losing 20 billion tons of ice annually for the past two decades and could lose 100 billion tons annually over the next 20 years. The glacier "has started a phase of self-sustained retreat and will irreversibly continue its decline," says Gael Durand, a glaciologist with France's Grenoble Alps University.

10 Jan 2014: Natural Gas Has Sharply
Reduced Emissions from Power Plants

The dramatic increase in using natural gas to produce electricity in the United States has led to an equally dramatic decline in the amount of pollutants and carbon dioxide emitted from the nation’s power plants, according to a new study. The study, conducted by researchers at the National Oceanic and Atmospheric Administration, showed that the switch from coal-fired to natural gas-fired power plants has reduced CO2 emissions by 23 percent and emissions of nitrogen oxides and sulfur dioxide by 40 and 44 percent, respectively. Examining power plant emissions from 1997 to 2012, the scientists found that new combined-cycle natural gas-fired power plants — which use two heat engines in tandem to convert a higher fraction of heat into electrical energy — emit less than half the amount of CO2 as coal-fired power plants. The study, to be published in the journal Earth’s Future, said that the fraction of electricity produced in the U.S. from coal fell from 83 percent in 1997 to 59 percent in 2012. Meanwhile, the fraction of electricity generated by combined-cycle natural gas plants rose from zero to 34 percent.

Emperor Penguins Alter Breeding Tactics

Confronted with the loss of sea ice in some parts of Antarctica, four colonies of emperor penguins have come up with an innovative breeding strategy to adapt to their changing environment. Using satellite images,

an international team of scientists tracked the four colonies from 2008 to 2012. In the first three years, the emperor penguins hatched and incubated eggs in their customary fashion — atop the sea ice that freezes during the Antarctic winter and spring. But in 2011 and 2012, sea ice did not form until a month after the breeding season began. As a result, the emperor penguins, which are the largest penguin species on earth, did something never before witnessed by scientists: They climbed the nearly sheer walls of large, floating ice shelves — huge structures, often hundreds of square miles in extent, that flow from land-based glaciers into the sea. In the region of the four colonies, the ice shelf walls reach as high as 100 feet. The scientists say the altered breeding behavior could demonstrate how ice-dependent emperor penguins may adapt to a warming world.

08 Jan 2014: China Approves Major
Increase in Huge Coal Mining Projects

In 2013, the Chinese government approved 15 large coal mining projects that will produce more than 100 million new tons of coal a year. The expansion will lead to a 2 to 3 percent growth in coal production over the next several years, even as the country announced moves to reduce the severe air pollution choking major cities such as Beijing. Chinese officials will increase coal production while reducing pollution in population centers by closing outdated coal plants and creating huge “coal bases” that will mine and burn coal in remote regions of northwestern China, such as Inner Mongolia. Those bases, which will cost $8.9 billion to build, will generate electricity that will be transferred over an improved electricity grid to cities in China’s central and eastern regions. Deng Ping, an environmental campaigner with Greenpeace, said the scale of the new coal bases is unprecedented for China, adding, “Despite the climate change pressure, water resource scarcity, and other environmental problems, the coal industry is still expanding fast in northwest China.”

Studying traps that have been suspended for 13 years in the Fram Strait, scientists from the Alfred Wegener Institute found that small species of crustaceans common to the Atlantic are increasingly moving into Arctic waters. The researchers found fertile females as well as individuals at all stages of development, showing that the Atlantic species is reproducing in the frigid waters. The one-centimeter amphipods are smaller than respective Arctic species, meaning that the spread of the Atlantic crustaceans northward could reduce the volume of food available to Arctic predators.

26 Dec 2013: Solar Activity Not a Major
Factor in Climate Change, Study Finds

Solar activity has had minimal impact on climate over the past millennium, new research from the United Kingdom indicates. The findings counter the long-held view that periodic fluctuations in the sun's energy output have led to lengthy periods of warm or cold weather in the past. Looking at climate records from the Northern Hemisphere over the past 1,000 years, the scientists found that greenhouse gases have been the primary drivers of climate change since about 1900. Volcanic activity, which adds particles to the atmosphere that block sunlight, dominated climate patterns until roughly 1800, the study found. "Until now, the influence of the sun on past climate has been poorly understood," said Andrew Schurer of the University of Edinburgh and lead author of the study, which was published in Nature Geoscience. "We hope that our new discoveries will help improve our understanding of how temperatures have changed over the past few centuries, and improve predictions for how they might develop in future."

19 Dec 2013: Los Angeles Becomes First
Major U.S. City to Adopt Cool Roof Rule

The Los Angeles City Council has voted unanimously to require "cool roofs" for all new and refurbished homes, becoming the first major U.S. city to do so. "Cool roofs" incorporate light- and heat-reflecting building materials, which can lower the surface temperature of the roof by up to 50 degrees F on a hot day, according to Climate Resolve, the local organization that pushed for the ordinance. Such roofs do not necessarily need to be white, the Global Cool Cities Alliance says; they can also be shades of gray, or even red. Research suggests that by mid-century temperatures in Los Angeles will increase by 3.7 to 5.4 degrees F, with the number of days above 95 degrees F tripling in the city's downtown. "The changes our region will face are significant, and we will have to adapt," said UCLA scientist Alex Hall, who led the research.

17 Dec 2013: Australian Coal Projects
Threatened by Drop in Demand From China

Major Australian coal projects risk losing value due to falling demand from China, where leaders are increasingly concerned about growing public anger over severe air pollution, a new analysis from Oxford University has found. Future coal mining projects are vulnerable to being "stranded" by a range of policy changes from the Chinese government, including environmental regulation, carbon pricing, investment in renewable energy, and energy efficiency, the report said. One expert told The Guardian that global investors are already questioning the prudence of financing new fossil fuel projects. Backers of a handful of upcoming Australian coal projects "should seek clarity" on the associated costs, the Oxford analysis warns. It also cautions that Australian state governments could suffer if projects are mothballed or abandoned. Of particular concern are two mega-mines supported by Australia's Prime Minister Tony Abbott slated for development in Queensland. Once running at full capacity, the two projects combined would produce enough coal to emit more than 70 millions tons of CO2 a year.

04 Dec 2013: New Paper Offers Sweeping
Plan to Decarbonize the Global Economy

Eighteen prominent international climate scientists and economists have authored a paper that seeks to answer the most vexing environmental question facing the planet: How to reverse soaring carbon dioxide emissions and prevent the world from experiencing destabilizing climate change. Their answer, presented in the journal PLOS One, boils down to this: Offer global leaders a detailed blueprint for decarbonization that involves setting a steadily rising price on carbon, the large-scale deployment of nuclear power and renewable energy, increased research into low-carbon energy technologies, and a reform of forestry and agricultural policies that leads to massive sequestration of CO2 — all while not spending more than 1 percent of global gross economic output. “In terms of economics, comparing a path to decarbonization versus a path of wrecking the planet are not even close,” economist Jeffrey Sachs, a co-author of the paper and director of Columbia University’s Earth Institute, said at a press briefing. “We haven’t shown the path of decarbonzation clearly enough (and) what the real choices are.”

27 Nov 2013: China Set to Open
World's Second Largest Carbon Market

China is in the midst of launching seven carbon markets, the largest of which will open next month in Guangdong, the country's most populous province. The carbon markets are a key element of China's plan to cut carbon emissions by up to 45 percent per unit of GDP by 2020. The Guangdong carbon permitting scheme will cap 2013 emissions at 350 tons for 202 companies in the heavily industrialized province. Twenty-nine million permits will be auctioned in the market this year and next, which will be the world's second largest carbon market after the European Union's, dwarfing carbon markets in Australia and California. In 2015 the number of permits auctioned will more than triple, officials said. Shanghai's carbon market launched yesterday and a similar market, about a quarter of the size of Guangdong's, is set to open in Beijing tomorrow. China's seven carbon markets together will regulate roughly 700 to 800 million tons of CO2 annually, roughly equal to the annual emissions of Germany.

25 Nov 2013: Despite Discord, Climate Talks
in Warsaw End With Last-Minute Deals

After more than 36 hours of continuous negotiations, delegates at the U.N. climate talks in Warsaw agreed to two last-minute deals that kept alive hopes for staving off climate change. At talks that ended Saturday, delegates agreed to a proposed system for pledging cuts in greenhouse gas emissions. They also gave support to a new treaty mechanism for tackling the human cost of the effects of global warming, including floods, rising seas, and stronger storms, The New York Times reports. Parties also agreed that countries will have until early 2015 to lay out their plans for cutting greenhouse gas emissions. Those plans are to be published in advance of a major U.N. climate meeting in Paris, set for late 2015, at which international leaders hope to reach an agreement to curb global emissions starting in 2020. Discord and acrimony characterized the talks, during which a vocal negotiating bloc emerged among developing countries, including India, China, and Saudi Arabia. This bloc forced the watering down of key aspects of the deal, according to the Guardian.

21 Nov 2013: U.K. Government Pledges
To Stop Backing Foreign Coal Power Plants

The United Kingdom has joined the U.S. in pledging to stop using government funds to finance coal-fired power plants in other countries. "The two governments are going to work together to secure the support of other countries ... and the multilateral development banks to adopt similar policies," Britain's energy secretary told journalists gathered in Warsaw at the U.N. climate talks. The U.S. made the same pledge last month in an attempt to slow CO2 emissions from the world's coal-fired power plants. The International Energy Agency reports that coal accounted for 44 percent of global carbon emissions in 2011, and the fossil fuel remains the world's largest source of electricity and heat. While many diplomats applaud the U.K.'s move, U.N. Secretary General Ban Ki-moon and environmental groups are pushing for even stronger action, including more spending on renewable energy. "The rapid development of low-carbon infrastructure needs large injections of public capital," Ki-moon said.
