Arctic sea ice is 'toast' as old record shattered
(09/19/2012) Some twenty days after breaking the record for the lowest sea ice extent, the Arctic sea ice has hit a new rock bottom and finally begun its seasonal recovery. In the end, the Arctic sea ice extent fell to just 3.4 million square kilometers (1.32 million square miles) when only a few months ago scientists were wondering if it would break the 4 million square kilometers. The speed of the sea ice decline due to climate change has outpaced all the computer models, overrun all expert predictions, and shocked even the gloomiest scientists.
Another mishap kills Shell's Arctic oil drilling for the year
(09/18/2012) Following global protests, a series of embarrassing mishaps, and a lengthy regulatory process, Dutch Royal Shell has announced it is abandoning its hugely controversial off-shore oil drilling in the Arctic—this year. The announcement came after the company damaged a containment dome meant to cap an oil spill. The incident was the latest in a series of delays and problems that oil the giant faced in its $4 billion plan to drill in the Chukchi and Beaufort Seas.
Coral reefs in Caribbean on life support
(09/11/2012) Only 8 percent of the Caribbean's reefs today retain coral, according to a new report by the International Union for Conservation of Nature (IUCN). With input and data from 36 scientists, the report paints a bleak picture of coral decline across the region, threatening fisheries, tourism, and marine life in general.
Featured video: Chasing Ice trailer
(09/11/2012) A new film, opening in the U.S. in November, follows the exploits of National Geographic photographer, James Balog, as he attempts to photograph the end of glaciers and great ice sheets, which are diminishing and, in some cases, collapsing under the heat of global climate change. The film, which won a cinematography award at Sundance, documents the lengths one person will go to capture images of a vanishing world.
Wind can power the world, says two new studies
(09/10/2012) Wind power is up to the challenge of providing more-than-enough energy for global society, according to two new and unrelated studies. Both studies, one published in Nature Climate Change and the other in the Proceedings of the National Academy of Sciences (PNAS), found that wind power from surface winds alone could produce hundreds of terrawatts (TW) meanwhile current global society uses around 18 TW.
Shell begins offshore drilling in the Alaskan Arctic
(09/10/2012) With the approval of the Obama Administration, Royal Dutch Shell began drilling into the ocean floor of the Chukchi Sea off the coast of Alaska yesterday morning. The controversial operation, which has been vehemently opposed by environmental and Native groups, will likely only last a few weeks this year until the Arctic winter sets in. The U.S. government has said that Shell must complete operations by September 24th, however the oil giant has asked for an extension.
Amazon deforestation could trigger drop in rainfall across South America
(09/06/2012) Deforestation could cause rainfall across the Amazon rainforest to drop precipitously, warns a new study published in the journal Nature. Using a computer model that accounts for forest cover and rainfall patterns, Dominick Spracklen of the University of Leeds and colleagues estimate that large-scale deforestation in the Amazon could reduce basin-wide rainfall 12 percent during the wet season and 21 percent in the dry season by 2050. Localized swings would be greater.
Obama approves preparation for oil drilling in Arctic, Shell en route
(08/30/2012) In the same week that sea ice in the Arctic Ocean hit another record low due to climate change, the Obama Administration has given final approval to Royal Dutch Shell to prepare for exploratory drilling in the region. Vehemently opposed by environmentalists and indigenous groups, the drilling plans are a part of the Obama Administrations 'all of the above' energy policy. Whether or not Shell will actually drill a well this season, however, is still up in the air as its oil spill containment barge remains docked in Washington state for an upgrade that could last several days.
Sea ice falls to record low with over two weeks of melting left
(08/27/2012) One of the most visible impacts of climate change—melting summer sea ice in the Arctic—just hit a new milestone. Scientists with the U.S. National Snow and Ice Data Center (NSIDC) have declared that this year's Arctic sea ice extent dipped below the previous record set in 2007 as of yesterday. The record is even more notable, however, as it occurred more than a fortnight before the Arctic's usual ice melt season ends, meaning the old record will likely not just be supplanted, but shattered.
Greenpeace abandons occupation of Arctic oil drilling rig after workers throw metal at them
(08/26/2012) On Friday the head of Greenpeace, Kumi Naidoo, and five other activists occupied an Arctic oil platform owned by Russian oil and gas giant Gazprom to protest exploiting fossil fuel beds in the Arctic ocean. The action by Greenpeace was short-lived after workers began spraying them with cold water from high-powered hoses and then threw pieces of metal at them, according to Naidoo, who communicated via Twitter during the civil disobedience.
Arctic sea ice approaches another record melt
(08/22/2012) Sea ice extent in the Arctic is very near to beating the previous record low set in 2007, according to the U.S. National Snow and Ice Data Center. Researchers told Reuters that they expect the record to be beaten by the end of month, well over a week before the melt season ends in the frozen north.
Pictures of the day: NASA captures stunning images of U.S. wildfires at night
(08/21/2012) NASA is now able to capture satellite images of wildfires—at night. Using the The Suomi National Polar-orbiting Partnership satellite (S-NPP), which has instruments that are particularly sensitive to light, NASA was able to take images of fires burning nocturnally across the American West in what has been a record year, to date, for fires in the country.
Shell running out of time to drill in U.S. Arctic - this year
(08/20/2012) The clock is running out for oil giant, Royal Dutch Shell, to drill controversial oil wells in the U.S. Arctic before the harsh winter sets in, reports the Wall Street Journal and Bloomberg. While the company is still optimistic it can reach the Arctic by summer's end, it awaits a number of final permits after suffering numerous setbacks, including one of its drilling ships going adrift and nearly running aground in Alaska.
Fourth warmest July yet around the world
(08/20/2012) Last month was the fourth warmest July in the record books going back to 1880 worldwide, according to new data released by the National Oceanic and Atmospheric Administration (NOAA). It was notably warmer in the Northern Hemisphere than in the South: the month was the warmest July ever in the North. Worldwide temperatures were 0.62 degrees Celsius (1.12 degrees Fahrenheit) above the 20th Century average.
Greenland suffers record melt
(08/16/2012) Four weeks before Greenland's melting season usually ends, it has already blown past all previous records. By August 8th, nearly a month before cooler weather usually sets in around the world's largest island, the island toppled the past record set in 2010.
United States ranks near bottom on first ever energy efficiency scorecard
(08/15/2012) Last month, the American Council for an Energy Efficient Economy released its first ever international energy efficiency scorecard, which gave the United Kingdom the top score. Using data points honed over years of rating U.S. states, the organization hoped to inspire nations to learn from each others' effective policies, as well as encourage "friendly competition" in the spirit of lowering global carbon emissions. At number one, the United Kingdom achieved a score of 67 out of 100 points, followed by Germany, Italy and Japan. As a whole, the European Union tied with China and Australia, and nine points below them, the United States came in with a score of 47 out of 100.
Climate change may be worsening impacts of killer frog disease
(08/13/2012) Climate change, which is spawning more extreme temperatures variations worldwide, may be worsening the effects of a devastating fungal disease on the world's amphibians, according to new research published in Nature Climate Change. Researchers found that frogs infected with the disease, known as chytridiomycosis, perished more rapidly when temperatures swung wildly. However scientists told the BBC that more research is needed before any definitive link between climate change and chytridiomycosis mortalities could be made.
July 2012: hottest month in U.S. history
(08/08/2012) Last month was not only the hottest July in U.S. weather history, but the hottest month ever recorded in the contiguous U.S, besting a record struck in July 1936 during the Dust Bowl, according to new data from the National Oceanic and Atmospheric Administration (NOAA). The average temperature last month over the contiguous U.S. was 77.6 degrees Fahrenheit, or 3.3 degrees Fahrenheit above the 20th Century average. Making matters worse, crippling drought continued to spread over 63 percent of the lower 48 states.
Climate and culture: abrupt change and rapid response
(08/06/2012) As the world experiences record heat, increased drought and fires, unprecedented ice melt and similar extreme weather anomalies decades before expected, climatologists have been forced to reconsider previous climate change projections and research techniques. Less than a decade ago, scientific consensus considered warming of more than 2 C and atmospheric levels of carbon dioxide near 450 parts per million (ppm) as acceptable or "safe". Revised climate science literature and expert opinion now regard safe atmospheric levels of carbon dioxide as below 350 ppm, or less than 1 C rise in average planetary temperature. Many researchers and environmentalists, however, recognize that the present deviation from pre-industrial temperatures of 0.8 C may be unacceptable to prevent runaway climate change and widespread disasters.
Earth's ecosystems still soaking up half of human carbon emissions
(08/06/2012) Even as humans emit ever more carbon dioxide into the atmosphere, Earth's ecosystems are still sequestering about half, according to new research in Nature. The study finds that the planet's oceans, forests, and other vegetation have stepped into overdrive to deal with the influx of carbon emitted from burning fossil fuels, but notes that this doesn't come without a price, including the acidification of the oceans.
Extreme heatwaves 50 to 100 times more likely due to climate change
(08/05/2012) A recent rise in deadly, debilitating, and expensive heatwaves was caused by climate change, argues a new statistical analysis published in the Proceedings of the National Academy of Sciences (PNAS). Climatologists found that extreme heatwaves have increased by at least 50 times during the last 30 years. The researchers, including James Hansen of NASA, conclude that climate change is the only explanation for such a statistical jump.
Jungles in Antarctica? High CO2 levels contributed to tropical conditions on the icy continent 50M years ago
(08/02/2012) Tropical vegetation grew along the coast of Antarctica 52 million years ago, an indication to dramatic climate shifts linked to elevated carbon dioxide levels in the atmosphere, report scientists in Nature.
Tigers vs. coal in India: when big energy meets vanishing cats
(08/01/2012) Burning coal fuels climate change, causes acid rain, and spreads toxic pollutants into the environment, but now a new Greenpeace report warns that coal may also imperil the world's biggest feline: the tiger. Home to world's largest population of tigers—in this case the Bengal subspecies (Panthera tigris tigris)—India is also the world's third largest coal producer. The country's rapacious pursuit of coal—it has nearly doubled production since 2007—has pushed the industry into tiger territory, threatening to destroy forests and fragment the tiger's already threatened population.
Drought pits farmers against frackers
(08/01/2012) Drought has created a standoff over water supplies in the U.S. Midwest between energy producers and farmers, reports Bloomberg. Natural gas and oil producers have been forced to seek new water sources as they mull calls from farmers and activists to recycle their water, a practice that would make 'fracking' more expensive.
Prominent climate skeptic reverses course, says global warming worse than IPCC forecast
(07/30/2012) After starting his own project to study global warming, a once-prominent climate change skeptic and physicist says he now accepts the reality of anthropogenic climate change. "Last year, following an intensive research effort involving a dozen scientists, I concluded that global warming was real and that the prior estimates of the rate of warming were correct. I'm now going a step further: Humans are almost entirely the cause," Richard Muller writes in the New York Times as his team, the Berkeley Earth Project, releases a new paper that finds an even stronger link between greenhouse gas emissions and rising temperatures worldwide than the Intergovernmental Panel on Climate Change (IPCC).
Featured video: climate change bringing on the extremes
(07/24/2012) Focusing on extreme weather events in the U.S. this summer, a new compilation video highlights the connection between climate change and increasing and worsening extremes, such as heatwaves, droughts, and floods.
U.S. drought could set in motion global food crisis
(07/23/2012) The U.S. is suffering drought levels not seen in over 50 years—and drawing comparisons to the Dust Bowl—with 56 percent of the contiguous U.S. in moderate to extreme drought. Some experts fear that the drought, and resulting hikes in food prices, could propel another global food crisis like those seen in 2008 and 2010.
Drought, heat, fires push more Americans to accept reality of climate change
(07/19/2012) Record temperatures, wildfires, drought, and crop failures have is helping convince more Americans that climate change is real and occurring, reports Bloomberg.
China's per capita emissions nearly as high as Europe's
(07/19/2012) The average person in China emitted 7.2 tons of carbon last year, according to new figures from BL Netherlands Environmental Assessment Agency and the European commission's Joint Research Centre (JRC). This means that the average Chinese citizen is now very close to the average European, who emits 7.5 tons, in terms of annual emissions. Having been named the world's largest emitter of greenhouse gases in 2009—usurping the U.S. from its long-held position—China continues to lead the pack with emissions that rose 9 percent in 2011.
Borneo's forests face dire future from global warming
(07/18/2012) Already wracked by extensive deforestation and forest degradation, the future looks grim for Borneo's tropical rainforests, reports a new study published in the Journal of Geophysical Research-Biogeosciences.
Scientists: iron fertilization could be a big climate help
(07/18/2012) For a long time, oceanic iron fertilization was seen as a promising mechanism to combat global climate change. But then in 2009 a well-publicized study found that iron fertilization stored 80 times less carbon than expected, dampening enthusiasm and support around the geoengineering scheme. Now, however, the idea of fertilizing the ocean with iron may be back: a new study in Nature reports that iron fertilization, in the right conditions, could store carbon in the deep ocean for centuries.
First snow leopards collared in Afghanistan as species faces rising threat from climate change
(07/18/2012) Scientists have captured and collared two snow leopards (Panthera uncia), arguably one of the world's most elusive predators, in Afghanistan for the first time. Undertaken by researchers with Wildlife Conservation Society (WCS) and Afghani vets, the successful operation was conducted as a new study finds that snow leopard habitat could shrink by nearly one-third due to anthropogenic climate change in the Himalayas.
Northern Hemisphere experiences warmest June on record
(07/17/2012) The Northern Hemisphere suffered its warmest June on record across land and sea, while globally it was the fourth warmest June yet, according to new data from the National Oceanic and Atmospheric Administration (NOAA).
Republican stalwart calls global warming 'a matter of fact', pushes for carbon tax
(07/13/2012) Former Secretary of State George Shultz is calling for a carbon tax to reduce U.S. greenhouse gas emissions and oil consumption, according to an interview released today by Stanford University.
Deja vu: U.S. undergoes hottest 12 months on record...again and again
(07/12/2012) According to new data from the National Oceanic and Atmospheric Administration (NOAA)'s National Climatic Data Center, the last twelve months have been the warmest on record for the contiguous United States. This record, set between July 2011 through June 2012, beat the last consecutive twelve month record set only a month earlier between June 2011 and May 2012, which in turn beat the previous record holder, you guessed it: May 2011 through April 2012.
Scientists slam Telegraph blogger's claims that climate change will be good for the Amazon
(07/12/2012) Recent blog posts on The Telegraph and the Register claiming that tropical rainforests like the Amazon are set to benefit from climate change are 'uninformed' and 'ridiculous' according to some of the world's most eminent tropical forest scientists. The posts, published Sunday and Monday by Tim Worstall, a Senior Fellow at London's Adam Smith Institute, asserted that a new Nature study indicates that 'climate change will mean new and larger tropical forests.' But some of the world's leading tropical forest experts took aim at Worstall's logic, noting the limitations of the study as well as the other factors that are endangering rainforests.
Thousands of scientists hold mock funeral in Canada to highlight nation's "death of evidence"
(07/11/2012) Carrying signs that said 'Stop Harper's War on Knowledge' and 'Scientists Shouldn't Wear a Muzzle,' Canada's scientists were unusually theatrical yesterday at a rally against the Canadian government's cuts for basic science funding and environmental protections. Scientists, dressed in white coats, carried a coffin to represent "the death of evidence" in Canada, while a costumed grim-reaper led the way. According to police, around 2,000 joined in the protest.
Climate change increased the probability of Texas drought, African famine, and other extreme weather
(07/11/2012) Climate change is here and its increasing the chances for crazy weather, according to scientists. A prestigious group of climatologists have released a landmark report that makes the dramatic point that climate change is impacting our weather systems—and in turn our food crops, our economies, and even our lives—here-and-now. The new report in the American Meteorological Society is first of what is intended to be an annual offering that will attempt to tease out the connections between climate change and individual extreme weather events, such as heatwaves, droughts and floods.
As U.S. sees record heat, extreme weather pummels 4 continents
(07/10/2012) It's not only the U.S. that has experienced record-breaking extreme weather events recently, in the last couple months extreme weather has struck around the world with startling ferocity. In addition to the much-covered heatwaves, wildfires, and droughts in the U.S., killer floods struck India, the worst drought yet recorded plagued South Korea, and massive forest fires swept through Siberia to name just a few.
2,600 scientists: climate change killing the world's coral reefs
(07/10/2012) In an unprecedented show of concern, 2,600 (and rising) of the world's top marine scientists have released a Consensus Statement on Climate Change and Coral Reefs that raises alarm bells about the state of the world's reefs as they are pummeled by rising temperatures and ocean acidification, both caused by greenhouse gas emissions. The statement was released at the 12th International Coral Reef Symposium.
Pre-industrial deforestation still warming atmosphere
(07/03/2012) Fossil fuels were not burned in massive quantities prior to the Industrial Revolution, but humans were still pumping carbon into the atmosphere due to land use change, especially deforestation. In fact, a new study in Environmental Research Letters finds that deforestation prior to 1850 is still heating up our atmosphere today.
Scientist: 'no doubt' that climate change is playing a role in U.S. fires
(07/02/2012) A noted climate scientist says there is 'no doubt' that climate change is 'playing a role' in this year's series of record fires in the western U.S. A massive wildfire in Colorado has forced the evacuation of 36,000 people, destroyed over 300 homes, and killed two people. The devastation wrought by the Waldo Canyon Fire even prompted a visit form U.S. President Barack Obama. But this is not the only epic fire in the U.S. this year: less than a month before the Colorado disaster, New Mexico experienced its largest fire on record in Gila Nation Forest; the conflagration burned up 247,000 acres (100,000 hectares). Other major wildfires have occurred in Utah and Wyoming, as well as other parts of New Mexico and Colorado.
Climate change to favor trees over grasses in Africa
(06/29/2012) As the world warms, scientists are working rapidly to understand how ecosystems will change, including which species will benefit and which will falter. A new study in Nature finds that elevated CO2 concentrations should favor trees and woody plants over savannah and grasslands in Africa.
Cowards at Rio?: organizations decry 'pathetic' agreement
(06/20/2012) As world leaders head to Rio de Janeiro for the UN Summit on Sustainable Development, environmental and poverty groups are denouncing the last-minute text agreed on by dignitaries as "pathetic," (Greenpeace), a "damp squib" (Friends of the Earth), "a dead end" (Oxfam), and, if nothing changes, "a colossal waste of time" (WWF). "We were promised the 'future we want' but are now being presented with a 'common vision' of a polluter’s charter that will cook the planet, empty the oceans and wreck the rain forests,“ the head of Greenpeace, Kumi Naidoo, said. "This is not a foundation on which to grow economies or pull people out of poverty, it’s the last will and testament of a destructive twentieth century development model."
Rio+20 and economic perils in Europe: opportunity for linkage
(06/19/2012) This month, momentous events will occur on the global scene that will set the tone for whether 2012 will be a hopeful year or one in which dislocations and disconnects are further exacerbated by political failings. The EU will decide on its fiscal and monetary union that hinges on Greece’s recent June election, which backed the political party that wants to stay in the Euro zone, but insists on adjustments to the earlier-negotiated economic rescue package.
Scientists give world leaders 'Fs' on climate change, biodiversity, and desertification
(06/19/2012) It seems world leaders may need to retake environmental studies. As the Rio+20 Summit on Sustainable Development opens, the scientific journal, Nature, has evaluated the progress made on three treaties signed at the Rio Earth Summit in 1992: climate change, biodiversity decline, and desertification. Unfortunately the publication gives progress on all three treaties an 'F', highlighting how little progress has been made on the global environmental crisis.
Experts: ignoring climate change at Rio+20 makes other goals "meaningless"
(06/18/2012) The Climate Change Task Force (CCTF)—made up of 30 climate scientists, other experts and world leaders—warned today that sidelining climate change at the Rio+20 Summit on Sustainable Development threatened progress on the conference's other goals, which includes combating poverty and building economies that value nature. "I am very concerned and worried because the draft final document of the Rio+20 conference does not give proper attention to climate change," says former Russian President Mikhail Gorbachev in a press statement.
Second warmest May yet worldwide
(06/18/2012) Last month was the second warmest May since record-keeping of global temperatures began 132 years ago. Globally, temperatures were 0.66 degrees Celsius (1.19 Fahrenheit) above the 20th Century Average and were only topped by May 2010, according to preliminary findings by the National Oceanic and Atmospheric Administration (NOAA).
World failing to meet promises on the oceans
(06/14/2012) Despite a slew of past pledges and agreements, the world's governments have made little to no progress on improving management and conservation in the oceans, according to a new paper in Science. The paper is released just as the world leaders are descending on Rio de Janeiro for Rio+20, or the UN Summit on Sustainable Development, where one of the most watched issues is expected to be ocean policy, in part because the summit is expected to make little headway on other global environmental issues such as climate change and deforestation. But the new Science paper warns that past pledges on marine conservation have moved too slowly or stagnated entirely.
Featured video: the Rio speech heard round the world
(06/14/2012) As world leaders, officials, NGOs, businesses, and experts gather in Rio de Janeiro for the UN Summit on Sustainable Development, or more well known as Rio+20, it might be useful to look at the landmark Rio Earth Summit in 1992, which helped propel environmental concerns around the world. The most noteworthy speech during that meeting was made by a twelve year old Canadian girl, Severn Suzuki.
