Drought stalls tree growth and shuts down Amazon carbon sink
A recent drought completely shut down the Amazon Basin's carbon sink, by killing trees and slowing their growth, a ground-breaking study led by researchers at the Universities of Exeter and Leeds has found. Previous research has suggested that the Amazon - the most extensive tropical forest on Earth and one of the "green lungs" of the planet - may be gradually losing its capacity to take carbon from the atmosphere. This new study, the most extensive land-based study of the effect of drought on Amazonian rainforests to date, paints a more complex picture, with forests responding dynamically to an increasingly variable climate.... Co-author Professor Oliver Phillips, from the University of Leeds, said: "For more than 20 years the Amazon has been providing a tremendous service, taking up hundreds of millions more tonnes of carbon every year in tree growth than it loses through tree death. But both the 2005 and 2010 droughts eliminated those net gains."
New study confirms water vapor as global warming amplifier
"The study is the first to confirm that human activities have increased water vapor in the upper troposphere," said Brian Soden, professor of atmospheric sciences at the UM Rosenstiel School and co-author of the study.... Using the set of climate model experiments, the researchers showed that rising water vapor in the upper troposphere cannot be explained by natural forces, such as volcanoes and changes in solar activity, but can be explained by increased greenhouse gases, such as CO2.... Climate models predict that as the climate warms from the burning of fossil fuels, the concentrations of water vapor will also increase in response to that warming. This moistening of the atmosphere, in turn, absorbs more heat and further raises the Earth's temperature.

Arctic sea ice hits a record low wintertime maximum
The Arctic Ocean ice cap peaked for the winter on 24 March at 14.52 million square kilometres - a record low and 20,000 square kilometres less than the previous record low maximum extent. The 13 smallest maximum extents on the satellite record have happened in the last 13 years. Record high temperatures were recorded in December, January and February around the world. In the Artic average air temperatures were up to 5.5 degrees C above average at the edges of the ice pack.

New Paper Suggests Catastrophic Climate Shifts May Be Decades Away
Using computer models, evidence from ancient episodes of climate change, and modern observations, Hansen and his team arrived at one essential conclusion: The melting of the Greenland and Antarctica ice sheets will set off a vicious cycle that dramatically accelerates the pace of climate change. The key concept here is ocean "stratification," a process by which cold, fresh meltwater rises to the ocean surface while warmer salt water is pushed beneath. (The Washington Post notes that an "anomalously cold 'blob' of ocean water" has been detected off the southern coast of Greenland.) That warmer salt water would eventually reach the base of the ice sheets, melting them from below, thus spurring more stratification, which would then spur more melting, which would then spur more stratification, which would spur more warming, until our grandchildren are all swallowed by the sea. But that's not all! Hansen's paper also projects that the influx of cold meltwater in the North Atlantic region, combined with warmer equatorial waters, would drive midlatitude cyclones so strong, the waves would be capable of thrusting gigantic boulders ashore.

Winter ice coverage in Arctic sea reaching record low, scientists warn
Scientists warn that the area covered by this winter's Arctic sea ice could turn out to be the lowest ever measured. The news comes on top of a long season of freakishly warm weather at the top of the planet, including above-freezing days at the North Pole and a months-long string of temperature records. "The winter, overall, has been extremely warm in the Arctic," said Ted Scambos, a glaciologist at the National Snow and Ice Data Centre in Colorado.
Degrading ice wedges reshape Arctic permafrost and landscape
The wedges, which can be the size of a house, gradually formed over hundreds or even thousands of years as water seeped into permafrost cracks. On the ground surface, they form polygon shapes roughly 15-30 meters wide--a defining characteristic of northern landscapes.... Ice wedge degradation has been observed before in individual locations, but this is the first study to determine that rapid melting has become widespread throughout the Arctic. "Here we're combining observations from people working in the field across the Arctic--Russia, Canada and Alaska--where we're seeing the same ice wedge melting phenomenon," said Liljedahl, the lead author of the study.... "It's really the tipping point for the hydrology," Liljedahl said. "Suddenly you're draining the landscape and creating more runoff, even if the amount of precipitation remains the same. Instead of being absorbed by the tundra, the snowmelt water will run off into lakes and larger rivers. It really is a dramatic hydrologic change across the tundra landscape."
CO2 in the atmosphere rose more in 2015 than scientists have ever seen in a single year
... "Carbon dioxide levels are increasing faster than they have in hundreds of thousands of years," Pieter Tans, lead scientist of NOAA's Global Greenhouse Gas Reference Network, said in a statement. The rate of increase in carbon dioxide concentrations is 200 times faster than the previous extreme jump between 11,000 and 17,000 years ago, when levels rose 80 ppm over about 6,000 years.... Michael Mann, an atmospheric science professor and director of the Earth System Science Center at Penn State University, who is unaffiliated with NOAA, said the carbon dioxide milestone shouldn't be over-interpreted. "This spike is almost certainly due in substantial part to the ongoing El Niño event, which is a fleeting effect that increases carbon dioxide concentrations temporarily," Mann said. "Carbon dioxide concentrations are a lagging indicator, and they don't accurately reflect recent trends in the more important variable -- our actual carbon emissions."

Seas are now rising faster than they have in 2,800 years, scientists say
"We can say with 95 percent probability that the 20th-century rise was faster than any of the previous 27 centuries," said Bob Kopp, a climate scientist at Rutgers University who led the research with nine colleagues from several U.S. and global universities.... The new research also forecasts that no matter how much carbon dioxide we emit, 21st-century sea level rise will still greatly outstrip what was seen in the 1900s. Nonetheless, choices made today could have a big impact. For a low emissions scenario, it finds that seas might only rise between 24 and 61 centimeters. In contrast, for a high emissions scenario -- one that the recent Paris climate accord pledged the world to avert -- they could rise as much as 52 to 131 centimeters, or, at the very high end, 4.29 feet.

"The Blob" Disrupts What We Think We Know About Climate Change, Oceans Scientist Says
When the abnormally warm patch of water first appeared in 2013, fascinated scientists watched disrupted weather patterns, from drought in California to almost snowless winters in Alaska and record cold winters in the northeast. The anomalously warm water, with temperatures three degrees Centigrade above normal, was nicknamed The Blob by U.S climatologist Nick Bond. It stretched over one million square kilometres of the Gulf of Alaska -- more than the surface area of B.C. and Alberta combined -- stretching down 100-metres into the ocean. And, over the next two years that patch of water radically affected marine life from herring to whales. Without the welling-up of cold, nutrient-rich water, there was a dearth of krill, zooplankton and copepods that feed herring, salmon and other species. "The fish out there are malnourished, the whole ecosystem is malnourished," said Richard Dewey, associate director for science with Ocean Networks Canada, speaking at Shaw Ocean Discovery Centre in Sidney on Thursday.... It could be an indication of what climate change will look like, with large-scale shifts in weather patterns, said Dewey, pointing out that The Blob was not anticipated by climatologists because it did not fit into existing climate models. "Climate change may look like a whole new model we haven't seen before," Dewey said.

Climate change disaster is biggest threat to global economy in 2016, say experts
A catastrophe caused by climate change is seen as the biggest potential threat to the global economy in 2016, according to a survey of 750 experts conducted by the World Economic Forum. The annual assessment of risks conducted by the WEF before its annual meeting in Davos on 20-23 January showed that global warming had catapulted its way to the top of the list of concerns. A failure of climate change mitigation and adaptation was seen as likely to have a bigger impact than the spread of weapons of mass destruction, water crises, mass involuntary migration and a severe energy price shock - the first time in the 11 years of the Global Risks report that the environment has been in first place.

What scientists just discovered in Greenland could be making sea-level rise even worse
Rising global temperatures may be affecting the Greenland ice sheet -- and its contribution to sea-level rise -- in more serious ways that scientists imagined, a new study finds. Recent changes to the island's snow and ice cover appear to have affected its ability to store excess water, meaning more melting ice may be running off into the ocean than previously thought.... Through on-the-ground observations, the scientists have shown that the recent formation of dense ice layers near the ice sheet's surface are making it more difficult for liquid water to percolate into the firn -- meaning it's forced to run off instead.
Climate Disruption Amplifies Atlantic Currents' Contribution to Sea Level Rise
Anthropogenic climate disruption (ACD) has progressed to a point where it is, literally, changing one of the most important ocean circulatory currents in the world. In a paper recently published in the journal Geophysical Research Letters, NASA researchers confirmed that the circulation of the Atlantic meridional overturning circulation (AMOC) is slowing down. In 2009 and 2010 that shifting had already been linked to a sudden and extreme five-inch sea level rise on the East Coast.

Bad news: Scientists say we could be underestimating Arctic methane emissions
"...The fact that this was done not just at one site, but multiple sites, is a breakthrough in our ability to quantify [methane] budgets for tundra ecosystems." The researchers found that cold-season methane emissions are not only not negligible -- they're pretty significant. While emissions varied somewhat from one site to the next, Zona said that, overall, emissions from September to May accounted for about half of all the methane emitted from those sites throughout the entire year. This might seem a little baffling when you consider the fact that methane is generally released as Arctic soil thaws -- a process that should be most pronounced during the warmest part of the year. Zona said the key to understanding where cold-season emissions come from lies in the way Arctic soil is structured and how it reacts to changes in temperature.
Sao Paulo on emergency reserve water; drought means Brazilian hydropower falls short
... The main water supply in São Paulo has been running on emergency reserves, and the system is only able to deliver about 40 percent of its usual capacity. Before 2014, it was able to supply approximately 8,700 gallons of water per second, but now, it only delivers around 3,500 gallons per second. Because two-thirds of Brazil's power comes from hydroelectric power plants, electricity has also been in short supply. Widespread blackouts have hit the country's largest cities, and increased energy rationing is a possibility, which could stunt the economy....
Overheated Planet Entering 'Uncharted Territory at Frightening Speed'
With new evidence that the concentration of greenhouse gases broke yet another record in 2014, the head of the World Meteorological Organization (WMO) warned on Monday that the warming planet is hurtling "into uncharted territory at a frightening speed." The United Nations weather agency's latest Greenhouse Gas Bulletin (pdf) reports that atmospheric concentrations of carbon dioxide (CO2) reached 397.7 parts per million (ppm) in 2014, substantially beyond the 350ppm level deemed "safe" by scientists to avoid global warming.... "Every year we report a new record in greenhouse gas concentrations," Jarraud continued. "Every year we say that time is running out. We have to act NOW to slash greenhouse gas emissions if we are to have a chance to keep the increase in temperatures to manageable levels."

The New Climate "Normal": Abrupt Sea Level Rise and Predictions of Civilization Collapse
... As if that's not enough, Hansen's study comes on the heels of another study published in Science, which shows that global sea levels could rise by at least 20 feet, even if governments manage to keep global temperature increases to within the agreed upon "safe" limit of 2 degrees Celsius.... Disconcertingly, another new "normal" this month comes in the form of huge plumes of wildfire smoke over the Arctic. At the time of this writing, well over 12 million acres of forest and tundra in Canada and Alaska have burned in wildfires, and the smoke covering the Arctic sea ice is yet another anthropogenic climate disruption (ACD) amplifying feedback loop that will accelerate melting there. The additional smoke further warms the atmosphere that quickens the melting of the Arctic ice pack.... "The results show that based on plausible climate trends, and a total failure to change course, the global food supply system would face catastrophic losses, and an unprecedented epidemic of food riots," the Institute's director, Dr. Aled Jones, told Insurge Intelligence. "In this scenario, global society essentially collapses as food production falls permanently short of consumption."...

Climatologists' Psyches: When the End of Human Civilization Is Your Day Job

Is Box representative of all of the scientists most directly involved in this defining issue of the new century? How are they being affected by the burden of their chosen work in the face of changes to the earth that could render it a different planet?... Among climate activists, gloom is building. Jim Driscoll of the National Institute for Peer Support just finished a study of a group of longtime activists whose most frequently reported feeling was sadness, followed by fear and anger.... And many scientists now think we're on track to 4 or 5 degrees--even Shell oil said that it anticipates a world 4 degrees hotter because it doesn't see "governments taking the steps now that are consistent with the 2 degrees C scenario." That would mean a world racked by economic and social and environmental collapse. "Oh yeah," Schmidt says, almost casually. "The business-as-usual world that we project is really a totally different planet. There's going to be huge dislocations if that comes about." But things can change much quicker than people think, he says. Look at attitudes on gay marriage. And the glaciers? "The glaciers are going to melt, they're all going to melt," he says.... And the rising oceans? Bangladesh is almost underwater now. Do a hundred million people have to move? "Well, yeah. Under business as usual. But I don't think we're fucked." Resource wars, starvation, mass migrations . . . "Bad things are going to happen. What can you do as a person? You write stories. I do science. You don't run around saying, 'We're fucked! We're fucked! We're fucked!' It doesn't--it doesn't incentivize anybody to do anything."

Ocean currents disturb methane-eating bacteria
Offshore the Svalbard archipelago, methane gas is seeping out of the seabed at the depths of several hundred meters. These cold seeps are a home to communities of microorganisms that survive in a chemosynthetic environment - where the fuel for life is not the sun, but the carbon rich greenhouse gas.... There is a large, and relatively poorly understood, community of methane-consuming bacteria in this environment. They gorge on the gas, control its concentration in the ocean, and stop it from reaching the ocean surface and released into the atmosphere.... "We were able to show that strength and variability of ocean currents control the prevalence of methanotrophic bacteria", says Lea Steinle from University of Basel and the lead author of the study, "therefore, large bacteria populations cannot develop in a strong current, which consequently leads to less methane consumption."
Sea Level Rise Is Happening Faster Than Anyone Thought

"Sea level rise is getting faster. We know it's been getting faster over the last two decades than its been over the 20th century and its getting faster again." Because sea levels can naturally fluctuate as water is exchanged between land and sea, Watson notes that the rate of increase is too small to be statistically significant -- though he told the Washington Post that it's clear that sea levels are now rising at roughly double the rate observed in the 20th century, something that will have potentially huge ramifications for coastal areas across the world.

"Preliminary indications are that methane is reaching the ocean surface - this is the first time this has been measured in New Zealand," he said. "However, to understand how much methane, and then what this means for atmospheric contributions, will require detailed analysis of the data."... The discovery of this high concentration of gas flares in shallow water depths - 100m-300m - on an active tectonic subduction zone was unique, as gas seeps usually occurred much deeper, at 600m to 1000m below the surface. The team identified methane gas in the sediment and in the ocean, and vast areas of methane hydrates - ice-like frozen methane - below the seafloor. This year's research voyage continued the work of an international project focusing on the interactions between gas hydrates and slow-moving landslides called SCHLIP - Submarine Clathrate Hydrate Landslide Imaging Project.
How Long Can Oceans Continue To Absorb Earth's Excess Heat?
The ocean has been heating at a rate of around 0.5 to 1 watt of energy per square meter over the past decade, amassing more than 2 X 1023 joules of energy -- the equivalent of roughly five Hiroshima bombs exploding every second -- since 1990. Vast and slow to change temperature, the oceans have a huge capacity to sequester heat, especially the deep ocean, which is playing an increasingly large uptake and storage role. That is a major reason the planet's surface temperatures have risen less than expected in the past dozen or so years, given the large greenhouse gas hike during the same period, said Kevin Trenberth, senior scientist with the National Center for Atmospheric Research... But scientists say that when the cycle eventually swings back to its positive, warm phase, which history suggests could occur within a decade, the winds will wind down, the pumping will let up, and buried heat will rise back into the atmosphere. "There's a hint this might already be starting to happen," said Matthew England, an ocean sciences professor at the University of New South Wales in Sydney, Australia.... Scientists are also learning that the ocean has gained more heat, and at greater depth, than they had realized. That means the entire climate is even more out-of-whack than is evident today.... The long-term heat gain in the top 700 meters (.43 miles) of the world’s oceans has likely been underestimated by as much as half, according to Lawrence Livermore National Laboratories research scientist Paul Durack.
Antarctica is basically liquefying
Antarctica's icy edges are melting 70 percent faster in some places than they were a decade ago, according to a new study in the journal Science. These massive ice shelves serve as a buffer between the continent's ice-sheet system and the ocean. As they disintegrate, more and more ice will slip into the sea, raising sea levels by potentially huge amounts. This study is just the latest bit of horrible news from the bottom of the world. Last year, we found out that the West Antarctic ice sheet was in terminal collapse, which could raise sea levels by 10 to 15 feet over a few hundred years. Then, earlier this month, we learned that an enormous glacier on the other side of the continent is in the same state, and could contribute about the same amount to sea-level rise.... But the bad news doesn't seem likely to stop anytime soon: On Monday and Tuesday, it was a balmy 63 degrees Fahrenheit at the bottom of the world, a record high.

Town council hears need for snow equipment
"It's just an exceptional (winter)," Funk said, noting six major snow storms in February and extreme temperature changes that have made it impossible to do things like popularly plowing back intersections. "I've been in the snow business for 35 years and the number of (flash) freezes this winter is unusual," he said. "The equipment has worked well. It's just not up to the winter we've had. We can hope this is not a bell weather of climate change to come."
Smithsonian Stands By Wildly Misleading Climate Change Exhibit Paid For By Kochs
But what may be most shocking of all is that the Smithsonian hasn't fixed the misleading evolution exhibit at its National Museum of Natural History, which thoroughly whitewashes the dangers of modern-day climate change. This "Hall of Human Origins" was made possible by a $15 million grant from billionaire polluter David Koch. It has now been five years since Climate Progress exposed the myriad flaws in the exhibit, a story the New Yorker and others picked up. Last week I spent some time going through the exhibit again with Dr. Lise Van Susteren, a psychiatrist and climate expert who has been featured by The Smithsonian. We were both stunned by the "Don't worry, be happy" picture it paints of current climate change.... In particular, the most embarrassing and scientifically misleading display the Smithsonian designed -- which directly suggests that humans can simply evolve to deal with global warming -- is still in the exhibit. The final section about the present and future has a nonsensical interactive video that lets visitors create a "future human" who evolves over a long period of time to a variety of changing conditions.

New records detail how climate-change views scuttled an artist's grant
A British Columbia artist and environmental activist accuses government of misusing its censorship powers to hide a politically driven effort to silence her because of her views on climate change and the oilsands. Franke James found herself on the federal government's radar in the spring of 2011 after Canadian diplomats agreed to offer a $5,000 grant in support of a European art tour featuring James's artwork. The grant was revoked a few days later by a senior director of the Foreign Affairs Department's climate change division, who felt the funding would "run counter to Canada's interests."... In one, a departmental trade official notes that a Canadian diplomat in Europe would not help promote the show because of "the artist's views on the oilsands."... Another email sent to the NGO Nektarina stated the reasons for the defunding decision "are not something we are able to provide in writing."

Arctic sea ice maximum reaches lowest extent on record
Arctic sea ice appears to have reached its maximum extent for the year on February 25 at 14.54 million square kilometers (5.61 million square miles). This year's maximum ice extent is the lowest in the satellite record. NSIDC will release a full analysis of the winter season in early April, once monthly data are available for March.
from Washington Post:
The melting of Antarctica was already really bad. It just got worse.
A hundred years from now, humans may remember 2014 as the year that we first learned that we may have irreversibly destabilized the great ice sheet of West Antarctica, and thus set in motion more than 10 feet of sea level rise. Meanwhile, 2015 could be the year of the double whammy -- when we learned the same about one gigantic glacier of East Antarctica, which could set in motion roughly the same amount all over again. Northern Hemisphere residents and Americans in particular should take note -- when the bottom of the world loses vast amounts of ice, those of us living closer to its top get more sea level rise than the rest of the planet, thanks to the law of gravity.

March: Arctic sea ice near its all-time winter low and could break previous record
Sea ice in the Arctic is near its all-time minimum for the end of winter and could break the previous record within the next two weeks if it fails to grow, according to the latest satellite data. The area of the Arctic covered by floating sea ice is already the lowest for this time of year, highlighting the long-term warming trend experienced by the region in both winter and summer months. Sea ice expands and contracts with the seasons but satellite data collected since the 1970s shows that it is retreating further and further during the summer months compared to 20 or 30 years ago. Sea ice in summer has shrunk by 30 per cent on average over the past 30 years while average temperatures in the Arctic have risen by about 4C - more than 3C warmer than the global average.

In Florida, officials ban term 'climate change'
The state of Florida is the region most susceptible to the effects of global warming in this country, according to scientists. Sea-level rise alone threatens 30 percent of the state's beaches over the next 85 years. But you would not know that by talking to officials at the Florida Department of Environmental Protection, the state agency on the front lines of studying and planning for these changes. DEP officials have been ordered not to use the term "climate change" or "global warming" in any official communications, emails, or reports, according to former DEP employees, consultants, volunteers and records obtained by the Florida Center for Investigative Reporting.
Seeds of war
Manmade global warming helped spark the brutal civil war in Syria by doubling to tripling the odds that a crippling drought in the Fertile Crescent would occur shortly before the fighting broke out, according to a groundbreaking new study published on March 2. The study, published in the journal Proceedings of the National Academy of Sciences, is the first to attribute the drought in Syria in large part to global warming. In doing so, it provides powerful evidence backing up the Pentagon and intelligence community's assessments that climate change is likely to play the role of a "threat multiplier" in coming decades, pushing countries that are already vulnerable to upheaval over the edge and into open conflict.

Jim Inhofe Brings A Snowball To The Senate Floor To Prove Climate Change Is A 'Hoax'
The Senate's most vocal critic of the scientific consensus on climate change, Jim Inhofe of Oklahoma, tossed a snowball on the Senate floor Thursday as part of his case for why global warming is a hoax.... "In case we have forgotten, because we keep hearing that 2014 has been the warmest year on record, I ask the chair, 'You know what this is?'" he said, holding up a snowball. "It's a snowball, from outside here. So it's very, very cold out. Very unseasonable."
Most Americans see combating climate change as a moral duty
A significant majority of Americans say combating climate change is a moral issue that obligates them - and world leaders - to reduce carbon emissions, a Reuters/IPSOS poll has found. The poll of 2,827 Americans was conducted in February to measure the impact of moral language, including interventions by Pope Francis, on the climate change debate. In recent months, the pope has warned about the moral consequences of failing to act on rising global temperatures, which are expected to disproportionately affect the lives of the world's poor.... Two-thirds of respondents (66 percent) said that world leaders are morally obligated to take action to reduce CO2 emissions. And 72 percent said they were "personally morally obligated" to do what they can in their daily lives to reduce emissions.

Documents Reveal Fossil Fuel Fingerprints on Contrarian Climate Research
After finishing a study contending that solar activity is increasing global warming, scientist Willie Soon of the Harvard-Smithsonian Center for Astrophysics reported his news to a utility company that was a major funder of his work.... The communications show that Soon called his peer-reviewed research papers "deliverables" in return for funding from fossil fuel companies. In addition, the documents reveal that Soon and Harvard-Smithsonian gave the coal utility company the right to review his scientific papers and make suggestions before they were published. Soon and Harvard-Smithsonian also pledged not to disclose Southern's [Southern Company Services, a mega utility company in the southeastern U.S. that generates power largely from coal] role as a funder without permission.

Think of Earth, not just your stomach, panel advises
The nation's top nutritional panel is recommending for the first time that Americans consider the impact on the environment when they are choosing what to eat, a move that defied a warning from Congress and, if enacted, could discourage people from eating red meat... the panel's findings, issued Thursday in the form of a 571-page report, recommended that Americans be kinder to the environment by eating more foods derived from plants and fewer foods that come from animals. Red meat is deemed particularly harmful because of, among other things, the amount of land and feed required in its production.
1 in 4 Americans Apparently Unaware the Earth Orbits the Sun
A National Science Foundation study involving 2,200 participants find that about 25 percent of Americans got this question wrong: 'Does the Earth go around the sun, or does the sun go around the Earth?'... And the fact that only 74 percent of participants knew that the Earth revolved around the sun is perhaps less alarming than the fact that only 48 percent knew that humans evolved from earlier species of animals.

New GOP Senate begins assault on Obama's climate rules
... Republicans on the Senate Environment and Public Works Committee attempted to poke holes in the administration's carbon rules, calling the regulations "costly," "job killing," and "unnecessary."

Methane emissions from natural gas industry higher than previously thought
World leaders are working to reduce greenhouse gas emissions, but it's unclear just how much we're emitting. In the U.S., the Environmental Protection Agency (EPA) has a new program to track these emissions, but scientists are reporting that it vastly underestimates methane emissions from the growing natural gas industry. Their findings, published in two papers in the ACS journal Environmental Science & Technology, could help the industry clamp down on "superemitter" leaks.

Most Republicans Say They Back Climate Action, Poll Finds
An overwhelming majority of the American public, including half of Republicans, support government action to curb global warming, according to a poll conducted by The New York Times, Stanford University and the nonpartisan environmental research group Resources for the Future. In a finding that could have implications for the 2016 presidential campaign, the poll also found that two-thirds of Americans said they were more likely to vote for political candidates who campaign on fighting climate change. They were less likely to vote for candidates who questioned or denied the science that determined that humans caused global warming.

Ohio renewable energy policies spurred growth, now driving away business, report says
Ohio's renewable energy policies sparked tremendous investment in the industry, but recent moves by state lawmakers have slowed that growth and threaten its future, according to a report released Tuesday. Ohio was No. 13 in the country for new capacity and private investment in wind at the end of 2012, according to the Pew report. However, new investment halted in 2013 because of "uncertainty" created by legislative debate over Ohio's renewable energy standards and the expiration of a federal production tax credit, according to the report.

Time is running out on climate denial -- But is it running out fast enough?
In short, if we take action to slow global warming, the worst case scenario involves draconian government regulations that trigger an economic recession. If we don't, the worst case scenario involves an economic recession too, but also a host of other global and societal catastrophes. Although Craven doesn't look at the probabilities of these worst case scenarios, they're also heavily weighted towards the case for taking action to curb global warming. There are lots of options to slow global warming that don't involve drastic government regulation, and that can even be beneficial for the economy. If we decide that we've gone too far in cutting carbon pollution, it's relatively easy to scale back government policies.... In other words, if we take too much action to curb climate change, the worst case scenario (upper left grid) is easily avoided. If we don't take enough action, we may not be able to avoid some of the worst consequences in the bottom right grid.

Delaware-size gas plume over West illustrates the cost of leaking methane
The methane that leaks from 40,000 gas wells near this desert trading post may be colorless and odorless, but it's not invisible. It can be seen from space. Satellites that sweep over energy-rich northern New Mexico can spot the gas as it escapes from drilling rigs, compressors and miles of pipeline snaking across the badlands. In the air it forms a giant plume: a permanent, Delaware-sized methane cloud, so vast that scientists questioned their own data when they first studied it three years ago.... The country's biggest methane "hot spot," verified by NASA and University of Michigan scientists in October, is only the most dramatic example of what scientists describe as a $2 billion leak problem: the loss of methane from energy production sites across the country.

At least 24 killed in Malaysia, Thailand floods as 200,000 evacuated
Severe flooding in Malaysia and Thailand has killed at least 24 people and forced the evacuation of more than 200,000, according to official data reported Sunday. Northeastern Malaysia and southern Thailand are regularly hit by flooding during the annual northeast monsoon, but this year the rain has been particularly heavy. Scientists have predicted that as climate change worsens, storm patterns will become less predictable and more severe.... Malaysian Prime Minister Najib Razak toured some of the worst-hit areas this weekend, stopping in Kelantan where the number of displaced people doubled to over 80,000 from Friday, following his return from a vacation in Hawaii on Friday. Najib was criticized for his absence during the calamity, after being photographed playing golf with U.S. President Barack Obama.
How the 'War on Coal' went global
Congressional Republicans who vow to defeat President Barack Obama's "War on Coal" can do little to defend the industry against a growing international threat -- the drying up of its once-promising markets overseas. Just a few years ago, domestic producers had high hopes for selling coal to energy-hungry Asia, but prices in those markets are plummeting now amid slowing demand and oversupply, ceding much of the market space to cheaper coal from nations like Indonesia and Australia. Meanwhile, a lot of U.S. coal can't even get out of the country, thanks to greens' success in blocking proposed export terminals in Washington state and Oregon. And China, the world's most voracious coal customer, just pledged to cap its use of the fuel and is promising to curb its greenhouse gas pollution.
