Leaded Gas May Have Slowed Climate Change

(Newser) - The dirty fumes of leaded gas may have curbed global warming for a few decades in the 20th century, the New Scientist reports. Researchers in Washington state have found that lead particles are key to creating ice crystals, which help form clouds—which aid global cooling by reflecting sunlight back...

EPA's Carbon Ruling Puts Heat on Congress

(Newser) - By issuing its long-awaited “endangerment finding” on carbon yesterday, the EPA is essentially putting a gun to Congress’ head, writes Bryan Walsh in Time. Capitol Hill is loathe to regulate carbon emissions, with Republicans and coal-state Democrats worried about the economic fallout. But by ruling that carbon is dangerous,...

EPA's CO2 Ruling May Have Huge Impact

The findings could result in sweeping new powers for the EPA to regulate emissions over a wide range of industries and automobiles, the AP reports. The...

Third-World Cookstoves Ignite Carbon Debate

Cutting soot could slow climate change by 18%

(Newser) - A simple $20 stove may be the ticket to slowing global warming by nearly a fifth, the New York Times reports. Soot—otherwise known as black carbon—is the second-biggest contributor to climate change, and it spews from hundreds of millions of simple stoves in developing countries daily. Installing solar-powered...

Battered Australia a Preview of Climate Devastation

Country grapples with drought, wildfires, and heat

(Newser) - Pummeled by drought, wildfires, and heat, Australia may be offering the world a preview of what’s to come as the planet warms, experts say. “Australia is the harbinger of change,” says a paleontologist. Many say climate change has already taken a human toll in the 173 killed...

White House Mulls Drastic Action on Climate Change

Geo-engineering could be last resort, Holdren says

(Newser) - Global warming may get to the point where drastic "geo-engineering" measures to cool the earth will be necessary, President Obama’s top science adviser tells the AP. John Holdren said shooting reflective particles into the upper atmosphere to reflect some sunlight is a last resort, but one he's raised...

Obama's Energy Policy Needs a Tuneup

To garner support, simplify plan and focus message: Friedman

(Newser) - Proponents of cap-and-trade, the climate policy Democrats are currently championing, argue that it “'hides the ball'—it doesn’t use the word 'tax'—even though it amounts to one," writes Thomas Friedman in the New York Times. There’s just one problem: “Opponents are not playing hide...

Post Story on Arctic Calls Out Post Columnist Will

(Newser) - George Will takes a fair amount of flak for his view that global warming is a bunch of hooey. Now he's taking it from the news pages of his own paper, writes David Roberts in Grist. A story today in the Washington Post cites evidence showing a decline in Arctic...

Nukes? Climate Change? Love 'Em to Death

Newsweek scribe lists a few issues pundits may misunderstand

(Newser) - Few so-called experts predicted the subprime meltdown or the September 11 attacks, Jacob Weisberg writes in Newsweek—so what else might the pundits be wrong about?
  • Nukes are bad: An influential political scientist “argues that possessing nukes induces restraint and caution, causing irresponsible regimes to behave more responsibly.”

Snapped Antarctica Ice Bridge Stokes Warming Alarm

First break for massive, retreating shelf

(Newser) - A massive 25-mile-long Antarctic ice bridge between a Jamaica-sized ice shelf and an island has broken in what scientists are calling an alarming sign of runaway global warming, the BBC reports. It was the first time the shelf, which has been retreating for years, has lost a link holding it...

Scientists Solve Riddle of 'Medieval Warm' Era

Finding debunks climate-change deniers

(Newser) - Atlantic ocean winds warmed Europe 1000 years ago, scientists say, scuttling a key argument used by those who deny current pollution is causing climate change. The natural regional phenomenon pinpointed as the cause of the Medieval Warm Period no longer exists and cannot be responsible for current global warming, reports...

Climate, Financial Crises Two Sides of One Coin

(Newser) - The key issue behind both the global economic and climate crises is exactly the same: “mispricing risk,” Thomas L. Friedman writes in the New York Times. “We have been mispricing risk in both arenas,” he contends, “producing a huge excess of both toxic assets and...

On Environment, White House Quick to Undo Bush Policies

Staff unearths years of shelved proposals

(Newser) - More than a dozen environmental initiatives that stagnated under former President Bush are moving forward under Obama, the Washington Post reports. In most of those cases, the decisions were based on reports drafted over several years that, in the face of opposition, were placed on the back burner to await...

Polar Bears' Other Threat: $35K Trophy Hunts

Foreign hunters spend thousands to catch dying Artic species

(Newser) - Polar bears, whose Arctic habitat is thawing out, have become the symbols of climate change, but they’re also prime targets for hunters in Canada, where trophy-hungry sportsmen cough up as much as $35,000 to bag a bear, the Independent reports. “This is probably the toughest hunt you...

Swiss-Italian Border Moves as Glaciers Melt

Alpine borderlines changing along with the climate

Global Warming Will Bring 'Global Weirding'

(Newser) - While the physical changes brought on by global warming—droughts, floods, and the like—are fairly easy to model, the effect on ecosystems is disconcertingly unpredictable, John Waldman writes in Yale Environment 360. Species will shift migration patterns and seek new homes, affecting other species in ways we can't imagine....

Warming Is Polar Bears' Top Killer, Host Nations Agree

US, Russia, Norway, Denmark and Canada sign joint statement on bear population

(Newser) - Five nations whose land is home to polar bears signed a joint statement today declaring global warming to be the biggest threat to the animals, AFP reports. Canada, Denmark/Greenland, Norway, Russia, and the US agree that “long-term conservation of polar bears depends upon successful mitigation of climate change,”...

Climate Change Doom Looms for 85% of Amazon

Death of much of the rainforest is inevitable even under most optimistic scenario

(Newser) - Climate change may be a bigger threat to the Amazon rainforest than all the chainsaws in the world, the Guardian reports. New research predicts a global temperature rise of 3.6 degrees Fahrenheit—widely believed to be the best-case scenario even if carbon emissions are slashed—would kill off up...

Sea Levels Rising Faster Than Expected

(Newser) - Top climate scientists say sea levels are rising faster than expected, the Times of London reports. The world's oceans will rise about 3 feet by the end of the century, double the amount predicted in a 2007 estimate by the UN. The new figure, blamed on melting ice sheets, could...
