Sea Ice Is Changing Swiftly at the Poles

Posted by grant on Wednesday, 06 July 2011 in Climate Change

by fen montaigne of Yale 360 As sea ice rapidly melts in the Arctic and parts of Antarctica, the threat to creatures that use the ice as a feeding platform — polar bears and walruses in the Arctic, and Adélie penguins in the Antarctic — has been well publicized. But these iconic symbols of global ...

Extreme Heat The New Norm

Posted by Wolf on Thursday, 09 June 2011 in Climate Change

The hottest summer day you remember from childhood could be the norm in a few decades; in fact it looks like the heat has already been cranked up. "When scientists talk about global warming causing more heat waves, people often ask if that means that the hottest temperatures will become 'the ne...

Washington Should Lead on Climate Change

Posted by EarthDude on Monday, 06 June 2011 in Climate Change

Over the next two weeks, representatives from 194 nations will meet in Bonn, Germany, to push forward a deal to stabilize the global climate and help poor countries address the inevitable changes that global warming brings. Tornadoes, record-breaking heat waves, devastatin...

Is Extreme Weather Linked to Global Warming?

Posted by bchristo on Thursday, 02 June 2011 in Climate Change

In the past year, the world has seen a large number of extreme weather events, from the Russian heat wave last summer, to the severe flooding in Pakistan, to the recent tornadoes in the U.S. In a Yale Environment 360forum, a panel of experts weighs in on whether the wild weather may be ...

Arctic Access will Diminish, With Global Warming

Posted by grant on Monday, 30 May 2011 in Climate Change

Global warming over the next 40 years will cut through Arctic transportation networks like a double-edged sword, limiting access in certain areas and vastly increasing it in others, a new UCLA study predicts. "As sea ice continues to melt, accessibility by sea will increase, but the viabi...

Two Greenland Glaciers Lose Enough Ice to Fill Lake Erie

Posted by EarthDude on Wednesday, 25 May 2011 in Climate Change

A new study aimed at refining the way scientists measure ice loss in Greenland is providing a "high-definition picture" of climate-caused changes on the island. And the picture isn't pretty. In the last decade, two of the largest three glaciers draining that frozen landscape have lost enough ice tha...

Top U.S. Scientists "Global Warming. Really. We Are Not Kidding."

Posted by EarthDude on Monday, 16 May 2011 in Climate Change

by Adam Frank Last week the National Research Council, one the nation's leading scientific bodies, published yet another report on the current state of climate research. What was newsworthy about this effort was the degree to which (from my perspective) the nation's best scientists seemed to ...

Ozone Loss Made Tropics Rainier

Posted by amir on Saturday, 30 April 2011 in Climate Change

From high above the South Pole, Earth’s ozone hole can affect rainfall as far away as the tropics, scientists have found. Thinning ozone causes weather patterns to shift southward across the Southern Hemisphere, bringing more rain to a band that includes eastern Australia and the southwestern Ind...

Cooling on Global Warming

Posted by EarthDude on Wednesday, 27 April 2011 in Climate Change

"What the heck went wrong?" That, apparently, is the question roiling the environmental community as it realizes that the fight against climate change has fizzled. As Brad Plumer writes in the New Republic, everything was looking great in 2008 for a sweeping effort to make good on candidate Barac...

Snows of Kilimanjaro defy global warming predictions

Posted by ep-admin on Saturday, 19 March 2011 in Climate Change

If there is a poster child for global warming, it may be the vanishing snows of Kilimanjaro, which were predicted to disappear as early as 2015 in a widely-publicized report a decade ago. However, the famed snowcap is stubbornly persisting on the African peak and may not fully vanish for ...

The snows of Mount Kilimanjaro?

Posted by plantitfilm on Monday, 07 March 2011 in Climate Change

The first piece of that research, which looked only at the month of July, found that deforestation is changing weather patterns around the mountain but not (at least in July) at the peak, according to Dr. Udaysankar Nair, a research scientist in UAHuntsville's Earth System Science Center. ...

Is Al Gore is right about snow and climate change?

Posted by ep-admin on Thursday, 03 February 2011 in Climate Change

Even if Americans were more knowledgeable about the science of climate change, they’d have difficulty understanding the connection between a winter of extreme weather and a warming planet. A giant cold front has much of the country locked down under bitter cold and brought Chicago the most s...

Extreme Winter Killed Global Warming?

Posted by ep-admin on Wednesday, 02 February 2011 in Climate Change

The extremely cold and snowy winter of 2010-2011 may be challenging the core case of global warming. The earth is warming, the greenhouse gases are rising, and the oceans are rising… Right? This is a long-lasting debate that stirs extreme emotion from both sides of the political ...

Brazil beats US in climate change awareness

Posted by ep-admin on Tuesday, 01 February 2011 in Climate Change

[RIO DE JANEIRO] Almost 80 per cent of Brazilians think global warming is caused by human activities, a survey has found, compared with less than half of Americans and around 70 per cent of Britons according to similar recent surveys. Around 90 per cent of Brazilians believe that global w...

Arctic Waters Warmer Than 2,000 Years

Posted by ep-admin on Monday, 31 January 2011 in Climate Change

Water flowing from the North Atlantic into the Arctic Ocean is warmer today than at any time in the past 2,000 years, a new study shows. The waters of the Fram Strait, which runs between Greenland and the Arctic archipelago of Svalbard, have warmed roughly 3.5 degrees Fahrenheit over the past 1...

The True Cost Of Global Climate Change

Posted by ep-admin on Wednesday, 12 January 2011 in Climate Change

Researchers disagree about what the economic costs of climate change will be over the coming decades. But the answer to that question is fundamental in deciding how urgent it is to take action to reduce emissions. by john carey When climate legislation died last summer in Congress, one cau...
