Greenland Ice Sheet more vulnerable to climate change than previously thought

ScienceDaily: A new model developed by researchers at the University of Cambridge has shown that despite its apparent stability, the massive ice sheet covering most of Greenland is more sensitive to climate change than earlier estimates have suggested, which would accelerate the rising sea levels that threaten coastal communities worldwide. In addition to assessing the impact of the increasing levels of meltwater created and spilled into the ocean each year as the climate continues to warm, the new model also...

California drought link greenhouse gases, climate change
2014-09-30 03:59:00| Climate Ark Climate Change & Global Warming Newsfeed
San Jose Mercury News: The stubborn high-pressure systems that block California rains are linked to the abundance of human-caused greenhouse gases that heat the oceans, according to a major paper released Monday by Stanford scientists. But two other new studies disagree -- saying there's no evidence that warming ocean waters are to blame for our drought. The dispute comes at the end of the state's official "water year," which closes Tuesday with less than 60 percent of average precipitation. California's major reservoirs...

No matter the cause, Texas must prepare for climate change

Dallas Morning News: In New York last week, President Barack Obama, scientists and national leaders from around the globe gathered to discuss the herculean task of stopping and even reversing man-made climate change. Here in Texas, the political debate over climate change has become so rancorous that some state employees appear afraid to acknowledge the reality that our climate has been changing, even if that means leaving Texans vulnerable to entirely foreseeable dangers. Our state climatologist, appointed by...

Human-Related Climate Change Led to Extreme Heat, Scientists Say

New York Times: The savage heat waves that struck Australia in 2013 were almost certainly a direct consequence of the human release of greenhouse gases, researchers said Monday. It is perhaps the most definitive statement climate scientists have made that ties a specific weather event to global warming. Five groups of researchers, using distinct methods, analyzed the heat that baked Australia for much of last year and continued into 2014, shutting down the Australian Open tennis tournament at one point in January....
Beyond climate change treaties: 'a deal in Paris is not essential'

Guardian: The United Nations Climate Summit in New York last week passed with many promises, but no firm pledges. Most notably, Chinas vice-premier Zhang Gaoli promised his country would peak its carbon dioxide emissions as soon as possible, and President Obama said that next year he would publish a plan to cut US emissions after 2020. On the fringes, major corporations trading in agricultural commodities grown on former rainforest land joined with governments in signing a declaration promising to halve...
