This spring, more than 40 percent of the western U.S. is in a drought that the USDA deems "severe" or "exceptional." The same was true in 2013. In 2012, drought even spread to the humid east. But new research shows how short-lived but severe climatic events can trigger cascades of ecosystem change that last for centuries.
Greenland's ice sheets are melting faster than anyone predicted. Why glaciologist Jason Box's radical theory may not be so radical after all...
The expedition, called the Dark Snow Project, is the first crowd-sourced scientific research trip to Greenland. “The old ways of doing things aren’t working,” Box tells me one evening. “I want to pursue big ideas, but I also want to communicate them in ways that the public understands. Scientists need to do everything they can to wake people up. It is our job, our moral responsibility.”http://www.rollingstone.com/greenland-melting?stop_mobi=yes

BERLIN (AP) - The cost of keeping global warming in check is "relatively modest," but only if the world acts quickly to reverse the buildup of heat-trapping gases in the atmosphere, the head of the U.N.'s expert panel on climate change said Sunday.
On this Earth Day, while much of the focus will be on the dire warnings issued by the IPCC, we are offering a map that shows there is hope, possibility and opportunity. This map pinpoints communities across America that are taking the fight against climate change into their own hands by developing community-scale renewable energy and energy conservation projects. Our map highlights over 100 projects that are rooted in communities, with particular attention to communities of color, who by 2042 will become the majority in our nation. With the threat of climate change becoming more real every day, communities are coming together now to be participants, decision-makers and owners in a new energy economy. We call this Energy Democracy.
Massive wildfires are on the increase in the western USA due to rising temperatures and worsening drought from climate change, and the trend could continue in the decades to come, new research suggests.
Five anthropogenic factors that will radically alter forest conditions and management needs in the Northern United States have been outlined in a new report. "The northern quadrant of the United States includes 172 million acres of forest land and 124 million people," said one researcher. This report "is helping identify the individual and collective steps needed to ensure healthy and resilient futures for trees and people alike."
(Phys.org) —A collaborative study released today involving scientists from the Cambridge Conservation Initiative has shown that climate change is altering species distributions and populations, seemingly through shifting interactions between species rather than direct responses to climate.
Future simulations of climate in the Amazon suggest a longer dry season leading to more drought and fires. Scientists have published a new study on the impacts of fire and drought on Amazon tree mortality. Their article found that prolonged droughts caused more intense and widespread wildfires, which consumed more forests in Amazonia than previously understood.
