The massive shelves of ice that ring Antarctica have been shrinking over the past couple of decades, and that could have grave implications for sea level rise. It’s not the ice shelves themselves that pose a problem: they’re mostly afloat, so when they melt or dump massive icebergs, it doesn’t affect water levels any more than melting ice cubes make your drink rise and overflow. But the ice shelves serve as massive barriers that slow the flow of glaciers out to sea. As the shelves shrink, the barrier weakens, allowing glaciers to start moving faster. And since that ice is land-based, it adds to sea level rise. For full story, click here.

While the Western drought has its claws firmly dug in, the nearly five-year drought that has gripped Oklahoma and Texas is on its last legs, thanks to recent torrents of rain, government climate scientists said Thursday. “I think the Texas drought is pretty much all but over,” Victor Murphy, climate services program manager for the National Weather Service’s Southern Region, said during a press teleconference.

A new NASA study finds the last remaining section of Antarctica's Larsen B Ice Shelf, which partially collapsed in 2002, is quickly weakening and is likely to disintegrate completely before the end of the decade. A team led by Ala Khazendar of NASA's Jet Propulsion Laboratory in Pasadena, California, found the remnant of the Larsen B Ice Shelf is flowing faster, becoming increasingly fragmented and developing large cracks. Two of its tributary glaciers also are flowing faster and thinning rapidly. For full story, click here.

Not long ago, wetlands were considered mere roadblocks to development — nuisances that had to be drained to be useful.
But appreciation for these soggy, boggy areas has grown in recent years as their role in protecting against floods and in filtering pollutants is better understood. In a new analysis by Environment Virginia, wetlands are described as both the "kidneys" of our national water system, cleaning out sediment and pollutants, and as "sponges" that soak up excess water during heavy rain events.

By the reckoning of the three main agencies that track global temperature, 2015 has so far been the warmest year in more than a century. Coming immediately after the hottest year on record, the ranking serves as a reminder of how much the globe’s overall temperature has risen thanks to the ever-growing amounts of greenhouse gases in the atmosphere.

During the past decade, Antarctica's massive ice sheet lost twice the amount of ice in its western portion compared with what it accumulated in the east, according to Princeton University researchers who came to one overall conclusion -- the southern continent's ice cap is melting ever faster.

The United States could run almost entirely on clean energy by 2050, with a larger economy, $5 trillion in savings––and no acts of Congress. That's a vision of the future as seen by Amory Lovins, a sustainability expert who talked about how to reach that goal in a presentation Tuesday at Harvard University in Cambridge, Mass. Electric vehicles, retrofits, the sharing economy and the rise of clean energy in Europe and China—all these technologies and trends show how a transition from oil, coal and nuclear power is possible, he said.

The Department of the Interior (DOI), Environmental Protection Agency (EPA), and the National Oceanic and Atmospheric Administration (NOAA) today recognized four collaborative landscape partnerships across the country where Federal agencies will focus efforts with partners to conserve and restore important lands and waters and make them more resilient to a changing climate. Building on existing collaborations, these Resilient Lands and Waters partnerships – located in southwest Florida, Hawaii, Washington and the Great Lakes region – will help build resilience in regions vulnerable to climate change and related challenges. They will also showcase the benefits of landscape-scale management approaches and help enhance the carbon storage capacity of these natural areas. For full news release, click here.

Permafrost—a vast, frozen subsurface layer of soil—covers nearly a quarter of the land in the northern hemisphere. It contains centuries worth of carbon in the form of plants that have died since the last ice age but remained frozen rather than decomposing. Now scientists are learning that the "perma" part of its name may no longer be accurate. For full story, click here.
