Computer models suggest that the melting West Antarctic Ice Sheet (WAIS) is melting at a rapidly accelerating rate. A new computer simulation shows that at current melting rates, the ice sheet will hit a critical point in about 60 years, and could result in a sea level rise of as much as 10 feet over the next several… »
Scientists have detected a disproportionate number of methane bubble plumes off the Washington and Oregon coast. The warming Pacific ocean may be triggering the release of this powerful greenhouse gas, which has remained frozen beneath the seafloor for thousands of years.
Polar bears are the furry poster children for the impact of warming Arctic seas, but new research says they may be able adapt and survive the loss of Arctic sea ice by foraging on land. »
Having stamped out a number of tropical diseases—including malaria—decades ago, is the United States today complacent about a rising wave of infectious disease? »
Located in the North Cascades of Washington State in the U.S., Mount Baker is one of the most heavily glaciated and snow-covered mountains in the region. But as these satellite images show, its perma-snow doesn’t look so permanent anymore. »
Scientists have long wondered whether polar bears are able to enter a physiological state resembling hibernation in response to food shortages, an adaptation some researchers have speculated could protect the species even as their hunting grounds melt away. Today, we have an answer—though it’s not the one we’ve been… »
A study led by Canadian researchers shows that bumblebees are disappearing in many areas where they lived several decades ago, and climate change is to blame.
There’s been much debate these past few years over the cause of the so-called global warming “hiatus”—a pause in the overall uptick up of Earth’s temperature due to cooling at the surface of the Pacific Ocean since the early 2000s. Did climate warming stop? Nope, we just weren’t looking deep enough. »
According to the Intergovernmental Panel on Climate Change, the world’s sea levels are poised to rise dramatically in the future — as much as 200 feet (60 meters) in some parts. China’s coastlines are considered to be among the most vulnerable areas, as conveyed by these rather disturbing maps.
The Central Intelligence Agency has announced that it’s closing down MADEA, a decades-old research program that shared classified information with scientists to study how climate change might exacerbate global security risks. »
Drought and extreme heat may significantly increase the risk of power shortages in the Western U.S. unless its utilities adopt “climate-proofing” measures, according to new research.
Antarctica’s Larsen B Ice Shelf, which has existed for at least 10,000 years, will likely crumble completely away before the end of this decade, according to a new NASA study. “Although it’s fascinating scientifically,” says JPL researcher Khazendar, who led the investigation, “it’s bad news for our planet.” »
Results published this week by NOAA indicate that the monthly global average concentration of CO2 surpassed 400 parts per million in March 2015—the first time since recordkeeping began in 1959 that the monthly average has exceeded that level worldwide. »
Earlier today, Pope Francis met with the UN Secretary-General to share his concerns about climate change — a meeting that did not go unnoticed by the Heartland Institute, a right-wing American organization known for its global warming skepticism. »
Currents in the Atlantic Ocean are slowing to dangerous levels. The Gulf Stream system is now weaker than at any time before 1901, likely due to global warming. Climate scientists warn that waning circulation could dramatically change weather in Europe, cause sea level rise along the U.S. East Coast, and impact marine… »
The climate figures for February are out, and it doesn't look good. According to a new NOAA report, global average temperature over both land and ocean surfaces for February was the second highest for the month since recordkeeping began. What's more, we just experienced the warmest year-to-date (Jan-Feb) on record. »
Despite snowpocalypse, NASA reports that last month was "the second-hottest February on record, which makes March 2014–February 2015 the hottest 12 months on record." The previous hottest 12-month period record-holder, was, of course, February 2014-January 2015. See you in hell, everybody! »
