Ex-IPCC Head: Prepare for 5°C Warmer World

The world has missed the chance to keep greenhouse gas emissions below the level needed to prevent the temperature climbing above 2° Celsius, according to the British scientist who used to chair the IPCC, the Intergovernmental Panel on Climate Change.… Read More

Snow-loving Wolverines Threatened by Climate Change

Snow-loving Wolverines Threatened by Climate Change

When 18th century zoologists gave the largest land-dwelling member of the weasel family the scientific name Gulo gulo — which translates, not so roughly, to gluttonous glutton — they were foreshadowing what would be mankind’s rather one-dimensional view of the creature we now know as the wolverine. The black-and-white, 30-pound, bushy-tailed … Read More

Looking for Love as the Climate Heats Up

The interbreeding has several consequences, none well understood: It could increase genetic diversity, helping species weather rapid ecosystem changes. It also could dilute the genetics of at-risk animals such as polar bears – perhaps even diluting them beyond recognition. And the changes threaten to wreak havoc with conservation efforts. Not all e… Read More

Tigers in Mangrove Forest Face Climate Change Threat

Tigers in Mangrove Forest Face Climate Change Threat

A vast mangrove forest shared by India and Bangladesh that is home to possibly 500 Bengal tigers is being rapidly destroyed by erosion, rising sea levels and storm surges, according to a major study by researchers at the Zoological Society of London (ZSL) and others.… Read More

Climate Change a Bigger Extinction Threat than Asteroids

Climate Change a Bigger Extinction Threat than Asteroids

As teaching moments go, it doesn’t get much better than this. NASA scientists have known for nearly a year that a small asteroid called 2012 DA14, about 150 ft. across, would whiz past Earth at the nail-biting distance of 17,000 miles or so — significantly closer than the 22,500-mile altitude occupied by geosynchronous satellites. It happened right… Read More

NOAA Head: Weather Forecasts at Risk Over Budget Cuts

NOAA Head: Weather Forecasts at Risk Over Budget Cuts

Automatic budget cuts set to take effect March 1 could add to the woes of the federal government’s troubled weather satellite programs, jeopardizing future forecasts, a top official said yesterday. “It’s not going to be pretty,” outgoing National Oceanic and Atmospheric Administration chief Jane Lubchenco said of the package of across-the-board … Read More

Good News, Bad News Continues for Drought Across U.S.

Good News, Bad News Continues for Drought Across U.S.

Thursday’s release of the latest U.S. Drought Monitor brought slivers of good news for some parts of the continental U.S., while more bad news for other regions. Storms that swept across the Southeast over the past week made a significant dent in drought conditions, eradicating the areas of “exceptional” drought — the worst category. Those rains … Read More

Thinning Ice Is Turning Arctic into an Algae Hotspot

Thinning Ice Is Turning Arctic into an Algae Hotspot

Shrinking, thinning Arctic sea ice appears to be accelerating the growth of algae in polar waters, a new study finds, a development that could alter the region’s ability to absorb carbon from the atmosphere. Scientists cruising central Arctic waters last summer aboard the research ship Polarstern were stunned to discover dense, shaggy deposits of… Read More
