Sex or nice weather. That's the agonizing choice some birds face, according to a new University of Guelph study.

A new study has revealed widespread reductions in the greenness of Amazon forests caused by the last year's record-breaking drought.

The Dalai Lama said Saturday that India should be seriously concerned about the melting of glaciers in the Tibetan plateau as millions of Indians use water that comes from there.

India's tiger population has increased for the first time in decades, a newspaper said on Saturday, citing a national tiger census report slated to be released next week.

A team of scientists from Aberystwyth University, the University of Exeter and Stockholm University, led by Welsh scientist and Professor Neil Glasser, have released at study published in Nature Geoscience showing that the glaciers of Patagonia in South America are melting at a much faster rate than originally thought.

Keeping moorland soils wet could prove vital in conserving some of Britain's important upland breeding bird species - by protecting the humble daddy longlegs, according to new research.

City buildings create their own microclimates. Ignoring these variations can make life uncomfortable for inhabitants and prevent buildings from achieving true energy efficiency, according to Evyatar Erell, a professor of architecture at Israel's Ben-Gurion University of the Negev."Even when architects design a green building, it may not make the best use of the environment because other buildings get in the way," he said.

It's ubiquitous. It's universal. And it's understood-not! Water's choices in a given situation often defy scientific predictions. When expected to bond with other water molecules, it shuns them. When expected to ignore a surface, it becomes deeply attached. However, research at Pacific Northwest National Laboratory has revealed why one of the simplest and most important molecules on the planet makes some of the decisions it does.

Melting glaciers and ice caps on Canadian Arctic islands play a much greater role in sea level rise than scientists previously thought, according to a new study led by a University of Michigan researcher.

Scientists have observed a "super-aggregation" of more than 300 humpback whales gorging on the largest swarm of Antarctic krill seen in more than 20 years in bays along the Western Antarctic Peninsula.

Along with China's rise as a world economic power have come a rapid climb in energy use and a related boost in man-made carbon dioxide emissions. In fact, China overtook the United States in 2007 as the world's leading emitter of greenhouse gases. Yet according to this new forecast, the steeply rising curve of energy demand in China will begin to moderate between 2030 and 2035 and flatten thereafter. There will come a time-within the next two decades-when the number of people in China acquiring cars, larger homes, and other accouterments of industrialized societies will peak. It's a phenomenon known as saturation. "Once nearly every household owns a refrigerator, a washing machine, air conditioners and other appliances, and once housing area per capita has stabilized, per household electricity growth will slow,'' Levine explains.

The punishment your car endures on a cold winter commute pales in comparison to the veritable torture that researchers at the U.S. Department of Energy's (DOE) National Renewable Energy Laboratory (NREL) are inflicting on two electric utility research vehicles - all in the name of science. 

According to a new study, it could become much warmer towards the end of the century than originally anticipated. The study has found that the average temperatures calculated are much higher than the IPCC's worst-case scenario to date.
