global warming

The scientists of the American Geophysical Union (AGU) warn that greenhouse gas (GHG) emissions must be slashed in half to keep temperatures from rising 3.6 degrees Fahrenheit (2 degrees Celsius)—or else.

Governments could slow global warming dramatically, and buy time to avert disastrous climate change, by slashing emissions of one of humanity's most familiar pollutants – soot – according to Nasa scientists. A study by the space agency shows that cutting down on the pollutant, which has so far been largely ignored by climate scientists, can have an immediate cooling effect – and prevent hundreds of thousands of deaths from air pollution at the same time.

Governments have long experience in acting against soot.

The frequency of extremely high clouds in Earth's tropics -- the type associated with severe storms and rainfall -- is increasing as a result of global warming, according to a study by scientists at NASA's Jet Propulsion Laboratory, Pasadena, Calif.

Global warming is accelerating at a faster rate than climate change experts previously predicted, according to a new summary of scientific research released today by WWF. The findings add further weight to our call for the EU to commit to real emissions cuts within Europe.

A new study by climate scientists behind the controversial 1998 "hockey stick" graph suggests their earlier analysis was broadly correct.

Michael Mann's team analysed data for the last 2,000 years, and concluded that Northern Hemisphere temperatures now are "anomalously warm".

Different analytical methods give the same result, they report in Proceedings of the National Academy of Sciences.

The 1998 hockey stick was a totem of debates over man-made global warming. <!-- E SF -->

A fungal disease that threatens to wipe out many amphibians is thriving because of climate change, a study suggests.
Researchers studying amphibians at a national park in Spain show that rising temperatures are closely linked to outbreaks of the chytrid fungus.

Chytrid fungus is a major contributor to the decline of amphibian populations around the world, threatening many species with extinction.
