Shrinking ice and snow cover in the Northern Hemisphere is reflecting ever less sunshine back into space in a previously underestimated mechanism that could add to global warming, a study showed.
Satellite data indicated that Arctic sea ice, glaciers, winter snow and Greenland's ice were bouncing less energy back to space from 1979 to 2008.
Climate change seems a factor in the rise and fall of the Roman empire, according to a study of ancient tree growth that urges greater awareness of the risks of global warming in the 21st century.
Good growth by oak and pine trees in central Europe in the past 2,500 years signaled warm and wet summers and coincided with periods of wealth among farming societies, for instance around the height o
World temperatures could soar by 4 degrees Celsius (7.2 degrees Fahrenheit) by the 2060s in the worst case of global climate change and require an annual investment of $270 billion just to contain rising sea levels, studies suggested on Sunday.
Such a rapid rise, within the lifetimes of many young people today, is double the 2 degrees C (3.6 degrees Fahrenheit) ceiling set by 140 governments at
The world will seek to break a U.S.-China standoff and agree modest steps to rein in global warming at U.N. talks in Mexico next week amid worries that the first climate treaty since 1992 may still be years away.
Most nations have few hopes for the meeting of environment ministers from November 29 to December 10 in the Caribbean resort of Cancun after U.S.
European nations agreed on Friday to set up fishing-free zones in remote parts of the Atlantic Ocean in the world's first high seas network of protected areas beyond the control of national governments.
Environment ministers from 15 European states, forming the OSPAR group overseeing the North-East Atlantic, said they would seek recognition of the six areas at the United Nations and from the Un
Efforts to clean up and protect the North East Atlantic have made some progress since 2000 but new threats are looming such as ocean acidification linked to climate change, a study said on Thursday.
The report, by the OSPAR Commission that groups 15 European nations and covers an area from the North Pole to the Azores, said there had been advances in reducing oil spills, discharges from nuclear
A cold snap in northern oceans around 1970 may have caused a dip in world temperatures that briefly interrupted a trend of global warming, scientists said on Wednesday.
Many experts had previously explained a slight global cooling around 1970 as a side-effect of a slow build-up of sun-dimming air pollution from factories, power plants and cars that cleared up in later years with stricter air po
