Predicting warming effect of human-induced greenhouse gases
The warming effect of human-induced greenhouse gases is a given, but to what extent can we predict its future influence? That is an issue on which science is making progress, but the answers are still far from exact, say ...
Ocean winds keep Antarctica cold, Australia dry
New Australian National University-led research has explained why Antarctica is not warming as much as other continents, and why southern Australia is recording more droughts.
Study identifies travel choices for a smaller carbon footprint
The study, published in the journal Environmental Science and Technology by researchers at IIASA and Center for International Climate and Environmental Research (CICERO) calculates the climate impact for pa ...
Scientists help adapt Brazil farming to climate change

Reconstructing the African humid period
During the end of the last ice age, there were dramatic changes in rainfall across a vast swath of Africa. As the world's large ice sheets receded in northern and southern latitudes, rainfall in much of Africa ...
Climate benefit for cutting soot, methane smaller than previous estimates
Cutting the amount of short-lived, climate-warming emissions such as soot and methane in our skies won't limit global warming as much as previous studies have suggested, a new analysis shows. The study also ...
Ozone-protection treaty had climate benefits, too, study says
The global treaty that headed off destruction of earth's protective ozone layer has also prevented major disruption of global rainfall patterns, even though that was not a motivation for the treaty, according ...
Climate talk shifts from curbing CO2 to adapting
Efforts to curb global warming have quietly shifted as greenhouse gases inexorably rise. The conversation is no longer solely about how to save the planet by cutting carbon emissions. It's becoming more about ...
Minimum CO2 price of $32 needed to curb warming, study shows
A global carbon price of at least $32 (24 euros) per tonne is needed by 2015 to apply an effective brake on global warming—almost five times today's European market rate, a study said Monday.
Upgraded urban travel 'could save $70 trillion by 2050'
Urban planners must re-invent city transportation systems to save up to $70 trillion globally in the next 37 years, a study said on Wednesday citing the examples of Belgrade, Seoul and New York City.
Long solo car trips as bad as air travel for climate, study says
Air travel has the biggest impact on the climate per trip, but travelling long distances alone by car could be just as bad for one's carbon footprint, a new study has found.
New global study reveals how diet and digestion in cows, chickens and pigs drives climate change 'hoofprint'
The resources required to raise livestock and the impacts of farm animals on environments vary dramatically depending on the animal, the type of food it provides, the kind of feed it consumes and where it lives, according ...
