Voice of America: When it comes to greenhouse gases that contribute most to global warming, most people think of substances such as carbon dioxide, methane or even hydrofluorocarbons. But did you know that, for a while now, scientists have considered the vapor of the most important ingredient in sustaining life on Earth -- water -- as one of the most abundant greenhouse gases in the atmosphere and a key driver of global warming? A new study led by scientists from the University of Miami Rosenstiel School of...

African biodiversity under threat from climate change
2014-07-27 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Deutsche-Welle: Researchers meeting in Cameroon have warned that Africa could lose up to 30 percent of its animal and plant species by the end of the century because of global warming, population growth and unregulated development. It is mid-afternoon in Lom Pangar in Eastern Cameroon. People are busy working, digging holes and cleaning up. Some are cutting down trees in preparation for the construction of a new dam that could generate up to 30 megawatts of hydroelectric power. Nformi Johnson works for one of...

Study: climate change affecting fur seals in Antarctica

Blue and Green: Warming climate impacting on krill population seals primary food sources is leading to animals being born smaller and females breeding later than usual, according to new research. In a study published in the journal Nature, scientists have suggested that changes in the availability of krill small crustaceans depending on sea ice have caused Antarctic fur seals from South Georgia to become food-stressed. This has meant pups being born with 8% less body mass and females breeding later...

Climate change may slowdown crop yield, study finds
2014-07-27 11:01:00| Climate Ark Climate Change & Global Warming Newsfeed
Blue and Green: Climate change makes 20 times more likely for corn and wheat crop production to decrease, significantly affecting food prices and availability in the long-term, according to a new study. Scientist from Stanford University and the National Center for Atmospheric Research (NCAR) have said in a new study that although a massive and severe crop production slowdown is unlikely, global warming increase the risk of losses by 20 times. There is therefore a substantial risk of decreasing production of wheat...
