Past Antarctic warming linked to greenhouse gas
2013-02-28 21:00:00| Climate Ark Climate Change & Global Warming Newsfeed
LiveScience: Rising carbon dioxide levels may have caused Antarctic warming in the past, new research strongly suggests. The findings, published today (Feb. 28) in the journal Science, just add to the body of evidence that human-caused greenhouse gas emissions will lead to climate change. "It's new evidence from the past of the strong role of CO2 [carbon dioxide] in climate variation," said study co-author Frédéric Parrenin, a climate scientist at the CNRS in France. Past data Eons of the Earth's climate...
Killer Heat Waves and Floods Linked to Climate Change
2013-02-27 03:06:00| Climate Ark Climate Change & Global Warming Newsfeed
Inter Press Service: Killer heat waves, floods and storms are increasingly caused by climate change, new research reveals. Scientists in Germany say they have found how greenhouse gases from burning fossil fuels are helping to trap the jet stream, resulting in extraordinary weather such as the 2010 Pakistan flood and the 2011 heat wave in the United States. Human-driven climate change repeatedly disturbs the flow of atmospheric waves around the globe`s Northern hemisphere, said lead author Vladimir Petoukhov of...

Extreme weather linked to climate change
2013-02-26 09:06:00| Climate Ark Climate Change & Global Warming Newsfeed
Agence France-Presse: Scientists said they have identified a physical mechanism behind the extreme weather that has plagued many parts of the world in recent years - and that it is tied to climate change. Since 2010, for example, the US and Russia have each suffered scorching heat waves, while Pakistan saw unprecedented flooding. Scientists from the Potsdam Institute for Climate Impact Research (PIK) have traced the events to a disturbance in the air currents in the northern hemisphere, in a new study out on Monday...

Climate change linked to declines in labour productivity
2013-02-25 00:55:00| Climate Ark Climate Change & Global Warming Newsfeed
The Conversation: Increases in humidity caused as a result of climate change are reducing labour productivity and its only likely to get worse over time, argue researchers from Americas National Oceanic and Atmospheric Administration. In an article published today in the journal Nature Climate Change, the researchers say humidity is already reducing peoples working capacity by 10% during peak months of heat stress around the world, and this is likely to grow to 20% by 2050. The researchers say even if the...
