Climate change affecting height intensity of global oceans waves
2013-04-19 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
International Business Times: A study by Australia's Commonwealth Scientific and Industrial Research Organisation (CSIRO) has warned that the world's coastline beaches could experience swelling and intense levels and heights of pounding ocean waves due to climate change. Mark Hemer, CSIRO researcher and lead author of the study, said average annual wave heights could increase by as much as half a metre in coming decades as storm frequency and intensity in the Southern Ocean likewise increase. The heightened wave heights...

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...

Weather extremes provoked by trapping of giant waves in the atmosphere
2013-02-25 22:03:00| Climate Ark Climate Change & Global Warming Newsfeed
ScienceDaily: The world has suffered from severe regional weather extremes in recent years, such as the heat wave in the United States in 2011 or the one in Russia 2010 coinciding with the unprecedented Pakistan flood. Behind these devastating individual events there is a common physical cause, propose scientists of the Potsdam Institute for Climate Impact Research (PIK). The study will be published this week in the Proceedings of the National Academy of Sciences and suggests that man-made climate change repeatedly...

Global warming may cause extremes by slowing "planetary waves"
2013-02-25 21:14:00| Climate Ark Climate Change & Global Warming Newsfeed
Reuters: Global warming may have caused extreme events such as a 2011 drought in the United States and a 2003 heatwave in Europe by slowing vast, wave-like weather flows in the northern hemisphere, scientists said on Tuesday. The study of meandering air systems that encircle the planet adds to understanding of extremes that have killed thousands of people and driven up food prices in the past decade. Such planetary air flows, which suck warm air from the tropics when they swing north and draw cold air...
