Global warming 5 million years ago raised sea levels by 20 metres

Times of India: Global warming five million years ago may have caused parts of Antarctica's large ice sheets to melt and sea levels to rise by approximately 20 metres, a new study has claimed. The researchers, from Imperial College London, and their academic partners studied mud samples to learn about ancient melting of the East Antarctic ice sheet. They discovered that melting took place repeatedly between five and three million years ago, during a geological period called Pliocene Epoch, which may have caused...

Global warming drives more nighttime heatwaves
2013-07-23 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Summit Voice: A trend of more frequent nighttime heatwaves in the Pacific Northwest may not portend killer temperatures and withering crops, but it is another sign that global warming will have a profound effect on regional climate and weather. Scientists with the Oregon Climate Service at Oregon State University documented 15 examples of nighttime heat waves from 1901 through 2009. Ten of them have occurred since 1990 and five were during a four-year period from 2006-09. The research shows that the region...

Global warming 'on pause' but set to resume
2013-07-23 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Telegraph: Surface temperatures around the world have not increased on average since the late 1990s, causing some sceptics to suggest that climate change is not happening as quickly as experts predict. But in a set of three new reports, the Met Office claims that global warming has been disguised in recent years by the oceans, which have absorbed greater amounts of heat and prevented us from noticing the difference at surface level. This process, caused by the natural cycle of the oceans, could delay...
Global Warming Linked with Frequent Fires in Alaska's Boreal Forests

Nature World News: A new study from the University of Illinois has shown that Yukon Flats of interior Alaska, one of the most flammable regions of the world, is seeing more frequent and severe fires now than it had in the past 10,000 years. Researchers attribute this increase to global warming. Recently, large wildfires in Alaska have charred more than half a million acres at a time, The Los Angeles Times reported. Another recent study had found that wildfires may drive up global warming by releasing more carbon-containing...

Dangerous global warming could be reversed, say scientists
2013-07-14 14:21:00| Climate Ark Climate Change & Global Warming Newsfeed
Grist: Global warming could be reversed using a combination of burning trees and crops for energy, and capturing and storing carbon dioxide underground (CCS), according to an analysis by scientists. But experts cautioned that trying such an approach after temperatures had passed dangerous levels could be problematic, as climate change reduced the number of trees available for "bioenergy." The bioenergy and CCS method was the most cost-effective way of tackling carbon emissions, said the team at Chalmers...
