California drought: Past dry periods have lasted more than 200 years, scientists say
2014-01-26 00:08:00| Climate Ark Climate Change & Global Warming Newsfeed
Mercury: California's current drought is being billed as the driest period in the state's recorded rainfall history. But scientists who study the West's long-term climate patterns say the state has been parched for much longer stretches before that 163-year historical period began. And they worry that the "megadroughts" typical of California's earlier history could come again. Through studies of tree rings, sediment and other natural evidence, researchers have documented multiple droughts in California...

United Kingdom: Climate change not main cause of floods, scientists suggest
2014-01-22 09:09:00| Climate Ark Climate Change & Global Warming Newsfeed
Telegraph: Climate change is not the main cause of floods, scientists have suggested. The debate on whether recent floods were caused by global warming is a distraction from "the things we already know for certain', according to research. Any links between climate change and flooding are "highly complex' and experts have struggled to make a case for the theory, a study has said, whereas human activity such as building on floodplains is known to make flooding worse. The Prime Minister told MPs in the...

Scientists: Geoengineering can't halt global climate change
2014-01-20 15:41:00| Climate Ark Climate Change & Global Warming Newsfeed
BDN: Bad news on the climate front. It was already clear that we are very likely to break through all the "do not exceed" limits and go into runaway warming later this century, because greenhouse emissions have not dropped, are not dropping and probably will not drop. We did have a fallback position, which was to counter the warming by geoengineering -- but now the leading technique for geoengineering also looks like it will not work. In a paper published this month in Environmental Research Letters,...

Fresh Views Climate Scientists as Advocates
2014-01-19 17:39:00| Climate Ark Climate Change & Global Warming Newsfeed
New York Times: If You See Something, Say Something, is the headline on a Sunday Op-Ed article by Michael E. Mann, the Penn State climate scientist who, after years of attacks from groups fighting restrictions on greenhouse gases, has become a prominent climate and political campaigner, as well. The piece appropriately defends the right of scientists to be citizens, fighting disinformation and pressing for action a theme explored here starting with a 2008 contribution from Richard Somerville, a longtime climate...

Climate change: When scientists become revolutionaries
2014-01-19 00:16:00| Climate Ark Climate Change & Global Warming Newsfeed
Green Left: Kevin Anderson, professor of energy and climate change at Manchester University, said on October 29 last year: Today, after two decades of bluff and lies, the remaining 2°C budget demands revolutionary change to the political and economic hegemony. Anderson is one of Britains most eminent climate scientists. He is also deputy director of the Tyndall Centre for Climate Change Research. Tyndall Centre senior research fellow and Manchester University reader Alice Bows-Larkin was more blunt...
