Ending Geoengineering Prematurely Worsen Global Warming
2014-02-19 19:17:00| Climate Ark Climate Change & Global Warming Newsfeed
RedOrbit: Starting and then stopping geoengineering techniques could aggravate global warming, scientists warn. A proposed mitigation technique which involves spewing sulfur particles into the atmosphere could help combat climate change but if stopped after being implemented, it could worsen the problem, according to a new study from University of Washington researchers. Spewing sulfur particles into the air could cool the planet by reflecting sunlight back into space a technique called solar radiation...

Global warming: Warning against abrupt stop geoengineering method
2014-02-17 07:00:00| Climate Ark Climate Change & Global Warming Newsfeed
ScienceDaily: As a range of climate change mitigation scenarios are discussed, University of Washington researchers have found that the injection of sulfate particles into the atmosphere to reflect sunlight and curb the effects of global warming could pose a severe threat if not maintained indefinitely and supported by strict reductions in greenhouse gas (GHG) emissions. The new study, published today, 18 February, in IOP Publishing's journal Environmental Research Letters, has highlighted the risks of large...

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,...

Gore Rejects Climate Change Geoengineering
2014-01-20 14:54:00| Climate Ark Climate Change & Global Warming Newsfeed
CleanTechnica: Former U.S. vice-president Al Gore pulled no punches about geoengineering in a phone conference with reporters on Wednesday. He was apparently reacting to a suggestion in a leaked draft summary of the forthcoming climate solutions section of the UN Intergovernmental Panel on Climate Change fifth climate assessment report. The definitive study, to be released in Germany in April, suggests that before 2100, the world`s national governments may have to use massive geoengineering programs such as...

Al Gore says use of geo-engineering to beat off climate disaster is insane
2014-01-15 19:58:00| Climate Ark Climate Change & Global Warming Newsfeed
Guardian: Al Gore said on Wednesday it would be "insane, utterly mad and delusional in the extreme" to turn to geo-engineering projects to avoid a climate catastrophe. The UN climate panel, in the next edition of its blockbuster reports, will warn that governments might have to extract vast amounts of greenhouses gases from the air by 2100 to limit climate change, according to a draft copy of the report seen by Reuters. But the former vice president of the US said that searches for an instant solution,...
