Many nations wary of extracting carbon from air to fix climate http://apocadocs.com/s.pl?1397041051
Many nations want a draft U.N. report to tone down prospects for sucking greenhouse gases from the air to help fix global warming, reckoning the technologies are risky, documents seen by Reuters show.
Government officials and scientists are meeting in Berlin this week to edit the report, which says time is running out to keep warming below an agreed ceiling of 2 degrees Celsius (3.6 Fahrenheit) over pre-industrial times....
China, the European Union, Japan and Russia were among nations saying the draft, to be published on Sunday, should do more to stress uncertainties about technologies that the report says could be used to extract carbon dioxide from the atmosphere and bury it below ground to limit warming.
Carbon dioxide removal (CDR) "technologies are currently not available and would be associated with high risks and adverse side-effects," the German government said in a comment on the draft by the Intergovernmental Panel on Climate Change (IPCC).
"There are no CDR technologies by now," Russia said. The technologies would go far beyond the traditional focus on cutting emissions from burning coal, oil or natural gas.
