The Financial Times reports:
Cities along the US east coast face a looming “sea level rise crisis” from a growing number of disasters as severe as hurricane Sandy, according to research on links between extreme weather and climate change.
Human-made global warming was a factor in at least six intense weather events last year, the study shows, from the superstorm that hit New York in October to the record melting of the Arctic and US heatwaves.
Climate change also had a role in Spain’s drought and torrential New Zealand rains, though natural weather variation was a leading culprit in each case, and no strong connection was found in other prominent 2012 weather events such as the US drought.
“We don’t have evidence that we are seeing things that could not have happened without natural weather variability doing its stuff,” said Peter Stott of the UK Met Office, one of the report’s editors. “But potentially climate change can in some cases add something on top.”
