Its official: We can now say global warming has made some weather events worse
By Chris Mooney March 11 at 10:10 AM
From Hurricane Katrina to Superstorm Sandy, to last years devastating heat wave in India, the question never ceases to arise: Did global warming cause this?
That question has long made scientists squirm. They know the atmosphere is a complicated place. They know weather events are the result of a huge array of factors like, say, the El Niño event that has been making weather really, really weird lately. And they know their notion of causation itself is far more complex and multifaceted than the colloquial understanding of the term cause.
But now, says a new report from the National Academy of Sciences exploring the attribution of extreme events to climate change, scientists can be at least a little bit less conservative about this.
In the past, a typical climate scientists response to questions about climate changes role in any given extreme weather event was we cannot attribute any single event to climate change, says the report, which was composed by a committee of 10 scientists led by David Titley of Penn State University. The science has advanced to the point that this is no longer true as an unqualified blanket statement.
