As we basked in 70 degree temperatures in parts of the Northeast on Sunday, just a few days in the wake of a nor’easter and nearly two weeks after Hurricane Sandy, it’s understandable that the topic of climate change is trending online.
In a post over at the Wall Street Journal’s Metropolis blog, Eric Holthaus asks the direct question: did climate change factor into recent storms?
He cites the connection between long-term sea level rise and the enhanced coastal flooding that devastated parts of Greater New York as evidence of a much clearer link between Sandy and climate change.
New York Harbor’s average water level is now 12 to 18 inches higher than it was in the 1880s, Holthaus says, and scientists estimate about 8 to 12 inches of that is a direct result of global warming. So, more people were affected in the tri-state during Hurricane Sandy than would have been if the same storm had struck in a world without climate change.
He concludes:
In another post over at Scientific American’s Observations blog, Mark Fischetti writes that scientists, journalists and even insurers are starting to drop the caveats, and simply say that climate change is causing big storms.
Fischetti suggests that as scientists collect more and more data over time, more of them will be willing to make the same data-based statements.
A recent study by Munich Re reported that North America was most affected by the rising number of natural catastrophes. Specifically, it noted a nearly five-fold increase in the number of weather related loss events in North America for the past 30 years, compared with an increase of 4 in Asia, 2.5 in Africa, 2 in Europe and 1.5 in South America.
In a press release announcing the study, Munich Re said:
