Stu Ostro, leader of the Weather Channel’s team of tornado, hurricane and climate experts just outside the Perimeter, describes himself as a reformed skeptic when it comes to the topic of man’s impact on climate.
But in a post over the weekend, Ostro raised the ultimate question: “Did global warming ‘cause’ the Atlanta flood?”
The post is long and complex, with charts and graphs as tough to wade through as Pumpkinvine Creek was 10 days ago. But here’s his summary toward the end:
…There’s a straightforward connection in the way the changing climate “set the table” for what happened this September in Atlanta and elsewhere. It behooves us to understand not only theoretical expected increases in heavy precipitation (via relatively slow/linear changes in temperatures, evaporation, and atmospheric moisture) but also how changing circulation patterns are already squeezing out that moisture in extreme doses and affecting weather in other ways.
In other words, the answer is yes.
