How Climate Change Likely Heightened Harvey’s Fury

Hurricane Harvey's deadly cocktail of wind and moisture hit America's fourth-largest city with a ferocity that Texas has never seen.

And while scientists maintain that no single weather event can be attributed to climate change, two centuries of human fossil-fuel burning has altered temperatures just enough to almost certainly make this particular storm worse.

"In general, the way to think about it is: climate change has changed the environment that everything is happening in," says Kevin Trenberth, a senior scientist at the National Center for Atmospheric Research in Colorado. "When you add in the climate's natural variability and then the right conditions come along, you can get a storm which is stronger than you might otherwise have expected."

In the case of Harvey, which is dumping rivers of rain in and around Houston and threatening millions of people with catastrophic flooding (see photos), at least three troubling factors converged. The storm intensified rapidly, it has stalled out over one area, and it is expected to continue dumping record rains for days and days.
