Chris W. Landsea, science and operations officer for the National Hurricane Center, said that while the storm has weakened somewhat, it is now spread over a larger area, and “a larger hurricane can cause more storm surge,” and a larger wind field; the wind damage, in other words, can be felt over a larger area. So a slightly weaker but larger storm is “kind of a wash, as far as impacts,” he said.

I grew up in Houston and also rode out Carla as a child as well as Henrietta in Cabo as an adult. I certainly believe in climate change, but is the hurricane season really worse now? What about the 1900 Galveston hurricane? — Jackie Berry

There have always been hurricanes, and many have been profoundly destructive. The Great Storm of 1900 killed at least 6,000 people on Galveston Island, and remains the deadliest natural disaster in United States history.

But climate change isn’t about these isolated incidents. It’s the long-term trend, and the long-term trend is not good.

People remember the 1900 storm — and the haunting song about it, Wasn’t that a Mighty Storm? and Erik Larson’s book “Isaac’s Storm” — because it stands out in the damage that it did. What climate change is doing is dumping more heat into the oceans and more moisture into the air — conditions that are likely, over time, to make the strong storms that do develop become more powerful, and possibly more frequent, as well.

Katharine Hayhoe, a climate scientist at Texas Tech University, noted that while global average temperatures are rising, “20 times more heat is going into the ocean” than into the atmosphere, and so that’s a lot of power in the sea for hurricanes to draw on. And, in fact, while the 1900 storm was terribly destructive, much of that tragedy could be blamed on the lack of warning in those pre-satellite times.

It’s hard to attribute any single weather event to climate change, but it’s clear that climate change sets up conditions that can lead to more 1900 storms, more Katrinas, more Sandys. When I wrote about the science of attribution last year, Andrew E. Dessler, a climate researcher at Texas A & M, told me determining whether an extreme weather event like a flood is caused by climate change is like trying to figure out which of Barry Bonds’s home runs were caused by his steroid use.

“You know statistically some of them were, but you don’t know which ones,” he said. “Almost certainly, it would have rained a lot even without climate change — but it’s possible climate change juiced it, added a little bit.”
