Find out how warm it's getting in your city

We live in the southern U.S. and are accustomed to the heat, but according to data gathered by the Climate Impact Lab, we're seeing more 90-degree days than in previous years.

"This year, we saw a lot of records being set in July," said Dr. Daniel Cohan, associate professor of environmental engineering at Rice University.

And with the fall season almost upon us, officially starting on Saturday Sept. 22, does it feel like it?

"This particular September has been relatively typical of recent Septembers so we're not seeing any extreme events right now," said Dr. Cohan. He studies atmospheric models and said that has not been the case in recent years.

"We just lived through three straight years of having 500-year storms in Houston so climate change is redefining what it means to have extreme rain events," said Dr. Cohan.

Think back to Harvey. That storm system dumped more rain than any other tropical system ever recorded.

"Storms are getting more extreme and actually, research going on at Rice has already found that for Houston," said Dr. Cohan. He also said the current warming climate is different than past cycles.

"What's unique about the latest global warming, relative to other events of the past 1,000 years, is almost the whole world is warming at once," said Dr. Cohan.

"Probably over the last twenty years, I've seen thirty days delay in the hummingbirds coming through," said Tom Hopwood. He also said he has noticed a change just in his lifetime. All Hopwood needs to do is look at nature.

"Usually, these climate changes happen so slowly that we don't see them in a lifespan," said Hopwood. "Now, it's speeding up to a pace that I think people might see it if they live in the same city from their childhood to adulthood and old age."

"There's so much unknown," said Dr. Cohan. "So much that we don't know what will happen because we're carrying out this worldwide experiment unlike anything that humans have ever experienced."

Hopwood agrees with Dr. Cohan. "Maybe we're not supposed to be here at all," added Hopwood. "Maybe what's the great denial is nature will do it's thing whether we're here or not."

Dr. Cohan cautioned that climate is the study of weather over a long period of time so we shouldn't get caught up on singular events. He does believe we need to be doing our part whether that's driving eco-friendly cars, consuming clean energy or even changing our diet.
