How A Warmer Climate Helped Shape Harvey

"The rain just won't stop. More than two days after Hurricane Harvey made landfall on the Texas coast, the downgraded storm continues to dump water across the region."

"So much rain has fallen in the Houston area that the National Weather Service has had to revamp its charts."

"Climate researchers agree that climate change can be partially to blame for the devastation. Here's how it has (and hasn't) shaped the course of the storm.

"Climate change may have helped Harvey to form and intensify"

"This year saw high sea surface temperatures in the Gulf of Mexico, where Harvey formed. According to an analysis published in March, the Gulf stayed above 73 degrees Fahrenheit the entire winter."

"At the time Harvey intensified into a Category 4 hurricane, it was over a section of the Gulf that was about 4 degrees above normal, says Martin Hoerling, a research meteorologist with the National Oceanic and Atmospheric Administration in Boulder, Colo."
