It seems the frequency of especially heavy rain events is increasing. Is this true?

Dear Tom,
It seems the frequency of especially heavy rain events is increasing. Is this true?

Dear Edward,

Yes, and it’s probably a result of climate change. Government research indicates human activity has increased the carbon dioxide (CO2) in the atmosphere by 42 percent above pre-industrial levels. CO2 traps more heat in the atmosphere, and a warmer atmosphere holds 4 percent more water vapor for every degree rise in average temperature. These conditions mean more vigorous storms. According to NOAA scientist Ken Kunkel, once-every-five-year storms in the U.S. in 2015 occurred 80 percent more often than expected. And 12 percent more record-breaking rainstorms occurred worldwide from 1981 to 2010 than would have happened without human influence, according to Oxford
