CO2 emissions don’t cause hurricanes, but they do heat up water, which puts more moisture in the atmosphere and feeds the strength and speed and longevity of hurricanes. Warm water expands (pay attention, Breitbart; I know you failed 8th grade chemistry because you were sniffing glue in the toilet), which raises the sea level. Global heating also melts surface ice, which likewise raises sea level. Higher sea level contributes to higher storm surges. Climate scientist Michael Mann explains at the Scientific American, which the Breitbart folks can’t read because it is hard to hold a magazine while dragging your knuckles on the ground. Mann points out that for every degree C. of warming, you get a 26 foot per second increase in wind speed. The 2019 world average surface temperature is up nearly one degree from the 1950-1980 average.
