With the warming of planet Earth, one of its affects is more moisture in the atmosphere and thus the greater risk for heavy precipitation events because more moisture is being evaporated into the atmosphere. According to Climate Central, “for every 1ยฐF of warming, the saturation level is increased by about four percent.” The below map highlights each region’s percent change in heavy precipitation events across the United States based onย the precipitation in the heaviest one percent of rainfall days.

Then we take a look at this next graphic, highlighting the annual one-plus inch rainfall days compared to average. Notice how the trend has been an increase in the number of these days, once again taking us back to the increasing occurrence of heavy rain and flooding. Climate Central claims that “the rain from Hurricane Harvey (2017) over Texas was about three times more likely and 15 percent more intense from climate change.”
