Berkeley researcher and lead author David Romps used three sets of data to show ________ warming and lightning strikes were linked. ________ looking at precipitation levels across the lower 48 states, measuring the intensity of storms, and analyzing radio signals ________ track strikes through the National Lightning Detection Network, he found strong ties between temperature and conditions ripe ________ lightning. The way Romps explains it, lightning needs all three states of water—liquid, gas, and ice—moving quickly in the atmosphere to create an electric field. When liquid water and ice swap electrons, they create a charge that translates ________ the snap of light we call lightning.

The warmer the air (thanks, greenhouse gases), ________ more water vapor the atmosphere holds, Romps says. And water vapor is “fuel ________ thunderstorms.”
