Lightning differs by how strong it is, too. Scientists have observed mega-strikes of lightning that carry 1,000 times more energy than ordinary bolts. They’re so intense that,

Climate scientists say that rising global temperatures caused by greenhouse gas emissions are making some extreme weather events increasingly likely and severe. They predict that heat waves, wildfires, hurricanes and other weather-related disasters will continue to set records and send damage costs soaring, even as countries around the world pledge to reduce emissions in response

I wrote a short article for Science News for Kids about this finding; my snapshot was based on an original article by Alex Witze.
