The rarity of humans getting struck by lightning has traditionally been a measuring stick used to assuage fears of similarly unlikely disasters: "Don't worry, you're more likely to get struck by lightning than [whatever you're worried about]." Global climate change, however, may mean we have to rethink those words of comfort, with a new estimate suggesting that lightning strikes will increase by 50% over the next century.
As if it weren't bad enough that we'll be either covered in water or facing severe droughts, scientists at UC Berkeley analyzed 11 different climate prediction models to determine that a changing atmosphere will increase the intensity of thunderstorms, causing more lightning strikes. Scary stuff!
Now, this doesn't mean that people will be dropping like flies due to lightning, but those powerful electronic discharges can have some other nasty effects. Science Dailyexplains:
