Your chance of being struck by lightning is climbing, climate scientist says

By Ben Brumfield, CNN
Thanks to climate change, you'll be more likely to get struck by lightning as the years pass, scientists say. Make that 50% more likely for those who are around at the end of the century.
The logic is simple. More warmth equals more water vapor in the air, which is the fuel for thunderstorms. That equals more lightning and more of it zapping the ground. And people standing on it.
The current odds of becoming a human lightning rod in one's lifetime come in at around 1 in 12,000, the National Weather Service roughly estimates. If Romps and his colleague are right, those odds would slim to 1 in 8,000 by the year 2100.
They found they could determine fluctuations in that frequency if they knew the amount of precipitation falling and the speed and occurrence of "convective clouds" rising high into the atmosphere.
Then they studied the 11 models on projected global temperature increases to predict how much these two factors should surge in the distant future, resulting in more lightning strikes if carbon dioxide emissions continue on their current path.
