Global warming 'will make lightning strike more'

A US research says that the Climate Change will significantly increase the frequency of lightning strikes, triggering more wild fires.

The research, published in Science, used data from US National Lightning Detector Network, which detects an electromagnetic pulse every time lightning strikes in the US.

The warmer environment will provide more energy to "fuel" storm clouds and make the thunderstorms more energetic.

"For every two lightning strikes in 2000, there will be three lightning strikes in 2100," said David Romps, at the University of California, Berkeley.
