- According to a study, episodes of summer lightning within the Arctic Circle have tripled since 2010.
Why has it tripled?
- Lightning in this region is historically rare, as it usually isn’t warm enough to generate the right thunderstorm conditions during which lightning occurs.
- But due to climate change and increasing loss of sea ice in the far north, the Arctic region is warming faster than any other region on Earth.
- Hence, this has created more favorable conditions for intense summer thunderstorms that produce lightning.
Impact of Lightning on Arctic Region:
- The Arctic residents in northern Russia, Canada, Europe, and Alaska need to prepare for the danger of more frequent lightning strikes.
- Moreover, the shipping vessels throughout the Arctic could be more vulnerable to these strikes.
