From a children's book:
"In The Legend of Lightning and Thunder, a traditional legend that has been told in the Kivalliq region of Nunavut for centuries, two siblings resort to stealing from their fellow villagers, and inadvertently introduce lightning and thunder into the world. This beautifully illustrated traditional legend weaves together elements of an origin story and a traditional cautionary tale, giving young readers an accessible window into centuries-old Inuit mythology that is specific to the Kivalliq region of Nunavut."
In the Arctic, the harbinger of climate change, anthropogenic global warming is causing another natural phenomenon to occur more frequently (besides coastal erosion, permafrost degradation, wild fires, etc), especially along the northern coasts. In the past, sea water would keep air temperatures too cool for thunderstorms to develop, but this is obviously changing.
Below are excerpts from a blog post by blogger/commenter Apocalypse4Real (who keeps a close eye on methane readings in the Arctic):
Iced Lightning - Lightning Strikes at 80 North
On July 8 and 9, 2016 the National Weather Service published special weather statements regarding the potential for thunderstorms in Barrow, Alaska and on the North Slope. There was not a thunderstorm reported in the media, although on July 10, 2016 there was a cloud to ground strike 15 miles from Barrow.
Curious, I decided to research the background of Arctic Coast or Arctic Ocean thunderstorms, starting with Barrow and Wainwright, Alaska.
Here's what I found, and what came at the end made my jaw drop in regard to lightning strikes and thunderstorms over the Arctic Sea Ice - and the massive changes in the last 16 years of increasing thunderstorm activity over the Arctic Ocean.
