No one had ever seen anything quite like it, not even in 2004, when 8,500 lightning strikes were recorded in a single day.

To varying degrees, nearly the entire state was warmer than normal this July, according to a weather expert.

Moose and other species have advanced north with warming temperatures. University of Alaska Fairbanks assistant professor of water and environmental research Ken Tape said movement of boreal species into far northern Alaska has corresponded over the last century with earlier snow-melt and river ice out.

It’s a vicious cycle: As the weather warms, the Earth’s permafrost is melting, releasing greenhouse gases that are going to make the planet even hotter.
