The marine mammal was seen some 600 miles from where the river empties into the Bering Sea.

In the Glenallen area, Yukon and Kuskokwim River communities, and Northwest Arctic floodwaters caused by snow melt and rapid warming have caused many communities to be flooded.

Twenty-three of the 25 fires so far this year were ignited by human activity. While this year’s heavy snowpack and cold spring pushed back the start to fire season in many parts of the state, climate change is generally causing an earlier snowmelt, said climatologist Rick Thoman.

Anchorage-based photographer saw something wild — a sudden, bright light on the northern horizon that quickly started to take on a spiral shape as it drew nearer. The spiral “appears to be rocket engine exhaust from a SpaceX Transporter-7 mission that launched on the Falcon 9 about three hours earlier in California.”

On June 19, 2015, a slow-moving low-pressure system with spectacular thunderstorms that produced little rain began making its way through Alaska. By the time the storms finally petered out about a week later, 61,000 bolts of lightning had been unleashed on a boreal forest in the state. 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.
