Records temps in Alaska, and cold here in central CONUS Colorado, wildly fluctuating jet stream from AGW, excessively heavier atmospheric moisture load again from AGW. Melt water from tundras are a problem up there, worse than ever. Siberia will probably keep up record temps, too and more methane 'blowholes' with measured CH4 spikes.

Huge amounts of carbon are contained in sediments, soils and vegetation in the Arctic. Rising temperatures in the Arctic threaten to cause much of this carbon to be released to the atmosphere.
On May 23, 2015, temperatures in Alaska were as high as 91°F (32.78°C), as illustrated by the image below.

High temperatures were reached at the city of Eagle, located on the southern bank of the Yukon River, at an elevation of 853 ft (260 m). High temperatures at such a location will cause meltwater, aggravating the situation well beyond the local area.

Carbon contained in soils will thus become increasingly exposed under the combined impact of rising temperatures and the associated growing amounts of meltwater. The meltwater can additionally cause erosion further downstream, thus making carbon at many locations become more prone to be consumed by microbes and released into the atmosphere in the form of carbon dioxide and methane.
A recent study found that, at a location where the Kolyma river in Siberia carved into the permafrost and exposed the carbon, microbes converted 60% of the carbon into carbon dioxide in two weeks time.
Gary Houser, who recently launched the movie Sleeping Giant in the Arctic, elaborates on the threat of emissions from thawing permafrost:
This immense release would likely feed on itself, raising temperatures that continue melting more and more permafrost in a vicious, frightening, and unstoppable cycle. A tipping point could well be crossed, at which time human intervention is no longer possible. Temperatures across the planet could soar, setting in motion catastrophic levels of drought and food shortage. All life support systems on earth and life forms themselves could be placed under severe stress.
The colossal scale of the danger - and the observation of those factors lining up that could trigger it - demand that humanity exercise the precautionary principle. All political decision-making related to carbon emissions must be based on the understanding that a catastrophic consequence is looming, and the window of time for prevention quickly diminishing."

I wonder what the 'normal' difference in temp from AK to CONUS is, or was before. It was a difference of 30*F from here, and no one here has every seen it quite like this with severe storms and flooding, and about a week past the historic no frost days here. Climate fluctuation beyond historic is among the first effects of CAGW. I wonder what would happen to the jet stream(s) once even higher temps are in effect. Will the exaggerated southward and smaller width in the U shaped curves eventually become cut off and rotate into high pressure storm zones? After that, will the jet streams peter out? How big a part is El Nino playing with the moisture content, and how much extra moisture is held by the 3+*F increase of CONUS from AGW? The Arctic has been 12*F + higher in temp than previous average. Well, I was fooled by high Mar & Apr temps here and planted too soon. I need more seeds. Crop failure from AGW climate fluctuation beyond historic.
Then we have the 3 super typhoons, too;
