As Arctic Ice Melts, So Does The Snow, And Quickly
This 2005 photo, released by the University of Alaska, Fairbanks, shows how snow-covered Alaskan tundra reflects more light than melted areas.

Arctic snow is like lower latitude & higher altitude ices, many times locked up in mountain glaciers. As glaciers disappear, major changes occur in water run-off quantities & timings.

Before Arctic sea ice melting lets solar energy heat cold Arctic waters, snow melting on far northern lands before the summer solstice, allows the greatest solar energy to pause & reside on Earth, & even increase, as the sun approaches its greatest elevation above the horizon.

Ever wonder why they thunk like the dirtling? Do enjoy the words of wisdom so early this morning to make my day. I bet youre just as thrilled as I. Maybe you can thunk like the rest of them. Just kidding we have enough mindless thunking by the dirtling. I know what your going to say I should use my own descriptive word for thinking but I like that new word thunk presented to all by the dirtling.

Latest about Arctic sea ice melt 'and recovery':
+Barely ABOVE 4 million km2, Arctic sea ice extent is still BELOW any recorded level in any previous year for ~6 weeks, presently at 4,166,563 km2 (October 2, 2012), fractionally gaining ~25,000 km2(a bit more than West Virginia area) of sea ice the previous day, despite the sun, unseen, from the North Pole for 10+ days, & temperatures above the 80th parallel, a bit above -13 degC, fractionally above normal. Much warmth built up in Arctic waters these past months is resisting its conversion back to sea ice, especially southern Arctic waters which have seen much more solar energy absorbed than northern Arctic clear waters.
Only along the Greenland east coast is sea ice extending greatly south. All other regions, including the Northwest Passage, Northeast Passage & Arctic waters, south of the Arctic Ice Pack, resist conversion back to Arctic sea ice.
IN ADDITION, for months, any downwellings in the Arctic waters that have been ice-free, have been conducting much captured solar energy radiating on those clear waters, to the depths of the continental shelves & Arctic Ocean.
This same Arctic Ocean warmth is & will continue to keep Arctic sea ice thinner through the coming winter & even spring. As of October 2, Arctic sea ice VOLUME is ~23% lower than any satellite recorded year AND indications of submarine-detected Arctic sea ice VOLUME.
Yes, the Arctic sea ice Volume is disappearing, day to day, & year to year, quicker than the Arctic sea ice extent, even in the time of Arctic sea ice increase.

From the article:
there's the matter of fires in the boreal forests.
"If things dry out faster in the spring, then you can get more fires, and that's another trend we see in recent years, is increased fire frequency and also the size of fires," says Bret-Harte.
Our western Washington Pacific Northwest snowpack for the winter & early spring, altho late, was 150% above its normal snow depth. Our usual rains, unusually continued past June, into mid-July & only finally stopped at the end of July.
However, despite lots of previous moisture, drying occurred quickly. Before a month of drying occurred, forest fires broke out big time, first in eastern Washington, later in western Washington.
