Stop The Darkening!

The world’s top expert says Greenland ice is getting dark and is going to kill us all

The world’s leading expert on the ice that covers the huge expanse of Greenland has told The Independent that he was “stunned” to see how much darker it has become in the past year – warning it could start a hugely damaging “cascading feedback loop” of the area becoming blacker as less and less light is reflected.

All this super deadly darkening of the snow caused below normal melt this summer.

The current darkness of the ice sheet is simply blinding

    Ummm Dr. Box? If you look at your computer monitor you will see little buttons labeled “Contrast” and “Brightness.” If newly fallen bright white snow appears “dark” you may wish to push the ^ button next to “Contrast” until white looks like white again.

    We suggest that the transport of dust from snow-free areas in the Arctic that are experiencing earlier melting of seasonal snow cover4 as the climate warms may be a contributing source of impurities. In our snow model simulations, a decrease in the albedo of fresh snow by 0.01 leads to a surface mass loss of 27 Gt yr−1, which could induce an acceleration of Greenland’s mass loss twice as large as over the past two decades5. Future trends in light-absorbing impurities should therefore be considered in projections of Greenland mass loss.

    The mid-summer melt surface in this area is pocked with 0.5 to 1 meter-wide (1.5 to 3 feet-wide) potholes with black grit and dust collected at the bottom. This black material is called cryoconite, and is comprised of dust and soot deposited on the surface, and melted out from the older ice exposed by melting. The dark patches are often glued together by tiny microbes.

    Dr. Box is in a simulation box.

    Ah, may and could once again.

    Why aren’t there any readings before 1980?

    Is it just one more thing that begins in 1979?

    Or do they not want anyone to know what the albedo of the ice was BEFORE the Clean Air Act really started to have some impact?
