Ice melting across globe at accelerating rate, NASA says

CNN – December 16, 2008

This story about the rapid melting of ice in the major cold areas of the world (Greenland, Antarctica, and Alaska) needs to cause everyone concern. While the story doesn’t convincingly discuss the causality of the situation, it does point out that increased melting accelerates the planets warming due to loss of reflectivity of the “white” ice.

The article goes on to point out the increase of pine beetles which is theorized to be attributed to a warmer environment. It even goes so far as to predict the increase in sea level (ala Al Gore) by the end of the century based on this loss of ice.

Between 1.5 trillion and 2 trillion tons of ice in Greenland, Antarctica and Alaska have melted at an accelerating rate since 2003, according to NASA scientists, in the latest signs of what they say is global warming.

NASA’s Gravity Recovery and Climate Experiment, or GRACE, mission uses two orbiting satellites to measure the “mass balance” of a glacier, or the net annual difference between ice accumulation and ice loss.

Melting ice, especially in Greenland and the Arctic, is also thought to contribute to global warming, Zwally said. When the vast ice sheets and glaciers melt, they lose their reflective power, and instead, oceans and land absorb the heat, causing the Arctic waters and the atmosphere to warm faster.

As an example, he cited the pine beetle infestation of this summer in the forests of Colorado and western Canada.

”The best estimates are that sea levels will rise about 18 to 36 inches by the end of the century, but because of what’s going on and how fast things are changing, there’s a lot of uncertainty,”

  1. This is the most comfortable situation for the agw-scientists: They can predict something nearly nobody alive can proof in the future!

    Today I asked my Grandma about the future of the sea level: she predicts: plus about 300 mm until year 2100.

    Let me tell you something: I believe in my Grandma much more than every media-greedy scientist and agw-nerd. 🙂
