Arctic melt causes more climate problems than anticipated

Graham Readfern

The amount of heat absorbed by the dark ocean exposed by the melting Arctic ice-cap could be as much as one quarter of all the heat trapped by man-made carbon dioxide.

FOR 50 YEARS or so, scientists have warned that if Arctic ice melts then the planet will be less able to reflect the sun’s energy and further fuel global warming.

Now, a new study using more than 30 years of satellite measurements has confirmed this hypothesis, warning that melting Arctic ice is having a greater impact on the world’s energy balance than previously thought.

One response to “Arctic melt causes more climate problems than anticipated

    James Hansen has long said that equilibrium climate sensitivity is likely to be considerably greater than 3°C, based on much evidence including paleo data. The denialists have sought at every turn to minimise the estimation of ECS, and they pounce on noise in the current signal in order to achieve their goal, but more and more is is becoming apparent that Hansen’s big picture understanding is moving ever more to centre stage. As oceanic partitioning, albedo, aerosols, clouds and other factors become better understood, the picture becomes more and more grim.

    We should be worried, and our children should be terrified.
