More evidence that climate change is feeding on itself

Cloud blanket warms up melting icecap

New study shows that up to 30% of the Greenland icecap melting is due to cloud cover that is helping to raise temperatures − and accelerate sea level rise.

LONDON, 30 January, 2016 – Researchers have identified another piece in the climate machinery that is accelerating the melting of the Greenland ice cap. The icy hills are responding to the influence of a higher command system: the clouds.

An international research team led by scientists from the Catholic University of Leuven in Belgium report in Nature Communications journal that cloud cover above the northern hemisphere’s largest single volume of permanent ice is raising temperatures by between 2° and 3°C and accounting for 20-30% of the melting.

The conclusion, based on imaging from satellites and on computer simulations, is one more part of the global examination of the intricate climate systems on which human harvests, health and happiness ultimately depend.
