A massive chunk of ice, over 87 kilometres in size, has broken off the Petermann Glacier in northern Greenland. Scientists are warning that loss of the ice from this glacier is almost certain to speed up the rate at which ice from the Greenland icesheet melts into our oceans.

Melting in the Arctic, forest fires in Russia and flooding in the Himalayas are all in keeping with the predictions of climate scientists of what a warming world will look like. Nature is telling us that it is time to act, that it's time to go beyond climate changing fossil fuels and give ourselves the green and prosperous future our children deserve.

In 2009 Greenpeace supported a team of independent scientists working on the Petermann Glacier to enhance understanding of the impacts of global warming on the Greenland ice sheet.
