Mass loss from the glaciers along the margins of the Greenland and Antarctic ice sheets is increasingly contributing to sea level rise. However, ice loss as a result of accelerated flow, known as dynamic thinning, is so poorly understood that its potential future contribution to sea level remains unpredictable.

The two great ice sheets

U.S. wavering on climate commitment could undermine action to save the planet, the director of Germany's Potsdam Institute for Climate Impact Research said on the sidelines of a conference on Monday.

Scientists are surprised at how extensively coastal ice in Antarctica and Greenland is thinning, according to a study Wednesday that could help predict rising sea levels linked to climate change.

New satellite information shows that ice sheets in Greenland and western Antarctica continue to shrink faster than scientists thought and in some places are already in runaway melt mode.

OVER the next few days, climate change and its imminent geographic, economic and social impact will be the topic of animated discussions at a series of world fora. Beginning with the United Nations General Assembly on September 22, the debate will shift to the G-20 meeting at Pittsburgh on September 24 and culminate in the Climate Change Conference in Copenhagen in December.

This new UNEP report warns that the pace and extent of climate change may exceed even the most sobering expectations voiced by IPCC fourth assessment report. It is based on findings of more than 400 major peer-reviewed scientific studies & research institutions over the last three years.

Helping developing nations to adapt to climate change such as floods or heatwaves can give bigger economic benefits than a focus on deep cuts in greenhouse gas emissions, a study indicated on Friday.

health Side-effects stay Chemicals called contrast agents used during cardiac angiography can seriously damage kidneys which, in turn, increases chances of heart attacks. Side-effects were earlier thought to be temporary. A team tracked 294 patients exposed to contrast agents for a year. 31 per cent of the patients were found to suffer from long-term negative
