Sea levels could rise up to 5 feet by the end of this century, driven by warming in the Arctic and the resulting melt of snow and ice, according to this study by the International Arctic Monitoring and Assessment Program (AMAP). This is more than two and a half times higher than the 2007 projection of a half to two feet by the Intergovernmental Panel on Climate Change.
Quickening climate change in the Arctic including a thaw of Greenland's ice could raise world sea levels by up to 1.6 meters by 2100, an international report showed on Tuesday.
Such a rise -- above most past scientific estimates -- would add to threats to coasts from Bangladesh to Florida, low-lying Pacific islands and cities from London to Shanghai.
A novel explanation for the long-term temperature record in Antarctic ice cores invokes local solar radiation as the driving agent. This proposal will prompt palaeoclimate scientists to pause and to go back to basics.
Shrinking ice and snow cover in the Northern Hemisphere is reflecting ever less sunshine back into space in a previously underestimated mechanism that could add to global warming, a study showed.
Satellite data indicated that Arctic sea ice, glaciers, winter snow and Greenland's ice were bouncing less energy back to space from 1979 to 2008.
Reliable forecasts of sea-level rise depend on accurately modelling the dynamics of polar ice sheets. A numerical framework that better reflects ice-sheet basal drag adds greater realism to such models.
This publication aims at providing an improved understanding of sea-level rise and variability to reduce the uncertainties associated with projections for sea-level rise, and hence contribute to more effective coastal planning and management.
As Greenland returns to the warm climate that allowed Vikings to colonize it in the Middle Ages, its isolated and dependent people dream of greener fields and pastures
