The nature of initial glaciation on Antarctica about 34 million years ago is a mystery.

New York, Boston and other cities on North America's northeast coast could face a rise in sea level this century that would exceed forecasts for the rest of the planet if Greenland's ice sheet keeps melting as fast as it is now, researchers said on Wednesday.

A Nepali sherpa who holds the world record for climbing Mount Everest said on Monday rising temperatures were melting snow and turning the slopes barren, making it even harder to scale the world's tallest peak.

Experts Worry Melting Permafrost May Release More Gas

Oslo: A rise in concentrations of a powerful greenhouse gas over the Arctic after a decade of stability is stirring worries about a possible thaw of vast stores trapped in permafrost, experts said.

NEW DELHI: The European Union has launched project

GLACIAL meltdown, global warming, devastating floods, soil erosion, rise in the sea level, salinity, waterlogging, famine, and heavy rainfall are the direct catastrophic consequences of deforestation. It is estimated that Himalayan glaciers are receding by 30 to 50 metres a year and in another 50 years they could be gone altogether.

Theory has suggested that the West Antarctic Ice Sheet may be inherently unstable. Recent observations lend weight to this hypothesis. This article reassess the potential contribution to eustatic and regional sea level from a rapid collapse of the ice sheet and find that previous assessments have substantially overestimated its likely primary contribution.

Volume changes in the Antarctic Ice Sheet are poorly understood, despite the importance of the ice sheet to sea-level and climate variability. Over both millennial and shorter time scales, net water influx to the ice sheet (mainly snow accumulation) nearly balances water loss through ice calving and basal ice shelf melting at the ice sheet margins.

Global warming began in the 18th century glaciers, both in the northern and southern hemispheres, started melting in the mid-eighteenth century, triggered by climate change. Researchers from the Wadia Institute of Himalayan Geology in Dehradun tracked the age of lichens (a composite organisms formed by the association of fungi and algae) that develop on glacial moraines and came up with

Alpine glaciers leave spectacular records of climate change. Lakes, moraines, and other landforms shaped by past glacier advances and retreats dominate the foreground of nearly all mountain landscapes. These glacial deposits are rich records of past climate that are widespread, obvious, and easily accessible.
