Alaska sees record temperatures in heatwave
An "all-time high" temperature record has been set in the US state of Alaska, despite much of the country sitting in the Arctic circle. Temperatures peaked at 32.22 Celsius (90F) on 4 July at an airport

As Alaska glaciers melt, sea level is falling, not rising
Juneau (Alaska): Global warming conjures images of rising seas that threaten coastal areas. But in Juneau, Alaska, as almost nowhere else in the world, climate change is having the opposite effect: As the glaciers here melt, the land is rising, causing the sea to retreat.

As Alaska glaciers decline, land rises
CORNELIA DEAN JUNEAU, ALASKA EFFECTS MORE NOTICEABLE NEAR JUNEAU AS GLACIERS RETREAT 30 FEET PER YEAR ? Global warming conjures images of rising seas that threaten coastal areas. But in Juneau, as almost nowhere else in the world, climate change is having the opposite effect: As the glaciers here melt, the land is rising, causing the sea to retreat.

Shrinking Antarctic ice threat to US cities
Washington, May 15: If the West Antarctic Ice Sheet collapses due to global warming, it would directly threaten New York, Washington and San Francisco as sea levels near US coasts would rise by 25 per cent more than the global average, according to a new study. Antarctica holds about nine times the volume of ice of Greenland.

Reassessment of the potential sea-level rise from a collapse of the West Antarctic Ice Sheet
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.

Ice sheet stability and sea level
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.

19,742 years off the mark
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

Obama Team Keeps Bush Polar Bear Climate Rule
The Obama administration said on Friday it will keep a Bush-era rule that weakens protection for polar bears' icy habitat and plays down links between the threatened status of the species and climate change. "Seeing the polar bear's habitat melting and an iconic species threatened is an environmental tragedy of the modern age," US Interior Secretary Ken Salazar said in a telephone briefing.

Variations in snow cover and snowline altitude in Baspa Basin
The Himalayas has one of the largest concentrations of glaciers and permanent snowfields outside the polar region. Snow and glacier melt forms an important source for many rivers originating in the Himalayas. Numerous studies suggest that global warming has started affecting snow melt and stream run-off in the Himalayan region.
