State of the Climate in Asia 2024
<p>The World Meteorological Organization’s State of the Climate in Asia 2024 report warns that the region is warming nearly twice as fast as the global average, driving more extreme weather and posing

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.

Gore urges humans to burn less fuel to curb 'black carbon'
By John Vidal, The Guardian Gore warned that all the world's icy regions were experiencing rapid and dangerous global warming. The world must burn less diesel and wood, Nobel peace prize-winner Al Gore said, as the soot produced is accelerating the melting of ice in polar and mountainous regions.

High-frequency Holocene glacier fluctuations in New Zealand differ from the Northern Signature
Understanding the timings of interhemispheric climate changes during the Holocene, along with their causes, remains a major problem of climate science. Here, we present a high-resolution 10Be chronology of glacier fluctuations in New Zealand

Antarctic - NYC- sized ice slab breaks off
An area of an Antarctic ice shelf almost the size of New York City has broken into icebergs in April after the collapse of an ice bridge widely blamed on global warming, a scientist said on Tuesday.
