Siachen:World’s Highest Battleground

 Siachen glacier  is billed as the world’s highest combat zone, but atrocious weather conditions have claimed more lives than actual fighting. The 77-kilometre-long (48-mile) glacier traverses the Line of Control, the de facto border separating Indian- and Pakistan-controlled Kashmir, at … Continue reading

Puncak Jaya is Dying

In Indonesia, one of the world’s last tropical glaciers is dying. Perched atop the 16,000-foot peak Puncak Jaya in Papua province, the glacier has shrunk in size by 80 percent since 1936, and most of that since the 1970s. The … Continue reading

Global Glaciation 716.5 Million Years Ago

Geologists have found evidence that sea ice extended to the equator 716.5 million years ago, bringing new precision to a “snowball Earth” event long suspected to have taken place around that time.Led by scientists at Harvard University, the team reports … Continue reading

UN climate panel blunders again over Himalayan glaciers

The IPCC had warned that climate change was likely to melt most of the Himalayan glaciers by 2035 – an idea considered ludicrous by most glaciologists. Last week a humbled IPCC retracted that claim and corrected its report. The “Glaciergate” … Continue reading

Dropstones

Dropstones are isolated fragments of rock found within finer-grained water-deposited sedimentary rocks. They range in size from small pebbles to boulders. The critical distinguishing feature is that there is evidence that they were not transported by normal water currents, but … Continue reading

Global warming isn’t the only reason why Antarctic ice shelves are falling apart

Slow tsunami-like waves are rolling into the waters off Antarctica. Generated by storms churning as near as the Patagonia coast and as far away as the Gulf of Alaska, these waves jostle the continent’s giant floating ice shelves.According to a … Continue reading

Black Carbon and Himalayan Warming

A new modeling study from NASA confirms that when tiny air pollution particles we commonly call soot — also known as black carbon — travel along wind currents from densely populated south Asian cities and accumulate over a climate hotspot … Continue reading

Antarctica’s hidden plumbing revealed

THE first complete map of the lakes beneath Antarctica’s ice sheets reveals the continent’s secret water network is far more dynamic than we thought. This could be acting as a powerful lubricant beneath glaciers, contributing to sea level rise. Unlike … Continue reading
