Polar Bears Feel the Heat as Icy Habitat Shrinks

As climate change increasingly affects the Arctic, some polar bear populations are suffering because rising temperatures are reducing the sea ice vital for their survival.

Deep Concern Over Invisible Threat to Antarctic Glaciers

As ocean temperatures rise, warmer currents are attacking the Antarctic ice sheet from below and adding to the threats posed by a melting rate that has trebled in the last two decades.

Why Greenland Is Likely to Melt More Quickly Than Previously Expected

Scientists who have examined the role of the bedrock beneath the Greenland ice sheet think it shows the huge island is more vulnerable than realized to global warming.

Ice Melt Dilutes Arctic Sea’s CO2 Cleanup Role

New scientific research confirms that global warming is melting increasingly larger areas of Arctic sea ice—and reducing its vital function of removing CO2 from the atmosphere.

Fresh Water Causes Antarctic Seas to Rise Faster

Researchers in the U.K. have established that billions of tonnes of fresh water from melting glaciers are causing Antarctic sea levels to rise much higher and faster than the global average.

Antarctic Warming Could Accelerate Sea Level Rise

An international study says warming is affecting not only the Arctic but also the Antarctic—and that could significantly raise global sea levels much faster than previously predicted.

Human Factor Speeds Up Glacial Melting

Scientists simulating changes in mountain glaciers over the last century and half have established that rates of melting have increased greatly in recent years—and that humans are the main culprits.

Canada Puts Oil Exploitation Before Forests

Having repudiated the Kyoto Protocol on reducing greenhouse gas emissions, Canada is still exploiting tar sands for oil—despite accepting that climate change is destroying its forests.

Lakes Raise New Question on Arctic Warming

Research into the lakes that form when permafrost melts challenges the widely held view that they are contributing to Arctic temperature rise by releasing carbon into the atmosphere.

New Clue to Antarctic Food-Web Puzzle

Researchers in the U.S. say a landmark census that shows one species of penguin is thriving while other populations are in rapid decline offers new insight into how climate change is affecting Antarctica.

Whalers’ Tales Shed New Light on Arctic Ice

A new study analyzing the log books of British whaling ships’ journeys more than 200 years ago has gathered vital data on the Arctic ice sheet before extensive fossil fuel use began to affect climate.

Icebergs Strip Away Rich Antarctic Habitat

The habitat of Antarctic fauna clinging to the boulders in shallow waters is being destroyed by the scouring effect of icebergs that are increasingly breaking free from ice shelves as a result of global warming.

Flow Chart Unclear for Glacial Rivers

Glaciers in the high Himalayas and on the Tibetan Plateau are a vital source of water for millions of people in Asia, but scientists question what will happen to supplies if the rate of melting continues to rise due to climate-related factors.

Underworld Threat to Melting Icecap

Scientists using radar images of Greenland’s glaciers have discovered a spectacular underground landscape of “skyscraper” ice blocks formed by the melt-and-freeze cycle that is accelerating the reduction of the icecap.

Dark Shadows Fall on Melting Icecap

Dust blowing onto the Greenland icecap from warming areas of the Arctic is causing the ice to melt faster by reducing the whiteness that reflects light and keeps it cool.

How Nature Affects the Carbon Cycle

As global temperatures warm, scientists say that in both Australia and the Arctic natural processes are at work to help mitigate the increased heat.

Greenland Ice May Melt Even Faster

The vulnerability of Greenland’s glaciers to global warming is even greater than feared, according to radar and satellite data analysed by U.S. research scientists—and that’s bad news for rising sea levels.

No Way Back for West Antarctic Glaciers

Analysis of space satellite data reveals that the West Antarctic’s glaciers have passed the “point of no return” and will continue to melt inexorably as the Southern Hemisphere gets warmer.

Ocean Winds Put Heat on Australia

Winds of change caused by greenhouse gases in the Southern Ocean are keeping Antarctica cold but parching Australia by “stealing” more of its rainfall.

Himalayas to Be Wetter and Warmer Over Next Century

There have been dire warnings about melting glaciers in the Himalayas leading to falling flows in some of Asia’s major rivers. Now scientists are turning some of their original research on its head.

Greenland Faces ‘Modest’ but Risky Melt

Although scientists believe Greenland’s contribution to sea level rise may be less than had been thought, they say the impacts could still be serious.

Glaciers Are Melting Slowly but Surely

Most of the world’s glaciers are retreating more slowly than the few that are shrinking fast. But new research confirms that almost all of them are losing mass.
