The total collapse of glaciers in West Antarctica is 'inevitable', writes Tim Radford, as the southern hemisphere gets warmer and glaciers are undermined by seawater. The news has emerged from a new analysis of satellite data.

Greenland's glaciers are more vulnerable to global warming than had previously been feared, reports Tim Radford, as ice bodies are undercut by seawater. The threat of rapidly rising sea levels just went up yet another notch.

As Arctic Peoples at COP21 in Paris appeal for unity to halt global warming, writes Tim Radford, scientists report that Greenland's glaciers are now melting at a speed not seen since the last Ice Age almost 10,000 years ago.

As temperatures rise in the Southern Ocean, warmer currents are eroding the Antarctic ice sheet from below, writes Tim Radford - causing the melting rate to treble in two decades to 83 billion tonnes a year.

Scientists warn that burning up the planet's remaining fossil fuel would cause all Antarctic ice to melt and lead to 58m of sea level rise over 10,000 years, writes Tim Radford. But devastating impacts would strike much sooner, with oceans rising by 3m a century for the next millennium.

A dusty film of pollution is muting the reflective whiteness of Greenland's pristine icecap and making it vulnerable to accelerated melting rates, writes Tim Radford. And as warming continues, the declining reflectivity of the ice is accelerating the process.
… the ice meets the bedrock ? And why have the glaciers started to accelerate on their …
Something scary is lurking in the melting Arctic permafrost, write Tim Radford & Oliver Tickell: 1,700 Gt of carbon. That's 53 years worth of current emissions, and if we let it melt the impact would cost the world $43 tn. Or act now, and we could preserve the Arctic ice for a seventh as much.

To keep the world's coral reefs alive we may have to cool tropical seas by blocking the sun's rays above them, writes Tim Radford. Even if the world reduces carbon emissions, warming already 'in the pipeline' could kill 90% of the world's coral by 2050 unless we act.

Religious values are often consistent with conservation efforts. So it’s not surprising that a variety of religious organisations and conservationists are working together to help mitigate the devastating effects of global climate change, writes CURTIS ABRAHAM

As much of California and the western US endures a severe drought, the city of Los Angeles is at increasing risk from rising sea levels. Tim Radford reports on the risks to the 12,000 square mile conurbation.

Rising greenhouse gas levels are causing stronger winds over the Southern Ocean. It's good news for Antarctica, writes Tim Radford, as the circumpolar winds are keeping its ice caps cold. But Australia is getting hotter and drier - and its problems will only increase.
… hard to measure on the continent itself, glaciers have been in retreat and ice shelves …
New research warns that rising temperatures will reduce the mountain snow in 97 major river basins worldwide, writes Tim Radford - cutting summer water supply to 2 billion people in lowland areas who depend on the meltwaters.
