Bad news about rising sea levels as quickening Antarctic winds lead to faster ice melt

Destructive winds: Impact had previously not been taken into consideration.

Peter Hannam Global sea levels may rise much faster than currently predicted because climate models have failed to account for the disruptive effects of strengthening westerly winds, Australian-led research has...

Tourism threatened by climate change as ski slopes thaw, seas rise

Mt Buller, via snow cam, June 18.

Climate change is a growing threat to tourism, from thawing ski resorts to coral reefs hit by warmer seas, and the industry itself should do more to curb its soaring greenhouse gas emissions, a study...

Global carbon dioxide levels exceeded historic threshold throughout April

Globe

The amount of carbon dioxide in the atmosphere averaged more than 400 parts per million throughout April, the first time the planet's monthly average has surpassed that threshold.

West Antarctic ice sheet melt 'unstoppable', pushing sea levels higher, scientists say

antarctica

The collapse of large parts of the ice sheet in West Antarctica appears to have begun and is almost certainly unstoppable, with global warming accelerating the pace of the melting, two groups of...

Sea levels to rise as West Antarctic ice sheet melts

Warming waters are bad news for major Antarctic ice sheets.

Peter Hannam A collapse of the giant West Antarctic ice sheet appears ''inevitable'', with only the timing of the melting and resulting sea-level rise of at least three metres uncertain, according to US...

Forest fires and global warming caused an extreme melt of Greenland's ice in 2012, according to a study on Monday that said such thaws may happen almost yearly by 2100, threatening the survival of...

Global warming raises risks of more deadly Everest-like avalanches, researchers say

Everest

Mountaineering tourism in Nepal faces a threat from global warming as melting glaciers feed the risk of more deadly disasters such as the avalanche on Mount Everest that killed 16 people last month,...

Fire and ice: Melting Antarctic poses risk of volcanic activity, study shows

Antarctic study

Peter Hannam New research on the effects of ice sheet melt in the Antarctic shows climate change is deforming the Earth's crust, potentially prompting volcanic activity that could cause global sea-levels to rise...

Melting of the world's ice anything but glacial

From the Andes to the Alps and the Himalayas to Alaska, glaciers are melting as the planet warms.

Alex Morales China is working on how to cap its greenhouse gas for the first time, an effort that would spur the worldwide effort hold back climate change.

Global warming melts edge of Greenland icesheet

Greenland's ice sheet is melting.

The last edge of the Greenland ice sheet that had resisted global warming has now become unstable, adding billions of tonnes of meltwater to rising seas, scientists say.

Sea-level rise to accelerate as La Nina effect ebbs, study finds

Heavy rains from the Amazon to Australia have curbed sea level rise so far this century by shifting water from the oceans to land, according to a study that rejects theories that the slowdown is tied...
