Peter Hannam Heavy snow and black ice have triggered accidents and caused the closure of major routes in the Blue Mountains.
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...
Part of East Antarctica is more vulnerable than expected to a thaw that could trigger an unstoppable slide of ice into the ocean and raise world sea levels for thousands of years, a new study shows.
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...
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...
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...
From the Andes to the Alps and the Himalayas to Alaska, glaciers are melting as the planet warms.
Andrew Darby Three Australian Antarctic expeditioners injured in a helicopter crash have been evacuated from a remote ice shelf in a successful rescue mission.
A vast and previously unmapped gorge 800 metres deep has been found under ice in Greenland, comparable in size to parts of the Grand Canyon in the United States, scientists said.
Ice in Antarctica and Greenland is disappearing faster and may drive sea levels higher than predicted this century, according to leaked United Nations documents.
Arctic sea ice rebounded in 2013 from last year’s record melting season, though scientists warned that the long-term trend is for the ocean to become increasingly ice-free in the summer.
Katia Moskvitch The global energy markets, ever susceptible to influences, are balanced on a knife edge.
Peter Hannam Researchers hope the discovery of ancient Antarctic ice will give them access to crucial information about carbon dioxide levels during a period when ice ages were much more frequent.
National Geographic have produced an extraordinary series of images showing what the continents would look like if the ice caps were to disappear.
Peter Hannam It seems Charles Sturt, Thomas Mitchell and other early European explorers tramping the scorching deserts of Australia in search of an inland sea were a few thousand years too early.
US Defense Secretary Chuck Hagel announced the Pentagon's first Arctic strategy to guide changes in military planning as rapidly thawing ice reshapes global commerce and energy exploration, possibly...
Scientists have produced the first three dimensional map of the surface beneath Antarctic sea ice, helping them better understand the impact of climate change on Antarctica.
John Vidal The vast polar ice cap, which regulates the Earth’s temperature, has this year retreated further and faster than anyone expected.
Andrew Darby Satellite measurements have confirmed Antarctica is losing land-bound ice to climate change, ending years of uncertainty.
