Iron in the Earth's core weakens before melting

The iron in the Earth's inner core weakens dramatically before it melts, explaining the unusual properties that exist in the moon-sized solid centre of our planet that have, up until now, been difficult to understand.

Melting Arctic sea ice won't break records

The melting of sea ice in the Arctic is well on its way toward its annual "minimum," that time when the floating ice cap covers less of the Arctic Ocean than at any other period during the year.

Greenland ice melting hits record breaking pace

Melting over the Greenland ice sheet has loudly shattered the seasonal record on August 8 - a full four weeks before the official close of the summer melting season.

Greenland ice sheet won't disappear all at once

Greenland's ice sheet is rapidly melting, but an international team of scientists say predicting its complete disappearance would be premature.

Himalayan glaciers in better state than feared

Himalayan glaciers aren't shrinking as fast as thought - indeed, some are actually growing. 

Greenland ice sheet may melt completely

The Greenland ice sheet appears more vulnerable to global warming than previously thought, and could disappear altogether if global temperatures rise more than 1.6 degrees Celcius above pre-industrial levels.

Greenland lifts as ice sheet melts

Greenland's bedrock rose by more than three quarters of an inch in some places, following 2010's major loss of ice.

Earth's core is melting - and freezing

The inner core of the Earth appears to be simultaneously melting and freezing, because of heat circulation in the rocky mantle that covers it.

Mountain glaciers melting much faster than believed

Melting mountain glaciers are pushing up sea level rises faster than at any time in the last 350 years, say scientists - indeed, many are melting up to 100 times faster.

Climate change damaging ancient treasures

Climate change is destroying important archaeological remains that have been frozen for thousands of years, a study has shown.

Thawing permafrost to release vast quantities of carbon

Up to two-thirds of Earth's permafrost will probably disappear by 2200, say scientists, unleashing vast quantities of carbon into the atmosphere.

North Atlantic water warmest in 2,000 years

The water flowing from the North Atlantic into the Arctic Ocean is the warmest it's been in 2,000 years, say scientists.

Ice caps melting far slower than believed

The Greenland and West Antarctic ice caps are melting at half the expected rate, according to a joint US-Dutch team.
