New research shows that warming by more than 2°C could be a tipping point for Antarctica’s ice sheets, resulting in widespread meltdown and changes to the world’s shorelines for centuries to come.

These lakes could threaten the future stability of parts of the Antarctic ice sheet.
The IPCC report says extreme sea level events that used to hit once a century will occur once a year in many places by 2050. This situation is inevitable, even if emissions are dramatically curbed.
Each spring, winds circling the South Pole weaken. If they weaken enough, they can actually reverse – causing rapid warming.
‘Dual use’ technology – technology used for both peaceful and military purposes – is allowed in Antarctica, according to the treaty.
New research shows that ocean and air temperatures both contributed to the melting of Antarctica’s Ross Ice Shelf in the past, but melting from below by a warming ocean became more important over time.
Cooperation or theft? New observations show wild leopard seals sharing food when targeting king penguins in Antarctica.
Sending autonomous vehicles to the Southern Ocean can be fraught with anxiety, especially if one of them doesn’t make radio contact when it’s supposed to.
Some 58 metres of sea level rise is locked up in Antartica’s ice sheets, and it’s melting faster than expected.
Parts of Antarctica’s largest ice shelf are melting ten times faster than the rest of the shelf, and solar heated waters below the ice are to blame.
Emperor penguins have a few hidden tricks to stay warm, like blood vessels in the nose arranged so they can regain most of the heat that would be lost by breathing.
Sea levels could rise by two metres by 2100, sparking a refugee crisis unlike anything the world has ever seen.
A paleooceanographer describes her ninth sea expedition, this time retrieving cylindrical ‘cores’ of the sediment and rock that’s as much as two miles down at the ocean floor.
Buildings and human disturbance in Antartica is clustered in an ice-free zone that is essential to most of the continent’s biodiversity.
Climate scientist predict that the combined effect of ice loss in Greenland and Antarctica will be more extreme weather, with impacts on agriculture, infrastructure and human life itself.
Antarctic sea ice cover fell to an all-time low recently and hasn’t yet recovered. Why? The initial answers could lie in an unlikely place – the tropics.
The Antarctic Circumpolar Current provides a barrier to heat that keeps warm subtropical waters away from Antarctica. Yet, there are a few places where the heat gets through.
Isolation at work can be unhealthy. But it can also be a good thing – as this researcher found out when he walked solo from Melbourne to Sydney.
More than two-thirds of Earth’s remaining wilderness is in the hands of just five countries, according to a new global map. A concerted conservation effort is needed to save our last wild places.
There are some limits on what countries can do in the Antarctic, but not when it comes to science.
