Emperor Penguins thrive in harsh conditions, but a new study shows that their fate depends on human action to slow global warming and associated loss of sea ice.

Antarctica is no longer the sleeping giant of sea level rise. New research delved into the past and found when the Earth warms, its ice sheets can melt extremely quickly.
New research confirms that what the world pumps into the atmosphere today has grave long-term consequences. Governments - especially Australia's - must urgently ramp up efforts to reduce emissions.
Scientists are uncovering the secrets of a giant undersea rock shelf, parts of which lie four kilometres below the ocean's surface.
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.
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.
