The climate secrets contained in an ancient tree that lived through abrupt global change reveal how Antarctica can trigger rapid warming in the north by dumping cold water into the Southern Ocean.

Climate change is set to expand Antarctica’s ice-free area, potentially helping native species to flourish but also paving the way for invasive species to gain a foothold.
The link between melting sea ice and extreme weather has been known for a while, but now it’s happening further afield.
New mapping shows how Antarctica’s huge Totten Glacier has retreated far inland, raising sea levels by more than a metre. Rising temperatures could trigger it to do so again.
Since 1993, satellites have been used as well as tidal gauges to monitor sea level. A new calibration of this satellite record now shows that the rise in sea level is gathering pace.
For several years now climatologists have puzzled over an apparent conundrum: why is Antarctic sea ice continuing to expand, albeit at the relatively slow rate of about one to two percent per decade, while…
Ice sheets respond slowly to changes in climate, because they are so massive that they themselves dominate the climate conditions over and around them. But once they start flowing faster towards the shore…
There is an enormous mass of ice beneath the Greenland ice sheet, which has melted and refrozen making the sheet ragged and…
Antarctic climate science is having a moment – a worrying moment. Three new studies have all concluded that the West Antarctic Ice Sheet has begun to collapse. This collapse will impact humanity for generations…
Melting permafrost in places like Sweden could result in even higher levels of carbon emissions than predicted, accelerating…
Scientists have discovered the loud sound of sizzling glacier ice melting into the sea which may hold the key for monitoring…
Scientists are able to more accurately predict sea level rise thanks to new research into how glaciers respond to climate…
It is no secret that climate change is transforming the polar regions. Retreating glaciers, melting ice-caps and changing sea ice patterns are frequently reported in both the Arctic and Antarctic, and…
Most people saw the warm dry weather from June to September as a welcome, but freak, occurrence. Because, as anyone who invested in floaty dresses, barbecues or expensive sunglasses in previous years will…
Recently NASA reported that this year’s maximum wintertime extent of Antarctic sea ice was the largest on record, even greater than the previous year’s record. This is understandably at odds with the public’s…
The general thrust of the IPCC’s Fifth Assessment Report - released on Friday – can be summarised as: “there is now more evidence that climate change is occurring”. Antarctica and the Southern Ocean are…
Antarctic ice shelves are losing ice by melting from their undersides, as well as by calving icebergs. A study compiled by…
A previously unknown canyon has been discovered in Greenland, hidden beneath the ice. It is at least 750 kilometres long. To put that in perspective, imagine a ten kilometre wide gorge, up to 800 metres…
The melting of glaciers accounts for one third of observed sea level rise, according to new research published in Science…
Two papers released last week in the journal Nature Geoscience provide evidence that warming and melt in West Antarctica are occurring at levels that are highly unusual compared to natural variability…
