The length of a day has critical impacts on our technologies, navigation, and more.

This seemingly one-off heatwave may be a harbinger for the future under climate change.
Glaciers like Antarctica’s Byrd Glacier are showing cracks and movement.

A massive Antarctic ice shelf is showing signs of cracking and could trigger worldwide flooding.
A particularly stormy winter has pushed perennial sea ice into the Arctic melt zone.
Australia must treble its emissions reduction targets and reach net-zero emissions by 2035. Without this and other radical global action, the chance to hold warming to well below 2℃ will pass us by.
Cultures worldwide are awash with tales of great floods. What can they tell us about the reality of a wetter world?
A blue ice area, part of the West Antarctic Ice Sheet.

Our research shows the Antarctic could be closer to a tipping point than previously thought.
Field camp on the East Antarctic ice sheet.
Some 58 metres of sea level rise is locked up in Antartica’s ice sheets, and it’s melting faster than expected.
A small boat in the Illulissat Icefjord is dwarfed by the icebergs that have calved from the floating tongue of Greenland’s largest glacier, Jacobshavn Isbrae.
Sea levels could rise by two metres by 2100, sparking a refugee crisis unlike anything the world has ever seen.
The source of the Yamuna River, one of the major rivers draining the Himalayas.
A new report predicts that one-third of the ice in the Himalayas will melt, even if we contain global warming to 1.5C. So what does that mean for the flood-prone valleys below?
Melting Antarctic ice can trigger effects on the other side of the globe.
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.
Adélie penguin at the Mt Siple breeding colony, West Antarctica.
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.
Sea ice in the Arctic.
The link between melting sea ice and extreme weather has been known for a while, but now it’s happening further afield.
Some parts of Antarctica’s Totten Glacier are more stable than others.
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.
Rising sea levels are one of the clearest and most widespread manifestations of climate change.
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…
It may already be too late to stop Antarctic ice sliding into the ocean.
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…
The Thwaites Glacier is among several in West Antarctica that is already retreating.
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…
