Trees have died in Rocky Mountain National Park, Colo., as climate change has intensified bark beetle infestations and drought. Patrick Gonzalez

Human-caused climate change severely exposes the US national parks

As climate change alters temperature and precipitation patterns across the US, it is having especially severe impacts on national parks. These changes could happen faster than many plants and animals can adapt.

A bird’s eye view of New Zealand’s changing glaciers

Forty years of continuous end-of-summer snowline monitoring of New Zealand's glaciers brings the issue of human-induced climate change into tight focus.

Melting Arctic sends a message: Climate change is here in a big way

Climate change is transforming the Arctic, with impacts on the rest of the planet. A geographer explains why he once doubted that human actions were causing such shifts, and what changed his mind.

Don’t worry about the huge Antarctic iceberg – worry about the glaciers behind it

A huge iceberg is set to break free from Antarctica. While the iceberg isn't hugely concerning, it could herald the breakup of the entire Larsen C ice shelf, which could trigger more sea-level rise.
Glaciers have been a major contributor to sea-level rise. Knut Christianson

What does the science really say about sea-level rise?

Could sea levels really rise by several metres this century. Probably not, although this century's greenhouse emissions could potentially set the stage for large rises in centuries to come.

Explainer: why volcanoes erupt

What happens beneath the surface before a volcano erupts? Can we predict when one will blow? And how can typhoons and melting glaciers contribute to big eruptions?
The Totten Glacier, the largest in East Antarctica, has deep channels running beneath it that may allow relatively warm water into its belly. Tas van Ommen

Melting moments: a look under East Antarctica’s biggest glacier

Researchers in East Antarctica have surveyed an area the size of New South Wales to study the behaviour of the region's biggest glacier - and the secrets below the ice that could speed up its melting.

New Zealand’s Southern Alps have lost a third of their ice

A third of the permanent snow and ice of New Zealand’s Southern Alps has now disappeared, according to our new research based on National Institute of Water and Atmospheric Research aerial surveys. Since…
The Thwaites Glacier is among several in West Antarctica that is already retreating. NASA

We can now only watch as West Antarctica’s ice sheets collapse

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 glaciers deform the Earth’s mantle and crust

The significant retreat of elements of the West Antarctic ice sheet such as the Thwaites glacier recently reported in the journal Science suggests a possible sea level rise of 3 to 3.7m. This is a huge…
