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?
