Geology

The Earth has lost a quarter of its water

In its early history, the Earth's oceans contained significantly more water than they do today. A new study indicates that hydrogen from split water molecules has escaped into space.

Trees survived the Ice Age in Scandinavia

The genetic structure of ancient trees suggests that we may have to rethink how life reacts to climate change.

How to see through rock

It’s costly to drill deep into the ground for thermal energy. So you may want to know what’s going on down there. Mathematicians can help.

Finland, the new lithium powerhouse?

Lithium is in high demand all over the world. Now mining for the valuable metal is about to start in Finland.

The basement solves an oxygen puzzle

The Earth’s atmosphere did not become rich in oxygen in a single event, but through a series of episodes spread over hundreds of millions of years.

Historically large glacier losses in 2000s

The sharp reduction of a Greenlandic glacier in the 2000s was historically large and was caused by short-term climate changes, new research reveals. It also shows the first definite link between climate change and glacial melting.

Dilemmas of mining

The mining industry wants to extract the valuable metals and minerals that can be found in Norwegian mountains, but what to do about the huge amount of waste?

Geology behind mass extermination

New study challenges the established view that a sudden climate change caused a sharp reduction in the number of animal species.

Air-traffic shutdown justified

Last year’s closing of flight zones due to the eruption of Icelandic volcano Eyjafjallajökull was justified, considering the potential damage from the ash, a new study concludes.

Warm sea currents caused the melting of Greenland’s ice

It was the sea temperature, rather than the air temperature, that determined how fast Greenland’s ice cap melted at the end of the last ice age. This discovery is important for today's research into ice melt
