The crew of scientists prepare to put the drill stem into the Greenland ice sheet to probe water flows about a half of a mile below. Joel Harper

Scientist at work: Tracking melt water under the Greenland ice sheet

A glaciologist develops a lightweight method for probing the depths of Greenland's ice sheet to answer a crucial question: How fast is it melting?

Ancient life in Greenland and the search for life on Mars

Scientists say they've found fossils showing life existed on Earth 3.7 billion years ago. How good is the evidence? And what does it mean for the search for life elsewhere in our solar system?
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.

Declining winter sea ice near Greenland spells cooler climate for Europe

Loss of sea ice near Greenland and Iceland portend a colder future for Europe.

Why ice sheets will keep melting for centuries to come

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…

Greenland ice sheet is melting at an accelerating rate

Warming in the Arctic has now reached the northernmost sections of the Greenland ice sheet. After a long period of stability (more than 25 years), we have found in a new study of the region that the northeast…

Chasing Ice bewitches eyes but won’t change minds

Science seems to be failing to change the minds of those who are sceptical about the reality of anthropogenic climate change. Chasing Ice - a film by Jeff Orlowski, playing in Australia currently - tries…

Greenland ice loss is accelerating

Global warming has caused nearly 200 billion tons of Greenland’s mass to disappear annually in the last decade but its icy…

Humans did affect the atmosphere - even before industrialisation

The past is the key to the future. When snow falls on polar ice sheets, in Greenland and Antarctica for example, air is trapped between the snowflakes. Year after year, the snow compacts under its own…
