Glaciologists are discovering new ways surface meltwater alters the internal structure of ice sheets, and raising an alarm that sea level rise could be much more abrupt than current models forecast.

Icebergs don’t just pose a risk to ships – they have a profound impact on the natural world and human societies.

To fully understand the extent of climate-related dangers the Arctic – and our planet – is facing, we must focus on organisms too small to be seen with the naked eye.

A new geophysical analysis helps fill gaps in an archeological puzzle: why Norse vanished in the 15th century.

Glaciers in Greenland may be melting as much as 100 times as fast as than previously thought, researchers report.

The annual report is also a reminder that what happens in the Arctic affects the rest of the world.

The annual report describes the changes underway and the impact they’re having on people and wildlife. It’s also reminder that what happens in the Arctic affects the rest of the world.

A recent paper suggested damaging climate tipping points could be closer than first thought.

Harvard researchers take sea level fingerprints from theory to fact.
