It’s the front line of climate change and could hold the key to predicting global sea level rise, but what goes on at the underwater face of Greenland’s glaciers is a mystery to science.

An international team including researchers from the University of Bern and the University of Geneva as well as the National Centre of Competence in Research (NCCR) PlanetS analyzed the atmosphere of one of the most extreme known planets in great detail. 

The Labrador Sea between Canada and Greenland is often referred to as a ‘lung of the deep ocean’ because it is one of only a handful of locations worldwide where oxygen from the atmosphere can enter the deepest layers of the ocean. 

New insight into how our early ancestors dealt with major shifts in climate is revealed in research by an international team, led by Professor Rick Schulting from Oxford University’s School of Archaeology.

To get through a long winter without food, hibernating animals — like the 13-lined ground squirrel — can slow their metabolism by as much as 99 percent, but they still need important nutrients like proteins to maintain muscles while they hibernate.

For many, an ideal forest is one that looks the same as it did before European colonizers arrived. 

The planet was different 700 million years ago. In the Cryogenian period, Earth featured a single supercontinent known as Rodinia, complex organisms had yet to explode on to the scene, and the globe was an ice-covered snowball.

If you had to guess which part of the world has the highest levels of atmospheric mercury pollution, you probably wouldn’t pick a patch of pristine Amazonian rainforest. Yet, that’s exactly where they are.

When rain falls, it picks up pollution from streets, farms and other manmade features as it winds toward the ocean.

Scientists repeatedly check the weather forecasts as they prepare aircraft for flight and perform last-minute checks on science instruments.
