Eirik Vinje Galaasen and colleagues presents a new study in Science that reveals gradual warming could trigger the ocean circulation to enter a more variable and chaotic state. 

How can the remains of ancient forests tell about a varying landscape? John Birks writes about his review paper on Quaternary botany.

While El Niños are normally associated with wet winters in Europe, Martin King was surprised to find the most extreme cases linked to drought.

Sediments are archives of past climates – provided you know when they were deposited. Sevasti Eleni Modestou uses lead to clock past events.

Inland Antarctic ice contains volumes of water that can raise global sea levels by several metres. A new study published in the journal Nature shows that glacier ice walls are vital for the climate, as they prevent rising ocean temperatures and melting glacier ice.

24 meter deep sediment core gives the image of a surprisingly rich flora.

“The warming threshold for significant Greenland Ice Sheet retreat could be less than 1°C above the present”

Autonomous ocean gliders on a year-round journey to unravel mysteries about the Lofoten Vortex

"Imagine turning into a liquid on a hot summer day", writes Willem Van der Bilt. To avoid that, some algae change their body fat. Fat in fossile algae reveal that Svalbard was seven degrees warmer 10,000 years ago.

Perhaps nowhere is the difference between cities and their surroundings greater than in the Arctic. Igor Ezau writes about a new study attempting to connect the environmental impact of Arctic cities with socio-economical decisions and policy governing city growth and decay.
