A new study shows that the recent Arctic warming compares to abrupt climate change events in the distant past.

Whether Arctic warming influences mid-latitude weather is debated. A new study shows that the response to heating may depend on how high up the air is heated.

In the real reality, a pathway from sea ice to midlatitude weather has been observed. In most realities it would never have occurred.

Extreme stratospheric events impact weather at the surface. New research suggest the troposphere causes the events.

Near the end of the last ice age, the global sea level rose 12–14 meters in less than 350 years. New research traces almost half of the ice melt to Norway and the Barents Sea.

El Niño Southern Oscillation (ENSO) influences weather all over the globe. Clio Michel writes about new research on changes in the response if the Paris Agreement targets are met. 

The oceans twilight zone, the dimply lit part between the sunlit surface and the dark abyss is home to mysterious ways of life. In a recent Nature comment an international group of scientists propose that the exploration of this region should be pursued in a collective joined up way across the international scientific community.

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”

"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.

The freshening of the western North Atlantic from ice melt started as early as in the 1940's, new study indicates.

Kristian Vasskog's group found marine sediments higher on the island Karmøy than they thought the sea had reached. Southern parts of the island must have escaped the ice age much earlier than areas nearby.

In the last interglacial, the sea level rose to ten meters higher than today. For the first time, researchers have now traced the extra water to Antarctica.
