A study presented in Nature Geoscience suggests that changes in solar intensity and volcanic eruptions act as a metronome for temperature variations in the North Atlantic climate.

An abrupt and persistent strengthening of the ocean currents forming the Atlantic subpolar gyre could have resulted from a large freshwater flooding event 8,200 years ago. New climate model simulations resolve the apparent contradiction of increased freshwater inflow and enhanced deep water formation in the North Atlantic.

New analysis of climate and oceanographic variability of the last 12,000 years reveals that the SW Barents Sea is characterized by large-scale natural variability.

A new database of marine carbon observations covering the Atlantic Ocean was released in 2009. This will be an invaluable resource for future carbon cycle science.

Human induced climate change will probably reduce nature’s ability to absorb carbon dioxide, particularly in the North Atlantic and Northern Europe. An implication is that more carbon will remain in the atmosphere, and thereby intensify future climate change.

Recent climate warming is most pronounced in the Arctic, where sea ice cover might be the canary in the coal mine for future changes.

New observations reveal spectacular mixing rates and turbulence, and new insights into circulation structure and dynamics in deep waters spilling down to the North Atlantic.

As warm Atlantic Water flows north- and eastward along the coast of Svalbard it experiences strong cooling by heat loss to the atmosphere and to melting of ice. Direct measurements show the importance of strong tidal currents and shallow topography for the efficiency of this cooling.

A new version of the Bergen Climate Model is able to simulate important features of the observed climate over the last 150 years.

Stronger ocean currents have transported more heat to the Barents Sea over the last years. Despite this extra heat, the mean temperature has only increased modestly. The reason is a stronger heat loss caused by more open water during wintertime.
