Ocean Circulation Plays an Important Role in Absorbing Carbon from the Atmosphere, NASA GSFC
June 29, 2017

NASA and MIT scientists found that gases are more easily absorbed over time than heat. As the Atlantic Meridional Overturning Circulation (AMOC) slows down, the ocean absorbs less of both atmospheric gases and heat, though its ability to absorb heat is more greatly reduced.

Precipitation differences between the positive and negative AMV
June 14, 2017

A multi-model simulation study shows that Atlantic Multidecadal Variability warming drives a modification of the Walker Circulation that creates precipitation anomalies over the whole tropical belt. 

SAMOC time series at four latitudes in the South Atlantic
May 8, 2017

A new study reconstructs a century-long South Atlantic Meridional Overturning Circulation index, from 1870 to present, finding it is highly correlated to the observational-based SAMOC time series and the Interdecadal Pacific Oscillation is the leading mode of variability.

sea surface height anomalies and upper-ocean temperature from the NOAA Kuroshio Extension Observatory
April 26, 2017

Approximately seven years of daily-averaged autonomous CO2 observations from NOAA’s Kuroshio Extension Observatory surface mooring were used to close the mixed-layer carbon budget, finding high rates of net community production during the spring bloom period.

Probability density functions of equilibrium climate sensitivity
April 24, 2017

Equilibrium climate sensitivity (ECS) — defined as the near-surface air temperature change that would eventually result from a doubling of atmospheric CO2 — is a key metric of climate change. New findings suggest that the value of ECS estimated from global energy budget constraints is actually in agreement with values derived from other methods and simulated by global climate models.
