Looking at modeling simulations, researchers explore how various characteristics of the mid-latitude atmospheric circulation evolve over the 21st-century and find that changes are sector-dependent.

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.
A new study shows that the AMOC is more sensitive to warming, including changes in the atmospheric hydrological cycle, than Greenland Ice Sheet melting. However, Greenland Ice Sheet melt further increases the projected AMOC weakening.
A new study concludes that the likely source of changes in heat that caused the recent slowdown in the AMOC was from a decrease in the Agulhas Leakage and that changes in convection in the subpolar North Atlantic was an unlikely contributor.
A new paper shows that global mean surface temperature (GMST) is a measure of the Earth’s surface warming, not a measure of total accumulated heat energy in the Earth’s system. And the slowdown in GMST increase is most likely a redistribution of excess heat into and within the ocean.
New research looking at glacial-interglacial climate variability during the last 784,000 years finds that Earth's climate sensitivity is strongly dependent on the climate background state with significantly larger values attained during warm phases. Because the Earth is currently in a warm state, the associated increased climate sensitivity has to be taken into account for future warming projections.
New research finds that changes in the strength of the Agulhas Current, since the early 1990s, has not increased, despite expectations based on rapidly warming sea surface temperatures. Instead, its flow has broadened due to more meanders and eddies.
New research shows that even the longest and highest-quality tide gauge data may underestimate the amount of global average sea level rise that occurred during the 20th century, due to their limited location.
Robust surface ocean currents around Peninsular Florida, namely the Loop and the Florida Currents, are shown to affect the terrestrial wet season of Peninsular Florida. New research shows that differences in the ocean bathymetry (or topography) of two novel numerical climate model integrations can influence the ocean currents and their impact on regional climate.
There is very little doubt that human-driven climate warming will ultimately result in widespread ocean deoxygenation; however, substantial natural variation and sparse observational records make it difficult to determine when. New research suggests that human-driven changes in oxygen levels are evident in many oceanic regions now and will be widespread in the next 15-20 years.
