Atlantic Circulation Consistently Tied to Carbon Dioxide

by David Shultz 25 September 20192 July 2024

Past ocean surface conditions suggest that over the past 800,000 years, atmospheric carbon dioxide levels typically rose on millennial timescales when Atlantic overturning was weaker and vice versa.
