The Atlantic meridional overturning circulation (AMOC) is a large-scale overturning motion of the entire Atlantic, from the Southern Ocean to the high north. Graph by Ruijian Gou. The AMOC is a big deal for climate. It moves around 15 million cubic meters of water per second (i.e. 15 Sverdrup). For more on this see my Review Paper in Nature.

There is no doubt that we have changed Earth’s climate through our activities on a broad range of aspects that includes consequences for the atmosphere, the oceans, snow, ice, Earth’s fauna and ecosystems. The cause of our changing climate is the increase in atmospheric greenhouse gas concentrations that we have released into the air.
