The AMOC is slowing, it’s stable, it’s slowing, no, yes, …

Real Climate

The background to this discussion is familiar to our regular readers (else just enter ‘AMOC’ in the RealClimate search field): proper measurements of the AMOC flow are only available since 2004 in the RAPID project , thus for earlier times we need to use indirect clues. In the real ocean that is not an observed quantity.

Twenty years of blogging in hindsight

Real Climate

It’s 20 years since we started blogging on climate here on RealClimate (December 10, 2004). There is one graph that perhaps tells the story of what has happened since 2004, and it’s the Keeling curve shown in the figure below. Another thing I didn’t anticipate in 2004 was efforts such as the World Weather Attribution (WWA).

What is happening in the Atlantic Ocean to the AMOC?

Real Climate

The Atlantic meridional overturning circulation (AMOC) is a large-scale overturning motion of the entire Atlantic, from the Southern Ocean to the high north. We don’t have direct measurements over such a long time (only since 2004 from the RAPID project ), but various indirect indications. Graph by Ruijian Gou. 15 Sverdrup).

New Satellite Will See Water’s Big Picture

Circle of Blue

Part of the Surface Water and Ocean Topography (SWOT) satellite’s science instrument payload sits in a clean room at NASA’s Jet Propulsion Laboratory during assembly. SWOT, which will measure ocean currents in addition to freshwater flows, will be the latest entrant into this hall of remote sensing champions.

The AMOC: tipping this century, or not?

Real Climate

We have direct AMOC measurements only since 2004, a time span too short for this type of study. Not in summer when the ocean is covered by a shallow surface mixed layer heated by the sun and highly dependent on weather conditions.) I’ve seen two main arguments there. Do the data used really describe changes in AMOC? It looks like this.

The Rise and Fall of the “Atlantic Multidecadal Oscillation”

Real Climate

Two decades ago, in an interview with science journalist Richard Kerr for the journal Science, I coined the term the “Atlantic Multidecadal Oscillation” (AMO) to describe an internal oscillation in the climate system resulting from interactions between North Atlantic ocean currents and wind patterns. Shindell et al, 2004 ).

Old habits

Real Climate

Media awareness about global warming and climate change has grown fairly steadily since 2004. But because land isn’t quite as dark as the surface of the ocean, it doesn’t cause as much additional heating. My impression is that journalists today tend to possess a higher climate literacy than before. 2659-2673, 2011. Aue, and A.
