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).

We have direct AMOC measurements only since 2004, a time span too short for this type of study. If the AMOC weakens, this region will cool. And in fact it is cooling – it’s the only region on Earth which has cooled since preindustrial times. I’ve seen two main arguments there. From Rahmstorf and Ganopolski 1999.

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. Background.

Well, back in 1993 (before the more comprehensive critiques had been published), Hoyt and Schatten put together a long-term estimate of solar activity that relied on the SCL, based on the idea from FCL91 and scaled to a finding about cycling and non-cycling stars that turned out to be wrong too (Wright, 2004). 1273-1278, 2004.

This would have a cooling effect on Atlantic SST, as well as a stabilizing effect on the regional atmosphere ( Dunion and Velden 2004 ), and would be expected to reduce tropical storm formation frequency for some (possibly prolonged) period. 353-366, 2004. 2016 ), could increase again in concentration.

This volume has become one of my favorites among the many I have read on climate and sustainability issues since I started back to 2004 (check the list there ). Bringing back Nature from the brink of collapse can be done by implementing regenerative solutions to our land and oceans. It can bounce back if given the opportunity.

And their appearance — red eyes and orange and black bodies – are so cool, and make some of us think about another season — Halloween! For example, in the Philadelphia region we have three brood cycles of the 17-year cicada: Brood X – this year’s brood in 2021 (last was 2004). Entomologists like me are so excited to see these insects.
