#thermohaline — Public Fediverse posts

Atlantic Meridional Overturning Circulation (#AMOC) is a massive #ocean_current in the #AtlanticOcean, driven by #temperature and #salinity changes (#thermohaline circulation). It influences global #weather significantly:

- Warms up #Arctic, East #Canada, #BritishIsles & #Nordic region
- Cools down #GulfofMexico, #Amazon & #Africa
- Drives #rains in all these regions
- Supports a huge #plankton #biomass, that:
- Supports higher #marine_life
- Acts as #CO2 #carbon_sink.

@rahmstorf This excludes #Greenland & the #Arctic Ocean, which have been warming at greater than #Earth average rates, as (e.g.) @ZLabe will confirm. The "cold blob" is the effect of #desalination, caused by melting of #polar #ice, resulting in slowing of #thermohaline circulation current. I'm educated to PhD level - I realise it's not easy to explain all this to the average layperson.

@micheltsamados
Nice visual presentation.
May I ask you something?
Would you know a complete map of the global currents and #thermohaline #conveyor belt?
I have watched quite a few talks on youtube, like from @rahmstorf and such, and have read yet more papers on all sorts of #climate-#ocean-related stuff. And I have seen just as many variations of such a global map, including a KMZ-file for #GoogleEarth - but none of them complete, as becomes clear when comparing one with another.
For me, to get a better grasp of all things, such a complete schematic would be very, very helpful, no, necessary.
🙏 💐

This one's been on my radar screen for 30+ years. Nice to see it getting a little attention. Consequences unknown but most likely to be BIG trouble. (Gifted)

ontem, mesmo no corre de viagem, consegui colaborar com essa matéria sobre o estudo que estimou o colapso da AMOC mais rápido do que o último relatório do IPCC

Circulação do oceano Atlântico Norte vai entrar em colapso até o fim do século por causa da mudança climática, projeta estudo

#Antarctic melt:

"The #meltwater from #glaciers makes the ocean surface less salty, and when it freezes, the waters below are less dense than normal, falling into the deep more slowly."

This slows down the #thermohaline #ocean currents.
