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.[2/7]

Blue crabs spotted in James River in Richmond, Virginia amid drought
Reduced freshwater runoff into the Chesapeake Bay has allowed saltier water from the Bay to push farther upstream, increasing salinity levels in the James River and making it easier for species such as blue crabs to travel inland as far as the I-95 bridge in Richmond.

Climate models show considerable discrepancies in their future projections around the Atlantic, mainly due to uncertainties in the fate of the Atlantic Meridional Overturning Circulation (#AMOC).
#Climate models have previously suggested a reduction in AMOC strength of 32±37% by 2100.
But a closer examination, however, gives an estimate of the AMOC slowdown of 51±8%.
This refinement mainly results from correcting a bias in South Atlantic surface #salinity, consistent with recent studies emphasizing its role in the proximity to an AMOC tipping point.
This more substantial AMOC weakening has key implications for future #adaptation strategies.

Growing Salty
Ngangla Ringco sits atop the Tibetan Plateau, breaking up the barren landscape with eye-catching teal and blue. This saline lake sits at an altitude of 4,700 meters, fed by rainfall, Himalayan runoff, and melting glaciers and permafrost. The lake, like many inland bodies of salt water, has no outflow. Instead, water evaporates from the lake, leaving behind any salts that were dissolved in it. Over time, those left-behind salts build up and make the lake ever saltier.

Rising surface salinity and declining sea ice - a new Southern Ocean state revealed by satellites: https://www.pnas.org/doi/10.1073/pnas.2500440122 -> "Using satellite observations, we reveal a marked increase in surface #salinity across the circumpolar Southern Ocean since 2015. This shift has weakened upper-ocean stratification, coinciding with a dramatic decline in Antarctic sea ice coverage. Additionally, rising salinity facilitated the reemergence of the Maud Rise polynya in the Weddell Sea, a phenomenon last observed in the mid-1970s.

@yappari
The Gulf of Maine was special in that the cold-salty Labrador Current dominated there. Now, due to climate change, the Labrador Current gets fresher and weaker from Arctic meltwater. And the warm salty Gulf Stream takes over in the Gulf of Maine, letting it warm three times faster than the global oceans. Says so here in a new, beautiful reporting on how this affects coastal and sea life in the GOM: https://www.nationalgeographic.com/environment/article/gulf-of-maine-climate-change-photographerIf indeed the GOM deep #ocean temperature and #salinity have decreased in the past 6 months, (not mentioned in the NatGeo article but in the article quoted in #1) it would mean that the contribution by the Gulf Stream flowing in from the South got weaker and the Labrador Current was able to resume its dominion temporarily.
