The BBC reports (here and here) that research published in the journal Geophysical Research Letters has found no apparent long term slowing of the Gulf Stream. This may be one major dodged bullet; the Gulf Stream is essential to bringing heat north from the tropics and keeping Europe 4 - 6ᵒC warmer than it would otherwise be. The Gulf Stream is part of the Atlantic Meridional Overturning Circulation which itself is part of the global thermohaline system of currents.
On the other hand, and across Africa, the island known as New Moore Island to the Indians and South Talpatti Island to the Bangladeshis has now become nothing more than a hazard to navigation. The island itself has slipped beneath the waves of a rising ocean. The School of Oceanographic Studies (Calcutta) says that satellite imagery shows that the entire island is under water. So on the plus side of the global climate chaos ledger, rising sea levels have removed one source of international friction.
