Privileged Planet: Atlantic circulation is lessening (Introduction)

It is diminishing the Atlantic Gulf Stream:

"The Atlantic Ocean circulation that underpins the Gulf Stream, the weather system that brings warm and mild weather to Europe, is at its weakest in more than a millennium, and climate breakdown is the probable cause, according to new data.

"Further weakening of the Atlantic Meridional Overturning Circulation (AMOC) could result in more storms battering the UK, more intense winters and an increase in damaging heatwaves and droughts across Europe.

"Scientists predict that the AMOC will weaken further if global heating continues, and could reduce by about 34% to 45% by the end of this century, which could bring us close to a “tipping point” at which the system could become irrevocably unstable. A weakened Gulf Stream would also raise sea levels on the Atlantic coast of the US, with potentially disastrous consequences.

"Dr Levke Caesar, of Maynooth University in Ireland, and the lead author of the paper, said sea level rises on the east coast of the US were another potential consequence. “The northward surface flow of the AMOC leads to a deflection of water masses to the right, away from the US east coast. This is due to Earth’s rotation that diverts moving objects such as currents to the right in the northern hemisphere and to the left in the southern hemisphere,” she said. “As the current slows down, this effect weakens and more water can pile up at the US east coast, leading to an enhanced sea level rise.'”

Comment: The Guardian is a total climate alarmist paper. I will search for skeptical comment for balance.
