Climate crisis: Scientists spot warning signs of Gulf Stream collapse
A shutdown would have devastating global impacts and must not be allowed to happen, researchers say
"Climate scientists have detected warning signs of the collapse of the Gulf Stream, one of the planet’s main potential tipping points.
The research found “an almost complete loss of stability over the last century” of the currents that researchers call the Atlantic meridional overturning circulation (AMOC). The currents are already at their slowest point in at least 1,600 years, but the new analysis shows they may be nearing a shutdown.
Such an event would have catastrophic consequences around the world, severely disrupting the rains that billions of people depend on for food in India, South America and West Africa; increasing storms and lowering temperatures in Europe; and pushing up the sea level off eastern North America. It would also further endanger the Amazon rainforest and Antarctic ice sheets."

*The actual quote from the Scottish play is "Lay on, Macduff", Act 5, Scene 7.
Macbeth I will not yield To kiss the ground before young Malcolm's feet, And to be baited with the rabble's curse. Though Birnam wood be come to Dunsinane, And thou, opposed, being of no woman born, Yet I will try the last. Before my body I throw my warlike shield. Lay on, Macduff, And damned be him that first cries, 'Hold, enough.'
