What caused the change in salinity you ignorant lying piece of shit?Temperature dependent AMOC switch off based upon changes in salinity and density most certainly do. Then the NH freezes and albedo amplifies it. AMOC switches back on and it take a really long time to return to its pre-glacial trigger temperature where it happens all over again. And that's why we don't see logarithmic warming from a logarithmic GHG effect. Because it's not due to that at all. It was going to continue warming regardless because that's what it always does before it reverses itself. Been going on for millions of years.
