Canie, what you just posted is not what I am talking about. What I am talking about is simple. It is a simple fact of physics that CO2 is a greenhouse gas that helps keep the earth warmer than it would be otherwise. It is a simple fact that CO2 has gone up from 280 ppm pre-industrial to 380 ppm....most of that increase has been measured with instruments since about 1950. What is not so simple is where that leads. One thing that seems straightforward and logical is that the North Atlantic deep water forms somewhere in the north Atlantic (D'uuh)...don't have a map...think it is between Norway and Iceland or a bit north of there. If the surface water there becomes warmer or less salty or both, it won't sink. That will disrupt the bottom currents. You can't sink water without other water upwelling. So, if you don't sink water, something else has to change. Most of the ocean productivity in deep ocean water is in areas of upwelling (Equator, circum Antarctic, California...).

I finally understood why the Gulf Stream might shut off or slow way down a week or 2 ago. I took a grad course in Physical Oceanography at the Grad Scool of Oceanography at University of Rhode Island back in 1981 (as an undergrad). The Gulf stream is driven by a surface elevation change across it of a meter or 2: the sea surface at the warm water to the south is higher. It wants to flow downhill but the coriolis effect/Ekman transport deflects it to the right and it flows parallel to the gradient (geostrophic current...air currents do this also). Climate models have long prdicted that high latitudes will warm more than low latitudes. If this happens, and the waters north of the Gulf Stream warm, the sea surface elevation gradient will decrease. So, what drives the Gulf Stream will decrease. If the Gulf Stream slows, the warming in Northern Europe will not be as much as it might have been otherwise. But, might not be a good thing that all that heat in the Gulf of Mexico and SE coastal water (Florida to North Carolina) not be transported NE....
