High CO2 Levels Can Destabilize Marine Layer Clouds

I think that the subject line needs correction.

Mathematical modelling is a useful exercise, but it illustrates what could happen if the model happened to be a useful over-simplification of what might go on at that kind of atmospheric CO2 level.

Saying that it "can" happen isn't back up by any observation of the effect actually happening.

Even the Paleocene-Eocene Thermal Maximum doesn't seem to have got CO2 levels that high - current estimates don't put them much higher than now, with a sustained release of methane doing most of the warming

Of course methane is a more potent greenhouse gas and might have destablised the stratus clouds in the same way as lots of CO2.

Yes, it just might have. Is that your subject?

Oh dear, we're dead again.

John isn't great at processing this kind of data. The threat identified her e kicks in when atmospheric CO2 levels hit 1200 ppm. They are currently at

Fred, please quit polluting the group.

Sure, what we need is even more half-baked personal opinions.

Information that is reliable enough to get into peer-reviewed scientific journals is too tedious to feature here.
