OTOH, maybe that was a genuine example of climate warming, and the intervening cooler years have been random fluctuations, with the overall pattern now showing up with improved measurement methods.

I've said it before and I'll doubtless have to say it again. Things are never as simple as we'd like them to be. Perhaps all the gunfire during WWI affected the climate . . .

Yeah but, No but.
The gas make-up of the atmosphere at particular periods in history can be determined from Polar Ice cores. There has been no time since these began when CO2 levels were as high as they are now.

Middle Pliocene. CO2 level at its highest. Global temperature at its highest. Sea level 25 metres - not feet, metres - higher than now.

Is that 2 % compression at any particular temperature, or does it vary 'very' much ?

And I 'm also wondering , in the most commonly found large volumes of water - the Oceans - where the temperature is usually between , ( what?) 4 degrees and 8 degrees C. --- by what % expansion is there.
