I don’t buy it at all. We’re no where near the highs of the last three inter-glacial cycles in spite of an approximate 300% increase in global CO2 since industrialization began.
There’s also the problem of CO2 increasing following heating due to the increase in biological activity and out-gassing of the oceans as carbonates break down.
The most basic element of proving a theory is being able to show it repeatedly is true under controlled conditions in the lab and AGW theory simply cannot be.
You can raise the levels of CO2 to such a level that no animal live other than anaerobic bacteria can survive in a closed environment without raising the temperature by more than a couple of degrees F unless you pressurize the container.
Even if it could be proven that our contribution has raised the temp’s by a degree or two that just means we have created more arable land and more available water.
Glaciation ties up vast amounts of fresh water and creates massive droughts as a direct result with lower rainfall as a secondary result of the lower temps.
They wouldn’t have to keep tossing out temp data that doesn’t support the theory and cook the rest of it to fit the predetermined outcome if the theory held any actual basis in fact.
What also gets completely ignored is the fact that there was no temperature data for more than 90% of the earth’s surface prior to the 40’s and none at all prior to about 300 years ago when accurate thermometers first became available ans started getting distributed widely to the major cities.
Everything else prior is flat made up or taken from proxy data.
