Super, you wrote: Then, looking at the temperature data in figure 1, I would consider more carefully the atmosphere’s powerful tendency to revert to the long-term mean. The pattern then strongly suggests that we’re at a peak for the global temperature anomaly and that we’ll likely have some cooling.
The long term temperature is a cycle that goes above the mean and then below the mean. Temperature never returns to the long term mean, it just crosses the mean to the other bound. The Polar Ice Cycle does not seek a mean. It drives temperature from above the mean to below the mean. Then the Polar oceans freeze and turn off snowfall and the sun drives temperature from below the mean to above the mean.
Temperature varies in a cycle that goes warm, cold, warm, cold, warm, cold, etc. You can see this by just looking at actual official NOAA and NASA data. You can see this in the Ice Core Data.
I agree with you that we are near a peak, but this peak, like the Roman and Medieval Peaks, will last a few hundred years and then will drop below the mean to a minimum similar to the Little Ice Age.
Temperature does not try to maintain a mean. Earth Temperature cycles above and below the thermostat setting, just like in my house. My house warms until the Air Conditioner comes on and then cools until the Air Conditioner turns of. The Thermostat, the Set Point for Earth, is the temperature that Polar Sea Ice melts and freezes. Snowfall is turned on by thawed Polar Oceans and turned off by frozen Polar Oceans. The temperature is fixed by the temperature that oceans freeze and thaw. That does not change. The temperature record shows that the temperature is bounded close above and below this set point.
If you disagree, offer a different theory for why the temperature has been so well bounded for ten thousand years.
