One more time for the intentionally ignorant deceiver, intellectually dishonest jerm......fanatical partisan extrodinaire.
He used the term wrongly. I've already explained why several times.
But once again.
A thermostat is a negative feedback mechanism.
That is, as it gets warmer the t'stat reduces the heat input. When it gets cooler it increases heat input.
CO2 in the thermosphere does not act this way. It acts like a zero feedback device like a blanket.
And, once again, who cares about the thermosphere? Good job of evasion and conflation there. Right from the playbook. If I didn't know better I would think you are working for conservative "think" tank.
This is what NASA says.....
In its recently released Fourth Assessment Report, the Intergovernmental Panel on Climate Change, a group of 1,300 independent scientific experts from countries all over the world under the auspices of the United Nations, concluded there's a more than 90 percent probability that human activities over the past 250 years have warmed our planet.
The industrial activities that our modern civilization depends upon have raised atmospheric carbon dioxide levels from 280 parts per million to 379 parts per million in the last 150 years. The panel also concluded there's a better than 90 percent probability that human-produced greenhouse gases such as carbon dioxide, methane and nitrous oxide have caused much of the observed increase in Earth's temperatures over the past 50 years.
