Except that there is no positive correlation between climate change and increased carbon dioxide in the atmosphere.

According to a graph on NASA, between 1880 and 1938, there was an obvious warming trend that was concurrent with an atmospheric CO2 increase of +20 ppmv.

Between 1938 and 2004, there was a cooling and recovery and there has been no net warming since 1938. This cooling was concurrent with an increase in atmospheric CO2 of +60 ppmv.

The temp increase over the last 100 years is .6 degrees.

Pre-industrial CO2 levels made up .028% of all components in the atmosphere.

Present day CO2 levels constitute .0384% of the atmosphere. CO2 accounts for 72% of greenhouse gases but even if it were to double, it would still make up less than .01% of our atmosphere. Water vapor makes up far more of our atmosphere than CO2 does and is far more efficient at absorbing and trapping heat from the sun.

Climate change covers everything; from -100% to 100%. Just one of those convenient terms that they like to use (instead of Global Warming which only covers positive temp changes). That’s all my post was meant to illustrate. :)

Water vapor makes up far more of our atmosphere than CO2 does and is far more efficient at absorbing and trapping heat from the sun.

While accurate, this is irrelevant. We're not adding water to the environment. In fact, we have no way to add water. There's already just about more water than anything else.

We are adding carbon. Doesn't mean the warmists are right, but we should try to be scientifically accurate.

"CO2 accounts for 72% of greenhouse gases"

Only if one excludes water vapor.

Yes, there are other factors. Clean Air regulations removed particulates from the atmosphere that might have counteracted CO2 and caused a cooling trend.

I tend to agree with Lord Monckton, that the sensitivity is where there's a problem. Likely, CO2 does have a minor effect, but not to the extent we are led to believe.
