Professor Christy doesn’t know what he is talking about...there is NO, NONE, ZERO, association with CO2 and “climate change” and human activity is not involved at all...there is NO proof that CO2 has anything to do with global climate cycles.

“Professor Christy doesn’t know what he is talking about...there is NO, NONE, ZERO, association with CO2 and “climate change” and human activity is not involved at all...there is NO proof that CO2 has anything to do with global climate cycles.”

those are two very different ststements. The second is sort-of true, ie that there is no ‘proof’ that CO2 changes in the range that the Earth is currently witnessing is affecting climate. There is some evidence of correlation but it’s likely not statistically significant once you take all of the ‘climate science’ fudge factors out of the studies. For an excellent source on that issue see climateaudit.org.

However it is not true to say “there is no association with CO2 and climate change and human activity is not involved at all” because that has not been proven, just as the claim that climate change is caused by human activity is also not proven.

Actually CO2 is strongly correlated with climate. But the warmists are looking at atmospheric CO2 rather than oceanic Co2. There is vastly more CO2 in the oceans than in the atmosphere. However, CO2 concentration follows temperature change. It is a response to climate change it does not cause it. Atmospheric CO2 changes are mostly due to changes in the amount of CO2 held in solution in the oceans. Cool oceans mean more CO2 in solution. Warm oceans mean less CO2 in solution. Think of the pressure of a warm (unopened) soda bottle vs. a cold (unopened) soda bottle -or beer.

When water warms it releases CO2 held in solution. When it cools it absorbs more CO2.

CO2 does not cause climate change.
