There is constant climate change without any consideration of human caused CO2. Climate is not static and has so many different influencing factors that models have so far failed. Ice columns drilled in Greenland give us a record of constant climate change over hundreds of thousands years.
Evolution is a fact, deal with it.
Evolution is theory, and is fairly robust, but very difficult to test and observe. There is no “settled science”in Science. It is all open to refinement, and incorporation of new observations. Only a non-scientist would make a claim that “this is Science fact” or “the Science is settled.”
Allele frequency change is not speciation (therefore not evolution), nor is it introduction of new genes into the species gene pool.
This selection pressure is all within the steady species state in Gould’s punctuated equilibrium model of evolution.
Amateurs chanting “evolution” don’t actually advance Science.
(On natural climate change, I’m fairly sure we agree completely.)
