Agree on your 2nd point, but believe the jury should still be out on the 1st. Its easy to say climate has been warming over the last several decades, but the published materials often lack sufficient analytical regard to measurement uncertainty. Engineers live and die by uncertainty analysis’, so why is that aspect so often neglected in the scientific research? The observed changes in temperature (very small, fractions of degrees) could easily fall within the measurement uncertainties of the instrument systems used for those measurements, so inconclusive. IMHO.

Climate change is real- is a cyclical natural event that goes from warmer to cooler to warmer- all by itself- it has happened all throughout history-
[[so inconclusive. IMHO.]]
Well we do have several indicators that show the mideieval times were much warmer than today- icecores records, periods where fauna did much better thanks to warmer lciamtes, periods where they died off due to colder temperatures , CO2 measurements in CO2 traps on earth etc-
I understand your fraction of a degree argument, however, I believe there are historical recrods of periods that were much warmer andm uch cooler- ie ice age etc-
