1. Global Warmists should be able to say conclusively what temperature is optimum.
2. Global Warmists’ models that show rampant global warming by such-and-such date, should also be able to tell us what hurricane or tornado, etc. is coming. As a minimum, they should be able to take historical experienced weather data and input it into their models and accurately correlate the models’ outputs with the later experienced data.
If they can’t do either, they are snake oil hucksters.
Their models suck.
We are still colder than the Middle Ages Warming Period, which was a natural warming cycle, which they tried to refute as a localized phenomena but failed, since it was proven to be global. They cannot explain nature, yet they can explain Co2?
We are within natural variation.
