It isn't necessarily denialism nor shilling to question the validity of predictions. It's a good thing.
Unfortunately the whole topic has become breathless "99% of scientists!" and tied in with social economic programs to the point I'm not convinced any more. To say nothing of failed predictions.
Ya, I believe C02 _should_ warm the earth based on the science. But this whole world is ending thing I'm waiting to actually see something.
For the record, I've been hearing this for over 30 years as an adult and so far not much. Perhaps one day it will all catch up, but I'm skeptical at this point.
