So much for papal infallibility.
Papal infallibility doesn't cover climate change.
Matters of dogma only. And then only with a bunch of caveats.
For the umpteen-billionth time, the Pope’s stupid comments endorsing the Global Warming Hoax have absolutely nothing to do with Papal Infallibility.
The temperature of the Earth is not part of the teaching of the Catholic Church. Therefore, the Pope can say any idiotic thing he pleases about that subject, and Papal Infallibility is not involved in any way.
