I didn’t see anywhere in the article where they blame global warming on man. The only thing blamed on man in this article is the fact that these pythons have been transported to the United States and then released into the wild by owners who didn’t want them anymore.

it never happened before the past few decades,

Forest fires happened in the past too but that doesn’t mean some aren’t caused by man now. You have to look at all the current evidence not just the past.

That the earth is currently warming is a fact which even you don’t dispute. That means that certain regions in the United States are now more favorable to some species than they may have been in the past. Blaming this article on “climhysterics” is a real stretch (no pun intended).
