This is a false equivalence. The reasons they’re being linked are important too. When Trump and others point to cold snaps as evidence against climate change, they’re just drawing a straight line from one to the other with no rationale or explanation in between. When extreme events like this are linked to climate change, they’re presented as illustrative of a well studied phenomenon that definitely causes this sort of thing to happen.

It’s like if I take the Lord’s name in vain and then get sick and you tell me this shows that I shouldn’t swear. Then you lick a handle on the subway and get sick and I tell you this shows how disease is transmitted by germs. The two may look superficially similar, but the underlying reasoning is important.
