FWIW, I think it's quickly becoming an academic question. Last year had an extreme heat wave in Canada (worst in record) and a cold wave in Texas. Sure, last year might have been a freak year, but the thing with unmitigated climate change is that a "freak year" quickly becomes a "normal year" which then becomes a thing of the past. For example, see the graph in [1], and imagine we only have data up to 1999. The year 1998 sticks out like a sore thumb - it was a freak hot year. Except that it became the new normal temperature in the 2000s, and then the most recent six or seven years have handily beat it. It will be an unusually cool year if it happened now. We are transitioning into a world where "worst since weather records began" is a regular phrase at evening news. When a town burns down, will its residents even care if the particular fire was linked to climate change or not?
