There are actually scientific methods for attributing specific events to global warming or not, probabilistically. I.e. although you can never say with perfect certainty "this heatwave was caused by global warming", you can say: with global warming this heatwave has a probability 0.1 (once in ten years), but without global warming it would have a probability of 0.001 (once in a thousand years).

We seem to be having several "once in a thousand years" heatwaves per decade these days.
