Here’s the thing. The area affected by this heatwave is about 1/360 of the earth’s land area (I used the area of Washington and Oregon as an estimate - I know there were parts of Canada affected too, so that’s probably a lowball estimate). But for the sake of argument, let’s say this was a 50,000 year event on average. If you divide the earth into 360 equal parcels of land and OR/WA is one of them, you would expect one of these parcels to experience a 1-in-50,000 year event about once every 50,000/360 = 140 years. But I feel like I’ve read in this thread that the Siberia event last year was also of similar magnitude (and did someone say the March 2012 event in the Midwest?). So instead of once every 140 years, we’ve now had it happen to 3 of these 360 parcels of land in 9 years. That’s statistically significant and a strong indicator that the dice are loaded.
