As a recovering statistician this graph from World Weather Attibution scares the living daylights out of me. 

What it shows is the highest annual temperatures over the last 70 years in North Western America noting that the blue line represents climate at the end of the 19th century and the red the climate as it is today. The highest observed average temperature over this period was ~35 °C (95 °F) and the highest possible temperature (top red line) according to the probability predictions (GEV) is  ~37 °C (99 °F). What we saw last month was 39.5 °C (purple line) which according to past data is statistically impossible even over a period of 10,000 years….What this likely means is that the climate has changed in a massive way that we don’t yet understand….and that is what scares me.
