Welcome to global warming. It's gonna be a wild ride.
I recall the last 5 Summers being crappy, cold and wet. Was that global warming too?
It's hard to say if a particular heatwave is due to global warming. The press will often imply that it is, whereas scientific bodies tend to be more cautious. We are supposed to expect a greater frequency of heatwaves into the future however as mean global temperature increases. How severe those will be - and how frequent - is uncertain.
Africa only having its hottest temperature now, because climate scientists reject the 58 Celsius reading posted in 1922
