Checking my facts before hitting send does not make me a expert.

As ever, individual weather events, no matter how catastrophic, can't be ascribed to global heating with certainty. But the cluster of events this year across the world should be worrying us: unprecedented combinations of heat and drought in North America, China and Europe and now destructive floods in southern Pakistan following record rainfall, to name but a few making the headlines in just the last two or three months. Between 1911 and 2003 the UK highest temperature record stood at 36.7°C. In 1990, then 2003, then 2019, it was beaten. Last month the previous record of 38.7° in 2019 was wiped out not once but at 46 different weather stations, reaching 40.3° at one of them.

Of course, the deniers will always find grist for their mill. The North Atlantic hurricane season has got off to a very slow start. And there's always the next cold snap...
