Mystery Grows Over Met Office’s ‘Hottest Day’

Christopher Booker, The Sunday Telegraph

It was odd to base a claimed record of 36.7C (98F) on a single reading at Heathrow airport

No sooner had the BBC and all the usual suspects rushed to trumpet that last Wednesday was the hottest July day in the history of the world than more thoughtful observers, such as that diligent blogger Paul Homewood (on Notalotofpeopleknowthat), began raising their eyebrows.

For a start, it was odd for the Met Office to base its claimed record of 36.7C (98F) on a single reading at Heathrow airport, when it is well-known that thermometers surrounded by a vast area of tarmac can exaggerate heat by as much as 2 degrees. Even the Met Office’s own hourly record only showed its highest Heathrow reading on Wednesday as 35.9C, while four other sites nearby showed the day’s hottest recording at just 35C.

Even if 36.7C was genuinely the hottest July reading since records were kept, this would still have been way short of the 38.5C recorded at Faversham on August 16 2003; or that famous day, August 3 1990, when Cheltenham registered 37.1C and local records were broken all over the country, which still stand. I recall that afternoon showing my young sons the thermometer in our shaded West Country courtyard reading 98F, before taking it out into the sun to see it shooting off the top at 130F. […]

But nothing last week better conveyed the desperation of the warmists to convince us that the world is hotter than ever than a remarkable item on Tuesday’s Today programme, when Lord Deben (aka John Gummer), bursting with self‑righteousness, broke the record for the largest number of absurd claims ever squeezed into a single three-minute interview: such as telling us that Bangladesh will soon be so intolerably hot that we shall see “170 million displaced people wandering the world, looking for somewhere to live”.

So insistent was the noble lord that everything he was saying was “absolutely true” that John Humphrys eventually suggested that some people might think his wild assertions sounded “more like a religion than a science”. Gumboot hilariously replied that people had better believe him – because “even the Pope” was now agreeing with him.
