A Very Serious Consequence Of Climate Change–Sadiq Khan

July 16, 2022

By Paul Homewood


It seems that Sadiq Khan has been sending this extremely irresponsible and misleading warning out to his citizens – (my bold):




There is no evidence whatsoever that the heatwave is a “consequence” of climate change. It is a weather event, one which is the direct result of an extremely rare set of meteorological conditions.

The clue to this lies in the weather models run a few days ago, which showed an extremely unlikely chance of temperatures reaching 40C. Weather models are run over and over again thousands of times, in order to provide a range of outcomes varying around very small changes to assumptions. In other words, the meteorological set up we are now likely facing was considered as an extreme outlier just a few days ago.

Even accepting that average summer temperatures in the UK have increased by a half a degree or so since the 1940s, the upcoming heatwave would still have occurred a century ago, albeit with temperatures a half a degree lower. In those days, of course, Londoners were much less prepared to deal with hot weather.

To label it as “potentially dangerous” is also irresponsible scaremongering, given that millions of Brits fly out to Spain and other countries, where temperatures are regularly much higher.

Of course, people need to take sensible precautions, but they don’t need the Mayor lecturing them.

While Khan is playing political games with climate change, I would ask whether he ever puts out red warnings every winter when it gets cold. Surely he knows that many more people die in the cold of winter?

And that death tolls in summer are always the lowest of any season, heatwaves or not.

Surely he would welcome a slightly warmer climate?




The Met Office has issued its first ever Red Warning, which spans most of central England:




Forecasts for towns such as Manchester and Leeds, which are encompassed by the warning indicate temperatures might reach about 36C.

Yet temperatures of 36C are certainly not unprecedented in the South East, but were never accompanied by Red Warnings?

Are the Met Office playing politics too?

    This ‘red warning’ is indeed a very serious consequence: of climate change hysteria.
    But phew! —I’m just outside the red blob, so I’ll survive.
    Is the Met Office playing politics?

      A GB News presenter made the point that back in the 1970’s 80’s and 90’s the predicted hot spells on the British Isles weather maps were not emblazoned with fierce red and orange smothering blobs but sun motifs and the temperature forecasts next to them…….This Red Warning sensationalism from the Met Office is just a classic ‘nudge unit ‘ extension of covid fearmongering fanned by the media and climate alarmist crusaders like Sadiq Khan …….This short heatwave will be nothing like the stifling summer heatwaves of 2003 , 1976 and 1911 or even the hot dry weather leading up the Great Fire of London in the 1660’s

    Of course the Met Office are playing politics. Now they are part of BEIS and not the MoD they have become a politically driven organisation. The death of another formally respected body.

    And this morning we have 102f for Tuesday according to weather-forecast. But that might change by this afternoon as it did yesterday.

        Yes, BBC just forecast 40C for London on Monday but Met Office says 35C for Chelsea. Who is kidding who?

    July 16, 2022 11:36 am forecasts 100F Monday, low 76 (!) into Tuesday for London.

    Hysteria aside, that low is a problem, too. We’ll be in the mid-90s most of the week here, but our overnight lows will be lower than that. I haven’t seen a low that high in years.

    Attribution to ‘climate change’ is argumentum ad ignorantiam.

      Are you seeing the same discrepancies on wunderground between the 10 day headline number and what you get if you follow the red graph with your mouse? I get 1 or 2 degrees lower on the graph which it backed up in the hourly.

      • Gamecock permalink
        July 16, 2022 4:08 pm

        Yes, but it is typical of wunderground forecasts here, too.

        They are now saying 101/77.

        I looked ahead on hourly to their Monday forecast. Highest hourly number is indeed 99.

        But, more importantly, I see the dew point is under 50. Your humidity will be down to 20%. That is going to significantly reduce the impact of the temperature. I’d say enough to take you out of the red zone.

      • Gerry, England permalink
        July 17, 2022 10:14 am

        I have emailed wunderground about the discrepancy.

        Yes, the humidity is less than 15% during the peak temperature and so on the weather-forecast page in the ‘feels like’ field when the peak is 100f it will feel like 88f. That is quite a difference. Anyone know why?

      Surely everyone in Penang is dead? That comparatively cool spell equates to a wet-bulb temperature of around 27C, fully 6 degrees higher than that predicted for England early next week.

      • July 17, 2022 12:43 pm

        Not so, the “feels like” temp is 6 or 7 degrees higher due to the very high humidity here

    • Stephen Hedges permalink
      July 18, 2022 9:16 am

      My point was that the current weather appears to be comparatively cool for Penang which I always found to be even hotter than KL, where I lived for a decade. I highlighted the “wet bulb” because the high temperatures we are about to experience in England are accompanied by exceptionally low humidity. The “feels like” temp. is a useful but different measure entirely (during the 2016 El Nino, I recall it reaching 54C in the Philippines).

    On cold weather related deaths in London, which Sadiq Khan would likely have no interest in, there was a scientific paper published in 1796 “Of the influence of cold upon the health of the inhabitants of London” by William Heberden:

    January 1795 was a very cold month, the coldest in the Central England temperature record at -3.1 deg C. In London, Heberden reported that there were 2823 deaths (burials) with 717 aged over 60.

    But the following year 1796 had a much milder January, resulting in 1471 deaths with 153 aged over 60. The old age death toll in London had dropped by a factor of 4.7 going from a cold to a milder January.

    • Dave Andrews permalink
      July 16, 2022 3:31 pm

      The i newspaper had a piece on 14th July saying figures from the Office of National Statistics indicate that “climate-related mortality” -deaths from extreme cold or heat- had fallen by around 27,000 a year since 2001. Fewer deaths during warmer winters have more than offset rising mortality rates during heatwaves.

      Quoting directly from an ONS report earlier this year

      “We found relatively little increase in deaths caused by warmer weather and a reduction in deaths caused by cold winters, leading to a net decrease in deaths.”

    Paul “even though temperatures have increased by half a degree since the 1940s ” is hard for me toi reconcile with the glorious summers that I remember from my childhood in the (fairly typical) resort of Rhyl. All those resorts developed since the Victorians invented leisure time and the benefits of the seaside (ozone etc). The open air swimming pools opened in May with water temperatures of around 57F and reached well into the 70s by July. By 1980 when most of them were closing the water never got above the mid 60s. I was not in the UK in 1976 so I can’t remeber the heatwave, but overall the first half of the 20th century seemed to me to be much hotter.

      John I think Sadiq Khan – who defended Nation of Islams Louis Farrkhan and the Jew hating suicide bomber endorsing Muslim Brotherhood cleric Sheikh Qaradawi – should be reminded of his pronouncement that its all ‘part and parcel of living in a big city ” …Its amazing Khan is more concerned to promote fearmongering about a hot London day forecast to be not much warmer than August 9 1911 during Londons great 1911 heatwave [ 40 000 French died during that summers sweltering heat ] than violent crime worsening under his mayorlty ..Then again his latest bout of climate alarmist hysteria may serve as a convenient distraction from Khan’s mounting problems …. It is no suprise to learn that London’s institutionally corrupt and shockingly incompetent Metropolitan Police have recently been placed under external control ‘special measures ” …..

      .He has the nerve to entitle his disgraceful mayoralty a ‘public service ”

      Tony Heller recently divulged this archived report in The Guardian [ London Greater London ] dated Friday August 11, 1911 : ” 100 Degrees in London ”

      ” From official information it is now clear that Wednesday [ August 9 ] was not only one of the very hottest days known in the south east of England but absolutely the hottest for the seventy years during which observations have been kept at Greenwich ……In the London area it was the hottest day of which there is any authentic record . Hitherto the highest shade temperature recorded at Greenwich Observatory has been 97 but that has now been beaten by three degrees . The maximum thermometer at the Observatory [ of course daily screened ] attained the unprecedented figure of 100 sometime on Wednesday afternoon . In several other parts of London the reading of 97 was registered ”

      There is nothing new under the English sun and the hot temperatures are not a ‘very serious consequence of climate change ” .The 1911 and 1976 heatwaves will not be surpassed this summer
