Junk Temperature Measuring Network Means the Met Office Cannot Prove There’s Been a “Dramatic Increase” in Temperature – Watts Up With That?

From THE DAILY SCEPTIC

by Chris Morrison

Earlier this month, the Met Office claimed that climate change was causing a “dramatic increase in the frequency of temperature extremes and number of temperature records in the U.K.”. Given what we now know from recent freedom of information (FOI) revelations about the state of its ‘junk’ nationwide temperature measuring network, it is difficult to see how the Met Office can publish such a statement and keep a straight face.

The claims were the headline findings in the operation’s latest state of the U.K. climate report and are said to be based on “observations from the U.K.’s network of weather stations, using data extending back to the 19^th Century to provide long term context”. That would be the network where nearly eight out of 10 stations are deemed by the World Meteorological Organisation (WMO) to have ‘uncertainties’ – i.e., potential errors – between 2-5°C. The same junk stations that provide ‘record’ daily temperatures often in the same places, such as the urban heat furnace that is Heathrow airport. The same junk measurements that the Met Office uses to claim collated measurements down to one hundredth of a degree centigrade.

The WMO rates weather stations by the degree of nearby unnatural or natural temperature corruption. Classes 4 and 5 have possible corruptions of 2°C and 5°C respectively and these account for the vast majority of the Met Office sites. The WMO suggests that Class 5 should not be used to provide an accurate measurement of nearby air temperatures, yet nearly a third of the Met Office sites are classified in this super-junk category. Only classes 1 and 2 have no uncertainties attached and only these should be used for serious scientific observational work. But, inexplicably, the Met Office has very few such uncorrupted sites. Even more worryingly, it seems to show no sign of significantly increasing the paltry number of pristine sites.

Human-caused and urban heat encroachment are the problems, with extreme cases found at airports, which can add many degrees of warming to the overall record. But this has been known for some time, and it is a mystery why the Met Office has not done anything about it. Recent FOI disclosures reveal that over eight in 10 of the 113 stations opened in the last 30 years are in junk classes 4 and 5. Worse, 81% of stations started in the last 10 years are junk, as are eight of the 13 new sites in the last five years.

It’s almost as if the Met Office is actively seeking higher readings to feed into its constant catastrophisation of weather in the interests of Net Zero promotion. Whatever the reason – incompetence or political messaging – serious science would appear to be the loser. As currently set up, the Met Office network is incapable of providing a realistic guide to natural air temperatures across the U.K. Using the data to help calculate global temperatures is equally problematic.

Of course, the Met Office can rely on its helpful messengers in the mainstream media not to breath a word about this growing scientific scandal. The central plank of Net Zero fear-mongering is rising temperatures and claims that ‘extreme’ weather is increasing as a result. Temperatures have risen a bit over the last 200 years since the lifting of the mini ice age, the clue to the pleasant bounce being obvious to all. But this is not enough to force the insanity of Net Zero on humanity, so fanciful climate models and bloated temperature databases are also required. The compliant media are uninterested, but the cynicism and outright derision over the Met Office’s temperature antics are growing. The Met Office regularly posts on X and it cannot be unaware that a growing number of replies are less than complimentary. Last week, it announced the “warmest day of the year” based on measurements taken at Heathrow. The following are a few of the more polite comments it received:

What is it about LHR that could make it hotter than surrounding areas? I will give you a clue – concrete and hot jet exhausts maybe?

Real temperatures should be taken out in the open away from London.

…manipulating temperatures to fit the climate agenda.

Might as well measure inside an oven.

It’s all made up to fit your agenda.

I have a brighter red highlight in my fonts that I can lend you if you think the one you choose does not does not push the propaganda enough!

Remind us where you were taking temperature recordings in the last century, because it wasn’t on the roasting tarmac of airports.

Urban heat islands should not count and you know it but the grift continues.

In its recent annual report, the Met Office claimed that “our new analysis of these observations really shines a light on the fastest changing aspects of our weather as a consequence of climate change”. It is not just temperature data that is brought to the Net Zero table, but rainfall as well. The indefatigable investigative journalist Paul Homewood took a look at how the Met Office spun precipitation in a recent article in the Daily Sceptic. He agreed with the Met Office’s claim that rainfall has risen since 1961, but asked why that year was chosen to start the timeline. The graph below shows why.
