THE Met Workplace would definitely such as you to assume they’re. In a current weblog submit, titled ‘July 2022: A dry run for UK’s future local weather?’, they claimed ‘Met Workplace local weather change projections spotlight an growing pattern in the direction of hotter and drier summers for the UK.’
Definitely, it was extraordinarily dry in England and Wales final month, although much less so in Scotland, with excessive strain techniques dominating the climate. However was the month of July that uncommon, and does the information present that droughts have gotten extra widespread?
The Met Workplace’s personal information reveals neither to be true:
Since 1836, there have been eleven different Julys which were drier. So as, with the driest first:
1911
1868
1869
1935
1999
1977
1898
1885
1864
1984
1955
Notice that, regardless of the hyperbolic reporting, this July was not whilst dry as 1999. And it’s abundantly clear from the above chart that there isn’t any pattern to Julys turning into drier. As a substitute, the entire of the file relationship again to 1836 is dominated by big swings from 12 months to 12 months, from extraordinarily dry to extraordinarily moist. In different phrases, basic British climate.
It has additionally been a really dry begin to the 12 months as a complete, however once more the information demonstrates that these at the moment are a lot much less widespread than prior to now. General, 2022 ranks as solely the tenth driest January to July:
The south of England has been worst affected. However even right here, this 12 months’s drought is much from unprecedented, and is certainly now a rarity:
After all, it was the identical clowns on the Met Workplace who predicted 9 years in the past that wetter summers can be the norm in Britain; you guessed it, due to world warming!
July heatwave in context
THE nation appears to have misplaced its collective thoughts over two days of scorching climate, however how scorching was the month as a complete? Most likely not as scorching as you could have been led to consider!
In Central England, amongst the most popular components of the nation, July 2022 was no hotter than 1759, 1818 and 1911. All instructed, it ranks simply 20th warmest, 1.6C colder than July 2006.

After all, the Met Workplace didn’t work itself up right into a lather in these earlier instances. As an illustration, July 1934 had the identical imply temperature of 18.2C as final month. The Month-to-month Climate Report on the time merely famous that it had been ‘heat and sunny’!

However they have been merely meteorologists again then, with out an agenda to hawk.
Blackouts are looming
EVERY 12 months the Nationwide Grid publish their Future Vitality Eventualities (FES) to persuade everyone, not least themselves, that the UK can get to Web Zero in 2050 with none issues.
This 12 months’s version remains to be as filled with wishful pondering as ever. Overlook about 2050, even the figures for 2035 don’t stack up. There are 4 situations offered, however let’s give attention to the Client Transformation state of affairs (CT), which is pretty center of the highway, and assumes widespread uptake of electrical automobiles and warmth pumps. The opposite three situations should not a lot completely different.
Beneath is the anticipated electrical energy combine:
By 2035, as you’ll be able to see, wind and photo voltaic will account for 78 per cent of electrical energy output. Dispatchable sources, together with gasoline (with carbon seize), biomass and nuclear, will provide solely 17 per cent. Apparently we can have a lot energy that we shall be exporting 88 TWh a 12 months, assuming anyone truly desires it.
You’ll be able to most likely already sense that the grid merely gained’t be steady with such a excessive load of intermittent renewables.
Electrical energy demand is about to rise quickly, as fossil fuels are phased out. Beneath our CT state of affairs, peak demand will rise to 87 GW by 2035.
As for the projected capability, the Nationwide Grid dare not even present it on one web page collectively. Their information nonetheless offers this:
Look very carefully, and you will notice that dispatchable capability – nuclear, bio and gasoline – present solely 44.2 GW; and half of that’s unabated gasoline, which won’t be allowed for much longer.
So the place, pray, do they get the remainder of that 87 GW from?
For a begin, it’s best to word that the height demand quoted in FL-04 is ACS – they clarify: ‘ACS demand for electrical energy is the utmost demand over a median winter and is according to the therapy of demand within the electrical energy Capability Mechanism. As a median it has a 50 per cent likelihood of being exceeded in any given 12 months.’
In different phrases, it’s not ‘peak’ in any respect. You’ll most likely want so as to add a minimum of 10 per cent to cowl years of maximum demand. Additionally, you will have to construct in a security buffer to permit for plant outages – it’s regular to imagine that solely 85 per cent of capability shall be accessible at any given time. Lastly, you additionally want to permit for line losses. All in all, to produce that 87 GW, you would wish about 120 GW of agency capability.
The projection assumes 109 GW of wind energy and 47 GW of solar energy. The latter is successfully nugatory in mid-winter, when it could provide solely about 2 GW at most on common. And as we all know too nicely, wind energy can plummet to nicely under 10 per cent of its capability for days and weeks on finish.
Even when we assume that wind energy can generate at 10 per cent of its capability during times of chilly anti-cyclonic climate, we are going to nonetheless be about 50 GW quick.
What about interconnectors to Europe, then? The plan permits for 18.8 GW, which nonetheless leaves us nicely quick, even assuming the Europeans have any surplus energy to promote.
The FES reckons that we are able to shuffle demand round in the course of the day, with good meters, vehicle-to-grid and demand response. Even assuming that demand could be completely smoothed every day, it will possible lower peak demand by solely 10 GW, on condition that winter demand fluctuates by about 20 GW from peak to trough.
So what’s the FES reply to this conundrum?
Batteries! They plan to have 28.9 GW of battery storage. However, as they acknowledge, these batteries will be capable of retailer on common solely an hour or two’s price of electrical energy. This can be positive for assembly peak demand in early mornings and evenings. However they are going to be completely ineffective for supplying energy throughout these days and weeks on finish when the wind stops blowing.
There is just one conclusion that may be drawn from this actually horrifying and childishly naive evaluation – there shall be electrical energy rationing within the not-too-distant future. Not will we be capable of depend on a safe, dependable power provide.
And this all seems to be deliberate coverage.
We have been warned. In 2011, the Nationwide Grid’s then CEO, Steve Holliday, instructed Radio 4 that the times of completely accessible electrical energy could also be coming to an finish. Households must get used to solely utilizing energy when it was accessible, quite than continuously. He stated: ‘We’re going to change our personal behaviour and eat it when it’s accessible and accessible cheaply.’
