Average heavy rain days (>10mm) per year increased from 17 to 19 over the last 50 years, but average rainfall on a heavy rain day remained the same (14mm). NO sign of floodmageddon #climatecrisis in England, anyway.

October has proven that renewables are useless to power the UK. In the last week there has been no wind and little sun. Fossil fuels supplied 60% of UK electricity and renewables just 10%. Even with 5x renewables and a £400 bln battery the lights would still be off @Ed_Miliband

For UK renewable energy aficionados, the last week is an object lesson as to why they are hopeless. No wind, little sun, lights on only thanks to gas (and imports, nuclear and tree-burning). Batteries? Maybe, if we have £300 billion to spare.

This is no way to power a modern economy. £250 billion of heavily subsidised intermittent renewables contributed just 16% of UK power over the last week. Thanks goodness for reliable fossil fuels (55%).

£250 billion of spend on renewables has yielded 15% of UK power over the last 7 days. Sun is low on the horizon with virtually no wind either. Weather-dependent unreliables are hopeless in these conditions. Thank goodness for fossil fuels to keep the lights on!

A high pressure system has brought a massive wind drought to the UK. By the time it moves on we will have had a full week where the £billions of wind farm infrastructure power the square root of sod all and the lights are only on thanks to gas.

As we enter autumn it is worth looking back at the "hottest summer ever" in England. The record back to 1772 shows that only one day in summer 2025 was the hottest ever recorded, most of the time temperature was typical apart from 3 brief heatwaves and a couple of hot days.

October in England started with a day of typical temperature, both minimum and maximum. The record goes back 147 years.

England climate plots for September. After a warm dry summer September was completely normal in all respects. Data from @metoffice

Tuesday morning was one of the coldest days in 148 years in England (although nowhere near as cold as 1914), but fortunately the sun came out and the high for the day was typical. Summer is over?

We are short about 60mm of rain in the last 12 months in England.

After several warm days Sunday in England was 2 degrees C cooler than the average over the last 148 years.

I can't find anything about it on their website. There's a manifesto from 2019 but that doesn't mention gender issues.


Lamentable performance for unreliable renewable energy this evening. The grid is dependent on French and domestic nuclear, tree burning at Drax and propped up by reliable gas. Why double the system costs with parallel renewables when all the conventional backup is needed anyway?

Latest Energy Trends figures show steady increase in wind and solar capacity. But how does this compare to Ed Miliband’s CP2030 plan? A thread (1/n)

#OTD in 1943, German forces discovered mass graves of Polish prisoners murdered by the Soviets. The execution of 22,000 Polish officers began in 1940. The initiative to honour the Poles murdered in Katyń faced endless political obstacles in London. Why? britishpoles.uk/the-turbulent-…


A very warm 2nd April in the record of Central England Temperature #CET since 1878. Maximum was warmer than >90% of years, but minimum very average. #ClimateCrisis

Record sunny March in England since records began nearly 200 years ago. It is getting sunnier. #ClimateCrisis

March was a very dry in England, a year after a record wet March. Reversion to the meanor #ClimateCrisis?
