The UK is suffering from economic gloom and stagflation at once
This morning has brought more disappointing news for the UK economy. UK real gross domestic product (GDP) is estimated to have increased by an unrevised 0.1% in Quarter 3 (July to Sept), compared with growth of 0.2% in Quarter 2 (Apr to June) 2025. At first there is some relief that the third quarter was not revised lower. But then one spots that the second quarter of 2025 was.

As some EU leaders lose sight of the big picture in Russia’s war of aggression, reminder of 2 of my pieces: this on consequences if Ukraine loses: www.cer.eu/publications... ; & this on what Europe must do to ensure it doesn't: www.cer.eu/publications.... Only change: funding UA is now more urgent.
Does it matter if Ukraine loses?
Ukraine is retreating and Russia is advancing, militarily and politically. Western leaders seem to underestimate both the impact of Ukraine’s defeat and the West’s ability to prevent it.

Apparently there are new government comms directors, huge teams of press officers, and scores of comms Spads for ministers.

So what are they doing? How can they apparently have issued virtually nothing about the value of Erasmus?

Or are there those in Number 10 who don't want more EU reset?
On which note (UK government effort) - pretty dismal in terms of pushback against costs of Erasmus plus. Potentially forgotten if other negotiations deliver in a year's time. But a reminder that far better government comms over EU ties are needed in both London and Brussels.

Do read this thread in full if you care at all about migration. 👇🏻
Few thoughts on the "Polish exodus" from the UK.

1. It's not an 'exodus', it's a slow drip. We're fine, thanks.
2. Migration is really complicated.
3. The absolute cheek of the very same media attacking Poles for years lamenting their departure.
4. What you can do?

“Solar is no longer just cheap daytime electricity, now it’s anytime dispatchable electricity,” said Rangelova. “This is a game-changer for countries with fast-growing demand and strong solar resources.”
This is incredible (good news too): “After a 40% fall in 2024 in battery equipment costs, it’s clear we’re on track for another major fall in 2025…The economics for batteries are unrecognizable, & the industry is only just getting to grips with this new paradigm”

Batteries now cheap enough to make dispatchable solar economically feasible
Energy think tank Ember says utility-scale battery costs have fallen to $65/MWh outside China and the United States, enabling solar power to be delivered when needed.

In the midst of the darkest of times, a hero stands up for what is right. The brutal, deliberate attack against Jewish Australians celebrating Hanukkah at #Bondi Beach today is an abomination. For those murdered while celebrating the 1st day of the Festival of Lights, may their memory be a blessing.
This guy disarming the terrorist at Bondi Beach, Australia, can only be described as hero.

In line with my experience. We've heated our 1870s house in upstate NY w/ ground-sourced heat pump for past 12 yrs. House is reasonably insulated, but hard to make any old house really tight. "Experts" said we had to insulate more, at a cost of $40K, before heat pump would work. They were wrong.

No surprise: new analysis shows that heat pumps can deliver excellent performance even in older buildings with no meaningful correlation between building age & heat pump efficiency.

This is in line with my own experience of having a heat pump in a 1880 Victorian home with only modest insulation.
