Also, killing off the Feedin Tariff for solar had a very detrimental effect on installation numbers for quite a while, and that was after tapering. The solar industry slowly recovered, but that was due to rapidly declining costs that we won't see for heat pump installations.

I hope Andrew is right about crossed wires. I think it's fair to say that a lot of people think that they can't get a grant now, because they are above the threshold for a warm homes grant and already confuse the two schemes.
I think part of this story (on eligibility for heat pump grants) is likely to be nonsense - I'll explain in a thread below.
But it is clear that the Treasury wants to abolish the ECO levy, which funds upgrades for fuel poor homes. This would be a serious mistake

Sigh. We're already well behind on installation targets and this is equivalent to slamming a foot on the break. Very short sighted sudden policy change.

Hundreds of thousands of homeowners will lose their right to subsidies for eco-friendly heat pumps as a result of government plans to bring down energy bills at the budget.
Rachel Reeves, the chancellor, is planning to announce a series of measures to bring down energy bills amid concerns the country’s stubbornly high cost of living is driving millions of voters to Reform UK. Continue reading...

Fossil CO2 emissions continue to rise in 2025 while the terrestrial carbon sink recovers to pre-El Niño strength.
The key findings are covered in two reports this year:

While fresh air is good, trying to clean the air chemically is not. The atmospheric chemistry community has been saying this for a long time; the best ways of cleaning indoor air is physical removal (filters/sorbents/air exchange).
New air cleaner paper! @airqing.bsky.social challenged an oxidation-based cleaner with an air freshener, and saw tons of chemistry. In particular, ethanol (a common ingredient in cleaning products, and ubiquitous indoors) oxidized to form acetaldehyde and formaldehyde.

The current net zero strategy has its flaws, but all the counter proposals amount to ‘what if nuclear was cheap and quick to build?’ ‘What if everyone agreed a carbon tax? What if climate change just wasn’t so bad? And they call themselves realists.
On politically naive Kathryn Potter is interesting. She bangs on about how nuclear not renewables is THE answer. And says nuclear should be so much cheaper. But then implicitly acknowledges that long term only way of achieving those cheaper prices is political stability. So realistic for the UK!!

It got more exciting as we got very close to the working steam engine. Not sure I have ever seen a centrifugal governor in operation before. Apparently it wasn't working quite correctly today, and small changes in piston speed affect the quality of the weave. Fascinating.

I reckon the most interesting subset of discourse here is when presumed [good] factors are actually either actually bad, or there to downplay or dismiss the bad even if the amount of good is way smaller than the bad.

Does bonfire night impact indoor air quality. In my fairly well insulated but probably fairly leaky bungalow, the answer is yes. PM2.5 reached 50ug/m3 last night. They dropped back to <20 indoors overnight. The sensor is now outside at 40 ug/m3.
