Orsted, majority-owned by the Danish government, has decided to cancel the 2.4 GW Hornsea 4 offshore wind farm. The final investment decision had been expected later this year – they've taken it early, and it's a negative.

What stands out to to me in this analysis of open-ended "what's important to you?" questions asked by Opinium is just how high up climate and the environment comes, often closely behind the NHS
So I think this would be the natural follow-on from this research to be fair!
It's a bit harder to say with some of the more experimental techniques because base sizes can be a little small, but we did find this for the open-ends we ran (again, with a reminder that this skews towards salience!):

Global fossil CO2 emissions keep growing, 0.8%/yr in the last decade. We (& IPCC AR6) argue the lower growth rates in the 2010s compared to 2000s was due, partly, to growth in renewables & displacement of coal.
So , why do emissions continue to grow, 1.1% in 2024, and projected 1.1% in 2025?

Since the 1990s I've thought that surely the path for less developed countries is to skip fossil fuels and go straight to renewables.

The same for journalists. If a politician or business leader spits out 1.5C or net zero, ask them how fast emissions need to drop to reach net zero in 2050, and how fast they are dropping today. Point out the contradiction. Make them explain it.

Not ripping the plaster off to instead go with many little fiddly policies is anti-growth, and is unlikely to restore sufficient "headroom" to avoid repeated further tax rises at future budgets.
Out of a range of bad choices, raising income taxes was the least-worst, in the round.

Too much analysis was still treating breaking the tax pledge as “just another unpopular decision” rather than recognising consequence of breaking a promise which defined an election for the public. If is correct the govt won’t now break it they may have avoided a deeply scarring loss of public trust
