I've seen several Big Climate Accounts™ post about how the recent winter storm was made worse by climate change. It's a convenient narrative.

s
But what is "worse"? Colder temperatures? More snow? More freezing rain? Is there any primary literature supporting the idea of worse snowstorms?

"touché par des tirs" is the new "assassiné"
Un homme est mort après avoir été touché par des tirs de l’ICE, la police de l’immigration, à Minneapolis, seulement quelques semaines après un drame similaire qui avait causé la mort d’une Américaine du même âge.

The extreme cold across eastern N America is due to the Alaskan Ridge regime, which on average brings the coldest winter weather to this region.

Is this happening more often?

No. During the modern warming era, there has been no observed trend in the occurrence of this regime at this time of year.

On the balance of probabilities those warning of disaster look much more likely to be right than those complacently arguing there is nothing to worry about. Even the spooks are worried, and they are right to be.

Back in the Autumn, No.10 blocked the publication of a report into the risks the UK could face if climate change causes ecosystems around the world to collapse. On Tuesday, after an FOI request, it published the report. But it turns out, that wasn't the full version. www.thetimes.com/uk/environme...

This is my top pet-peeve!
If you are troubled by selfish people burning wood in your neighbourhood, now a leading cause of air pollution linked to illnesses from asthma to miscarriage, dementia and heart disease, now is your chance to make your views known.
Tens of thousands of lives are being shortened in the UK by air pollution, according to the Environment Agency. What can the Government do to protect public health and the environment?

A short thread about the back story behind our new study. 🌊
A pile of evidence suggests the Atlantic overturning #AMOC (and its surface branch North Atlantic Current) has slowed. But some colleagues were sceptical, arguing the Norwegian Current and its deep return flow haven't slowed. 1/6

China has now reacted to the news that the Trump White House wants to pull the US out of a range of UN orgs and entities, such as the UNFCCC and IPCC:

"No matter how the situation may evolve, China will stay committed to multilateralism"

Trump is probably focused on the money he wrongly thinks he'll make from Venezuelan oil. But he's not a details guy and nobody has thought through the details. Essentially, the US has taken over Venezuela by mistake. Stranger things have happened, but not many.

A picture is worth 1000 words...

This appeared on the BBC News today, showing the increase in solar electric generation in the UK.

Not sure who produced it, but genuinely think this is a genius piece of scientific communication - the construct and choice of colour scale is near-perfect.

Chapeau!

2025 has been a historic year for clean energy in UK, with renewable project approvals reaching a record-high 45 GW — nearly double of 2024.

This surge was driven by an exceptional rise in battery storage capacity, which almost doubled to 28.6 GW, alongside strong growth in offshore wind & solar.

Overall my predictions for 2026 are similar to recent estimates from the UK Met Office and James Hansen. But my 2027 estimate is a bit below Hansen's, even if the error bars are inclusive of it:
