Parents & anyone else up early on Christmas morning: there’s a bright pass of the International Space Station over the UK, just after 6.15. Well, I say it’s the ISS. Could be Santa heading home… Exact timings for where you are at www.heavens-above.com/PassSummary....

It is likely that 2025 will be the warmest year on record for the UK. Why does this matter? Burning fossil fuels is warming the planet, including the UK, causing heatwaves to get hotter. For Central England this is happening 2x faster than the mean change. www.bbc.co.uk/news/article...

For all you global temperature aficionados, HadCRUT5 is now updated to November. 12-month running mean timeseries and HadCRUT5 Analysis map for November. For the December update -- and release of the 2025 annual temperature data -- put 14 January in your diary.

The 6 new model simulations spanning the time period 1750-2014 which are described in this post are now available to download from here: dx.doi.org/10.5285/9487...

Met Office 2026 global temperature forecast released today: very likely a fourth consecutive year above 1.4 C and >1.5 C possible again. Highlights the vanishingly small headroom we have to stay below 1.5 C to avoid the most severe impacts of climate change. www.metoffice.gov.uk/about-us/new...

It’s simply not possible to overstate how important NCAR is to US and world science. We need to fight this with everything we’ve got.

Looking back at 2025 (through mid-December): a snapshot of the climate fingerprint on the UK’s unusual, at times excessive, heat. The Climate Shift Index signal ramps up in spring, then flickers on and off in waves into early September. Notice how it shows up again throughout November.

As we move into the final days of the year, 2025 has just overtaken 2022 as warmest year-to-date for Central England. Given the forecast, it looks likely that 2025 will end up being the warmest calendar year for this region since records began in 1659. The top 3 warmest will be 2022, 2023 & 2025.

I loved being a guest on The Infinite Monkey Cage. Sad to hear that Robin has had to resign as presenter because of opinions expressed outside of the show. His energy, passion and humour are key reasons why the show is so popular.

New study in Nature by Lin et al shows how the sea-level rise from the melting Ice Age ice (a total of 120 meters rise) ended thousands of years ago. Until our fossil fuel use started a new phase of rising seas. Graph shows the global mean rate of sea level rise. 🌊 www.nature.com/articles/s41...
