Looking forward to a 4th term an IPCC Lead Author! I've dotted around a bit over the years:

AR4 - WG1 Radiative Forcing (focussing on land use)
AR5 - WG2 Terrestrial Ecosystems
AR6 - WG2 Water
AR7 - WG1 Global Projections

Always fantastic to work with international colleagues and learn from them

Science is always more interesting when your predictions are wrong! 🤓😅

Glen Peters @glenpeters.bsky.social · 4d

My pet theory remains that most of the fuss about 2023 was because most of the projections (from late 2022) were wrong since they got El Nino wrong (they thought it was La Nina).

It is not easy getting El Nino right either: 2023 is either La Nina or El Nino depending on lags and annualisation.

Prof Richard Betts @richardabetts.bsky.social · 4d

Except for 2023, our predictions of the annual CO2 rise at Mauna Loa conditional on the preceding April-March Nino3.4 SSTs have been better than what we’d predict based on emissions alone

April-March chosen based on @chrisd-jones.bsky.social previous work - we’ve not revisited that since 2023 yet!

This all sounds great for train travel from London to continental Europe! New Eurostar services to Cologne, Frankfurt and Geneva and shorter waiting times at St Pancras 😀

The results from Wales and elsewhere show a 25% reduction in casualties. So if you keep a 30mph limit on urban/village roads where pedestrians and cyclists mix with motors you are imposing 1/3 more casualties on your community. It's why Transport Professionals are saying #20splenty

Read this from Ben Santer (very famous climate scientist for those who don’t know) about what NCAR means and what dismantling it will do.

Threatening NCAR, Trump administration seeks to extinguish a beacon of climate science

The Trump administration’s world view is that the US doesn’t need a climate science brain trust because it doesn’t like what the brains say.

The objectives of a default 20mph were explained very well by this Welsh Assembly Member in 2018. And its great to see that since implementing 20mph as the default for urban, built-up areas there have been over 1,000 fewer casualties on those roads.

Will today, 14th Dec 2025, be the last day of a UK Gov 15-year era when it has had no English Road Safety Strategy. Whilst other UK nations have moved forward with their own RSS and the acceptance of 20mph as a transformational norm for communities, England is still locked in a postcode lottery.

More than 250 people who were exposed to measles, including dozens of unvaccinated school-aged children, are quarantining in South Carolina as the state wrestles to contain an outbreak that has sickened more than 110 people.

Hundreds Quarantined in South Carolina as Measles Outbreak Shows No Sign of Slowing

The outbreak shows no signs of slowing, likely because of the affected area’s “lower-than-hoped-for vaccination coverage,” a state health official said.

Fab week in Paris kicking off the writing of the IPCC 7th Assessment Report, and especially good to have authors from all 3 Working Groups together. I’m in Working Group 1 Chapter 6 (Global projections) - we have a great team led by @flimsin.bsky.social, Vimal Mishra and Tianjun Zhou. Let’s go!! 😀
