Congratulations to Piers Forster, Stephen Belcher and Gideon Henderson for well deserved CBEs in the New Year’s Honours!

Climate modelling work (e.g. GeoMIP) suggests that SRM geoengineering could work as a temporary/emergency way to cool the climate. This certainly does not justify large-scale implementation at this stage. However, open research on SRM needs to be encouraged, not driven underground.

FIFA is a joke. Infantino is corrupt. The beautiful sport had to fire him and clean out the rot. 🤬🤬🤬

I will be giving the final @gsiexeter.bsky.social seminar of 2025 "Living beyond limits: Consequences of missing the decisive decade for preserving our planet’s life-supporting systems." 10th Dec 2:30pm UK time. You can join remotely👇 universityofexeter.zoom.us/j/9357183404...

this shit is just beyond parody, man

Is this a joke, @fifaworldcup26.bsky.social? How corrupt are you to honour the most despicable US President in living memory?

Crossing a climate tipping point doesn't mean tipping is inevitable - a threshold can be temporarily passed if overshoot is short-lived. Limiting time over 1.5 °C would considerably reduce tipping point risks. New Ideas paper from @exeter.ac.uk & UKCEH: esd.copernicus.org/articles/16/... 🧪

I wrote this paper to work how the climate-carbon system could enter a runaway state 👇 esd.copernicus.org/articles/16/...

Fascinating new paper from Joe Clarke et al., which addresses the question: could the climate-carbon system suffer a self-sustaining runaway feedback? @gsiexeter.bsky.social @ukceh.bsky.social @bolincentre.bsky.social esd.copernicus.org/articles/16/...

How can we explore the future of the world's forests? Understanding the demography of their trees is key. In We took the new gen of global demographic vegetation models and held their roots to the observations. Thanks @annemarie-es.bsky.social for leading! nph.onlinelibrary.wiley.com/doi/10.1111/...

Just published, a land-mark paper by Annemarie Eckes-Shephard et al.! It assesses the performance of a new generation of Demography-enabled Dynamic Global Vegetation (D-DGVMs), that attempt to simulate the changing size and age structure of trees in forests.

"Infamy! Infamy! They've all got it in for me!" Keneth William's line from Carry on Cleo and one of my favourite one-liners. It's taken from Denis Norton's and Frank Muir's radio comedy show "Take It from Here".

New paper in ESD (esd.copernicus.org/articles/16/...) showing duration of overshoot matters for preventing climate systems from tipping. Crossing a tipping point does not equal tipping. Risk reduced if overshoot duration beyond 1.5 °C kept below a century. @coxypm.bsky.social @gsiexeter.bsky.social

Why on earth do the Tories want to keep people locked into high energy bills? And, come to that, why is the BBC citing Reform but saying nothing about climate science or renewable alternatives? Complete madness - except for the fossil fuel industry of course

Great interview with Tim about Global Tipping Points. www.theguardian.com/environment/...

Great to see the BBC covering our Climate Forum, which is taking place this week: www.bbc.co.uk/news/article...

Today is #ShowYourStripesDay I made a high resolution version of the global warming stripes by using monthly rather than annual temperatures.

🎉 We’re SOLD OUT! 🎉 The GTP conference is officially at capacity — thank you to everyone who secured their spot! 🌍💥 We can’t wait to welcome an incredible line up of speakers to Exeter, including special guest Tulio Andrade, Head of the CoP30 Climate Negotiation team. 🌱🗣️

We will overshoot 1.5°C of global warming, that is quite certain…but it’s not game over. The damage will be real — species loss, food insecurity, climate chaos — but if we act fast, we can still bring temperatures back down.

Prof Lisa Roberts, President and Vice-Chancellor, said: “Everybody at the University of Exeter is thrilled that Tim and Peter have been recognised for their outstanding contributions to climate science in the King's Birthday Honours List. 4/7

“Tim has dedicated his entire career to climate and Earth systems science, leading globally significant research that has been both impactful for individuals, communities and businesses. 6/7

Prof Lenton, Chair in Climate Change and Earth System Science, said: “It was a total surprise and I felt deeply honoured and humbled. Having worked for decades to highlight the risks for all of us from climate tipping points, it means a lot to have that recognised by the government and the King” 2/7

We're delighted to share that 2 of our climate researchers have been honoured in the King’s Birthday List! Prof @coxypm.bsky.social‬ has been appointed CBE for services to science & climate modelling. Prof Tim Lenton has been appointed OBE for services to understanding climate tipping points. 1/7

Most of the human caused climate forcing (that what forces the climate to change) uncertainty is due to the enormous aerosol uncertainty. See grey 90% range around the thick black 'Total anthropogenic' line. Reducing this uncertainty is paramount!

Many care about the actual science, while some pretend to care while openly campaigning against the science. We will all lose when geoengineering will be implemented without the crucial research being done to mitigate risks. Not to mention scapegoating aerosol research. H/t @coxypm.bsky.social

Always wanted to enjoy the beauty of Devon? Keen to talk about climate change 🌏 and solutions 🔌💡? You’ve got one week left to submit your abstract for the Exeter Climate Conference! exeterclimateforum.com/poster-abstr... With @emilywallace.bsky.social, @coxypm.bsky.social, and more

A mind expanding meeting in a wonderful location. Thanks for the invite, Sandy, Colin, and the LEMONTREE team!

There has never been a more important time to discuss climate change, and here is an opportunity to do just that with a brilliant list of speakers and panellists. Register for the Exeter Research Conference before 30th April for early bird rates: exeterclimateforum.com/exeter-clima...
