At 5:30pm UK time I will be joining @rogerhallam.com, @fisherdanar.bsky.social, @jeremylent.bsky.social for our panel discussion "Collapse in the 21st century and apocalyptic optimism", part of REV21. Join 👇 events.zoom.us/ejl/AjPpsEFu...

In 2024, renewable energy accounted for over 90% of global power capacity expansion. That is because it makes economic sense. IRENA_DAT_RE_Capacity_Highlights_2025-1.pdf

"As a scientist, I've never had reason to be so concerned as I am today for the future we are facing," states PIK Director Johan Rockström as #COP30 kicks off in Belém, Brazil. The first ever Planetary Science Pavilion, under the mandate from COP30 Brazil, and together with Carlos A. Nobre,... 1/2

The annual 10 new insights in climate science are here! Perhaps the best way to keep up with climate science news of the past year, made for lay people, policy makers and scientists alike with its different levels of detail: from simple tiles to a journal paper. 10insightsclimate.science#explore

Out today in JAMES!! Parameter Estimation in Land Surface Models: Challenges and Opportunities With Data Assimilation and Machine Learning doi.org/10.1029/2024... led by Nina Raoult, Natalie Douglas, @janasknits.bsky.social, @tquaife.bsky.social, me, and an awesome team of folks in the community 1/2

Like most good things, it started with dinner.....

Getting ready for this evenings derailment risk lunch event at @chathamhouse.org.

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

Sunday 7/27 at 10am PT on Climate Chat: @leonsimons.bsky.social interviews U of Exeter climate scientist Peter Cox on Acceleration of Global Warming and Climate Tipping Points. #GlobalWarming @coxypm.bsky.social @bikingmzstacey.bsky.social @radsci.bsky.social youtube.com/live/5rsIoJe...

An excellent @carbonbrief.org article from @robmcsweeney.bsky.social based on discussion at the Global Tipping Points Conference last week. @gsiexeter.bsky.social

Nice article by Oceanographic magazine about our Galapagos plastics research programme. oceanographicmagazine.com/features/inv...

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...

Excellent article on the SeaCURE project. SeaCURE is creating an additional carbon sink by removing CO2 from seawater. @gsiexeter.bsky.social, @plymouthmarine.bsky.social

Steve Kerr wore a Harvard basketball shirt after the Warriors’ win tonight: “Yes, this is me supporting Harvard. Way to go. Way to stand up to the bully.”

AUSTRALIA ENDLESS SUMMER We are entering the second half of the climatological autumn and temperatures are still higher than in mid summer in Southern Australia. Today Cape Willoughby had a minimum temperature of 22.6C, by far its hottest night ever recorded in April.

🌿 Day 1 of the LEMONTREE EEO-LSM workshop kicks off at Dartington Hall, Devon! A group of invited global experts are gathering to brainstorm how Eco-Evolutionary Optimality (EEO) can make land surface models (LSMs) simpler & more robust.

Really exciting climate conference covering key science aspects on the approach to #COP30. Some very high profile speakers, and lots of time for engagement. Me & @richardabetts.bsky.social are running the Extremes, Impacts & Adaptation session 🥵🧊🏥 exeterclimateforum.com @coxypm.bsky.social

I was hoping to avoid this, but I think we may all need to read the Project 2025 Playbook so we can better understand what is being done to us. www.project2025.org/playbook/

Australia’s reefs are on fire 🔥

We are rapidly surpassing 1.5°C of global warming:

I will be on a panel about "communicating with the public, policy makers and climate service providers" on July 2nd. I hope to see you there!

A date for your diaries: 2-4 July, the Exeter Climate Conference "...will present cutting-edge research related to climate change and its impacts, and discuss possible solutions"

Great to see the 'Trex' spin-out now officially launched! Trex and 'Green Future Solutions' @uniofexeternews.bsky.social are working together to help businesses respond to the challenges of climate change.
