Re-making coal!
Just wait a 100 million years
When it comes to climate, doomism is a western luxury because we’re less affected.
The future is what we make of it… the longer we wait to act the more severe the consequences of climate change will be
Not every day you break a word record. But for me this was yesterday!! We ran the world’s deepest marathon.
An impressive immersion in a working mine
Why not?

Weird…
Does that work?

And here is the first article!!
Some learnings from my climate journey…

Launching my Substack today !!
This will build on the content I am sharing regularly on LinkedIn and provide deeper thoughts on the fast changing space of climate and deep tech.

2 weeks to go before the World’s deepest marathon- 1.4 km below the surface.
This is going to be a world record if we make it and this is also for charity. Any donation is appreciated

100 days to go !!!! 🏃♂️
With a group of 60 people, we'll attempt a record-breaking marathon, 1,120m below sea level in Boliden's Garpenberg mine in Sweden.
This is done to raise money for 2 charities and change discussions around mining (critical for energy...)
Consider donating
I know. The irony is that we are visiting with a rental car which is… electric.
I am glad to know it can’t go on highways
My family is against electric cars…
Have been listening to all the usual misinformation arguments for 90 minutes and people wonder why I am quiet…
The doctor’s waiting room has some great reading 😎

A bit of a plug, but quite proud of that interview in @newscientist.com about the work we do at the Foundation.
You'll also find how I deal with optimism/pessimism ;-)
Thanks @tinymaddie.bsky.social for the great work

People often wonder how climate activists stay positive. I feel like I can get behind this method from @gregdt.bsky.social

In 2023, the world produced 4.5 billion tons of oil, 9 billion tons of coal, and 2.5 billion tons of fossil gas (lnkd.in/eUUxhqc5). The combustion of which released about 37 billion tons of CO2 into the atmosphere (lnkd.in/e5t6bdhR)

Proud to have contributed to the launch panel of the Make Science Great Again panel by @wedonthavetime.bsky.social
Knowledge is power. Defending science is critical for well functioning societies
Great Sankey diagram about the global material flows of plastics in 2022. About 400 million tons produced.
98% of the feedstock were fossil- coal accounts for 44% and oil for 40%

L’energie c’est simple et complexe
J’ai eu le plaisir de discuter énergie avec Vinz Kanté sur sa chaîne Limit. On part des bases pour discuter de nombreux aspects de la decarbonation.
Bonne écoute

Il est sorti!!!!
Une vision complete de la decarbonation des transports passant par l'énergie, l'aménagement des territoires, les politiques publiques et l'économie.
Fier d'avoir pu contribuer a ce travail !

Last year the share of low carbon electricity in the global mix reached 40% thanks for data deployment of renewables.
But fossil production also increased albeit slower.

Interesting point. As most energy systems still rely heavily on fossil fuels it is hard to decouple both- but hopefully we will at some point.
Thanks

Energy security will become the highest priority for the transformation of the energy system- climate will come second at best.
This graph shows how the US, EU, China fare on that metric. The US went from a major oil importer to a next exporter (it still imports a lot).
Geothermal is having a moment. Glad to support with QCF a study on the Future of Geothermal in the UK led by Project Innerspace.
Listen to that episode of Cleaning Up to know more about what’s new in that field m.youtube.com/watch?v=n3I2...
Given that the energy transition seems to be entering a bumpy phase I have decided to get back to the basics and invest in a coal steam engine
😅
What is happening to the US science system is dramatic. De-funding science, taking references to climate change off federal websites etc, won’t change the reality of facts.
And cutting your main innovation engine is just sabotage…
