There is no single “correct” path to decarbonise. There are six trillion. Our new paper in Science puts 36 climate solutions into one common unit, so you can build your own pathways. Paper: doi.org/10.1126/scie... App: climatewedges.com What would your pathway look like?
My global decarbonisation pathway, built on www.climatewedges.com

It deploys 20 wedges to limit global warming to 1.5 degrees.An infographic showing the 36 strategies that can deliver at least a wedge of mitigation.  It explains the scale of deployment each one needs, across the electricity, industry, buildings, transport, and land use sectors.

It was very interesting developing these short @apolitical.bsky.social courses for civil servants on electricity grids, featuring a range of Imperial experts, including @iain-staffell.bsky.social. Any non-experts in government looking to learn about future electricity networks, check these out! 👇

Do climate conferences actually achieve anything? A lot of people have strong opinions, but we wanted measurements, so we look at how the stock market moves during yearly international meetings called COPs – explanation below, or read the paper here: iopscience.iop.org/article/10.1...

In a UN speech today, President Trump said that "all of these [climate] predictions were wrong". Back in 2019 I led a research effort to digitize old climate model projections and assess how well they did. Turns out they got future warming pretty spot on!

In a new study, we estimate how much geological CO2 storage capacity would be available when considering social, environmental, seismic and other risks. Lead author @gidden.bsky.social wrote an extensive 🧵on the work 👇

Sharing our new paper in #NatureCommunications on solar-based mini-grids interconnecting with national grids can boost reliability, cut costs + emissions, and reduce the risk of asset stranding, co-led by @benwinchester.bsky.social & with @shivmit.bsky.social, + others! @natureportfolio.nature.com

Spogomi - the sport of competitive litter picking. I had no idea this was a thing, but what great idea by the Japanese to help clear up parks & public spaces. In Hackney Marshes this weekend! www.theguardian.com/environment/...

A new International Energy Agency (IEA) assessment of the lifecycle emissions of coal vs LNG shows that LNG only offers a pitiful reduction in emissions compared to coal Gas talking points present themselves as a 'climate solution', but they're a climate cause www.iea.org/reports/asse...

We have been banging on about it for more than 10 years, but anyway: 2014: www.nature.com/articles/ncl... 2016: www.science.org/doi/10.1126/... (and loads of papers ever since) Of course, some DACCS / BECCS / etc is quite reasonable, the scale (level and growth) is the issue.

Keeping 1.5C as a goal isn't fantastical, it's the only acceptable option. Moving goalposts allows indefinite broken promises. A fixed goal highlights urgent reality: every extra tonne of CO2 we emit will need to be removed to get back to that agreed level The longer we stall, the harder it gets.
