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?

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! 👇

Built for public servants at any level working across the energy ecosystem, we've partnered with @apolitical.bsky.social to create two practical self-paced courses that teach: ⚡How electricity systems work ow.ly/3r8s50YcbSp 🔌How to future-proof electricity grids ow.ly/1ciR50YcbSL Sign-up today ✍️

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 👇

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/...

Solar PV made up 81% of new power capacity in 2024, putting it on track to meet the global goal of tripling renewable capacity by 2030. Check out the latest report from REN21 #GSR2025 https://www.ren21.net/renewables-2025-global-status-report-global-overview/

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...

⚠️ Scientists find three years left of remaining carbon budget for 1.5°C The remaining carbon budget for 1.5°C will be exhausted in a little more than 3 years at current levels of CO2 emissions, according to the latest Indicators of Global Climate Change study published today🧵 📒 buff.ly/0BQAsfp

✈️Tourism carbon emissions: new study in Nature Comms. 🔴Emissions from tourism grew 2x the rate of the wider economy from 2009-2019. 🔴Tourism made up 8.8% of global emissions in 2019. 🔴The 20 highest-emitting countries generated 75% of tourism emissions.

If a city increased its road capacity by 10% then driving in that city went up by 10%.” Still one of the best articles on why building bigger roads leads to more driving.

Many modeling studies depend on direct air capture (DAC) in their 1.5°C stabilization scenarios, but they rely on overly optimistic assumptions regarding the cost and scaling of DAC systems. This leads to highly misleading results that impact the ability to reach climate stabilization goals.

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.

Joeri Rogelj@joerirogelj.bsky.social · 2y ago

Climate action is falling terribly short Time to bury the 1.5C goal? Absolutely not - why the 1.5 goal must prevail (even when global warming exceeds 1.5C) My opinion for Project Syndicate 👇 www.project-syndicate.org/commentary/a...
