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:

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.

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.

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

⚠️ 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🧵

"According to the International Energy Agency, in 2023 the growth in big cars increased oil consumption worldwide by 500,000 barrels per day and generated 20 percent of the entire global increase in manmade CO2." Via @davidzipper.bsky.social

✈️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.

“We found there’s this perfect one-to-one relationship. 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.

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.
