The report does outline some all important positive signs: e.g. Morocco committed to phase out coal, Colombia has a moratorium on new oil and gas exploration. The energy transition is accelerating

But they say it how it is - we are in trouble

A LOT of work goes into these warming estimates. Bravo @climateactiontracker.org

Sadly governments are not putting in the same amount of work. They're cooking the planet.

Rescuing 1.5°C: new evidence on the highest possible ambition to… This study shows that, even after years of insufficient action, the world can still return to well below 1.5°C of warming this century if countries pursue the “highest possible ambition” in climate ac...

Check out the IEA NZE here tinyurl.com/2ctf7mrx (but ignore the unrealistic-zombie-nightmare (CPS) scenario)

For a nice comparison, see this new high ambition pathway by @climateanalytics.org and the REMIND team at @pik-potsdam.bsky.social - tinyurl.com/y9m8z8jk

Despite this, we've fallen behind the original NZE. The updated NZE shows emissions falling immediately to limit peak warming to ~1.7°C, with deep cuts and carbon removal needed to then pull back to 1.5°C.

Another 5 years of delay would add a further 0.1°C to peak warming - we cannot afford this

The IEA's first net zero scenario (NZE), published in 2021, showed emissions peaking immediately and falling to net zero by 2050.

Today they published an update. Although we are behind on most things, solar and wind deployment moved EVEN FASTER than the first NZE suggested. A little ray of hope.

Really worth a read!

Episode 2: Highest Possible Ambition under Overshoot with Joeri Rogelj

In the lead up to the Overshoot Conference @iiasa.ac.at Sep 30-Oct 2, the organizers had a fantastic nerdy idea to get the leading experts in their fields share their perspectives on the key themes. Highly recommend for your daily commute, background to cooking etc.: open.spotify.com/show/5MpXqh1...

With sufficient data in for July, the year-to-date estimate of India's fossil CO₂ emissions is now +0.3%.

'Whether you win or lose, some fights are worth fighting': The largest ever climate case's unlikely origins The UN world court is coming to a conclusion on its largest ever case, which considers states' legal responsibilities to tackle climate change. It all began with a bold student idea.

The ICJ gave a remarkably assertive ruling on the obligations of states in tackling climate change yesterday.

This story about the grassroots efforts by Pacific islanders to make it happen is really worth a read.

I’ve started my train-bike-ferry tour from Berlin to Leeds for Scenarios Forum! @priestleycentre.bsky.social

So far so good! The train to Amsterdam was long and delayed, but the ride to Rotterdam was beautiful 🚲☀️and I enjoyed calm seas and a distant offshore wind farm on the ferry to Hull 🌬️🚢

Big climate litigation news today on Lliuya v. RWE in Germany. Court rules that major emitters may be held accountable under (German) civil law for climate damages internationally. This has far reaching implications. 1/
