Hi everyone 👋
Sam Jackson here, Director of Climate Science and Impact at Ecologi - ecologi.com
I will be posting about climate change, nature and net-zero. Also covering our work at Ecologi to help businesses accelerate climate action.
(And probably some personal posts about books and nature!)

Ok I see news reports lacking clarity. The two roadmaps announced by the COP30 Brazilian presidency on halting deforestation and transitioning away from fossil fuels are voluntary in nature. They were announced at the closing plenary without gavelling. They do not constitute a COP decision

"Too little was done too late”: New commentary with PIK director Johan Rockström warns of rising planetary risks after a missed decade of action. Climate & biosphere pressures keep increasing, but stabilising the Earth system is still within reach.

Scientists at the Planetary Science Pavilion on #COP30: Most of the 1.5°C CO₂ budget is gone. 2025 emissions still rising. ~4 years of budget left. We need 5% cuts yearly & roadmap to phase out fossil fuels. Science must stay in the text, not be scrubbed.

The thing I despise is inhumanity. It’s not really a political position, it’s an existential one. But if your political party manoeuvres itself into a place where it practises and promotes inhumanity, I will despise you.

Another dataset confirms that last month was the warmest October on record in the #Arctic. The previous record was 2024. This is already a month with a very large increasing temperature trend (i.e., Arctic amplification). Not good.

A writer in Ohio calls the existential threat of climate change “a no-brainer.” A radiologist in Scotland describes it as “the greatest hazard to human health in history.” A finance worker, who lost their home in a California wildfire, says, “We have to hold the fossil fuel industry accountable.” 🧵

I'll cautiously say I've noticed more skepticism about AI in the corporate world and it's mostly because people's coworkers are creating extra work for them. They don't have the vocabulary to describe it yet but it's basically the "Why should I read what you couldn't be bothered to write" thing

Both sides of a conflict are calling each other evil and corrupt, rendering me, a humble journalist, helpless to discern the truth. Best I can do is let you know that both sides are in fact saying those things. Hope this helps

This is simply untenable. There is no way forward with media and political classes captured by the right. Every time someone commits a crime you have to pray it's not an undesirable or it's purge time, then when it turns out to be themselves again they just shrug and wait for the next one.

As someone who reads and adores Norse history & mythology, I am gutted that this is yet another thing these losers are trying to appropriate for their own fascist ends.
Also: “we have the watch” is literally from Game of Thrones.
Governing a country (or running the FBI) matters, it’s not cosplay.
