🎯"Publicity on environmental crises is sometimes even tragicomic. It occurs in a reality without politicians. Discussing climate change and nature loss falls on the shoulders of experts, researchers and laypeople- and it is also on their shoulders to wonder why politicians aren't taking action".

The diagram shows, in black, the national annual distance cycled. On top of this I have drawn the growth rates seen in the City of London and Wilmslow Road in Manchester. A few schemes see a phenominal growth (the heavy lifting) but there aren't enough of them (yet) to affect the national picture.

In Episode 5 of the COPOut Podcast, @amywestervelt.bsky.social explains why, in some ways, it was good that the US skipped COP30 and how it cut back on *some* obstruction and opened up opportunities for future potential climate action. So, even with the failures of #COP30, there is still some hope.

Why is climate action stalling, not ramping up as Earth gets hotter?
As the impact of global warming becomes more obvious, you might expect countries to step up climate action and preparation, but we’re seeing the opposite happen

In the alternative universe where we shrugged it all off as impossible, emissions in the world's power system would be far, far higher.

It is physically impossible that new wind and solar did not crowd out *something else* after they became energised on power grids. New power stations do not induce new demand: grids just do not work like that.
In places where demand has also stagnated or fallen, WS have led to falling fossil use

#1 - deviation from the worst scenarios
If fossil fuel use had grown at the rate it did in the 2000s, global CO2 emissions would be ~5-10 ish gigatonnes (a few percent) higher than they are today
They did not - and they deviated pre-pandemic, too.

Always my fav chart from the GCB, and here's the 2025 update.
It lays out what we've avoided, what we've failed to avoid, and what's at stake if we let the future slip
We are not on a good trajectory, and slipping back into a worse trajectory is always possible. But: we know it bleeds
