There's clearly some bad news here, too.
But, for example, natural gas won't be ascendant for much longer, or stay there through the end of the century.
The forces driving down climate tech costs are just too strong.

Compare that to this collection of paths, pulling from IPCC, IEA, and Shell(!).

But more importantly, look at *all* the others, including Shell's most pessimistic.

This graph, based on ClimateActionTracker.org's latest projections, has global CO₂ₑ emissions peak right about now-ish and then decline by 2100.
Good, but look at the slope of the decline. It's basically a slow linear decline.
That's...not how the world works.

Holy wow, +3.5 ppm CO₂ last year, up from +2.4 ppm average the past decade, and +0.6 ppm in the 1960s.
It gets scarier the closer you look at it. All this is a stress test for the planet, and it's buckling.
Two big reasons for the massive increase: wildfires, and the ocean sinks are shutting down.

Coal is losing to solar + storage on economics alone, necessitating Trumpian stay-open orders.
But coal dominates iron production, and will do so for a long time—despite justified excitement about the Stegras and Electras.

Austrian electricity is 90% renewable. The other 10%? Gas.
Last week, Austria celebrated no longer importing any Russian gas! 🎉
Now the warning: the EU exiting Russian gas means higher prices in Austria. 📈
Yup, using *any* gas means dependency on geopolitical vagaries!
The one fix: get off gas!

At this point this is no longer just about wind or renewables, this is about basic investment certainty.
Lack thereof is why investors demand 20+% return for the same investment in Egypt that gets 6% return in Germany (and yes the US is already at 7 or 8% in this calc)

Gondola up the Zugspitze, marvel of German engineering 🚠
Also witness the massive parking lot at the bottom. Yes, there's an easy train from Munich. Yes, there's the beautiful, almost entirely undeveloped Eidsee. But no, asking Germans to take the train to avoid a 500-car lot would be too much. 😔

Adam Smith still gets invoked by the odd "conservative" think tank, pretending that he'd have signed on to their "pro market" policies.
Smith was pro banking regulation, pro firewalls (the pre-Internet kind), and yes, he'd have been pro climate action.

But what this graph on rooftop solar also shows is just how much *utility-scale* solar has entered the Texas grid, lowering average power prices so much, that rooftop payback periods in Texas are now longer than elsewhere.
