Climate change is bad.
Our Almost-Apocalyptic Climate Future

"Global investment in green technology for the first three quarters of the year has already surpassed all of 2024. The fortunes of the sector have been in decline for three years, but explosive energy demand fueled by data centers has sparked a reversal."
Global Investors Are Pouring More Money into Climate Tech
Clean energy companies, EV makers and other green firms attracted $56 billion in the first nine months of 2025 — more than in all of 2024.

If MAHA were anything other than dipshit reactionary fantasies & conspiracy theories, it would focus overwhelmingly on air pollution.

"a lot of people assume that there’s really great knowledge and huge due diligence on the chemical safety of these things. But it really isn’t the case.”

We are swimming in a toxic soup of chemicals, + we know very little about what they're doing to us:

More than 100 million ‘novel entity’ chemicals are in circulation, with health impact not widely recognised

Scientists think there's a decent chance that, if global temps rise 2 degrees above pre-industrial levels, it could trigger a cascade of tipping points that further accelerate warming, up to 5 or 6 degrees.

AKA: "A cluster of abrupt shifts occur in ESMs [Earth system models] at 1.5 to 2ºC."
Climate change is not linear: why we need to update the Paris Agreement
For a few years, scientists have been warning that even if we hit Paris targets, we could cross several tipping points that could trigger a cascade into total climate breakdown. ‘A clust...

Just a quick head's up on the global f&%kery that's unfolding.

In the middle of a La Nina, the global surface temperature anomaly year-to-date (Jan. 1 - Feb. 6) for 2025 is currently at 1.74°C above the 1850-1900 IPCC pre-industrial average.

That's 1.74°C.

“One mile on a bike is a $.42 economic gain to society, one mile driving is a $.20 loss.”

“Which means that Copenhagen, a city of 1.2 million people, saves $357 million a year on health costs because something like 80% of its population commutes by bike.” #CityMakingMath

One mile on a bike is a $.42 economic gain to society, one mile driving is a $.20 loss
Copenhagen, the bicycle-friendliest place on the planet, publishes a biannual Bicycle Account, and buried in its pages is a rather astonishing fact.

A gentle reminder that if we miss the 1.5°C target (and we certainly will), the next target is 1.51°C and not 2°C. We need to keep fighting.

Every tonne of CO₂ emitted makes the job of future CO₂ removal harder, and every 0.01°C of temperature increase makes the world more chaotic and dangerous.

When I was in graduate school, we were headed for 4-5°C of warming so this is progress. But it's not enough.
I have a new paper in Dialogues on Climate Change exploring climate outcomes under current policies. I find that we are likely headed toward 2.7C by 2100 (with uncertainties from 1.9C to 3.7C), and that high end emissions scenarios have become much less likely.
