Reversing climate change. Carbon removal, direct air capture, biochar, rock weathering, planetary cooling, sun reflection, the works.
I'm the co-founder of AirMiners (http://airminers.com): the place for scientists, entrepreneurs, and engineers mining carbon from the air.
227 startup graduates from our accelerator have raised $250M of venture capital and grants, and sold more than $100M of carbon removal credits.

From what I can see the only thing that durably keeps me on iOS at this point is Facetime.
(Siri AI is bad. Lots of "Did you mean". I'm back on Siri Classic now.)
Zeke's multi-year comparison chart (#1) ends in December, but the forecast chart does show through July 2027 all the different models. I don't see any modeling a double peak, though that NASA-GEOS-S2S-2 line peaks in February.
25 years of data, any other impacts you've seen from carbon dioxide rising? (~370 ppm in 2001 to 420 ppm this year)
But this mental model loses the most important feature of the climate system.
It's not a dimmer switch. It's more like an ON / OFF switch.
We live in a stable climate today. Things are getting a little warmer. And we see some weird things. But still, even at a little warmer, we are in the same stable climate system, just a little warmer or cooler.
However, if we flip to "OFF" on a stable climate by getting a lot warmer, our climate system moves to a chaotic state unlike anything we've ever known in human history.

And their perspectives on their process here: https://frontierclimate.com/pathway
Let's say I take it that whatever post you're referencing is slimy, built on disaster capitalism, and downright bad. And your being jaded is totally understandable.
To that I remind you: "All that is necessary for evil to succeed is for good people to do nothing"
What could you do to do drive the world in a different direction? (see my other posts for projects if you want help out with our El Niño Ready dashboard)
You can find examples here on Frontier's site of companies that are taking biomass (plant stuff like tree waste) and sequestering it in mines or other storage deep underground.
When thinking about sucking carbon from the sky, I find it useful to separate how I think about grabbing on to carbon dioxide from how to store carbon dioxide, rather than thinking of it as one step. I find it's easy to get lost and either over or undervalue things otherwise.
Plants and trees are excellent at grabbing on, for example, and with a good process they can lead to very cheap methods to store/remove carbon dioxide for a thousand years.
Marine carbon removal: 16
Biomass carbon removal & storage: 13
Direct air capture: 12
Field weathering: 8
Mineralization: 8
And, at the same time, polluting the climate makes the climate system far more susceptible to flipping to a chaotic system unknown to humanity.
As Stewart Brand says, "We are as gods and might as well get good at it."
Not sure why folks downvoted you.
We're way off the charts already.
Stripe's climate scientist Zeke Hausfather came to AirMiners to tell us about what's next: https://www.youtube.com/watch?v=0-Xu_H3Wo8o
In 1877, 50 million people starved to death from El Niño. The charts are looking far worse in 2026 (thankfully our supply chains and infrastructure are much better today)
We can't stop the storms but we can work to avert the impacts and save lives.
We're building tools at: https://elninoready.earth
One thing we need help with is how to provide detailed recommendations per city/address to people based on historical El Niños. What are local emergency notification services, where can you get free sandbags, should you expect floods, droughts, tornadoes? What backup services are there if 911 goes down? (If you have ideas, here's our github: https://github.com/titojankowski/elninoready)
Our first step is bringing together people at New York Climate Week so that's what's up on the site right now.
AMA
What's shifted in the other direction is that it's getting too damn hot here and some people are starting to notice.
We have a partial list...could use some help!
One thing we need help with today is finding any other events at New York Climate Week that are about El Niño to feature on our site: https://elninoready.earth/

(tldr properties of how our atmosphere works and the pollution we put in it ends up being a laser beam at the same height as glaciers form)

So no, switching everyone to a CO2 heat pump will not magically store all our emissions.
ssearyus: At the risk of being immediately downvoted, let me point out that a 250ppm CO2 level is borderline disastrous for plant life -- at 180ppm, plants would starve globally. The increased CO2 levels in recent years (slightly added to by human activities) is immensely helpful for drought-resistance, as stomata do not then need to open as much to get sufficient CO2 with the result that they transpire less water. The above, and the fact the by far the most important GHG in the atmosphere is water vapor (CO2 is comparatively a rounding error) should give reasonable people pause for thought.
My response: I think there's something you're trying to say, but it doesn't come through clearly in these many points.
- 250ppm is not disastrous for plant life. That's around preindustrial levels of CO2 (280ppm) and plants did just fine
- What do you mean by "starve" here regarding 180ppm?
- And why are you talking about 250ppm and 180ppm specifically? No one is talking about 250ppm or 180ppm as targets (or maybe you are?)
- Water vapor is indeed a greenhouse gas, and contributes to warming. But it's best thought as an accelerant. Warmer temperatures bring more water vapor bring higher temperatures, bring more water vapor etc etc. The rise of carbon dioxide in the atmosphere is so important because it trigger in many ways a feedback loop, one of which is rise in water vapor as a greenhouse gas. The feedback loop caused by temperature/water vapor is one of the reasons we need to be very careful with our human-made emissions.
- "CO2 is comparatively a rounding error": Whether by mass or volume, CO2 is not a rounding error by comparison to water vapor. There's roughly 4 to 6 times the amount of water vapor as CO2. I wouldn't call 25% a rounding error. Maybe there's something I missed here.
- And when you say water vapor is "by far the most important GHG in the atmosphere", does that mean you're working on lowering water vapor levels in the atmosphere? Or what are you working on regarding solving for this? Maybe something with airplane cloud formation trapping heat?
El Niño this year is going to be especially crazy, worst in human history by a large margin looks like. I'm putting together El Niño Climate Week to work on averting the worst impacts. It's a good opportunity to move the conversation forward about how our climate is changing very quickly.
My projects tend to be pretty good schelling points for people that like to take action, in case you're finding the comments here frustrating ("I'm not surprised", "we just need to X", "we're doomed", "it will be fine", etc etc etc)
Decile 10 (richest): ~48%
Decile 9: ~15%
Decile 8: ~10%
Decile 7: ~8%
Decile 6: ~6%
Deciles 1 through 5 combined: ~12%, so about 1 to 3% each
I wouldn't necessarily focus on it, but it's something good for your mental model of how to solve the challenge.
The reason I say I wouldn't focus on it is I'm coming around to the idea that "carbon footprint" is effectively a marketing campaign brought on by oil companies to have us focus our individual power where it has the lowest leverage - sorting trash, our own individual emissions, etc, Instead of mobilizing hundreds, thousands, millions, and billions of people to change policy and technology.

What's needed now is something like a "carbon wave", where you evaluate your impact by how quickly you move the entire world forward.
There's a new book on this to that just arrived to me last week: https://www.barnesandnoble.com/w/the-carbon-wave-leah-c-stok...
