Counter-intuitively, this is an optimistic post.

A month ago, the U.N. Intergovernmental Panel on Climate Change (IPCC) published a new report. Amongst a long list of bad news, the report states that our CO2 emissions "would have to be on an extremely steep downward path by 2030 to either hold the world entirely below 1.5 degrees Celsius, or allow only a brief “overshoot” in temperatures." This is more pessimistic news that many had expected.

Unfortunately, it's not entirely surprising. Three years ago, in Opti-pessi-mistic tweetstorm on climate change, I wrote "It’s a public secret that things are way worse than we think. But scientists can’t say so else they would lose all credibility. Catch 22."

To expand on this point — for a long time, if you were a climate scientist, you needed to walk a fine line. On the one hand, sound alarmist enough to make people care and take this seriously. On the other hand, you couldn't say things that were too pessimistic — for the fear of creating a helpless reaction of "Well, if it's so bad, we can't do anything anyway, so why bother." 

I fear that this dynamic caused a significant under-statement of how bad the situation is. I suspect that we're finally getting to the stage when the science cannot be played down any further, and we may see all the bad news start coming out at once. The IPCC report was probably just the first drop.

I don't think that's necessarily a bad thing though. Over the last twenty years, we've proven that if predictions are just moderately bad or we have "a lot of time", we won't do enough to reduce emissions. Most countries, organizations, and individuals need to face the true magnitude of the crisis to change their behavior. So it's good to see reality come out into the open.

This will be an incredibly difficult fight, but there are signs that make me optimistic — both geo-engineering in general, and CO2 capture in particular.

Much has been written [1] about the American healthcare system and why it fails us, especially for those not in the top 10% [2]. I'm by no means an expert, but over the years, I've often come back to a story I heard from someone at a dinner party a few years ago. We'll call him Paul.

Paul's girlfriend, Tina, needed to get a standard panel of blood tests. She found a clinic, went in, and got her tests done. Two weeks later, she received her results, together with a bill for $5,000.

As it turns out, Tina made a mistake and went to an out-of-network clinic. Panicked, she called her insurance company. Unsurprisingly, they weren't very helpful. Despite her pleading, she was told their maximum was $1,500, that her reimbursement check was in the mail, and that's all they could do.

As a last-ditch effort, Tina called the receptionist at the clinic that did her bloodwork. She explained her situation, not expecting much. Without taking a breath, or even passing Tina to accounting, the receptionist immediately offered something unexpected. "If you can pay by credit card right now, we can settle everything for $500."

Shocked, but not willing to risk her good fortune, Tina took the offer and paid over the phone. A few days later, the $1,500 reimbursement check from her insurance provider arrived. Tina cashed the check, and went shopping.

I don't approve of Tina's ethics, but I thought the story explained much about why our healthcare is so expensive. We've created a system where every party is incentivized to use opaqueness and lack of transparency against everyone else.

Over the last few years, I've often wondered about the right heuristic for deciding which hobbies to pursue.

"Enjoyment" or "passion" get thrown around, but I've found it's not that simple. Some hobbies create a lot of joy/pleasure upfront, but that enjoyment doesn't necessarily increase with time (e.g. fine dining [1]). Others aren't necessarily fun when you start learning them, but you can get better for years and years, and the enjoyment keeps increasing, too (e.g. tennis).

Besides, there are only 24 hours in a day.

Two years ago, I came up with a somewhat unusual metric, but I've found myself coming back to it ever since. 

The heuristic is pretty simple: "When doing thing __X___, how easily, and how long for, do I forget that I have a smartphone in my pocket/backpack/car?"

(Winner so far: fly fishing.)

[1] I realize many foodies will disagree. I believe they enjoy each meal more as their knowledge increases and palate gets more educated. It just doesn't work that way for me.

Walk into the average pharmacy, especially in the US/UK.

Half the aisles contain addictive stuff that makes you sick. The other half carry addictive stuff that mitigates just enough of the symptoms to keep you consuming more of the former.

In many cases, the same company produces goods of both types.

This is a bit exaggerated.

Unfortunately, it's also mostly true.

Two and a half years ago, I wrote down my best guess for what will happen regarding climate change:

  1. We should try to minimize CO2 emissions.
  2. But, given the incentive structure, we'll most likely fail to eliminate enough, quickly enough.
  3. Since cost of geo-engineering the atmosphere to let through less sunshine is low, at least one actor (private or government entity) will most likely attempt to cool down the planet, at least temporarily ("put sunglasses on the planet").

A month ago, some new data and claims came out on CO2 capture technologies, suggesting that the cost of removing a ton of CO2 could be closer to $100-200, rather than the $600 we had long thought was the minimum cost we could achieve.

$100-$200/ton is still more expensive than what it costs us to reduce our emissions by a ton (~$80). So most people dismissed the new findings as interesting, but not particularly impactful.

They're missing the point though. As Noah Smith articulated in his excellent tweet storm, CO2 Capture gets cheaper with scale, whereas the cost of reducing our emissions gets exponentially more expensive with every ton.

I'm cautiously optimistic about the potential of CO2 Capture — as a research field, and maybe even as an industry.
