This headline could really use the word "hurricane" in it. I had no idea what Otis or Acapulco were, and my initial guess was wildly off: some sort of space probe experienced a catastrophic failure on the way to an asteroid.

"Otis" was also the name of a Kanye West/JayZ song so I was thinking maybe it had something to do with that??

> So how did every reliable model we use miss this? That’s for graduate students and researchers to answer in the coming years, because I have no formal idea. Would love to see followup on this. Wish there were some way to like bookmark or something and come back in a few years.

I'm one of the researchers on a new disease forecasting project, and I'm bookmarking this because we often use hurricane forecasting as an example of a level of accuracy we aspire to, so this is a really interesting breakdown.

The big miss here seems to be that not enough data had been seen yet to even know the envelope of what's possible. Without that there will always be inputs where a model breaks down. Disease modeling is also always going to have to contend with the fact that our historical data was collected when things weren't quite what they are today, for instance population numbers and densities are still entering uncharted territory compared to the past.

I assumed Otis was a indy dev library project and Acapulco to be a code name for a upcoming release.

I thought Otis was half of the adorable Milo and Otis duo and they were having another zany adventure in a 2023 reboot!

First thought: Otis the dog was improperly put into the some kind of vacuum hold on a flight to Acapulco and burst wide open.

Same.

I think we'll see more of this sort of thing. Weather models have been made in a climate somewhat different than the current one and those models are relatively accurate when modeling the past. As more data rolls in about anomalies like this the models will get updated and they'll become more accurate again in specific cases that are outliers right now, but they may end up slightly less accurate overall (due to the i…

I was sure it was some kind of specific machine or package that was destroyed by catastrophic decompression caused by transport mode.

For a weather forecaster this is a really strange take. Anybody who understands what the big words 'climate change' mean, could have predicted this. HAVE predicted this. I personally have predicted this and I'm not even a weather forecaster, I just know what chaos theory is. Adding energy to the system produces a wider range of possible outcomes. This is absolutely one of the possible outcomes. A few degrees less war…

I agree with you and think the downvotes are unfair. That said it doesn't help to just wring our hands about it.(Yes i know you weren't. You were just pointing out it could've been prevented).

> Adding energy to the system Best estimates I've found to date: [ EDIT: 0.6-0.8 ] * Petawatts * of extra energy circulating in the atmosphere as a result of anthropogenic changes to radiative forcing.

With regard to your edit: take a look at the note at the end of the article you are quoting, where the author acknowledges being sloppy with respect to units. Here, he says anthropogenic climate change is heating up the Earth by 300 terawatt-hours per hour (which is, of course - and more simply stated as - a rate of 300 TW or 0.3 PW). Therefore, while it would be correct to say that this results in an extra 0.3 petawatt-hours every hour, this is not the same as nor justifies the statement "...0.3 petawatts of extra energy circulating in the atmosphere as a result of anthropogenic changes...", which is incoherent.

As for "1 order of magnitude (out of 16!)", the "out of 16" is meaningless - the number 16 is merely a consequence of the arbitrary choice of unit size. Your original figure was simply off by a factor of ten, in any units.
