Yepp, nothing to worry about here.
It feels like governments have just seen this as a foregone conclusion and are trying to position in an "every person for themselves" kind of deal. Sure, we've finally done something to cut emissions, but it's the slowest possible move they can make.
- I have thought about this for a while now. it just seems that some countries have gamed this out and decided... "sure, 'we' all might die, but you're gonna die first - so screw you!"
  the maxim of "he who dies richest, wins" seems to be the only ideal at play here.
Is it just me, or does anyone else who sees temperatures in degrees Fahrenheit (without a Celsius conversion) in a summary of a scientific report like this just automatically consider it an American fluff piece and click-bait to be ignored?
You should read the actual report https://www.science.org/doi/10.1126/sciadv.adk1189.
It might be my naive reading, but it seems that flooding the ocean with 4-5% of the gulf stream flow with fresh water from glacier melt (I think that's a lot) will cause a shut down in the year 3700 or so. Even I, as a climate change believer, think that's a little too far out there to be considered germane.
- no i am one of those people. No serious science article uses anything but metric.
- Graph A (https://www.science.org/doi/10.1126/sciadv.adk1189) just has model year and not the actual year in the common era. I just assumed all of it was extrapolation from today, which shows a cliff in about 1700 years, so give or take 3700CE.
Actually, probably not
- Oh good. It won't be like a disaster movie because it was never going to. It's still going to be bad, but with less bad acting and more starvation.
Wait, if we have an ice age during global warming... Won't they kinda cancel each other out?
- No, but this kind of reasoning is why it's referred to as climate change now. We don't just get higher temperatures, the defining feature is unpredictable weather.
  
  So does that mean you can't say because we don't know the actual effects? They're unpredictable?
  ...but isn't the main theory about the AMOC shutting down that it may bring on an ice age?
