The unforeseen positive feedback loops that we will only notice when it's far too late.
We might very well be like Wile E. Coyote, already off the cliff just not realising it yet.
Just like my cartoon!
Preemptive war for diminishing resources.
Wid scale ecological collapse. The ecosystems we have are our life support. They provide all of our food, heavily influence weather patterns, etc. When they go, we go, and we won't be able to out-tech ourselves from the situation. Geopolitical instability rapidly spirals in conjunction with ecological collapse.
I'm surprised to see this relatively low in the list. The biggest problem, IMO, is not that extreme weather events are going to kill people. It's that extreme weather events are going to, at some point, line up badly and wipe out a large amount of food at one time. Add this to the loss of sea life and we simply won't have enough food to feed everyone. Many, many people will die. Many more will try to move.
Looks like Malthusianism is back on the menu!
Geopolitical instability. Collectively, humans are not great at dealing with crisis., so our own collective immaturity will compound any existential crisis. We are the crisis of crisis.
Pandemic is a case in point.
And as for when it will happen, well it started about 2008.

THE YEAR OF MILLENNIAL APOCALYPSE
!ifrickinglovescience !biology !chemistry I'm unironically concerned about climate change as well, but these doomers focus on the most extreme worst-case-scenarios on a very unhealthy way to the point it just discourages any climate action, I don't see much discussion about adaptation neither, not that is a silver bullet but things like more research on GMO heat or drought resistant crops will be necessary and could help with food insecurity. Research on solar geoengineering should also be encouraged.

100% this person either lives in a city, is trying to move into a city, and thinks everyone else should pack themselves into cities too instead moving to some far inland state with vast cheap land and learning how to grow food. If the most ardent doomers are completely unserious about climate change, then why should everyone else take them seriously.

i bet the food shortage will be due to some blight that effects a staple crop like wheat or corn. The resulting famine will kill a few hundred million to a billion people, butt TPTB will blame climaye change as the culprit when its really Ug99

To be fair, farming is hard. If you know close to nothing about it you might even starve lol.

Yeah but wouldn't your own chaz tier garden be better than trying your luck in the post hustle bustle of LA or wherever? At least long term

They would have a higher carbon footprint living in the countryside, the advantage of hustle and bustle life is ironically enough, lower emissions (if the city is not sprawled and has a god public transportation system, so definitely not LA).
I don't think the average redditor is very “green” on that regard though, they consoom so much useless stuff their carbon footprint is probably off the charts.

You really think your small scale homestead larp subsistence farming can grow more calories than mechanized commercial farms? You're dumb as frick. Why? Because shitty small scale farming is how it works in the global south and they ain't doing so great. Literal African tier r-sluration.

They would be growing food just for themselves to survive the for certain climate disaster not for everyone else you r-slur. How do you read try not to die and think it means keep up with the entire industrial revolution.

Yeah, that's what subsistence farming means. It's inefficient as heck. If big farms can't keep up with climate change too feed cities how will you as an individual be able to feed yourself?

The reason big farms would fail is because climate change will result in the loss of infrastructure and manufacturing capabilities and human labor that is required to operate at the insane scale they do now. If climate change disrupts none of the million things necessary for us to operate at the scale we do now, then why is climate change even a problem? Isn't that what the whole thing is about? Or is it just a matter of displacing some people and losing some wildlife?
What an r-slured question. A family feeding themselves do not need tons of manufactured nitrogen fertilizer made from natural gas which itself is extracted and processed in a factory. That's just one of a million other complicated processes big farms depend on to operate how they do now.
Yeah subsistence farming would suck and be work, but believe it or not, there was a time where some families actually had to do that. And if a person genuinely believed that was the only option, perhaps said person would take the steps to prepare for that instead of doing the exact opposite. Why is this simple point made in the original post so hard for you to understand?

You have a fundamental misunderstanding about everything.
Retvrn to guano
Yes, they still do. In the global south, and they will get wiped out first, that's what the redditor is talking about. A tiny farm can't survive 3 bad harvest in a row. Meanwhile in the west there won't be starvation because our food production is efficient and our distribution networks can offset localized adverse weather. Subsistence farming is not an option it's the problem.
Your original point being that climate doomer redditors are all wrong because they are not "moving to some far inland state with vast cheap land and learning how to grow food." The redditor is not doing that because they know it wont work. They know it's r-slurred and foolish. Something only proposed by online contrarian with no knowledge.

Also the first thing lefties will do is confiscate land of homesteaders for factory farms
