It's certainly a strange time to be alive. I was explaining to my child my work in AI, showing him images of himself as a character from his DnD campaign and at the same time am gently introducing him to the increasingly dire state of our climate. For parents of my generation "the talk" is not about sex, it's about the reality that we might not have a future to offer our children. It feels like I am very literally li…

What I find strange is that people are actively building a zoo for themselves. The population could have been very happy and rich with around 1 billion people — less garbage, less pollution, less extinction of species, less monocultures and farms, more biodiversity, sustainable resources, and not as much pressure on ecosystems. But we live on an exological credit card.

If this world with a billion people existed, most likely (7/8th chance) you wouldn't exist. How does never existing make you feel? Unless in this fantasy you'd survive and enjoy the extra resources which comes off as extremely selfish to me.

The warming of the oceans could lead to the following consequences: - Coral reef collapse and loss of marine biodiversity. - Accelerated sea-level rise, resulting in coastal flooding and displacement of populations. - Ocean acidification, harming shell-forming organisms and marine ecosystems. - Disruption of ocean currents, leading to altered weather patterns and increased extreme weather events, potentially causing…

ME: "Release of hydrogen sulfide (H2S) from warming ocean sediments and decaying organic matter, a potential extinction event." Is this a realistic possibility? GPT-4: The phenomenon you're describing is associated with an event referred to as a "Canfield Ocean" or "Strangelove Ocean." The hypothesis is named after paleoceanographer Donald Canfield, who proposed that several mass extinctions in Earth's history might…

We simply don't know. I recommend Peter Ward's video for more info.

"The impacts of the decline and potential shutdown of the AMOC could include losses in agricultural output, ecosystem changes, and the triggering of other climate tipping points."

https://en.wikipedia.org/wiki/Atlantic_meridional_overturnin...

"The possibility that the AMOC is a bistable system (which is either "on" or "off") and could collapse suddenly has been a topic of scientific discussion for a long time."

https://www.livescience.com/gulf-stream-slowing-climate-chan... (2021)

"The Gulf Stream — one of Earth's major climate-regulating ocean currents — is moving slower than it has in thousands of years, a new study suggests. Human-induced climate change is largely to blame."

"If the Gulf Stream crosses its tipping point, it will continue to weaken even if we have managed to stop global warming," Caesar told Live Science. "Afterwards, it will slow down by a lot, coming close to a complete shutdown of the circulation."

I see 3 semi-distinct bands in the data, where there are dense clusters of lines, and gaps in between where the lines are a bit more sparse. It looks to me like the line jumps from the bottom band to the middle band in 1997, then back down, then up again in 2001, and then stays there until 2014/2015 when it jumps up a second time. You can see them better if you remove the mean/+2sigma/-2sigma lines. I wonder the reas…

The oceans normally undergo a cycle of patterns in ocean currents which also manifest surface temperature warming and cooling. You've probably heard "El Niño" and "La Niña" during weather forecasts.

The cycle is very irregular and I doubt we have good prediction models for it. However, the observations of the ocean currents line up very well with ocean surface temperature readings.

On it's own, the ENSO cycle would not cause an overall trend of warming. However, it is very capable of being the cause of the "bands in the data" that you noticed.

Every society is 3 meals away from total chaos.

What provides those meals is a system built on top of topsoil, fresh water, fish, oil, pollinators, and atmospheric conditions of humidity, temperature, precipitation, etc. And the absence of pollution.

Topsoil is not dirt, it's an habitat for organisms that make soil fertile. It takes many years to regenerate 1 inch of topsoil. Agriculture consumes topsoil faster than it regenerates.

Fresh water is water with low saline content. Desalination does not work at scale, and if it did, it would still make food prices rise. Fresh water is only 2.5% of Earth's water. Rivers are being polluted, groundwater is being pumped faster than it is replenished. Rainwater is not enough to sustain agriculture. https://www.youtube.com/watch?v=RjsThobgq7Q

Sustainable fishing requires harvesting only fish above reproductive age. Fisheries do not care about this. https://en.wikipedia.org/wiki/Trawling

Pollinators everywhere are dying due to habitat destruction and products used in agriculture.

And on top of that we are changing the composition of the atmosphere via pollution, causing it to trap more heat, and causing oceans to become acidic, which in turn causes climate to behave differently in ways that affect agriculture.

In short, it's an ecocide. We are in the middle of an extinction event: the Anthropocene extinction, an extinction event caused by humans. Animals above certain weight are dying and that is an excellent indicator that we are next in line.

Each human has a stomach which is a chemical reactor, and food is its fuel. And as more humans are added to the population the rate at which we process (destroy) the environment accelerates. We are already beyond the point of sustainability and heading towards a predictable collapse.

Putting a single-use plastic container into a recycle bin won't do shit for the environment. Our civilization is just a giant ant death circle following each other's pheromone trails until we collapse collectively.

Not much can be done other than downscale your lifestyle, avoid traveling, go zero waste, stop buying from ecocidal corporations. But this will only delay the inevitable: more environmental impact, and ultimately, global conflict.

Remove the 3 meals from people's tables, and you'll get conflict over the resources that are left. The strategic pieces in this conflict are already being placed on the board.

Earlier quoted context omitted.

Another feature of human end of the world predictions is its always different this time.

Okay. So make the equation equate. How could humanity make most of the planet uninhabitable 1000 years ago?

Lots of reasons, by having sex or praying the wrong way were common. The wrong way being the way some other out group does it. Now we can end the world by doing things like driving the wrong kind of car (but not by flying around the world to "broaden the mind" as in group members like to do that). You can even buy indulgences.

People can have children below the replacement rate

They already do, in tons of countries

It might take care of itself, if not for AI and nukes humanity could be fine. But they just can’t resist, humanity seems to be acting like a rapacious child because of competition across countries.

As for your question… look ul the Doomsday Argument. 7% of all people who ever existed are alive today. If the population constantly increases then given the fact that you are alive means you’re more than likely living in the last days before a major population crash. The only question is what will be behind it — birth control or some ecosystem collapse?

Release of methane permafrost

https://en.wikipedia.org/wiki/Clathrate_gun_hypothesis

Not all ice is made from water. Some ice is frozen methane. If you melt it, you'll release methane.

Atmospheric methane is good a trapping heat (aka greenhouse gas). That heat warms the atmosphere, which melts more ice, which includes methane ice, which in turn releases methane, that heats the atmosphere more.

In this way you have a self-reinforcing effect where before you know it you have an exponential release of methane/exponential temperature increase and an extinction event like the Permian–Triassic one.

I find myself losing hope for humanity when I observe a significant portion of society in Germany, for instance, either voting for or intending to vote for a party known as the 'Alternative für Deutschland'. This party is primarily defined by what it opposes. Its supporters are often frustrated and resistant to evidence that their meat consumption contributes to climate change, or that fossil fuels exacerbate this gl…

Sounds like the MAGA movement in the United States. I share your sentiment of losing hope.
