Yes, and there’s a lag effect so the temperature will still increase for years after that. However, to be clear, it’s unlikely we get to net zero in 27 years. We haven’t reached any of our goals so far and the goals only get more difficult

Maybe Greenland will finally get populated and maybe people will stop living in hurricane zones

Yes yes the solution here is to physically move hundreds or thousands of years of capital investment, especially forms of capital investment that cannot be moved and are just abandoned/destroyed.

That way we can emit a bunch more to rebuild that already-built infrastructure in a different locale!

My prediction is that geo-engineering will be done when a certain death/disturbance threshold will have been reached (too many climate refugees for example and western world can't achieve a closed border, or too many weather disasters that hit the western world and populations are convinced it is because of global warming). However I don't think we will reach it in the next 5-10 years, but maybe after that period. Al…

Why would you think we have tricks up our sleeves? What’s that mean “geo-engineering will be done when…”

The whole problem is we aren’t capable of doing what we know needs to be done.

The true genocidal policy is to continue dumping CO2 into the atmosphere in increasing amounts. Personally, I feel it is more honest for us to deal with the outcomes of what "we" are doing now, rather than just leaving it for our children to deal with.

The future is fundamentally uncertain. Climate change will be addressed but not by corporate welfare programs like net zero nor by impoverishing rich populations. The idea that the simplistic socio-economic models/pathways are in any way right or predictive was just a fantasy.

This is very wishful thinking. It's like a doc telling you your body is collapsing due to lung cancer, you need to stop smoking, and you answering "the future is fundemantally uncertain, I'm sure something will come along and figure out this cancer for me, got a light?"

The effects of SO2 to the stratosphere are well known and understood, because volcanoes occasionally do just that. Without asking for permission.

In the same volumes and in the same way as we would be doing it?

This article has more detail on how the 2001 Mount Pinatubo eruption lowered temperatures by 0.6°C : https://earthobservatory.nasa.gov/images/1510/global-effects...

There are two mechanisms.

1. The SO₂ combines with water to form aerosol droplets which scatter and absorb incoming sunlight.

2. These droplets break down or drop to Earth over 1-2 years. Which means that if something unforeseen happens it will be gone pretty soon.

Also, while SO₂ in the lower atmosphere causes acid rain, the stratosphere is above all that.

It's odd how everytime somebody mentions slashing oil production by 50 or 75%, people are immediately up in arms. Same for red meat or cheap air travel. Western rich countries have too many really spoiled consumers. It's weird to say, but we should crash the economy if it can slow down climate change. I mean there are plenty people in other parts of the world who don't have such a high standard of living, and it's no…

And what about all the countries that won’t do anything regardless? So we should just tank our own economy while being unable to do anything about our neighbors? It won’t take tanking the economy, it would take world war 3.

It's all making sense now, only WW3 can save us.

Just to be sure, are you proposing killing people today so that they don't die tomorrow?

Because eating less meat, stop taking the plane, reducing our consumption level, replacing cars with bikes and trains and other stuff like that seems radical to you ?

So we can save the world by all becoming Dutch (biking) or Singaporean (public transport) vegans who never travel further than a few 100 km?

Boom, all problems suddenly solved?

You might want to run the numbers on that one some more.

I seem to recall that the first and second IPCC reports (I haven't read the newer ones) indicated that increases would continue for about 200 years, even if emissions went to zero.

The earth is indeed not in thermal equilibrium due to the speed of the recent CO2 increase, so warming would continue if atmospheric CO2 concentration would be held constant . However, atmospheric CO2 concentration would not stay constant after emissions stop. It would go down slowly, mainly because it would continue to dissolve into the oceans. This effect cancels out the above point. Which is why the IPCC says that…

Thank you for the details, I have read similar reports about temperatures not changing that much later on.

One thing to keep in mind though are aerosols, which can bump the temperature up by a 0.5-1 C (afaik) if we stop emitting them.

You realize that would cause countless death _today_ if you don’t replace the oil with something else? People will starve, become homeless, and maybe anarchy will reign. Not just in the developed world but globally.

They may never explicitly admit this, but proponents of "just stop using oil" do intend the mass death outcome. Of course, they have nothing but Good Intentions, these people believe that a steep drop-off in population is inevitable, and they'd rather effect it sooner than later.

It’s extremely depressing that you can’t have more than a couple paragraphs’ discussion without extremism kicking in. No, thinking people shouldn’t drive a 2-ton vehicle for 40km to buy 200g of Wagyu every other day is not the same as planning mass murder. Your comment is inflammatory and delusional.
