Beyond Zero Emissions

Comments argue that reducing or eliminating CO2 emissions is insufficient to combat climate change, emphasizing the need for active carbon removal, negative emissions, and technologies like capture to address existing atmospheric CO2.

Sadly, stopping emissions isn't enough anymore.

Reducing emissions isn't enough. ZERO emissions isn't enough.

Reducing carbon emissions isn't a solution. We need to go to all the way to zero and then to start carbon capture.That ONLY happens with batteries fusion and AI. We are making progress and as long as the pessimists don't get their way.Ironically people like Greta have had the worst impact on climate. Not just that she flies around the world instead of doing zooms. But that she is all doom and gloom instead of trying to help us progress technology

I don't know why this was downvoted. Along with eliminating emissions, we'll more or less have to find a way to suck out carbon it we're to return to the world we knew.

How expensive is failing to reduce CO2 emissions? That's the current plan.

Stop producing carbon dioxide (and other greenhouse) emissions.

> stop emitting CO2 TODAY, literally.Given that there's no chance at all of this happening, what's Plan B?

It feels like we're at a point where simply dropping emissions down to 0 wouldn't be enough, we need to outright start pulling CO2 out of the atmosphere and have negative emissions. Given the way politics is right now, catastrophe feels inevitable.

A lot of carbon needs to be removed from the atmosphere, something needs to do it at scale. The IPCC says we’ll need global cumulative net-negative emissions of 380 GtCO2 from 2050 to 2100 to return to 1.5°C after a likely overshoot. Focusing solely on emissions reduction will lead us directly to a global warming induced dystopia.

If you really want to curb co2 emissions significantly, the only effective way would be to nuke the USA, Europe, China and sterilize all but 5% of the remaining world population.Anything else is just greenwashing at this point.
