As in “We haven’t cut emissions to zero yet.” We can, and will. It’s a question of whether we do it quickly enough to preserve a civilization-supporting climate.
We should probably start with reducing the rate of increase first. Then talk about reducing emissions per year. As for zero emissions, I fail to see how we have a civilization of any sort without some emissions. Maybe that’s the point. Was “Net Zero” a hidden word for collapse all along?
Emissions have been falling in the US and EU since ~2005 or so, and look to be about to start falling in China, which means that they’ll be falling worldwide after this year.
But…they’ll likely be falling slowly, rather than rapidly, which is a problem.
That’s a really hopeful reading of that chart. What I see in that chart is that even a year or two of falling emissions could quickly be wiped away. Just look at 2022.
