All of these things are part of net zero (and beyond). The problem is that we may already have kicked off a warming/methane/cloud feedback loop (there are several) and so getting carbon emissions down in the future isn’t going to be enough to fix it. These geoengineering solutions scare the life out of me, but they may (soon) be our only option for surviving this.
