White House is pushing ahead research to cool Earth by reflecting back sunlight

Many advanced nations have already seen pretty significant emissions declines, and this is robust even when you factor in offshoring manufacturing. Many of the huge declines in renewable energy production prices haven’t kicked in yet, so we’re likely to see lots more. Getting to net zero isn’t impossible. The problem is that we may get there when it’s too late.

Then the GP suggestion seems to have a role again - if net zero emissions is not enough, carbon capturing is needed to mitigate previous emissions.

The two are not mutually exclusive.

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.
