Not really possible. Ultimately it is human demand that is driving climate change. Even if you have a magical technology that cuts all emissions today by 25% -- which would be truly magic -- you only need a 25% growth* in population to offset that and put us back to square one.

At the current rate of 1.2% that's only ~18 years.

The comment you replied to said 'mitigated', not 'solved'. Emissions controls already have, and still can, make enormous impacts on many consumer devices.

Given that emission controls are a whole lot easier to implement than eliminating a huge portion of the world's population, I'd say it's a more realistic goal to pursue.

I wouldn't claim it's difficult per se, we've done it before.

But I do suggest people advocating it join the front of the queue.

(Just because this is hn...)

You'd need a 33% growth in population to offset a 25% reduction in pollution, 100% growth to offset a 50% reduction, and so on.
