> A halving of population would do nothing on any time scale. A small blip easily recovered by reproduction.

The population was half of 2020 in 1973 (1). Emissions were also half of now back then (2). That’s nearly 30 years of runway that Thano’s solution would provide. With today’s technology and rapid iteration, we could definitely do something better for climate change.

I’m not endorsing the method, but merely disagreeing with your assertion.
