This would only give a 30yr break on just one factor of the ecological collapse. I get it's tempting to think of a technological fix (even one as risky as an Earth-shattering nuclear explosion), but we have to question ourselves more.
A 30yr break on an exponential process with dangerous tipping points seems like an awesome deal
Of course it doesn't work as the only fix, and there is the danger that it could be used as an excuse to slow down necessary changes. But the situation we currently find ourselves in is one that moves in the right direction (per-capita CO2 emissions peaked in the late 80s in the EU-27 and the 00s in the US, and many lower-emission solutions now have better economics than their established counterparts) but inertia an an ill-timed increase in the standard of living of China and India mean we are not moving nearly fast enough. More time is one of the most valuable things we can get in this situation
