The big problem is that due to feedback effects, there is no stopping at 1.5C unless we engage in highly risky mitigation techniques such as blocking sunlight with aerosols. Once permafrost begins to melt, fire season expands, and the planet's albedo shrinks, then warming begets more warming. We are already well along this path, and the feedback effects are now accelerating.

- edgefield 4y agoYes, magic is indeed the best solution.
- defrost 4y agoHardly magic, it's feasible albeit difficult engineering. For that matter large scale carbon sequestration that stores more carbon than it creates, blue hydrogen, etc may well be green wishful thinking.
