There's a pervasive solution bias in thinking about climate change and this is an example of it. If reducing emissions won't work and we have to find a solution, then surely negative emissions is the answer? The problem with that is that the fact that we need a solution does not mean that a solution exists and that eliminating solutions that definitely won't work doesn't mean that the remaining ones have to work.
