Not OP, but it’s disingenuous to keep up making tipping points and giving estimates for them given the error bars are bigger than the deltas involved.

Some people will argue that this rethoric is necessary to keep the attention of the public, but I fear that this will create more harm than good. We have already seen this, the climate change denier platform has been getting a good run out of showing the failed exaggerations of the 80s.
