I actually work on reducing emissions tangentially and am absolutely not a "denier", but I have not seen any evidence that our models are so accurate that we can predict the tipping point from halting increases to decreases within 1%.

Just took a number which carbon is removed from air-sea-plants natural circulation. The increase in CO2 stops when emissions match the removal of CO2 from circulation as permanent basis. And that figure seems to be about 1% of our emissions. But the key issue is that those two numbers need to match in order to actually stop the climate change permanently which is so far away from every politicians discussion points. All the renewables and storage technologies fail when we start to calculate amount of material required to build them and mining of those resources. Only energy technology so far that could actually do it is nuclear. As for uranium limited reserves they are calculated about 0.1 cent per kwh price limit. It is one of those situations where emotions points towards renewables while numbers are clearly for the nuclear if people could accept tiny risk of having two bananas worth of radiation or even the extreme case of getting so high radiation dose that it would give as high cancer risk as the average alcohol consumption.
You're probably right, but that's really nothing good. Our models are poor and despite not knowing where irrecoverable tipping points lie exactly, we blast full steam ahead with our emissions.
