Earlier quoted context omitted.
Please abstain from propagating the "both sides" nonsense. One can admit to degrees of model uncertainty without insinuating that climate change is a matter of opinion.
How can you even say that? Climate science has uncertainty. There are definitely still things being debated.
Would you be willing to play Russian Roulette with a revolver with four bullets in the chambers just because there's uncertainty about whether the gun would go off when you pulled the trigger? Yes, there's a chance that climate change is going to no big deal. The most likely future occurrence is that things go the way the sober scientists at the IPCC give in their median prediction - a disaster but an eminently manageable disaster. The bit threat is that uncertainty goes both ways and climate change could very well end up being much worse than our median estimates. That's what keeps me up at night instead of urging more efforts go towards mitigation.
