I don't want this to sound political, but what's the point in reducing GHG emissions?
Given that it takes essentially forever on human-relevant timescales for natural sinks to draw down CO2 and that +4C of warming is pretty much baked in (consequences aside) by the end of the century given current concentrations and feedback loops, isn't it pointless to do so?
I'm all for protecting the natural environment, but I doubt it'll change anything in the near term.
