It is never only about physics when we talk about impact of climate change. Even if you talk about catastrophic runaway warming, it is caused by ecosystem-level feedback loops.
The question raised is what are the possible net-good feedback loops? Will flora benefit from it widely and expand everywhere? Will that be a good thing?
To paraphrase:
This is where you are wrong. You may not understand it but the science is far from solid. It is not well known what happens when ecosystems react to too much greenhouse gases. "The physics is indisputable." is a hollow statement.
disclaimer: I am for active prevention of such things occurring, just for strategic reasons like "we don't have a clue what we're doing and we are apparently doing SOMETHING". But to claim it is obvious and "indisputable" sounds like dangerous propaganda to me.
- yequalsx 9y agoI was responding to this statement: "It is also absurd to be so certain about our potential impact on something as complex and chaotic as climate." It is possible to be certain about impacts on climate. Increase CO2 in the atmosphere by a factor of a trillion. There will be runaway warming in the immediate term. This is known and well understood. I'm not claiming we are near this point but the suggestion that we can't know some effects because climate is hard is absurd.
- _Tev 9y agoCertain aspects can be certain, sure, but overall effects are beyond our understanding. We just have too small sample size ... But while we disagree on what we know you're right that it's not clear cut and one can argue we already know quite a bit - e.g. those immediate effects is something I can imagine we have good grasp on, I've not studied that in depth as most debates are about ultimate consequences.
