I think our definition of "sacrifice" is different. I'm referring to a systemic drag on the standard of living going forward, due to reduced energy availability. Abundant, cheap energy is crucial for the best outcome going forward. I concur that international scale geoengineering will be required if the worse of the current estimates for CO2 induced warming are correct. So, we had best proactively prepare for that, just in case. As to current sea level rise and other climate change related effects, it's actually currently impossible to definitively separate the human signal from natural variability. We'll know more over time, of course. It'll be interesting to see if the upcoming Grand Solar Minimum will do anything to lower global temperatures on decadal timescales.
