I wouldn't say the RWP, MWP or LIA overrode Milankovitch Cycles but were the noise of natural variability on top of them. It's unlikely that the RWP or MWP were warmer than it is now and the increase in temperature leading into them was much slower than the current warming rate.
No one (with any sense) is talking about de-industrializing the West. Instead of spending money on building new fossil fuel power plants we spend it on renewable energy. They may cost a little more to build but they don't have ongoing fuel costs like FF energy. Solar PV is already inexpensive enough and continuing to get cheaper that at least one coal plant has been cancelled because they didn't think they could compete with PV once it was completed. I get called an alarmist but people saying responding to anthropogenic global warming will destroy economies and plunge millions into poverty are also alarmists.
The supposed pause in warming in undetectable when you rigorously analyze it statistically as Grant Foster, a professional statistician, did here. The warming has continued pretty much as expected and temperatures are still within the uncertainty range of IPCC projections.
I think there is plenty of existing evidence to take action right now. If we wait until it's slap you in the face obvious the damages will cost us a lot more than doing something about it.
