Never mind what the Earth has, or has not, been doing "naturally" for thousands of years. What is mankind going to do NOW about all that CO2 in the upper atmosphere turning the Earth into a humind hot house?
Excuses for our weather getting more and more dangerous for us to live in won't help stop it.
By the way, RV's require much less energy to live in than do multi-thousand square-foot houses ... no matter how thick the insulation might be in those houses sitting underneath their huge capacity solar clad roofs.
Probably we all should be planning on TeePees or RVs for our grandkids.
