Blah-blah-blah, yappa-yappa-hey. “Lifestyle limitation.” Our lifestyle will be a hell of a lot more limited by coastal flooding, droughts, damage to crops, disease spread via insects, etc.
Where the US goes technologically, other countries tend to follow.
The “natural changes” argument is frankly rationalizing horseshit. If you want to drink that Kool-Aid, enjoy. Clean energy sources exist with current tech. Nuclear, solar, hydro, etc. No need to limit our lifestyle so much, other than maybe cutting back on air travel and insta-shipping. (Do we really need that iTrinket shipped from China overnight?) This assumes that hydrogen-powered aircraft can’t be made to work.
