Sure does, that's why "climate change" is so prolific among a certain subculture.
Yup.
The paranoid dooms day global warming preppers have entire forums where the fantasize with each other about how many carbon credits they have hoarded in the basement, and how they will shoot anyone who comes and forces them to use an internal combustion engine. Tactical hyper-mileage during the post enviro-apocalypse is also hot stuff. Paying 3 - 5 times retail for a used Prius and solar panels was not uncommon not even a year ago.
Those SHTF people are pretty nuts - paranoia, fear, groupthink, and self reinforcement are powerful drivers for self delusion.
