In this case, who cares? Each of you own and operate a vehicle that dumps out a ***** to of CO2 every time you start it. If you care about the enviroment, sell your Jeep, buy a bicycle and eat tofu. Both sides of the argument is invalid, nobody really cares at all, stfu and move on. If the ice caps melt, BFD, move inland. If we have an other ice age, BFD, buy a jacket. Either way humans will adapt and overcome anything that happens.
