You assume that human beings would be consistent ... if people are really worried about global warming they would modify their lifestyles in a manner that reflected this concern.

Much the way that all diabetics immediately modify their diet, once diagnosed, and stop using sugar. And all Catholic priests take a vow of chastity, embrace the gift of celibacy, and happily overcome their carnal urges. Or the way that the Republicans and their donors honored their decades-long commitment to reducing the national debt by vigorously opposing the Trump tax cut in late 2017 ... they did do that, didn't they?

It can be argued that our species possesses many virtues--but it could never be seriously argued that consistency is among them!
