Climate change does threaten the very basis of life on this planet, but a dramatically degraded environment here will still be much, much closer to livability than anything we might be able to hack out of the dry red soil of Mars. Even in summer, at the equator of that planet, nighttime temperatures are a hundred degrees Fahrenheit below zero; there is no water on its surface, and no plant life. Conceivably, given sufficient funding, a small enclosed colony could be built there, or on another planet; but the costs would be so much higher than for an equivalent artificial ecosystem on Earth, and therefore the scale so much more limited, that anyone proposing space travel as a solution to global warming must be suffering from their own climate delusion. To imagine such a colony could offer material prosperity as abundant as tech plutocrats enjoy in Atherton is to live even more deeply in the narcissism of that delusion—as though it were only as difficult to smuggle luxury to Mars as to Burning Man.
The faith takes a different form among the laity, unable to afford that ticket into space. But articles of faith are offered, considerately, at different price points: smartphones, streaming services, rideshares, and the internet itself, more or less free. And each glimmers with some promise of escape from the struggles and strife of a degraded world.
