Sure, probably economics is the best explanation for this.

But I wouldn't ignore the sheer boredom of the thing: Al Gore was telling us his inconvenient truth's back in 2001. People can't stay freaked out about something for a quarter century.

It's hard to feel like I should make a sacrifice when decades go by with no real change to the cliamte.
