“Climate deal: the pistol has fired, so why aren’t we running?”
What it requires is devoting yourself single-mindedly to the task. You don’t get to drink beer with dinner and run a three-hour marathon. You don’t get to skip training days. You go to bed early every night, because you’re bone-tired. You have to run even when it hurts. Especially when it hurts.
Translated into carbon terms: you don’t get to go drilling or mining in new areas, even if you think it might make you lots of money. The Arctic will have to be completely off limits, as will the Powder River Basin of Montana and Wyoming. The pre-salt formations off Brazil, and the oil off the coasts of north America too.
