A new report shows that this recent warm spell is nothing abnormal or unprecedented—during the 1990s there was simply a return to conditions present during 1931-1960. The reason for the shift is warm ocean temperatures that are, in turn, driven by variation in warm ocean currents from the tropics.
The whole “affordable energy” idea is based on the myth that if we don’t include those external costs in the price — the pollution costs, the national security costs — they just go away. They don’t. Keeping prices artificially low just transfers those costs to someone else, (..) someone who has to go off to fight a war to keep the shipping routes open. (...) If there’s one thing we can’t afford, it’s “affordable energy.”
