Cochrane also suggests that there is no scientifically validated possibility that extreme climate events will cause systemic financial crises over the next decade, and that regulators are therefore stymied from assessing the risks on financial institutions’ balance sheets over a five- or ten-year horizon. But the sheer scale of the challenge should make us reconsider the temporal dimensions of regulation.
If temperature increases are to be kept within 2° Celsius of pre-industrial levels this century, about 80% of all coal, one-third of all oil, and half of all gas reserves must be left unburned. All of the Arctic’s oil and the remainder of Canada’s oil sands – the world’s largest deposit of crude oil – must be left in the ground, starting almost immediately.
Finally, it is said that the technocratic regulation of climate investments cannot protect us against un-modeled tipping points.
But this view simply ignores the extensive literature in climate economics. In this field, the work of Nobel laureate economist William Nordhaus is widely referenced. His Dynamic Integrated Climate-Economy (DICE) model has influenced many scientists’ and economists’ own modeling of tipping points, and the US government already relies on these “integrated assessment models” to formulate policy and calculate the “social cost of carbon.”
This interdependency between economics, policy, politics, public opinion, and regulation should be familiar from the crash of 2008. The dangerous over-leveraging that generated that crisis was an open secret; but those in a position, politically and culturally, to do something about it were willing to deny the systemic risk it posed. One can find the same denialism in the climate debate. According to the Center for American Progress, 139 members of the current US Congress (109 representatives and 30 senators; a majority of the Republican caucus) “have made recent statements casting doubt on the clear, established scientific consensus that the world is warming – and that human activity is to blame.”
