When calculating the future impacts of government action, the federal government has very specific rules about how the calculation should be done. The Office of Management and Budget (OMB) clearly states that when calculating the cost of future impacts a standard “discount rate” of 7% should be used (a discount rate is used to take account of the fact that $10 today is worth more than $20 10 years from now). But when it comes to global warming regulation, that 7% rate is a problem for bureaucrats. With a 7% discount rate, the present cost of future global warming is virtually zero, even using the federal government’s excessively alarmist models. What’s a radical federal bureaucrat to do when math says that global warming will have virtually no negative economic effect? Well, they take a page from Common Core and change how they do the math.
