Suppose that a senator asks an economist to make all calculations using a very low discount rate. What does this mean about decisions on climate change? Group of answer choices With a low discount rate, the damages that CO2 causes to future generations have almost no cost or value today, so it is economically optimal to take only a few tiny actions now to reduce CO2 emissions With a low discount rate, the damages that CO2 causes to future generations make people a little better off today, so it is economically optimal to take small actions to increase CO2 emissions now With a low discount rate, the damages that CO2 causes to future generations have absolutely zero cost or value today, so it is economically optimal to ignore CO2 emissions in decision-making With a low discount rate, the damages that CO2 causes to future generations make people a lot better off today, so it is economically optimal to take large, expensive actions to increase CO2 emissions now With a low discount rate, the damages that CO2 causes to future generations will be quite costly or valuable today, so it is economically optimal to take many actions now to reduce CO2
