We can start to arrest climate change today. In fact we are arresting it at the same time that we continue to change the climate. Significant objections are raised by vested interests regarding the cost of change. But the cost is much less than the cost of doing nothing. And the cost is not that great. Nordhaus and Stern disagree on how to calculate it, using net present value or rolling future value, but the costs are able to be calculated and compared to the cost of doing nothing. Right now the cost of acting is significantly less than the cost of doing nothing if we look out 20, 50, 100 years. Therefore we should begin to act. You can begin to act. How should you act? That depends on who you are. Interestingly you don’t have to change who you are but how you think about yourself.
