Boss: I invited a climate scientist to explain the risk of climate change to our company. Man: Human activity is warming the earth and will lead to a global catastrophe. Dilbert: How do scientists know that? Man: It's easy. We start with the basic science of physics and chemistry. Then we measure changes in temperature and CO2 over time. We put that data into dozens of different climate models and ignore the ones that look wrong to us. Then we take that output and run it through long-term economic models of the sort that have never been right. Dilbert: What if I don't trust the economic models? Man: Who hired the science denier?
