Chris Ladd: Why Conservatives are Cautious About Climate Change
By HHR | September 4th, 2011 | Category: Opinion/Reviews | No Comments »
Before going any further on the subject of climate change, let’s remind ourselves what science is. Science is a process we use to determine facts, not a method for establishing truth. Truth is a more complex matter. Science takes a question like, “what is the airspeed velocity of an unladen swallow?”, and finds an answer through observation and repeatable experiments. If there is any lesson we learned from the 20th Century, it’s that science is only helpful in defining reality, not determining our values.
While science is very good at answering a specific question like “how much fat is in this doughnut?” It has a harder time answering complex matrix questions likes, “What should I eat?” In science, the farther you get from any experimental capability, the farther you get from reliable results. It’s not terribly hard to build an experiment that will predict with confidence how much salt there will be in your next order of French fries. It is very difficult experimentally to establish which combination of foods over a lifetime is best for any particular person.
You can find a perfect example of what happens when science is divorced from experimentation by talking to a physicist. The field of particle physics outran its experimental capabilities a long time ago and the mysteries they are confronting, with only limited tools for proof, are making them sound slightly mad.
