Last night I played Team Trivia at a local bar. We were asked the following
According to a Yale study, what percentage of the population believes in Global Warming.
The answer was 70%. Hmmm. I wonder how I would have responded to such a question? Yes, I believe scientists when they say the world warms and cools and that we are in a warming cycle that began about 250 years ago. I do think that climate changes with time and that man is probably responsible for some of that change. But do I believe in Global Warming?
I’m stumbling over the word believe. The word believe implies a religious experience. I don’t think I have a belief structure associated with the notion that world climate changes. I think the climate changes for a whole host of reasons including variation in all of the following:
- gamma rays reaching the earth’s surface
- the solar winds and other variations in the sun
- the relative location of the continents
- variation in the earth’s orbit
- natural and man-made air pollution including volcanic eruptions
- comet and asteroid collisions
- other things we haven’t figured out yet
I think item 7 puts me in the no camp when the word believe is used. I expect the answer to change as we learn more about the subject. Conventional wisdom in science changes all the time. I don’t know the answer, I’m sort of a climate change agnostic. I am very confident that Al Gore, the IPCC and James Hansen are wrong….but I might be wrong too.
Time will tell……lots of time. And lots more science too.
