Do You Believe In Global Warming

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:

  1. gamma rays reaching the earth’s surface
  2. the solar winds and other variations in the sun
  3. the relative location of the continents
  4. variation in the earth’s orbit
  5. natural and man-made air pollution including volcanic eruptions
  6. comet and asteroid collisions
  7. 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.
