Global Warming and the Stupid People

Ice core samples, ocean floor core samples, chemical analysis of the contents matched to the times of their origin, ie. the industrial revolution.  The current thawing of permafrost is now releasing more methane in the atmosphere and accelerating the process.  These are some of the things that constitute the clues of origin.  While the earth has indeed fluctuated climate many times, this time looks pretty interesting.  In the past, when climate patterns changed, there were quite a few less people and the borders were quite a bit less stiff.  To what extent should science be censored by politics?  If you take two sides of an issue, examine what each side has to gain if their perspective prevails, you at least have a sense of motivation for whomever is passing on their analysis.  Scientists gain grant money.  Industrialists protect some pretty big profits.  And "stupid" environmentalists?  Are they merely out to do battle against the capitalist economy, or do they have legitimate concerns for the well-being of humanity as a whole (and not just those who are profiting in the short term)?  Such a complicated topic, but most only know what someone else says about it, and what's said about global warning is about as politicized as it gets.  I tend to think about it the same way I think about painting my house:  if I stick my head in the sand when the paint is chipping, then the wood rots and the whole repair job has gotten that much more complicated and expensive.  But the ecosystem is not siding, and the complications potentially involve a fairly profound degree of suffering in other parts of the world.
