So what? People do bad science, bad business, bad education <i>all the time</i>, because of unconscious biases, because of pressures to 'succeed', publish, etc. How many people are 'playing the game' in this old world?<p>Not to excuse exaggerations: but just because some people get overzealous, that <i>doesn't</i> change the facts ... e.g. that glaciers worldwide are shrinking, the oceans are becoming more acidic.<p>Many GW deniers are also guilty of being blind in one eye.
