Crichton's point is it doesn't matter how many people *think* he's is wrong about climate change, it only takes one person to *prove* him wrong. Science isn't consensus, and nothing has been proven.
Yet when deciding what to do about potential problems, we have to take consensus into account....exactly for the reasons you state - that we can't know things with absolute certainty.
Now that the Republicans are out of the White House, expect the climate change crisis to conveniently fade away from the public consciousness.
US centric much? This is a global problem, discussed all over the world.
A HACK? Your opinion is wrong. Crichton was thought-provoking and insightful, and he was a gifted story-teller
No, the GP had it right. He was a hack, wrote thinly disguised straight-to-Hollywood scripts, and will soon be forgotten, your fanboy hissyfit nonwithstanding.
