HEY, WAIT, I THOUGHT THE SCIENCE WAS “SETTLED:” Could we be wrong about global warming? “Could the best climate models — the ones used to predict global warming — all be wrong? Maybe so, says a new study published online today in the journal Nature Geoscience. The report found that only about half of the warming that occurred during a natural climate change 55 million years ago can be explained by excess carbon dioxide in the atmosphere. What caused the remainder of the warming is a mystery.” Look, we should be switching to non-carbon power sources — like nice, clean nuclear power plants, or orbital solar — regardless. But this ought to deflate a few arrogance-bubbles. Though it probably won’t.
