You're not God.
From this morning's Wall Street Journal, "Concerned Scientists Reply on Global Warming":
"Trenberth et al. tell us that the managements of major national academies of science have said that 'the science is clear, the world is heating up and humans are primarily responsible.' Apparently every generation of humanity needs to relearn that Mother Nature tells us what the science is, not authoritarian academy bureaucrats or computer models."
Today's class of climate scientists, in particular, need to relearn that lesson. In going up against Mother Nature, they have proven themselves to be totally outmatched.
Stick to the science, fellas. Leave the wild-ass guessing and prognosticating to the politicians and the oracles.
