In his latest appearance, Bill Nye had a cameo on John Oliver’s show, in which he lit a globe on fire and dropped a few F-bombs. (I guess that passes as comedy.) He also said that Earth’s temperature could rise by 4 to 8 degrees, presumably Fahrenheit, since Nye didn’t indicate which scale he was using. His projection is within the range predicted by the IPCC, so at least he got that right.
But is setting a globe on fire an appropriate analogy to get the message across? Earth’s temperature has gone up 1.4 degrees F since 1880. Undoubtedly, another 4 to 8 degrees is quite a lot in a short period of time. It doesn’t take a master prognosticator to conclude that might cause some problems. But Earth is not — nor will it ever be — a flaming ball of fire. Earth isn’t Venus.
Ultimately, it seems that Bill Nye just panders to whatever he thinks the audience wants to hear. He thought (incorrectly) that they wanted to hear why GMOs were bad, so he altered his message when he got pushback. He won’t get pushback for exaggerating climate change, so it’s likely he’ll keep this up for a while.
