Have you also asked an AI chatbot about climate and found the answer to be quite good? Maybe that is because it was you who asked.
Some AI (e.g. Grok) tailors their response to suit your beliefs. It’s called ‘AI sycophancy’ (a new word I just learned.)

For me the answer is neither. Let's get out of fossil fuels fast enough to minimise both of these very real risks.

NCAR is quite literally our global mothership.
Everyone who works in climate and weather has passed through its doors and benefited from its incredible resources.
Dismantling NCAR is like taking a sledgehammer to the keystone holding up our scientific understanding of the planet.
