"Climate change" means pseudoscientific gibberish.
Real science makes testable predictions, that are backed by observed facts.
"Climate change" means "I know anthropogenic global warming is bullshit, but I want all the things we said you really really had to do because of it, so I simply going to move the goalposts and make the same demands over again."
Ever notice how the "climate change" crowd hates nuclear power? The one practical thing that could allows us to maintain our standard of living and avoid totalitarian 1 world government while avoiding the problem they claim to care about just seems to always be excluded from consideration.
Next time you corner a climate change believer ask them under what possible set of testable conditions they would actually consider their theory disproven.
