:... climate change facts ....” Facts? According to whom?
I want to know who measured the CO2 content of the atmosphere 650,000 years ago. For that matter, who measured it 650 years ago?
Absolute nonsense.
No one, of course. But the beauty of science is that we can, today, look back into the past, by a multitude of methods (ice cores etc.). The future, not at all, by the very definition of the scientific method. Don't blame science, blame rogue "scientists".
I think they get the data from ice core samples that haven’t been disturbed for 1000’s of years. That said, I’m not sure the assertion is true. It’s my understanding that there’s been (relatively recent) periods where the earth has had higher CO2 and temperature levels but this was before the industrial revolution. This attitude that higher CO2 levels CAN ONLY BE a bad thing can only be political, it’s not supported by science.
