We're putting back in the atmosphere in less than a century fossil fuels that has been trapped in millions years timeThe Earth itself, emits CO2 from every volcano, spring and well. At least our fossil fuel CO2 came from the same atmosphere we're refilling. Burning fossil fuel emits CO2, so does fermenting alcohol, cheese, and raising bread. The carbon was in the air before; we're putting it back where it belongs.
You have been unable to describe how you would experiment on climate, therefore the hoax is your fantasmatic ask for experiment testing climate change mitigation.The climate warms or cools or doesn't change measurably; it can't be changed in any manageable way. There's never been an experimental test of man made greenhouse gas on climate temperature.Experiments don't just mean testing to destruction; they start with the smallest input required to create the smallest measurable change. With billions spent annually, to measure climate change; not one peer reviewed journal published an experiment testing climate change mitigation. That's how you can tell its a hoax.
