OK. here are some facts.
Carbon Dioxide is an essential gas in the makeup of the atmosphere. Without it all life on Earth would die. It’s no more a “pollutant” than is Oxygen.
Another fact: 500 million years ago CO2 levels were likely 10 times higher than now. There were no SUVs 500 million years ago.
And as I said, carbon is natural and without it, all life on earth would die.
But it's not logical to go from that to, "Therefore, carbon can't be a pollutant."
Similarly, you can't take carbon dioxide off the hook just because it's an essential gas in the atmosphere.
Another fact: 500 million years ago CO2 levels were likely 10 times higher than now.
Actually, probably more like 20 times what they were now. And it was lots hotter.
Then, at the SPICE, the CO2 levels and temperature plummeted. So how does this information support the argument that CO2 and temperature are not linked?
The Global Warmers' point is that we're forcing the climate system with CO2, regardless of natural fluctuations.
There were no SUVs 500 million years ago.
Actually, there were...Simple Underwater Vertebrates were just beginning to appear. ;-)
