On the topic of atmospheric CO2 and the fact that it's concentration hasn't been as high in at least 800,000 years, one wonders what Smokey has been smoking.

...I’m not sure myself. But I am pretty sure that CO2 has been up to twenty times higher in the past. Selecting a time frame like ‘800,000 years’ reeks of cherry-picking....
Here's what's been happening with atmospheric CO2. Go towards the end of the video to see the levels over the last 800,000 years.
BTW - put your head in a vice before you read the article by Ronald D "it's insects" Voisin.
