Well Jeeze, I guess we’ll have to grow some more plants.

So this means that the CO2 has been this high before?

No, it just proves that whoever did this study was high.

Oh no... They are all full of crap... :)

The Euroweenies sourced it from PDF below... But NOAA turned it into a PDF so that the graph could no longer be hotlinked. So the Euroweenies are the only source that can still be hot linked for that same graph. NOAA doesn’t like us using that graph to prove their BS wrong. :)

Oh dear! That obligates me to use it often.

It got down to 190 ppm during last Ice Age, uncomfortably close to the 150 point where plant life dies.

The globally warm late dinosaur period CO₂ excess was solved very quickly, so they say.
