Global Warming...Fact or Fiction?

I went back and checked at 6000 ppm there are some minor health effects but its ready breathable. Physical exertion would be very difficult but over time a young healthy person could probably adapt.

This paper says, don't do it.

The highest estimates I've seen referred to in literature for the Jurassic was 5000 ppm BTW.

the article completely ignores that oxygen level was higher than today during dinosaurs times, you can not look at co2 level alone.

The dinosaurs apparently breathed air that was much richer in oxygen than our air and lived in forests and grasslands that were far more combustible than ours. The metabolisms evolved to live is such an atmosphere might be radically different from ours.

Goes to the point that the earth will adapt whether we humans like it or not.
