    This paper says, don't do it.

    • 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.
