Is this some kind of a joke? Global warming, full stop. Plants are not starved, they were ubiquitous until we chopped “most” of them down.

  It's science. Land-based plants evolved when CO2 levels were much higher than today. [1] In fact levels have been steadily declining from 3000 ppm 150 million years ago; the current, holocene rise is a relatively minor bump.

    And by the way global temperature 150 million years ago was the same as today, +/- 2deg C.

      Could be. But the bio-make up of the planet was different then, yes?
