ask why most plants evolved to be happiest at 4000-5000 ppm CO2.....after the ice melted at the start of the current interglacial period (which is about to end), CO2 was only about 240 ppm. At 160 ppm, all plant life dies. The planet was only 80 ppm away from a major extinction event......even at 400 ppm, plants are CO2 starved..... Satellite data shows the deserts are shrinking and the world is greening as CO2 increases.....when we hit the nadar of the current cold period, expected to be at least as deep as the Maunder Minimum, there will be crop failures and world wide starvation. The real worry is the magnetic field is weakening and incoming cosmic radiation is at all time measured highs and continues to climb. Cosmic radiation causes nucleation of water vapour, increasing cloud cover and albedo. This will be additive to the cooling that accompanies the grand solar minimum.
