Modern C4 photosynthesis plants (grasses) evolved during the miocene when CO2 levels dropped down to below 200ppm. They evolved to tolerate those low levels most of our food chain is grasses...corn,wheat,rice,sorghum,barley,rye all are C4 grasses and all of them are less than 12 million years old having evolved during the glacial periods. C4 photosynthesis is viable down to 150ppm below that you get CO2 starvation. The earth is at 400+ ppm it would take hundreds if not a thousand years for the natural CO2 sinks of the oceans the number one sink via carbonate formation and two land based mafic rock weathering to pull CO2 down under 200 even if humans dimmed the sky and plants died off due to lack of solar input. The amount of carbon in the oceans is so vast that when not if the atmosphere concentration drops the bicarbonate balance between the air and water reverses and CO2 out gasses to bring back a new level of equilibrium that process would run for nearly a millennium keeping CO2 levels above 200
The same idiocy wanted to spray soot on the ice caps to stop global cooling.
Trust the science....
Bill Gates was into technology when technology was in it’s most critical stage of infancy ...
If Gates had been born five years earlier or 3 years later he would have been a quite ordinary Harvard dropout... making good money, but not being the multibillionaire he is today.
Grim and depressing.
they predict everything.
Yeah the report basically laid out the worst parts of that pesky last book. Months of darkness, freezing temps as far South as the tropics. 3 to 100 meters of ash across the whole North American continent. The planetary food web would collapse billions would starve or freeze to death. The report was quickly.pulled market secret and locked away. You really would not have to drill into Yellowstone lake just sinking a high enough yield device to the bottom would allow the fireball to vaporize enough of the overbearing rocks to pop the magma chamber the yield was not as large as one would think something the Russians or Chinese could put in a shipping container would do the trick.
Even more grim and depressing.
Would those particles happen to be +- about 150 grains?
