Arrhenius said raising the world temperature was a good thing because he feared a new ice age. He said burning coal would save us. Back around 1900, when CO2 levels were about 300 ppm, he said reducing CO2 by half (to 150) would lower world temperature by 4 degrees. (BTW at 150 ppm, most plants will stop growing.) Doubling it (to 600) would raise world temps by 4 degrees, he said. Quadrupling it (to 1200) would raise world temps by 8 degrees. He knew nothing about feedback effects or solar or other climate effects.
