Or something. Because from the CO2Science archive in 2006 there were two experiments on Citrus reticulata Blanco (Mandarin Orange Tree) showing that an extra 300 ppm CO2 in the air boosted plant growth on average by 24% when exposed to additional salt stress and by 35% when not exposed to salt stress. So if Donald Trump follows through on his pledges to expand American gas, oil and beautiful clean coal production and CO2 levels rise as a result, the Christmastime crop of Mandarin Oranges may be yuge this year.
