We Need to Plant Many New Amazon Equivalents, Not Destroy Our Existing One

If the entire Amazon burned down, a release of 90 Pg of carbon to the atmosphere, equivalent to a 40 ppm rise in atmospheric CO2, was mentioned in the previous video description based on Yadvinder Malhi blog. By the same token, if people on Earth got their act together and planted a new Amazon (about 390 billion trees, estimated from Amazon Wikipedia) this would drawdown about 40 ppm (90 Pg) or 10% of atmospheric concentration. At present, atmospheric CO2 rises 2-3 ppm/year, so 40 ppm is only between13-20 years worth of global emissions.

Vital Significance of Amazon Rainforest as Carbon Sink

How significant, on a global scale, is the Amazon Rainforest? Best I can tell, correct annual numbers are: Tropical rainforests account for 34% of land-based global photosynthesis; Amazon Rainforest is almost half that, namely 16%.

Total oxygen produced by land-based photosynthesis is 330 Pg, thus Amazon is 54 Pg. Ocean phytoplankton oxygen production is 240 Pg. Total global photosynthesis is 330 + 240 = 570 Pg of oxygen (58% land, 42% ocean).

Amazon produces 54/570=9.5% of total global oxygen; with carbon sink being 9.5% of global plant total sink.
