SYNCOOL constitutes an acronym for "photosynthetic cooling". Photosynthetic cooling constitutes a major global equilibrium force via the conversion of solar radiation into biomass. Atmospheric carbon/CO2 is an essential element in the conversion of solar radiation into biomass. Because water is a necessary element in biomass conversion, rainforests constitute an optimal biomass conversion engine. Rainforests are conversely driven by the chilling and subsequent condensation of atmospheric vapor within the rainforest canopy. Rainforests consequently functions in synergy with photosynthesis as an salient augmentation/multiplication factor. Because of the highly excited state of activation via abundance of water, intense sunlight and an extensive/dense foliage canopy, an increase in the carbon/CO2 content of the atmospheric air with invariably accelerate the rate of biomass conversion in a rainforest.
