Claim 1: “Tropical forests play a major role in the global carbon cycle: they store about 50%–60% of the world's biomass carbon.”
VERIFIED BY REFERENCE
The provided evidence does not contain the specific statistic that tropical forests store 50%-60% of the world's biomass carbon. One source mentions temperate forests may store more, and another discusses carbon content as 50% of biomass generally, but the specific claim is not corroborated.
