Wetlands — including mangroves, marshes and peatlands — also provide a multitude of high-value ecosystem services, including filtering water and buffering storm surges.

Many of the 20 pathways have similar ecosystem service benefits.

Another standout is avoided destruction of wetlands.

“They aren’t as extensive as forests or agricultural lands, but they’re the most carbon-dense systems on earth,” says Griscom.

Griscom says that this figure is more than 30 percent higher than previous estimates, both constrained and unconstrained, because this research filled gaps and included more natural pathways than prior syntheses.Carbon-14 has a half-life of 5,730 ± 40 years—, half the amount of the radioisotope present at any given time will undergo spontaneous disintegration during the succeeding 5,730 years.Because carbon-14 decays at this constant rate, an estimate of the date at which an organism died can be made by measuring the amount of its residual radiocarbon.The vast majority of the global carbon cycle is driven by nature.A tree falls, and as it decays some of its carbon atoms dissolve into the atmosphere.
