age age-and-aging annual easily growth identified known trees tropical
Little was known about the age of tropical trees, because they do not have easily identified annual growth rings. No one had thought these tropical trees could be so old, or that they grow so slowly.
certainty changes co2 slowing
It's pretty much a certainty that big changes will happen, so we should be slowing down our CO2 emissions.
capacity carbon central current cycle earth flows found global growing half predicted rates remove roughly scientists understand
In the Central Amazon, where we found the slowest growing trees, the rates of carbon uptake are roughly half what is predicted by current global carbon cycle models. As a result, those modelsùwhich are used by scientists to understand how carbon flows through the Earth systemùmay be overestimating the forests' capacity to remove carbon dioxide from the atmosphere.
