Until humans can find a way to geoengineer ourselves out of the climate disaster we've created, we must rely on natural carbon sinks, such as oceans and forests, to suck carbon dioxide out of the atmosphere. These ecosystems are deteriorating at the hand of climate change, and once destroyed they may not only stop absorbing carbon from the atmosphere, but start emitting it.... PHYS.ORG · 3 months
