Carbon removal reduces natural feedback emissions – Hansen 2017

Hansen 2017… shows that reducing atmospheric burden, has a feedback effect where natural systems feedback emissions are also reduced by up to several hundred Gt C. Selected quote, "Studies suggesting multi-meter sea level rise in a century assume continued high fossil fuel emissions this century (Hansen et al.,…
