Global warming predictions are overestimated,
suggests study on black carbon
By Krishna Ramanujan
A detailed analysis of black carbon–the residue of burned organic
matter–in computer climate models suggests that those models may
be overestimating global warming predictions.
A new Cornell study, published online in Nature Geosciences,
quantified the amount of black carbon in Australian soils and found
that there was far more than expected, said Johannes Lehmann, the
paper’s lead author and a Cornell professor of biogeochemistry. The
survey was the largest of black carbon ever published.
