Limiting Black Soot and Ozone – Buying Time against Climate Change
According to the journal Nature Geosciences, “increasing concentrations of black carbon have substantially contributed to rapid Arctic warming during the past three decades.”
A paper from that journal, “Climate response to regional radiative forcing during the twentieth century,” was authored by climate researchers Drew Shindell, at the NASA Goddard Institute for Space Studies, and Greg Faluvegi of Columbia University. Shindell, Faluvegi, and many other climate scientists believe that limiting black carbon sources may “buy the world some time” in the race to control climate change as richer nations develop their climate change policies and begin taking the slow steps towards overhauling their carbon heavy energy sources.
The researchers assert that aerosols are responsible for “half or more” of Arctic warming. Unexpectedly, their paper’s claims and recommendations sparked a flurry of critical emails, perhaps due to confusion over the atmospheric roles of different aerosols.
