Black Carbon Soot shrank the 19th century glaciers – but why isn’t it listed as a culprit today?

Watts Up With That?

From the University of Colorado at Boulder comes this press release and accompanying photo. The photo, showing hazy pollution laden air in the Bernese Alps, makes me wonder why they don’t attribute current glacier ice loss issues to soot. Asia in particular, is a leader in soot production, right next to those Himalayan glaciers that the IPCC erroneously told us would be gone by 2035.

Soot suspect in mid-1800s Alps glacier retreat

Scientists have uncovered strong evidence that soot, or black carbon, sent into the air by a rapidly industrializing Europe, likely caused the abrupt retreat of mountain glaciers in the European Alps.

The research, published Sept. 2 in the Proceedings of the National Academy of Sciences, may help resolve a longstanding scientific debate about why the Alps glaciers retreated beginning in the 1860s, decades before global temperatures started rising again.
