NASA study eyes soot’s role in 1800s glacier retreat

A NASA-led team of scientists has uncovered strong evidence that soot from a rapidly industrializing Europe caused the abrupt retreat of mountain glaciers in the European Alps that began in the 1860s, a period often thought of as the end of the Little Ice Age. The research, published Sept. 3 in the Proceedings of the National Academy of Sciences, may help resolve a longstanding scientific debate.

Black carbon worse for climate than thought

Black carbon - soot to you and me - turns out to be causing twice as much global warming as previously thought.

Cutting soot emissions could be climate quick fix

Reducing soot emissions from diesel engines and other sources could be the fastest, most economical way to slow the melting of Arctic sea ice, researchers say.
