In the Arctic, nearby soot may be a larger forcing than CO2

From the AGU Weekly Highlights, something I’ve pointed out more than a few times. See this photo of a moulin in upper Greenland, where carbon soot has collected at the bottom: Image from National Geographic online slide show – Photo: James Balog – click for more The authors find that BC (black carbon) emitted within…

Wildfire aerosols not handled well in climate modeling

From Los Alamos National Laboratory: Wildfires may contribute more to global warming than previously predicted They suggest that fire emissions could contribute a lot more to the observed climate warming than current estimates show. Haze of smoke emanating from the 2011 Las Conchas, NM fire. Particle analysis shows “tar ball” effect is significant LOS ALAMOS,…

Something else to worry about…carbon in the water

From the Oh Noes department and the Max Planck Institute comes this headline sure to cause worry worts scurrying for carbon removing water filters: Massive amounts of charcoal enter the worlds’ oceans Wild fire residue is washed out of the soil and transported to the sea by rivers Wild fires turn millions of hectares of…

More on Black Carbon from Univ of Washington

International study: Where there’s smoke or smog, there’s climate change By Hannah Hickey In addition to causing smoggy skies and chronic coughs, soot – or black carbon – turns out to be the number two contributor to global warming. It’s second only to carbon dioxide, according to a four-year assessment by an international panel. The…

A bit of a bombshell from the AGU IGBR: Black carbon is a larger cause of climate change than previously assessed

From the International Geosphere-Biosphere Programme via Eurekalert, some of the heat gets taken off CO2 as the ‘big kahuna’ of forcings, now there is another major player, one that we can easily do something about. I’ve often speculated that black carbon is a major forcing for Arctic sea ice, due to examples like this one. …
