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

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…

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…

Study: Black carbon aerosol forcing may be an important factor affecting the snow & ice cover in the Northern Hemisphere

We’ve had several essays here at WUWT  on the role of Black Carbon soot and its role in affecting surface albedo. Anyone who has ever witnessed “dirty snow” knows that…

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…

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…

Another hole in the climate models – no lamp black forcing

Interesting point, but I wonder how such a change would come about when people often can’t afford an alternative? Let there be clean light: Kerosene lamps spew black carbon, should…

Another failure of climate models – carbon soot warming actually far less than models predict

From Boston College another failure of climate models to capture reality has been exposed by field empiricism. The map below from NASA’s Earth Observatory will likely have to be revised…

Natural Variability in the Widths of the Tropics

Guest Post by Willis Eschenbach In my previous post, “Does This Analysis Make My Tropics Look Big?“I discussed a paper called “Recent Northern Hemisphere tropical expansion primarily driven by black…

California Air Resources Board to make webcast on 'black carbon and other “short-lived” greenhouse gases. '

Short notice – this is on NOW. Worth watching, even if only for how they justify saying ‘black carbon and other “short-lived” greenhouse gases.’. I didn’t know black carbon was…

Does This Analysis Make My Tropics Look Big?

Guest Post by Willis Eschenbach There is a new paper in Nature magazine that claims that the tropics are expanding. This would be worrisome because it could push the dry…

Carbon soot may be driving the expansion of the tropics – not CO2

From the University of California – Riverside it seems that black carbon soot is driving tropical expansion. How could this be? I thought CO2 was all powerful, so powerful with…

Too many cooks spoil the carbon footprint

From the American Chemical Society  it seems that newer is not always better. Even Yale environment360 bought into this idea. I should add that I’m all for reducing carbon soot,…

Ramanathan and Almost-Black Carbon

Guest Post by Willis Eschenbach My thanks to Nick Stokes and Joel Shore. In the comments to my post on the effects of atmospheric black carbon, Extremely Black Carbon, they…

Extremely Black Carbon

Guest Post by Willis Eschenbach Of late there has been a lot written about the effect of “black carbon”, a.k.a. “soot”, and also “brown carbon”, a.k.a. wood and dung smoke,…
