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

Posted on March 7, 2013 by

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 it tends to melt faster than white snow under sunlight … Continue reading →

More on Black Carbon from Univ of Washington

Posted on January 16, 2013 by

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 … Continue reading →

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

Posted on January 15, 2013 by

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 … Continue reading →

Another hole in the climate models – no lamp black forcing

Posted on November 29, 2012 by

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 be replaced, study says By Sarah Yang, Media Relations BERKELEY … Continue reading →

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

Posted on September 3, 2012 by

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 now that absorption has been demonstrated to be far less. … Continue reading →

Natural Variability in the Widths of the Tropics

Posted on May 25, 2012 by

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 carbon and tropospheric ozone”, by Robert Allen et al, hereinafter … Continue reading →

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

Posted on May 24, 2012 by

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 a gas. Here’s the release: On Thursday, May 24, at … Continue reading →

Does This Analysis Make My Tropics Look Big?

Posted on May 22, 2012 by

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 zones further north and south, moving the Saharan aridity into … Continue reading →

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

Posted on May 16, 2012 by

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 the strength of 400,000 Hiroshima bombs each day that animals … Continue reading →

Too many cooks spoil the carbon footprint

Posted on April 9, 2012 by

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, but in the zealous rush for solutions, sometimes too many … Continue reading →

Extremely Black Carbon

Posted on February 7, 2012 by

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, on the climate. Me, I think it’s worthwhile controlling black … Continue reading →
