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 don’t attribute current glacier ice loss issues to soot. Asia … Continue reading

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: … Continue reading

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 … Continue reading

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 … Continue reading

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

Dust in the wind: Melt ponds in the Arctic hasten overall melting

I’ve often wondered if carbon soot plays a role in this. See our recent WUWT story about how black carbon’s role has been underestimated, and note that Arctic melting is listed as one of the effects. See also the tag … Continue reading

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 … Continue reading

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 … Continue reading

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 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

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

Greenland Ice Sheet albedo drops ‘off the bottom of the chart’ – but look closer as to why

Got this in the mail just as I posted my open thread announcemnt. I’m too busy this weekend to say much else except to post this tweet from Bill McKibben and some past blog excerpts and invite discussion. Bill McKibben … Continue reading

Shocker: The Hansen/GISS team paper that says: “we argue that rapid warming in recent decades has been driven mainly by non-CO2 greenhouse gases”

Note: This will be a top post for a day or two, new stories will appear below this one – please scroll down. ============================================================ No, this isn’t a joke, it isn’t a fake document, and it isn’t a misinterpretation. It … Continue reading

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

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

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

One side effect of a warmer Arctic, it will be cleaner due to black carbon scavenging

No polar bears and Arctic foxes  aren’t scavenging carbon, but more moisture during summer months will. Arctic air may become cleaner as temperatures rise The air in the Arctic is cleaner during summer than during winter. Previous studies have shown … Continue reading
