Those dirty trees: why hasn't the EPA called for trees to be regulated?
From the University of North Carolina at Chapel Hill one wonders why they have not thrown the PM10 hammer (or ax) at trees to save humans from their terrible effects…
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…
Aerosols from Moderate Volcanos Now Blamed for Global Warming Hiatus
While looking for quotes on an upcoming post about Ocean Heat Content, I ran across the press release for a new paper (in press) by Neely et al, which blames…
Dust's excellent global adventure ends in California's Sierra Nevada
From the Scripps Institute: Saharan and Asian Dust, Biological Particles End Global Journey in California UCSD, NOAA study is the first to show that dust and other aerosols from one…
Harvesting Fog: The No-Regrets Option
Guest Post by Willis Eschenbach I’ve written before about the “no-regrets” option when one is faced with uncertainty. It relates to one of my favorite rules of thumb. I often…
PODEX Experiment to reshape future of Atmospheric Science by getting a handle on aerosols and clouds
Polarimeter Definition Experiment (PODEX) in Southern California. The brightness, or “intensity,” and polarization of reflected light provide different information about the elements that make up a scene, apparent in this…
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…
Law of unintended consequences – fuel tax designed to lower air pollution actually creates more air pollution
Another application of the Grecian government formula blows up in their faces. From EuroNews: Smog hits Athens as cash-strapped residents choose fire over fuel Bad news for austerity-stricken Greeks is…
Why doesn't the AR5 SOD's climate sensitivity range reflect its new aerosol estimates?
This article is a detailed complement to Matt Ridley’s Op-Ed today in the Wall Street Journal: Cooling Down the Fears of Climate Change Evidence points to a further rise of…
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…
Some new climate surprises blow in with the dust
From NASA: Dust’s Warming Counters Half of its Cooling Effect Dust that routinely rises above the world’s deserts causes a more significant localized warming effect than previously thought, a new…
Sunshade geoengineering people apparently have been in the midday sun too long
From the Carnegie Institution , not just aerosol injections, but effective aersol injections. Law of unintended consequences be damned. Improving effectiveness of solar geoengineering Washington, D.C.— Solar radiation management is…
New paper cuts recent anthropogenic warming trend in half
Tamino (aka Grant Foster) will have his knickers in a twist over this one. Guest post by Marcel Crok (from his blog De staat van het klimaat) An interesting new paper…
Yet another fix needed for climate models – this time due to aerosols
There are so many updates and fixes needed to the climate models these days its almost like watching a car undergoing a perpetual repair process. When does the time come…
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…
SLACing the soot
From the DOE/SLAC National Accelerator Laboratory X-ray vision exposes aerosol structures Laser probes microscopic components of air pollution Menlo Park, Calif. — Researchers at the U.S. Department of Energy’s (DOE)…
The EPA's Unethical PM2.5 Air Pollution Experiments
By John Dale Dunn MD JD (via email) United States Environmental Protection Agency (EPA) Administrator Lisa Jackson testified before Congress in September of 2011 that small-particle (2.5 microns or less)…
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…
Pollution enhanced thunderstorms warm the planet?
From the DOE/Pacific Northwest National Laboratory, a new paper in GRL saying something that doesn’t make much sense to me. As shown in the diagram above, thunderstorms transport heat from…
