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

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 set of images collected by the Airborne Multiangle SpectroPolarimetric Imager … 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 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
