NCAR says targeting specific pollutants would slow SLR

From the  National Center for Atmospheric Research/University Corporation for Atmospheric Research I can see the EPA jumping all over this one. Black carbon is likely a contributor, as it changes the albedo of ice sheets and one that is much easier to manage. Problem is, the USA isn’t much of a black carbon emitter any…

NASA on the sun: ‘…tiny variations can have a significant effect on terrestrial climate.”

Researchers have considered the possibility that the sun plays a role in global warming. From NASA GSFC:  Solar Variability and Terrestrial Climate In the galactic scheme of things, the Sun is a remarkably constant star.  While some stars exhibit dramatic pulsations, wildly yo-yoing in size and brightness, and sometimes even exploding, the luminosity of our…
