Clouds, radiative forcing, and climate models – still tweaking

As most readers know, clouds are still poorly understood and under-represented in climate models. This new research may help. From: DOE/Pacific Northwest National Laboratory Effect of cloud-scattered sunlight on earth’s energy balance depends on wavelength of light Accounting for wavelength effects will likely improve climate models RICHLAND, Wash. — Atmospheric scientists trying to pin down…
