The Increasing Water-Use Efficiencies of Temperate and Boreal Forests of the Northern Hemisphere Over the Past Two Decades: What's behind the good news?

Subject Index Summary
Clouds (Albedo): Understanding how the albedo (or solar reflectance) of earth's clouds responds to anthropogenic-induced perturbations of the atmosphere is of paramount importance in determining the impact of the ongoing rise in the air's CO2 content on global climate, for both naturally-occurring and man-made aerosols have a strong influence on cloud albedo, with a global mean thermal forcing estimated to be of approximately the same magnitude as that of mankind's production of greenhouse gases, but of opposite sign. This summary, therefore, presents a brief review of a number of scientific papers that address this important subject.
