Paper Abstract

Phytoplankton may exert a warming influence on the planet by decreasing surface albedo. Compared with the case of pure seawater, the globally and annually averaged outgoing radiative flux is decreased by a probable value of 0.25 Wm-2. This value corresponds to about 20 percent of the net radiative forcing by greenhouse gases and anthropogenic aerosols since pre-industrial times, including indirect effects. The relative importance of phytoplankton is greater on Regional and seasonal scales, with forcing values reaching -1.5 Wm-2 in coastal zones and high-latitude regions during summer. The effects of space- and time-varying phytoplankton on surface albedo should be taken into account explicitly in the numerical modeling of climate change.
