ESD Ideas: A Weak Positive Feedback Between Sea Level and the Planetary Albedo

Abstract. Since the planetary albedo of Earth above ocean is typically lower than above land surface, increasing sea-level reduces the planetary albedo. This causes a feedback that is very weak on the global scale, but significantly positive. Its amplitude can be assumed to be higher locally and to grow with the considered time scale.

Short summary
The oceans are typically darker than land surfaces. Expanding oceans through sea-level rise may thus lead to a darker planet Earth, reflecting less sun light. The additionally absorbed sun light may heat planet Earth, leading to further sea-level rise. Here, we provide a rough estimate of the strength of this feedback: it turns out to be very weak, but clearly positive, i.e., destabilizing the Earth system.
