Tropical rainforest response to marine sky brightening climate engineering† Helene Muri, Ulrike Niemeier andJón Egill Kristjánsson DOI: 10.1002/2015GL063363 Vol. 42 Issue 4 Geophysical Research Letters doi: 10.1002/2015GL063363 Keywords: Tropical forest;geoengineering;carbon cycle;climate;clouds Abstract Tropical forests represent a major atmospheric carbon dioxide sink. Here, the gross primary productivity (GPP) response of tropical rainforests to climate engineering via marine sky brightening under a future scenario is investigated in three Earth system models. The model response is diverse, and in two of the three models, the tropical GPP shows a decrease from the marine sky brightening climate engineering. Partial correlation analysis indicates precipitation to be important in one of those models, whilst precipitation and temperature are limiting factors in the other. One model experiences a reversal of its Amazon dieback under marine sky brightening. There, the strongest partial correlation of GPP is to temperature and incoming solar radiation at the surface. Carbon fertilization provides a higher future tropical rainforest GPP overall, both with and without climate engineering. Salt damage to plants and soils could be an important aspect of marine sky brightening. -- You received this message because you are subscribed to the Google Groups "geoengineering" group.
