Tropical savanna fires are the dominant source of carbon from fire emissions and provide more than sixty percent of the global total1. The Kilimanjaro ice fields (3°04.6’S; 37°21.2’E, 5893 meters above sea level) are located near the largest savanna system in the world, and ice cores from the summit provide a Holocene history of East African climate2 from a data-sparse region of the world. This research uses the Northern Ice Field 2 (NIF2) core as it is one of the longest, coldest (borehole temperatures between -1.2°C to -0.4°C), oldest and best preserved Kilimanjaro ice cores2.
