This warming is expected to continue but the effects on tropical vegetation are unknown. El Niￃﾱo-related heat peaks may provide a test bed for a future hotter world. Here we analyse tropical land carbon cycle responses to the 2015/16 El Niￃﾱo heat and drought anomalies using an atmospheric transport inversion. Based on the global atmospheric CO 2 and fossil fuel emission records, we find no obvious signs of anomalously large carbon release compared with earlier El Niￃﾱo events, suggesting resilience of tropical vegetation. We find roughly equal net carbon release anomalies from Amazonia and tropical Africa, approximately 0.5 PgC each, and smaller carbon release anomalies from tropical East Asia and southern Africa. Atmospheric CO anomalies reveal substantial fire carbon release from tropical East Asia peaking in October 2015 while fires contribute only a minor amount to the Amazonian carbon flux anomaly. Anomalously large Amazonian carbon flux release is consistent with downregulation of primary productivity during peak negative near-surface water anomaly (October 2015 to March 2016) as diagnosed by solar-induced fluorescence. Finally, we find an unexpected anomalous positive flux to the atmosphere from tropical Africa early in 2016, coincident with substantial CO release. </p> <p>This article is part of a discussion meeting issue ￢ﾀﾘThe impact of the 2015/2016 El Niￃﾱo on the terrestrial tropical carbon cycle: patterns, mechanisms and implications￢ﾀﾙ.</p> Life Sciences & Biomedicine - Other Topics FLUX 0301 basic medicine Hot Temperature 550 551 global warming 01 natural sciences Carbon Cycle Greenhouse Gases 03 medical and health sciences [SDU.STU.CL] Sciences of the Universe [physics]/Earth Sciences/Climatology CHEMICAL-TRANSPORT MODEL carbon cycle INVERSION Biology TEMPERATURE 11 Medical and Health Sciences 0105 earth and related environmental sciences tropical forests El Nino-Southern Oscillation Evolutionary Biology Tropical Climate Science & Technology Atmosphere PHOTOSYNTHESIS EQUATORIAL PACIFIC Articles 06 Biological Sciences 15.
