abstract = "The outstanding tropical land climate characteristic over the past
decades is rapid warming, with no significant large-scale
precipitation trends. This warming is expected to continue but the
effects on tropical vegetation are unknown. El Nino-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
Nino heat and drought anomalies using an atmospheric transport
inversion. Based on the global atmospheric CO2 and fossil fuel
emission records, we find no obvious signs of anomalously large
carbon release compared with earlier El Nino 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.",
