Extended Data Fig. 7: El Niño/La Niña episodes (ONI) and seasonal precipitation and temperature.
From: Increased Amazon carbon emissions mainly from decline in law enforcement
a, Warm (red) and cold (blue) periods based on a threshold of +/−0.5 °C for the Oceanic Niño Index (ONI) (three-month running mean of ERSST.v5 sea-surface temperature anomalies in the Niño 3.4 region (5° N–5° S, 120°–170° W)), based on 30-year base periods revised every 5 years (ref. 42). b, Seasonal monthly Amazon mean precipitation 2010–2018 (solid light blue line) and temperature (solid brown line). The grey bar is the standard deviation for the monthly means 2010–2018, the dashed line for precipitation and temperature 2019 and the dotted line for precipitation and temperature 2020.
