- According to WMO, El-Nino fuels growth in CO2 concentration in environment for ex. growth spurt in CO2 in 2016 was fuelled by the El Niño event, which started in 2015 and had a strong impact well into 2016.
- The El Niño event had triggered droughts in tropical regions and reduced the capacity of “sinks” like forests, vegetation and the oceans to absorb CO2.
- These sinks currently absorb about half of CO2 emissions but now there is a risk that they may become saturated. Once these sinks become saturated it will increase the fraction of emitted CO2 which stays in the atmosphere.
