What are El Niño and La Niña?  

El Niño, the warm phase of the El Niño Southern Oscillation (ENSO) started in July-August 2023 and developed rapidly as a strong event during the second part of 2023. El Niño is disrupting weather patterns, causing dry conditions in some parts of the world and excessive rainfall in others.  

Millions of people currently suffer from the impacts of droughts, heatwaves, and floods induced by El Niño and exacerbated by the climate crisis. The impacts of El Niño on food security, health and livelihoods are likely to last until at least the second half of 2024.  

La Niña corresponds to the cooling phase of ENSO, causing weather disruptions almost in reverse as those of El Niño. Cool, warm and neutral phases of ENSO alternate in cycles of five to seven years.  

How is the climate crisis impacting humanitarian action?   

Climate-related disasters are rising sharply as global temperatures keep rising. Extreme weather events such as droughts, floods, wildfires and heatwaves increased by 2.5 times in the current decade compared to the 1980s.  

The climate crisis acts a threat multiplier, exacerbating humanitarian needs, amplifying situations of conflict, causing mass displacement, intensifying food insecurity and pre-existing vulnerabilities and gender inequalities. 

As a result, humanitarian needs are quickly outpacing available response capacity. The number of people requiring humanitarian assistance due to climate-related disasters is projected to double to 200 million by 2050.
