The WMO recalls that climate phenomena of natural origin, such as “La Niña” and “El Niño”, are situated in “a broader context of climate change” related to human activities, “which causes global temperatures to rise, accentuates extreme weather and climate conditions and modifies seasonal rainfall and temperature regimes.
