[00:03] do we need to keep an eye on it? First, we need to understand trade winds. They east to west. In the Pacific Ocean, they help transport warm surface water to subsurface water to flow towards South [music] America. But every two to seven
[00:17] years, the Pacific plays a Uno reverse card. As a result of a complex interplay between atmospheric pressure and ocean surface temperature, the trade winds warm water sloshes back to the eastern Pacific. If the average temperature of
[00:30] the local sea surface changes by more than 0.5° C, it's called an El Nino event. In South America, El Nino leads to warmer ocean water and heavy rains, while Asia and Oceania experience an increased [music] risk of droughts. Due
[00:43] to climate change, ocean surface temperatures have already risen 0.9° C since pre-industrial times. With El Nino adding even more surface heat, the worse, eventually reducing the ocean's ability to absorb CO2. Bad news for an
[00:57] ability to absorb CO2. Bad news for an already warming planet.
