Designed to play on Science On a Sphere, this video explains El Niño and its impact on the marine food web. Wind-driven upwelling in the eastern equatorial Pacific normally lifts nutrients to the sunlit surface to fertilize phytoplankton blooms. El Niño disrupts this pattern, causing famine across the marine food web. A big El Niño is developing in 2015, shown in satellite images of warmer sea surface temperatures and less chlorophyll - the green pigment in phytoplankton.
