The El Niño weather pattern in the tropical Pacific influences weather across the planet. As the planet warms, it is unclear if El Niño will grow stronger, bringing more extreme floods and droughts to some regions, or if El Niño will slacken, creating more uniform weather. Scientists aboard the Lamont-Doherty ship, R/V Langseth, will sample ancient sediments from the central Pacific Ocean to see how El Niño and climate varied in the past, and how they may change again in the future.
