Oceans are heating up at a quickening pace: study
- The world’s oceans are heating up at an accelerating pace as global warming threatens a diverse range of marine life and a major food supply for the planet.
- About 93% of excess heat — trapped around the Earth by greenhouse gases that come from the burning of fossil fuels — accumulates in the world’s oceans.
- The latest report relied on four studies, published between 2014 and 2017, that gave more precise estimates of past trends in ocean heat, allowing scientists to update past research and hone predictions for the future.
- A key factor in the more accurate numbers is an ocean monitoring fleet called Argo, which includes nearly 4,000 floating robots that “drift throughout the world’s oceans every few days to measure the ocean’s temperature, pH, salinity and other bits of information as they rise back up,”
