A new analysis shows that in 2019 the world’s oceans were warmer than in any other time in recorded human history, especially between the surface and a depth of 2,000 meters (about 6,500 feet). The analysis also shows that the past five years have shown the highest global ocean temperatures and that recent ocean warming is 450 percent greater over the past 30 years than in the 30 year period beginning in 1955.
