Record-Breaking Sea Temperatures Amid El Niño

Marine heat waves are now affecting 42 percent of the world’s oceans. This is occurring as a strong El Niño develops in the Pacific. The combination has led to a notable shift in ocean temperature records globally.

The Copernicus Climate Change Service reports a rise in average global sea surface temperatures. Recent data indicates that temperatures have climbed to almost 70 degrees Fahrenheit late last week. This spike could mark the first time in thousands of years for such high levels.
