Global climate change: How much is the ocean warming by?

The document highlights a consistent upward trend in global ocean surface temperatures since the 1980s, noting that 2020 temperatures were 0.76 degrees Celsius above the 20th-century average. It identifies 2016 as the year with the highest recorded divergence at 0.79 degrees Celsius and warns that continued warming will intensify extreme weather events.

• Global ocean surface temperatures have shown a consistent upward trend since the 1980s when compared to the 20th century (1900-1999) average. In 2020, these temperatures were 0.76 degrees Celsius higher than that average, based on data from the National Oceanic and Atmospheric Administration (NOAA).
• The highest recorded divergence in ocean temperatures occurred in 2016, when temperatures were 0.79 degrees Celsius above the 20th-century average.
• Ongoing global warming is expected to alter the duration, frequency, spatial extent, and strength of extreme weather events.
