(Ocean/Climate Change) This chart shows how much the ocean is warming (Katharina Buchholz, WEF)

In 2020, global ocean surface temperatures were 0.76 degrees Celsius higher than the average temperature for the past one hundred years.
While the annual divergence fluctuates, with some years hotter and others cooler, there is a definite upward trend, visible in the data.
Continuing global warming is set to increase the strength, frequency, spatial extent and duration of extreme weather events.
