If you want to understand global heating, you have to measure and examine ocean warming trends

• Climate crisis: record ocean heat in 2020 supercharged extreme weather

As if 2020 could get any worse, the latest research showed that oceans hit their highest recorded temperatures, a record that keeps getting broken year after year.

Why are the oceans so important? It is quite simple: almost all of the extra heat we gain because of greenhouse gases ultimately ends up in the oceans. In fact, the oceans absorb more than 90% of the excess heat. Consequently, if you want to understand global warming, you have to measure ocean warming.
