Ocean heat is at record levels, with major consequences

While surface temperatures were about the 6th warmest on record in 2021, the upper oceans were at their hottest – and they’re a stronger indicator of global warming. A top climate scientist explains.

Temperatures in the upper ocean are at record levels, with major consequences

While global surface temperatures were around the fifth warmest on record in 2021, the upper oceans were at their hottest – and they’re a stronger indicator of global warming. A top climate scientist explains why.
