Soaring ocean temperature is 'greatest hidden challenge of our generation'
A ‘truly staggering’ rate of warming is changing the behaviour of marine species, reducing fishing zones and spreading disease. The ocean has absorbed more than 90% of the extra heat created by human activity. If the same amount of heat that has been buried in the upper 2km of the ocean had gone into the atmosphere, the surface of the Earth would have warmed by a devastating 36C, rather than 1C, over the past century.

The oceans are heating up. That's a big problem on a blue planet
The extra heat that our greenhouse gases trap is actually absorbed by the oceans. That means that the upper few meters of the sea have been steadily warming more than a tenth of a degree celsius per decade, a figure that’s accelerating. When you think of the volume of water that represents, and then try to imagine the energy necessary to raise its temperature, you get an idea of the blowtorch that our civilization has become.
