Extreme ocean changes due to climate change are not an abstract or future scenario. This summer alone, 23 per cent of the world’s oceans experienced a heat wave, corresponding to an area roughly equivalent to the entire Atlantic Ocean.
Those extreme events, against a backdrop of more gradual global warming, have widespread effects on ocean life and their environments. For example, some species might leave their preferred environment in favour of more suitable temperatures, others might adapt locally or go extinct.
