>>The world’s oceans were warmer in 2019 than at any time in recorded history, a new analysis confirms.
The past five years all set records for the highest average annual ocean temperatures, with last year continuing the trend upwards.
“It is important to note that ocean warming will continue even if the global mean surface air temperature can be stabilised at or below 2 degrees C.”
Around 90 per cent of climate change energy is stored in our oceans, according to Professor Abraham.
“You cannot really measure global warming unless you measure ocean warming,” he said.
“I like to say ‘global warming is ocean warming’, since the oceans absorb so much heat and are huge, it makes ocean measurements less noisy than air temperatures.”
They also estimate the rate of warming during the period between 1987-2019 was 450 per cent greater than the prior 30-year period from 1955 to 1986.
The warming has been particularly pronounced in the upper 2,000 metres of the ocean, with the top 300 metres accounting for about 41 per cent of the increase.
Although warming was distributed across the world’s oceans, it was more pronounced in the Atlantic and Southern Ocean, where several severe marine heatwaves have also been recorded in recent years.<<
