6 billion tonnes of sand taken annually from oceans, causing irreparable damage to benthic life – Down to Earth
Some six billion tonnes of sand is being extracted annually from the floor of the world’s oceans, causing irreparable damage to benthic life, according to a new global data platform on sand and other sediment extraction in the marine environment.
The new data platform, Marine Sand Watch, has been developed by GRID-Geneva, a Centre for Analytics within the UN Environment Programme (UNEP). It is available at: https://unepgrid.ch/en/marinesandwatch…

Hurricane Idalia’s Explosive Power Comes from Abnormally Hot Oceans – the New Yorker
Of all the astonishing facts about our blithe remaking of the world’s climate system, the most astonishing might be this: if oceans didn’t cover seventy per cent of our planet, we would have increased the average temperature to about a hundred and twenty-two degrees Fahrenheit. That’s because those oceans have absorbed something like ninety-three per cent of the extra heat trapped by the greenhouse effect and our burning of fossil fuels…
How sea level rise made Idalia’s storm surge worse – the Washington Post
In mid-November 2021, a great storm begins brewing in the central Pacific Ocean north of Hawai‘i. Especially warm water, heated by the sun, steams off the sea surface and funnels into the sky.
A tendril of this floating moisture sweeps eastward across the ocean. It rides the winds for a day until it reaches the coasts of British Columbia and Washington State. There, the storm hits air turbulence, which pushes it into position—straight over British Columbia’s Fraser River valley….
