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…

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…

The land near the mouth of the Mississippi River is barely land at all. Muddy water forks into a labyrinth of pathways through a seemingly endless expanse of electric-green marsh grass, below skies thick with birds. Shrimp and crabs wriggle in the water below, and oak and cypress sprout from wet soils on higher grounds. Stretching for more than a hundred miles along the coast of Louisiana, this is one of the world’s largest, and most famous, river deltas…

Before the flood: how much longer will the Thames Barrier protect London? – the Guardian

The last time the Thames broke its banks and flooded central London was on 7 January 1928, when a storm sent record water levels up the tidal river, from Greenwich and Woolwich in the east as far as Hammersmith in the west. Built on flood plains, the capital was defended only by embankments. The flood waters burst over them into Whitehall and Westminster, and rushed through crowded slums. Fourteen died and thousands were left homeless…
