West Antarctic ice sheet faces ‘unavoidable’ melting, a warning for sea level rise – the Washington Post
Accelerating ice losses are all but “unavoidable” this century in vulnerable West Antarctic ice shelves as waters warm around them, according to new research. And the analysis could mean scientists were too conservative in predicting about one to three feet of sea level rise by 2100…
Greenland’s ice shelves hold back sea level rise. There are just 5 left – the Washington Post
And now there are only five large shelves left, stretching out from their fjords toward the Greenland Sea and the Arctic Ocean. That includes three major ones — Petermann, Ryder and Nioghalvfjerdsbrae (often referred to as 79 North for its location in degrees latitude) — whose respective glaciers could ultimately account for 3.6 feet of sea level rise if they were to melt entirely — a process that would take centuries to play out…

Alarming’ scale of marine sand dredging laid bare by new data platform – the Guardian
One million lorries of sand a day are being extracted from the world’s oceans, posing a “significant” threat to marine life and coastal communities facing rising sea levels and storms, according to the first-ever global data platform to monitor the industry….
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…
Sand mining is a huge problem, a new global map shows – the Verge
People are dredging an alarming amount of sand from the seafloor, the United Nations Environment Programme (UNEP) warned today. An average of 6 billion tons of sand are taken from marine environments every year, according to a new global data platform from UNEP….
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…
DeSantis’s Florida Approves Climate-Denial Videos in Schools – Scientific American
Florida’s Department of Education has approved classroom use of videos that spout climate disinformation and distort climate science
Climate activists are like Nazis.
Wind and solar power pollute the Earth and make life miserable.
