Greenland’s ice shelves hold back sea level rise. There are just 5 left – the Washington Post

Ice accelerating as it flows towards the coast creates heavy crevassing near the coast of Melville Bay in west Greenland (by John Sonntag/NASA’s Operation IceBridge courtesy of NASA Earth Observatory, public domain).

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…

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…

Wind and solar power pollute the Earth and make life miserable.

Recent global and local heat records reflect natural temperature cycles.
These are some of the themes of children’s videos produced by an influential conservative advocacy group…
