Billionaire Polluters took the gloves off, threatening Cambridge University with losing a lot of donations if it decides to divest from fossil fuels.

Divesting from fossil fuels is a desperation tactic to try to encourage the decrease of a practice that is slowly but steadily causing global catastrophe, when what we really ought to be doing is blocking all new drilling world wide and steadily reducing what can be extracted from existing wells.

"Engaging" with fossil fuel companies is as useless as negotiating peace with Netanyahu: they extend the discussion indefinitely while continuing to extract profits.

A company proposes to launch satellites to provide continuous real-time surveillance views of the whole surface of the Earth.

How much resolution this will provide is not clear, but it makes me wonder if there is an antisatellite weapon that avoids producing dangerous space debris.

An Israeli member of Parliament tweeted that he wished Ahed Tamimi had been shot rather than jailed. Twitter punished him with a short suspension, but he shows no shame.

The UK's "special forces" have never been scrutinized by parliament, but that may soon change.

Melting ice in Greenland has triggered a positive feedback, releasing dust that darkens the surface so that it absorbs more light and heats up to melt more ice.

A different positive feedback loop is speeding melting of Antarctic ice.

This leads me to think that that forecast sea-level rise is an underestimate. I am not surprised, since the forecasts are based on known phenomena only, and that makes them conservative.

A mere 10 meters of rise would inundate many cities around the world.

Can we dam the Mediterranean Sea? It would be a megaproject and a great challenge, but might be cheaper than protecting, or losing, the heart of every city on its coasts.

It might be necessary to transfer lots of water and/or salt across the dam, but that would be better than letting the Mediterranean flood so many cites.
