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.

The EPA has declared that burning wood is carbon-neutral.

In a stable climate, it would be carbon-neutral if done at a sustainable rate over a long time. However, we can't assume that another tree will actually grow to the same size -- not when logging is used for deforestation. But even if another tree starts to grow, it might not reach maturity. Global heating could dry up the region, or allow pests to migrate which would kill that tree.

New Jersey has adopted a strong law to put an end to the widespread inequality of pay that women suffer.

Kenya banned plastic bags 100%, and the effect has been a tremendous improvement, but some edge cases are doing harm in specific activities.

Does the ban include long-lasting plastic bags meant for reuse? I carry a few of those with me, and I have used them dozens of times, Forbidding those would seem to be defeating the purpose. Only a few rich people would buy a bag like that and use it just once.

The Tories have been quietly cutting government staff concerned with climate safety since 2016.

Saboteur Pruitt has been doing the same thing since 2017 but in a very visible way.
