TIL about a memorial ceremony in Iceland in 2019 to mark the end of a glacier, changing the place name from Okjökull to Ok (jökull = glacier). Uncompromising wording on the bronze plaque:
"This is to acknowledge that we know what is happening and what needs to be done. Only you know if we did it".

Bronze plaque saying "A Letter to the Future. Ok is the first Icelandic glacier to lose its status as a glacier. In the next 200 years all our glaciers are expected to follow the same path. This monument is to acknowledge that we know what is happening and what needs to be done. Only you know if we did it. August 2019. 415ppm CO2"

All you need to know about Bill Gates' long-standing and misguided take on climate change.
'The solution to the climate crisis isn’t going to come from the fairy-dust-sprinkled flying unicorns that are the “benevolent plutocrats.” They don’t exist.'

Michael Mann to Bill Gates: You can’t reboot the planet if you crash it

What Gates is putting forward aren’t legitimate arguments that can be made in good faith. They are shopworn fossil fuel industry talking points.

1. More Americans work at the Cheesecake Factory than in the entire coal industry, and that won't change. It's because of automation, not snooty libs.

2. Coal energy is now more expensive than wind and solar.

3. So this means: higher energy prices, more pollution, no jobs benefit. Genius!

Energy Secretary Chris Wright on Fox: "We're announcing today expanded programs to help the American coal industry. We're helping it because for years it has been under assault. It was out of fashion with the chardonnay set in San Francisco, Boulder, and NYC ... coal just makes the world go round."

Setting aside the absolute scientific idiocy of the specifics here, reflect for just a moment on the fact that there's a list of "banned words" at all.
That's fascism and unAmerican.
