Didn't they stop trying at some point because they didn't want him to be replaced by someone competent?

As I understand it: because not enough people will use it through these ways, leading to not enough motivation for the dev(s?) .

Super green!

the storm surge could be up to 15 feet

It's probably because of the last sentence. Which technically is a fact (because they obviously think that), but 5m is something at least cities in northern Germany are usually prepared for.

I'm not sure how exactly the tides are measured and if it differs internationally, but we have floods at around 5m every few years without any significant damage (German source). Hamburg had a flood with 6.45m in 1976 without damage to the city (only the port and other parts outside the levees were obviously damaged; German source).

but an order of magnitude smaller

I'm pretty sure that would be three orders of magnitude.

Most people’s ELOs don’t shift much after settling into your “natural” rank, which should happen after about 50 matches or so.

Ehm, 50 matches seems like a lot to me. Especially if they aren't enjoyable (yet) because of flawed matchmaking.

I guess this really depends on where you live. Germany at least has rather strong protections for patients. We had a case last year in our town of a woman with ~40 suicide attempts who would still not be held against her will (German source). So please get help if you feel you need it (and get informed about your rights).

the forecasted severity of those risks in the future

I understand that as changes in risk severity due to the climate catastrophe. Climate used to be kinda stable (at least over a human life time).

The service isn't. The fact that it is needed/useful is.
