We most likely already emitted enough carbon dioxide to kill all glaciers worldwide. Regions who depend on glacier melt for their water supply need to act now.

Instead many are doing the opposite: https://www.cbc.ca/news/canada/calgary/renewables-pause-albe...

Does Alberta or Canada depend on glacier melt for their water supply?

Edmonton and Calgary definitely do. Calgary in particular could be in trouble, depending on the Bow glacier, which is receding rapidly.

half the world relies on water from the Himalayas and the tibetan highlands. China, SEA(Vietnam, Laos, Cambodia, Thailand Myanmar) and South Asia all rely on glacial water for large scare agriculture

And they all have nukes. All the more important that they do something now that doesn’t involve a war over resources.

Act now how?

If glaciers don’t store water for you, you need to do it yourself for example by building reservoirs

The only issue is pretty much all the good sites for a reservoir already have a reservoir by now. Whats left is expensive stuff like digging out underground reservoirs that you can imagine would take national support for a lot of places to achieve.

Having no water is even more expensive.

The oceans store plenty of water, we will just have to extract the salt. Ya, and build more reservoirs, poorer countries are going to get hit really hard.

Sun automatically extracts salt-free water via evaporation, then the vapor is conveniently carried by winds all over the world and literally rains from the sky.

But without vastly overengineered projects, how would we find out about the massive geniuses like Elon Musk among us? /s

You don’t even need that. Just look at Tokyo’s sewer system with huge cavernous water storage to avoid flooding.

But can we build enough reservoirs to store evaporated water? It seems like desalinization will still be important.

But first get a refrigerator on Mount Everest to freeze the water. /s

Yes. And the rest just sell CO2 certificates, eat popcorn and enjoy the drama. /s

At this point with the way political will is structured on this planet, the most direct way might be to overlay a satellite map of industrial emissions, drop leaflets to tell people not to show up to work, strike these targets, then argue you had no choice in front of the UN.

Well that's one way to end up dying in a nuclear holocaust.
