The world is entering an era of “water bankruptcy.” 💧 😪

People are now using so much fresh water amid the consequences of climate change that we're in an era of water bankruptcy, with many regions no longer able to bounce back from frequent water shortages. ⬇️

The world is entering “water bankruptcy,” UN researchers warn — draining rivers, aquifers and glaciers far faster than nature can replace them.

With 4 billion people already facing seasonal water scarcity, scientists say the crisis is now one of irreversible damage, not shortage alone.

3/ But that's simply not true. CS/tech has a number of features that are completely unlike those in every other field.

Sometimes, other fields can learn from CS/tech. more often, CS/tech needs to STFU and listen to other fields.

The UK government didn't want you to see this report on ecosystem collapse. I'm not surprised | George Monbiot It took an FOI request to bring this national security assessment to light. For ‘doomsayers’ like us, it is the ultimate vindication, says Guardian columnist George Monbiot

Please spread this far and wide, as stories don't get much bigger than this. When the government blocks even the intelligence services from telling us we're heading for environmental catastrophe, you know we have a problem. A very big problem.
Thank you.

A Truth is a post that you share to those following you. A Truth can be a comment, image, or video and can contain links to other content. Using Truths on Truth Social you can share your thoughts, photos, videos, memes, links, and more. You’ll quickly get the hang of it!

Dans ce contexte-ci, je ne pense pas que Mark Carney utilisait "truth" dans le sens de vérité, mais plutôt pour désigner les commentaires sur Truth Social: help.truthsocial.com/truth-social...

I am a climate scientist and this is correct.

As the planet warms, storms like the one today are getting stronger… and as the Arctic is warming twice as fast as the mid latitudes, it increases the risk of the “freezer door” swinging open.

I'm currently looking for an MSc student to characterize water ages and storage in cold catchments. Several potential projects available, and I will support students who want to develop their own! If interested, please reach out soon at akgrewal@usask.ca, as Sept 2026 app deadlines are approaching!

None of this talk about a brain gain makes any sense unless funding for research is dramatically increased across the board in Canada.

The way to make Canada a top global science leader is to a) prevent brain drain, and b) make it a go-to for the best researchers from around the world. You do this by having very robust, stable, and internationally competitive funding across the board -- not by huge one-time recruitment efforts.
