Inside the Extreme Plan to Refreeze the Arctic | WSJ Future of Everything

A method normally used to create ice-skating rinks is now coming to the rescue of melting sea ice in the Arctic. Since satellite records began in 1979, summer Arctic sea ice has shrunk by around 13% per decade. Could making more ice be a potential solution to this issue?

WSJ got exclusive access to follow the team trialing the technology in the Arctic island of Svalbard, one of the coldest inhabited places in the world.

Every once in a while when it gets too hot we just drop a giant ice cube in the ocean

[Mridul.scentman]

People who are criticising this effort should know that
For every big project, small trial run is needed to see if they are going on a right track. They just can’t pour billions of dollars and indulge in this huge process without experimenting.

Didn't know Jürgen Klopp already found a new job.

Me opening my fridge 24/7 to cool down earth: I'm doing my part

[souravjaiswal-jrbj]

Yesterday my grandpa (age 85) said that summer has gotten worst both in absolute temp and humidity in Kolkata in last 10 years. He has not knowledge of science or climate change, pure observation.

Exactly the type of plan that the Wall Street Journal would support.

For a long time, I imagined what would happen if salt made from seawater was sprinkled over Antarctica.
When salt comes into contact with the snow on the surface, its melting point drops, so it turns into water, but if the surrounding area were colder, I wonder if it would freeze like a flat mirror.
I had no idea of spraying seawater directly, but I hope it will be successful.

Lets refreeze the artic. *Drives gas powered snowmobile

[MirceaKitsune]

Impressive, but I have a method that's far more realistic by comparison: Throw a bottle of water in the freezer for an hour, put it in your pocket, board the fastest plane to Antarctica, get on a bus to a city close to the target, after that take a snowmobile to the glacier, then spill the bottle on the ground... simply return to your continent and repeat the process. If enough people do it then it's bound to work, because human ingenuity has no limits and will always save the day somehow!

7:53 Really? Harder challenges than restoring the Arctic? Who did they worked for? Space aliens?

[vejovim]

If we just generate ice in ice cube factories powered by coal, we can ship it up there and, eventually, there'll be enough ice that the Arctic will cool back down.

The problem is Russia and China want to open up the sea routes in the artic.

[MISTERLeSkid]

A team of people thickening a couple of football fields that they just drive-up on their skidoos from land? How many millions of people will need to drill and flood the millions of football fields of ice in the arctic, which is thousands of miles from any land? It's a lovely theory but in no way practically feasible.

[xforce]

Unfortunately, this may help, but it's merely addressing a symptom of the problem. If we actually want to prevent the Earth from warming at alarming levels, we must reduce the amount of CO2 emissions that we emit into the atmosphere.

[pabf]

Y cuando no hay placa de hielo, qué hacen? bombean agua sobre el agua?

[AndreaDoesYoga]

Mind-blowing solution, let's refreeze the Arctic! ❄️

[charlesd]

Nuclear Micro-reactors would be a great energy source for these projects

[lineinthesand]

It costs more energy to make ice than to not.

[zettaiengineer]

summary: the heat in liquid seawater that is nominally insulated by sea ice is surfaced so that it can be radiated into space, resulting in ice(heat) that would otherwise not be formed(be rejected to space). essentially an ice machine(heat pump) with a condenser that uses the of coldness of space and the atmospheric window.

Wow, is literally along the lines of what was depicted in an matrix/matrix prequel where depicted reflecting the sunrise away from earth.
