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

The first heat wave of the year is baking the West: on.wsj.com/45vsisN

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

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

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.

Lets refreeze the artic. *Drives gas powered snowmobile

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

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

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

We should invest in extreme weather proof habitation and agriculture.

One million pumps and one million small wind turbines that have to be installed, moved hundreds of times and finally removed each year.

I know what catastrophics they are dealing with .. 1. It could open a new trade route which could benefit russia by passing through russian water. 2. Russian military expension over the arctic region with vast abundants of oil and gas reserves. 3. Ramp up of military hardware such as icebreaker missile ships by russia in arctic which could disrupt the logistics of eu and usa

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

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.

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.

On a scientific way: 1. The entire arctic winter with solar panels :) 2. As a result, if you operate a pump with a capacity of 1200 liters per minute with 6 liters of diesel oil per hour of operation, and during this time you make 720 square meters of ice on a 10 centimeter thick surface with 72 cubic meters of water, then, right, at 80 degrees latitude, at an average sun height of 10 degrees, the incident sin is 1360 W, solar energy, i.e. instead of 20% of the hard 21 W, the ice reflects 85%, then you can "get rid" of 13 W of solar energy per square meter, i.e. 720 square meters is almost 10 KW! Which is not nothing, because a summer's day gives back the energy put into it, from then on it's a net profit. Since we calculate that the heating effect of the carbon dioxide pushed into the air by an internal combustion engine (very average) is 10,000 times the energy used in the engine, it is easy to calculate that in just 25 years the operation is already profitable or not... With a simple working example (like under covid) close the factories and travel by bike, go hiking and grow a garden!

How much for enough stratospheric SO2 to cool the artic by a couple degrees for a couple of years?

You don't need diesel generators. Just use a load of ram pumps. They run themselves without needing continuous energy. They can't pump a lot of water. Surely a ram pump can be utilised in some way

Commendable effort, thank you.
