Geoengineering is a contentious topic always but thickening ice seems to have few downsides. From the article
>Real Ice is trying to thicken seasonal ice so it lasts longer into the warm months, keeping the planet cool. Sherwin hopes pumping could someday refreeze a million square kilometers of both seasonal and multiyear ice—an area the size of Texas and New Mexico combined and about a fifth of what’s now left in summer—to stop the ice cap’s death spiral. All it would take, Real Ice says, is half a million ice-making robots.
This is absolutely, utterly wrong.
If you want to increase the Earth’s albedo, for a teeny tiny fraction of the cost of this arctic monstrosity, and without the risk of huge environmental damage caused by a lot of technology and fuel and batteries sunk by arctic storms…
Just put vast arrays of mirrors over the equatorial deserts. The sun is a lot more direct there anyway. Mirrors are hella cheaper than freezers and require almost no maintenance.
