The case for Arctic geoengineering | New Scientist Weekly 269

Could we re-freeze the Arctic… and should we? The Arctic is losing ice at an alarming rate and it’s too late to save it by cutting emissions alone. Geoengineering may be our only hope. A company called Real Ice has successfully tested a plan to artificially keep the region cold - but what are the consequences and will it work on the scale we need?
Octopuses and fish have been found hunting together in packs in an unexpected display of cooperation. Not only do the fish scout out potential prey, they even signal to the octopuses to move in for the kill. And a fish doesn’t prove helpful? They get punched.
The world’s oldest cheese has been found in China - and it’s 3,500 years old. As we get a fascinating look into the fermenting habits of ancient humans, find out how modern day fermentation is being repurposed to help us create biofuels, break down microplastics and more. We hear from Tom Ellis, professor of synthetic genome engineering at Imperial College London.
Our bodies are littered with microplastics - they’re in our livers, kidneys, guts and even our olfactory bulb. How worried should we be? Microplastics have been linked to some pretty serious health consequences - but are they the cause?
Hosts Rowan Hooper and Sophie Bushwick discuss with guests Madeleine Cuff, Michael Le Page and Grace Wade.

And why wouldn't the petro industry be footing at least 50% of the budget for our woes?

[@cedriceric9730]

because they are too busy keeping civilisation running and the world population growing such that illeterate people who dont care how the world works or how modern life is even possible can continue complaining

[@SquawkingSnail]

Can we also devise a way to prevent glaciers and ice from slipping down mountainsides or sliding into the oceans. Tsunami warning system...that kind of thing. Just in case the whole refreezing thing doesn't work.

by show of hands , how many here dont know that their very existance moment by moment is solely because of oil?
