A proven process: limestone dosing has already been used to restore river ecosystems damaged by acidifcation – but it could be an extremely powerful carbon capture tool as well

Environment

Cheap, scalable carbon capture method also rejuvenates rivers

A technique originally developed to combat acid rain has the potential to pull an enormous amount of carbon dioxide out of the atmosphere – while helping to deacidify oceans, restore rivers and boost biodiversity and fish populations.

It would be technically possible, and indeed remarkably cheap, to re-freeze the Arctic and Antarctic and halt or reverse sea level rise, suggests new research. But this little guy's not likely to enjoy it

Environment

"Relatively low cost" plan would cool the Earth's poles by 2 °C

New research suggests that cooling the poles by 2 °C, and re-freezing the Arctic and Antarctic, is "feasible at relatively low cost with conventional technologies," if humanity agrees that a rising sea level is worse than this plan's side effects.

MIT scientists have conducted a climate study, finding that extratropical storm tracks seen in blue would change significantly through solar geoengineering

MIT study explores how solar geoengineering would alter the climate

A new study from MIT looks at the consequences of solar geoengineering, exploring some of the flow-on effects of such a move and finding that it could weaken storms, destabilize ice sheets and lead to more polluted urban areas.

A new study claims that stratospheric aerosol injection to combat climate change is practically achievable and economically feasible

Environment

New study examines practicality of spraying aerosols into the atmosphere to combat climate change

Putting aside the issues of should we or shouldn't we, or the prospects for success or failure, would spraying aerosols into the atmosphere in an attempt to combat climate change even be practically achievable? A new study says yes.

A new study suggests launching particles into our atmosphere to mimic the cooling effects of volcanic eruptions could cause climate chaos around the world

Environment

The geoengineering debate: Can imitating volcanic eruptions combat climate change?

With the once controversial idea of battling climate change through geoenginnering slowly gaining popularity, new research from the University of Exeter offers evidence that this untested approach could result in climate chaos.

Study finds sunshade geoengineering could improve crop yields

A new study examining the effects of sunshade geoengineering has concluded that such an approach would be more likely to improve food security than threaten it.
