Story summary

A review in *Frontiers in Science* evaluates five geoengineering proposals for the Arctic and Antarctic, deeming them unfeasible and environmentally harmful.
The study cautions that these methods may divert attention from crucial carbon emission reduction efforts.
Techniques like stratospheric aerosol injections and sea curtains pose significant risks and costs.
Over 40 researchers assert that achieving net zero emissions is the only viable solution to climate change.
Lead author Professor Martin Siegert emphasizes the fundamental flaws in these well-intentioned ideas.
