‘At first, the idea does sound crazy’: meet the scientists trying to refreeze the Arctic
Scientists are testing a geoengineering method to thicken Arctic sea ice by pumping ocean water onto the surface to freeze. Early results show promise in increasing ice thickness, though the broader climate crisis continues to cause rapid melting.
Why it matters
Geoengineering represents a controversial but potentially necessary frontier in the fight against irreversible climate change and sea-level rise.
Sea ice is melting fast, worsening the climate crisis, but a bold attempt to rethicken it is showing early signs of success
The report provides a balanced look at a scientific experiment, acknowledging both the technical success and the overwhelming scale of the climate crisis.
