‘At first, the idea does sound crazy’: meet the scientists trying to refreeze the Arctic
16 June 2026, Damian Carrington, www.theguardian.com
Arctic sea ice loss has prompted interest in geoengineering approaches aimed at slowing ice decline, including techniques designed to increase ice thickness and extend seasonal coverage. Experiments to refreeze and reinforce sea ice are raising questions about whether such interventions could meaningfully influence Arctic warming, as well as concerns about their feasibility, environmental impacts, and role alongside emissions reductions. Research to rethicken it may be showing early signs of success.
