Examining the cancelled 2011 SPICE solar geoengineering test in the UK, highlighting how regulatory gaps, public opposition, and patent disputes halted early stratospheric aerosol research.
Researchers in Cambridge Bay, Canada, experimented with spraying seawater onto existing sea ice to thicken it. The treated ice grew significantly thicker and remained more reflective, showing promise for combating Arctic sea ice melt, though large-scale application faces significant challenges.
The article reviews five historical geoengineering proposals, from Herman Sörgel's Atlantropa plan to Soviet attempts to modify nature and Project Znamya's "second moon." These ambitious, often absurd, ideas highlight humanity's long-standing desire to reshape the planet, with current scientists considering technological interventions for the climate crisis.
Geoengineering, particularly solar geoengineering, is presented as a risky techno-optimistic "quick fix" for climate change. Critics argue it masks warming, poses termination shock risks, requires centuries of maintenance, and lacks scientific understanding and governance, diverting resources from decarbonization.
Researchers are testing a geoengineering method in Cambridge Bay, Canada, to refreeze Arctic sea ice. The Real Ice project pumps ocean water onto the ice surface, thickening it and reflecting more sunlight. While controversial, it's a research effort to explore potential solutions to climate change.
A UK-funded geoengineering experiment in Cambridge Bay, Canada, is pumping ocean water onto sea ice to thicken it and combat rapid melting due to climate change. The "Real Ice" project aims to test the feasibility and safety of refreezing Arctic ice, with potential benefits for local communities and global climate.
