Environmental Defense Fund: Our position on geoengineering
„Deliberate climate interventions such as albedo modification should not be undertaken for the foreseeable future as they present serious ecological, moral and geopolitical concerns.“

„In 2016 an interdisciplinary team of scientists from Arizona State University suggested as a means to combat global warming that millions of windmills be erected in the Arctic Ocean. These mills would drive pumps that would lift seawater onto the remaining Arctic sea ice where it would turn into new ice that would help restore the power of the Arctic sea ice to reflect solar radiation.“
„To prevent the impending doom that awaits Earth through global warming, three young geo-engineering enthusiasts have offered a simple and cost-effective solution — freeze sea water to rebuild polar ice caps.„

„Enhancement of the Earth’s albedo through the injection of sulfate aerosols into the stratosphere has been proposed as an approach to offset some of the adverse effects of climate change. Here we analyse an ensemble of simulations of the twenty-first century climate designed to explore a strategic geoengineering approach. Specifically, stratospheric sulfur injections are imposed at 15° and 30° in both hemispheres with the aim to minimize the changes in surface temperature, both in the global mean and in its gradients between hemispheres and from equator to pole.“

„In his article “Geoengineering worsen climate and hurts Paris Agreement” (October 11, 2018, posted online October 15, 2018), Fiu Mataése Elisara, Executive Director – O.L.S.S.I contends geoengineering[nbsp] (climate engineering) ‚…is a deliberate attempt by the rich to distract from the real priorities of fossil fuel emission reductions. A false mitigation solution that will worsen climate change and indeed does nothing but hurts the Paris Agreement.'“
„Scientist says giant walls and cooling tunnels may be the best ways to save polar ice.“

„In this paper, a novel localized surface albedo modification technique is presented that shows promise as a method to increase multi‐year ice using reflective floating materials, chosen so as to have low subsidiary environmental impact. Detailed climate modeling studying the climate impact of such a method reveals more than 1.5 °C cooler temperatures over a large part of the Arctic when simulating global sea ice albedo modification. In a region north of Barents and Kara Seas temperatures have been reduced by 3 °C and in North Canada by almost 1 °C. Additionally, there are notable increases in sea ice thickness (20‐50 cm Arctic wide) and ice concentration ([gt]15‐20% across large parts of central Arctic). These results suggest that the geoengineering technology proposed in this study may be a viable instrument for restoring Arctic ice. „
„Yes, you read that correctly: A team of scientists and engineers[nbsp]is calling for a massive seawall[nbsp]to directly slow sea level rise by preventing glaciers from sliding off into the ocean in large chunks.“
„Previous discussions of geoengineering have looked at global projects, like seeding the atmosphere with particles to reflect more sunlight. That’s what makes this focused approach more feasible, said Michael Wolovick, a postdoctoral research associate in Atmospheric and Oceanic Sciences at Princeton University and a co-author on the Comment.“
