The commission warned:
In the context of accelerated global warming, deliberate large-scale intervention in the Earth's natural systems (referred to as "geoengineering"), such as solar radiation modification, is attracting more attention. However, the risks, impacts and unintended consequences that these technologies pose are poorly understood, and necessary rules, procedures and institutions have not been developed.
Some of these risks include:
These technologies introduce new risks to people and ecosystems, while they could also increase power imbalances between nations, spark conflicts and raises a myriad of ethical, legal, governance and political issues.
Meanwhile, scientists from Harvard University have called for "spraying tiny particles called sulfate aerosols into the atmosphere to reflect away sunlight." And MIT recently wrote, "Geoengineering might be our final and only option."
Speaking to reporters this week, Frans Timmermans, the European Union climate policy chief, said, "Nobody should be conducting experiments alone with our shared planet" and "This should be discussed in the right forum, at the highest international level."
