The United Nations Environment Assembly this week considered a resolution on solar radiation modification, which refers to controversial technologies intended to mask the heating effect of greenhouse gases by reflecting some sunlight back to space.
Proponents argue the technologies will limit the effects of climate change. In reality, this type of “geoengineering” risks further destabilising an already deeply disturbed climate system. What’s more, its full impacts cannot be known until after deployment.
The draft resolution initially called for the convening of an expert group to examine the benefits and risks of solar radiation modification. The motion was withdrawn on Thursday after no consensus could be reached on the controversial topic.
