#10. Geo-engineering
It used to be considered the stuff of science fiction, but a growing
number of experts are voicing qualified support for a radical solution to
climate change. It's called geo-engineering, and it involves purposefully
attempting to cool the climate through planetary-scale actions like blocking
sunlight by stationing mirrors in space. Other fixes include seeding the
seas with iron to help plankton absorb more greenhouse gases, and injecting
sulfur into the upper atmosphere to create sunlight-deflecting clouds. These
are clearly last resorts, and scientists have no idea whether the cure could
be worse than the disease, but the very fact that experts now support
researching into geo-engineering shows just how desperate the climate crisis
has become.
