If Bill Gates‘ plan to block the Sun’s rays from reaching Earth wasn’t already insane enough, a team of scientists is now planning to help his efforts with a new “geoengineering technique” to completely dehydrate the stratosphere, stripping it of all its water vapor. Water vapor is important to Earth. Not only does it trap heat from the Sun, making the planet liveable, but its complex molecules also absorb heat radiated from Earth’s surface, re-radiating it back to the planet.
