Bill Gates Backs Solar Geoengineering Experiment to Cool Earth

Bill Gates is backing the first high-altitude experiment of one radical

climate

change solution, creating a massive chemical cloud

that could cool the earth.

It's called solar geoengineering, and it's highly controversial.

How long will it be that countries keep experiencing these

climate impacts before someone gets desperate and says, "Hey, we need

to cool the planet with solar geoengineering"?

It would look something like this.

Thousands of planes would fly very high and use nozzles to inject millions of tons

of light-reflecting particles into the stratosphere.

It would create a thin chemical cloud of those particles around the whole planet,

blocking some sunlight from reaching the surface.

It would mimic a giant volcanic eruption, which we know cools the earth.
