The world blurred behind her as she applied the signature pink, brightening everything about her.

Researchers are studying two kinds of solar radiation management: marine cloud brightening and stratospheric aerosol injection.

Marine cloud brightening involves spraying very fine saltwater from a boat towards low-level clouds above the ocean to enhance their brightness and reflectivity.

“Brightening the cloud off the coast of Namibia could induce drought over South America and particularly Brazil. What's in Brazil? Well, the rainforests,” Prof Haywood said.

While there is focus on using marine cloud brightening to offset global temperature rise, some see an opportunity to use it on a much smaller scale.
