As the world attempts to tackle the effects of climate change, scientists are proposing some radical new ideas to cool the planet. From fleets of airplanes spraying sulphur dioxide gas into the stratosphere to dim the sun's rays, to deploying thousands of ships that spray sea salt to thicken clouds to reflect more sunlight away from Earth, researchers are developing some extreme ways to combat our warming world.  Ideas that were once considered science fiction are now actively being researched as ways to cool the planet. Apocalypse Plan B delves into some of these ideas for artificially trying to cool the earth. Critics argue that this kind of "geoengineering" risks mass flooding, droughts, or ultimately an era of international climate wars among nations.  Apocalypse Plan B is a riveting journey into the near future, with bold ideas, rich animation and vibrant debates as two visions of humanity's future collide.
