There is a common type of cloud called a stratocumulus, that forms into low, fluffy blankets. These blankets of cloud cover large parts of the globe, reflecting lots of sunlight and heat, and helping to keep the planet cool. In 100 years these clouds could be gone. One team of scientists found that, if CO2 levels continue to rise, eventually stratocumulus clouds won't be able to form at all. They'll become extinct. And without the shade these clouds provide, the planet will heat up faster than ever before. Computer predictions are helping scientists make the argument so we can act now and save our planet... and its clouds.
