Could clouds be the key to slowing climate change? Cirrus clouds trap more heat than other clouds, thus keeping the Earth warmer; if scientists can get rid of them, the Earth might cool down. An eye-opening video delves into three extreme—but possible—solutions to climate change. These include creating designer clouds, fertilizing the oceans with iron for more phytoplankton, and putting sulfur dioxide into the stratosphere.
