Clouds Warm and Cool the Earth and CO2 is Major Plant Food

Water is the greatest greenhouse gas. Clouds warm and cool the earth. And CO2 is a major plant food.

North American temperature has increased a little over the last 100 years. Because winters are less cold, fall and spring are a bit longer and a bit milder than a 100 years ago. According to NASA, clouds both warm and cool the earth. NASA expects more clouds in the future, yet aren’t completely sure. And, CO2 is major plant food.

The greener it is, the more plants have grown in there, between 1982 and 2015. Our world is 10% greener than it was a decade ago. CO2 is major plant food.
