Carbon dioxide: nature's tiny solar panels

Carbon dioxide: nature's tiny solar panels

Carbon dioxide, like chocolate, is a good thing in moderation.  Without carbon dioxide gas in our atmosphere, life as we know it could not exist.  This is because carbon dioxide molecules are nature’s own tiny solar panels—absorbing, retaining and re-emiting heat from the sun. 

However, as the concentration of carbon dioxide increases, the atmosphere is able to retain more and more heat, with consequences for life on our planet.
