On page 18 of Laurie David's new children's global warming book, there is a glaring scientific error. David tells children:

Deep down in the Antarctic ice are atmosphere samples from the past, trapped in tiny air bubbles. These bubbles, formed when snowflakes fell on the ice, are the key to figuring out two things about climate history: what temperatures were in the past and which greenhouse gases were present in the atmosphere at that time. The more the carbon dioxide in the atmosphere, the higher the temperature climbed. The less carbon dioxide, the more the temperature fell. You can see this relationship for yourself by looking at the graph:

What makes this graph so amazing is that by connecting rising CO2 to rising temperature scientists have discovered the link between greenhouse-gas pollution and global warming.” What really makes their graph “amazing” is that it’s dead wrong. In order to contrive a visual representation for their false central claim that CO2 controls temperature change, David and co-author Cambria Gordon present unsuspecting children with an altered temperature and CO2 graph that falsely reverses the relationship found in the scientific literature.
