Why won't Climate Scientists produce the empirical data that will prove their theory that CO2 is the primary culprit behind Climate Change and shut their critics up once and for all? Answer: The reason they refuse to show any data is because the data does not exist. In fact all the empirical data refutes their theory. So instead of showing the data that would prove their theory they manipulate the data; name call by calling anyone who disagrees with them "deniers" and try and shut people up.
