Jo Nova has an entertaining article describing the excellent correlation between increasing US Postal charges and rising temperatures through the 20th Century. Joanne humorously claims a causal relation and thus excellently lampoons the IPCCs ridiculous assertion that a similar correlation between rising levels of atmospheric carbon dioxide and rising world temperatures proves that carbon dioxide is causing the temperature rise. Actually, even the claim of a correlation is disputed, since temperatures have gone both up and down while CO2 rises quite steadily.
