“The new math – IPCC version“. Yet another copy-and-paste job from Anthony Watts. This time its an anonymous analysis from a sites.google.com page.
Wisely detaching themselves from their argument, they chose to confuse real-world temperature trends with synthetic sinusoidal data and declare that the IPCC’s Fourth Assessment Report is a lie(!!!!!!) because the synthetic trend changes with the number of cycles that are included.
Well, duh. Of course it’s comical to suggest that the real-world temperature trends are better represented by a synthetic waveform.

Where are the sine waves???
Let us know when you get out of high school, anonymous!
Show all the 5-year intervals, not just the most recent one. That blows away the sine curve idea.
