Not only is the Kyoto Protocol technically flawed, the so-called science behind it is utter twaddle. Never mind complicated things like non-linear mathematics or, indeed, mathematics of any sort. The alarmists can't possibly know how to predict the future of Earth's climate because they can't explain its past.
At one point the UN's famous Intergovernmental Panel on Climate Change tried to tell us the climate story was pretty simple. Their infamous "hockey stick" graph showed temperature constant for 1,000 years, then shooting up sharply in the 20th century as Industrial Man started pumping CO2 and other GHGs into the atmosphere. On top of the technical jiggery-pokery, this account brazenly misrepresented the past.
