No time for comment now, but saw this long article worthy of reading.
The above is a great article (via Greenie Watch) that does an excellent job of illustrating the Hockey Stick debate (see my posts below as well).
Given that today the Kyoto Protocols take effect, it would also be wise to consider what Kyoto really is: a wealth transfer from the rich nations to the poor. The countries who have the most, and pollute the most are being asked to spend billions of dollars to clean up, while the poorest nations can continue to pollute. The root of the debate about global warming, at least politically, is money.
