Plenty of holes are being poked in the Global Warming alarmists' arguments here. I've always thought it was idiotic to use computer modeling, which demonstrably doesn't work even in the short term, to make a guess about planetary temperatures even a year or two ahead, but that's just me. Some of the points being made in the article linked above:
The average global temp hasn't risen in seven years and is actually down this year; the earth's Southern hemisphere hasn't warmed in 25 years; many areas, including the earth's oceans, are demonstrably cooling; Greenland's ice is growing, as is that of the polar ice caps; and most important of all, those who study the history of the Earth's climate agree that violent temperature changes have been going on for millenia, and will continue to do so. Which means that attributing such changes in our own time, assuming they actually exist, to human activity is just stupid. Spending time, money and effort on reversing such climate changes is even more so.
