It's amazing how a little disinformation thrown onto the internet can proliferate so broadly. That disinformation has been thrown out there by scientists with dubious connections to climatology and definite connections to the oil and coal industry. In fact, "Big Oil" has actually been paying (mostly industry) scientists to publish work which denies global climate change.

Global Warming deniers...you've been snookered. Oil & coal companies put this stuff out there to protect their profits, regardless of the truth.

ALL of the papers compiled within the IPCC report are peer-reviewed:

Read the actual report. It answers all the questions about variability of the sun's radiation, past climatic fluctuations, temperature measurement regimens (urban heat island), etc. All that smokescreen stuff which was thrown out by the oil companies is answered here.

Want more peer review? Here's a report requested by Congress and issued last year by the National Academy of Sciences:

As peer review goes, it probably doesn't get much more complete or distinguished than the Nat'l Academy of Sciences.

Al Gore got some stuff wrong on "An Inconvenient Truth". He was operating off of earlier studies...some study results which were later discounted as being too alarmist & too fast (mainly Greenland Ice Sheet melting). But his persistent drumbeat may actually be bringing the truth rising to the top. For bringing the issue forward in this truly global matter, the Nobel Peace Prize is entirely appropriate.

Here are a couple of new links, too...and they're about actual climatolologists, not oil industry shills:
