From World Climate Report:

The authors place the recent warming into an interesting perspective noting "the global warming observed during the latest 150 years is just a short episode in the geologic history. The current global warming is most likely a combined effect of increased solar and tectonic activities and cannot be attributed to the increased anthropogenic impact on the atmosphere.

Humans may be responsible for less than 0.01°C (of approximately 0.56°C (1°F) total average atmospheric heating during the last century)". Holy cow, can you imagine the letters and e-mails they must have received in response to that conclusion? They even show that over the last 3,000 years, the earth has cooled, or if you look just at the last 1,000 years, the earth has been cooling as well (the earth was in the Medieval Warm Period 1,000 years ago).

Their conclusions with respect to potential policy will more than raise some eyebrows as well as they write "Any attempts to mitigate undesirable climatic changes using restrictive regulations are condemned to failure, because the global natural forces are at least 4-5 orders of magnitude greater than available human controls."

Khilyuk and Chilingar (University of Southern California) are the authors of the article published in Environmental Geology.

UPDATE: The only insight about CO2 that has really changed since 1990 is that some people became uncontrollably irrational.

Lubos has a sweeping historical, legal, and scientific look at CO2.
