CapitalClimate: Low Temperature Records Set in Northeast
As a generally cool July continues across the Northeast, several daily low temperature records for July 14 were set or tied this morning in the region and as far south as West Virginia
Ancient global warming shows the limits of our knowledge - Ars Technica
A new analysis of a past period of climate change suggests that there might be feedbacks in the climate system that we aren't aware of yet.

If there's a gap between the scientific community and the public when it comes to climate change, the PETM is pretty illustrative. While portions of the public are still arguing over whether changes in atmospheric carbon dioxide are likely to do anything bad to us, the scientific community has concluded that, based on everything we know, the sudden change in carbon was a significant contributor to the rise in global temperatures and drop in oceanic pH that occurred during the PETM.
Climate Research News » Natural Climate Shifts: Swanson v Tsonis
Tsonis et al have published 3 interesting studies (2007, 2009, 2009) on how natural climate cycles could account for the climate/temperature shifts in the 20th and 21st centuries. The main authors Anastasios Tsonis and Kyle Swanson appear to have slightly conflicting opinions in media articles as to the significance of their work to the case for man-made global warming.
Study shakes foundation of climate theory! Reveals UN models 'fundamentally wrong' - Blames 'Unknown Processes' -- not CO2 for ancient global warming | Climate Depot
A new peer-reviewed study may shake the foundation upon which man-made global warming fears are based. The new study discovered "something fundamentally wrong with the way temperature and carbon are linked in climate models."

The study, which was published on July 14, 2009 in the peer-reviewed journal Nature Geoscience, found CO2 was not to blame for a major ancient global warming period and instead found “unknown processes accounted for much of warming in the ancient hot spell.” The press release for the study was headlined: "Global warming: Our best guess is likely wrong."

"In a nutshell, theoretical models cannot explain what we observe in the geological record," said oceanographer Gerald Dickens, a co-author of the study and professor of Earth science at Rice University. "There appears to be something fundamentally wrong with the way temperature and carbon are linked in climate models."
