A new study based on 1,000 years of temperature records suggests global warming is not progressing as fast as it would under the most severe emissions scenarios outlined by the Intergovernmental Panel on Climate Change (IPCC).
"Based on our analysis, a middle-of-the-road warming scenario is more likely, at least for now," said Patrick T. Brown, a doctoral student in climatology at Duke University's Nicholas School of the Environment. "But this could change."

What exactly is the correct global temperature of the earth?
Apparently, “moderate” is Progressive Newspeak for “not at all.”
Do I believe that there is ‘climate change’ - OF COURSE I DO! It is just what those who want massive government intervention want to do about it that I find FRIGHTENING!
My thoughts as well. After all, ZERO is pretty moderate.
This guy’s going to get his a** kicked by other members of the scientific establishment.
Just like that other Climateologist a year or so back who was figuratively tarred, feathered and run out of academia on a rail for pointing out that the computer models were off by 50%.
LOL, what empirical data?
They have nothing that hasn’t been massaged, altered, or “averaged” in some fashion that destroys any value the original data may have had.
Also, you can’t get an accurate reading on top of blacktop...
-32F.
I know that something (somebody) is suggesting it. So much for Duke University’s credibility.
Perhaps another ice age would be preferable.
Patrick T. Brown, PhD student, deserves a medal for valor in the face of overwhelming enemy forces.
Such heterodox views can be expected from the occasional emeritus professor, and sometimes from a fully-tenured professor. However, a PhD candidate has to tread lightly — he has no protection whatsoever. If he used some weasel words, it’s no wonder (I’m not sure that “moderate” is even a weasel word — it might actually be the most descriptive word).
The thermometer was invented in the 1700’s, according the Wikipedia. The idea of Duke researchers basing their study on “1,000 years of temperature records” is unsupportable. Further, civilization on any level capable of keeping temperature records did not exist in most parts of the world 1,000 years ago, and not until the last few hundred years in many places...including much of the USA.
“A new study based on 1,000 years of temperature records”
Funny the thermometer wasnt invented until 1592 and it certainly wasnt accurate.
Well, we now know Patrick T. Brown will never get a government grant to study climate, so he better look for another line of work.
1592, Galileo
The "Medieval Warm Period" (950-1250 AD), also known as the "Medieval Optimum" was one of the best times for agriculture in history. The name "Optimum" was obviously not chosen because global warming caused the worldwide disasters that big government alarmists are predicting. We are unlikely to reach those optimum temperatures in the next two centuries under realistic climate models. Polar bears and other allegedly delicate species did not go extinct in that time frame.
The "Little Ice Age" (1350-1850 AD) was a far more difficult time for agriculture. While evidence clearly shows that temperatures warmed as the earth left the Little Ice Age, the modern response to that observation should be "duh!" and not "oh noes!"
Based on 1000 years of temperature records? Do they really believe that there are 1000 year old records with accurate temperatures for Siberia and Argentina?
You can get moderately accurate temperature data from (1) tree rings, (2) ice cores, (3) local pollen, and (4) written descriptions of weather events. Cross-referencing these sources produces a statistically reliable estimate, so long as the statistics are done honestly. We know there was far less snow and ice during the Medieval Optimum than there is today. We know the Thames froze annually throughout the Little Ice Age. Both observations are well supported by the reconstructed temperatures from the various proxies for temperature.
There are other methods of ESTIMATING pre-thermometer temperatures that give repeatable values. Dendroclimatology uses tree ring widths to get seasonal growing values by locations and ice field banding gives data on snow-fall and winter temps over long time frames.
Obviously not our current standards but it is what can be roughly quantified and thus show trends at the very least.
