All Scientists are Sceptics ~Professor Bob Carter

Whenever someone asserts that a scientific question is “settled,” they tell me immediately that they don’t understand the first thing about science. Science is never settled. Dr David Deming

Perhaps the most frustrating aspect of the science of climate change is the lack of any real substance in attempts to justify the hypothesis ~Professor Stewart Franks

Roman Warming, Medieval Warming, 20th Century Warming, Is this a trend?

A Two-Thousand-Year Temperature History of the Extra-Tropical North...
Ljungqvist, F.C. 2010. A new reconstruction of temperature variability in the extra-tropical Northern Hemisphere during the last two millennia. Geografiska Annaler Series A 92: 339-351.


This new study of Ljungqvist is especially important in that it utilizes, in his words, "a larger number of proxy records than most previous reconstructions," and that it "substantiates an already established history of long-term temperature variability." All of these facts, taken together, clearly demonstrate that there is nothing unusual, nothing unnatural or nothing unprecedented about the planet's current level of warmth, seeing it was just as warm as, or even warmer than, it has been recently during both the Roman and Medieval Warm Periods, when the atmosphere's CO2 concentration was more than 100 ppm less than it is today. And this latter observation, together with the realization that earth's climate naturally transits back and forth between cooler and warmer conditions on a millennial timescale, demonstrates that there is absolutely no need to associate the planet's current level of warmth with its current higher atmospheric CO2 concentration, in clear contradiction of the worn-out climate-alarmist claim that the only way to explain earth's current warmth is to associate it with the greenhouse effect of CO2. That claim -- for which there is no supporting evidence, other than misplaced blind faith in climate models -- is totally bogus.

  1. What the study neglects to examine is the rate of change. The rate of change from 1680 to 1700 is apparently more rapid that the rate from 198- to today, a similiar time period. This would indicate that perhaps the rate of change today is not artifically raised by man caused CO2.
