Global temperature change observed over the last hundred years or so is well within the natural variability of the last 8,000 years, according to a new paper by a former Intergovernmental Panel On Climate Change (IPCC) lead author.
Dr. Philip Lloyd, a South Africa-based physicist and climate researcher, examined ice core-based temperature data going back 8,000 years to gain perspective on the magnitude of global temperature changes over the 20th Century.
What Lloyd found was that the standard deviation of the temperature over the last 8,000 years was about 0.98 degrees Celsius– higher than the 0.85 degrees climate scientists say the world has warmed over the last century.
“This suggests that while some portion of the temperature change observed in the 20th century was probably caused by greenhouse gases, there is a strong likelihood that the major portion was due to natural variations,” Lloyd wrote in his study.
If Lloyd’s results hold, the IPCC may have to revise how much warming it attributes to mankind. Lloyd’s study hits at a larger debate within climate science: how much warming is attributable to mankind or nature.

Wow, how long did it take to crack open the light of truth?
“there is doubt that CO2 causes any of the temperature changes”
I read that ice cores show that changes in CO2 levels *follow* changes in temperatures, not the other way round.
It makes sense, since increased temperature makes CO2 less soluble in water similar to Warming up a beer or a soda makes the CO2 fizz out. Because warmer water holds less dissolved gas, including CO2. Stands to reason that melting ice and warming oceans release CO2.
Yes, CO2 is a lagging indicator of temperature.
Lagging - that means not causal...but caused by.
Jackasses in government will never get it right.
“Lagging - that means not causal...but caused by.”
It seems comprehensible.
“Jackasses in government will never get it right.”
But maybe I’m wrong about that.
You know, I’m starting to put more and more blame for this mess on the bureaucrats.
