The IPCC’s climate doomsday scientists claim the modern global temperatures are “unprecedented” - the global warming science facts are irrefutably that past climate was warmer than our modern temperatures with a much lower atmospheric CO2 level

Read here. Another study, another nail in the “unprecedented” AGW coffin. New scientific research keeps refuting the claims of IPCC and chicken-little pundits. The empirical evidence is robustly overwhelming: global temperatures were warmer thousands of years ago despite low CO2 levels.
The two images above reflect the evidence of the warmer climates some six to ten thousand years ago. The image on the left reveals the history of the northern treeline in Finland and the image on the right the same for Siberia. The simple fact of a more northern treeline in both cases requires earlier periods to be considerably warmer than the current climate.
Now, a new study reveals that the northern treeline in Rocky Mountains was at a much higher altitude from six to nine thousand years ago, which confirms the extra warm climate was not just limited to the Finland/Siberia areas.
“…finds that the elevation of the treeline in the Rocky Mountains of Wyoming was higher than the present from approximately 9000 to 6000 years ago, indicating the climate was warmer during that period as compared to present temperatures. The paper adds to thousands of others indicating that the current warming period is not unprecedented; nor unusual compared to natural warming in the past.” [Scott Mensing, Thomas Minckley, Robert Musselman 2012: The Holocene]
