The ten researchers report that “three intervals were identified by their diatom assemblages and correspond within dating uncertainties to the Medieval Warm Period, the Little Ice Age and the 20th century warming trend.” During the MWP, they further indicate that “the duration of the summer was longer while the spring and autumn were shorter than the 20th century.” And they unequivocally declare that “the period between ca. AD 1150 and 1200 was the warmest interval of the past 1000 years.”The conclusion?
For yet another part of the planet, late-20th-century warmth in NE China, even with the help of an extra 100 ppm of CO2, was less than that of the Medieval Warm Period.
This, say the scientists, makes it extremely difficult to believe that earth’s current level of warmth largely owes its existence to anthropogenic CO2 emissions, as the world’s climate alarmists continue to claim it does.
Attention, jack-booted politicians robbing us of our money, controlling our lives and pauperising us in pursuit of a theory of CO2 which never looked a slam dunk and looks increasingly unlikely month by month.
I reject your self-righteous green posturing at my expense. And I am not alone.
