2 More Studies Affirm A Glaring Lack Of Correlation Between CO2 And Temperature

Reconstructions of past temperatures show much colder periods with higher CO2 levels or as-warm or warmer periods with much lower CO2 levels.

A new study (Paus, 2020) indicates modern July temperatures center around 7.5 to 8°C in the Scandes Mountains (Norway). Today’s CO2 atmospheric concentration has reached 410 ppm.

During the latter stages of the last ice age (19,000 to 17,000 years ago), Late Glacial (LG) CO2 fluttered near 200 ppm. But with the discovery of temperature-sensitive tree species in the area it can be affirmed that July temperatures were also “at least 7-8°C” in the Scandes at this time. Despite more than a doubling of CO2, there has been no consequent summer temperature increase in this remote location.

In another new study from Eastern Europe, Blagoveshchenskaya (2020) has determined January temperatures were almost 11°C warmer than the Little Ice Age (700 to 300 yrs ago) and 4°C warmer than today from about 6,000 to 4,500 years ago.

CO2 levels were 270 ppm when this region was 11°C warmer and 275 ppm when 11°C colder. It is 4°C colder today, at 410 ppm, than it was when CO2 was 270 ppm.

So, once again, reconstructions of Holocene temperatures do not support the narrative that CO2 and temperature changes are correlated.

    Late Glacial (LG) CO2 fluttered near 200 ppm.

    200 ppm CO2 is quite low.
    We can be glad this has doubled.

    About 1,000 years ago, when CO2 levels were much lower than they are today…

    “Roots of plants and deep Viking graves found in South Greenland in soil that is now tjaele (permafrost or permanently frozen ground) indicate that the annual mean temperature must have been 2-4°C warmer than now.”

    Alaska’s Mendenhall Glacier is melting and retreating, exposing the trunks of ancient trees. Carbon dating has revealed that some of the trees were growing 1,000 years ago, and some about 2,000 years ago. In other words, the Medieval Warm Period and the Roman Warm Period were both warmer than our Modern Warm Period, and were warm long enough for forests to flourish where the Little Ice Age created a giant glacier.

    Another non-correlation of temperature with CO2. Climate change is a fact, and natural.

    One of the key arguments put forward by supporters of AGW is that the sun is relatively stable and doesn’t affect climate to any noticeable degree. Unfortunately it is becoming increasingly evident that this is not the case. Over the last couple of years, during the current extended solar minimum – when the sun has been unusually quiet and stable – it has been possible to observe solar behaviour to a degree not readily possible previously giving rise to some interesting conclusions. The following might be found interesting:
