A new study suggests CO2 molecules have little consequential impact affecting outgoing radiation, and that climate models attribute global temperature effects to CO2 that are fundamentally erroneous.
Russian physicists (Smirnov and Zhilyaev, 2021) have published a peer-reviewed paper in the Advances in Fundamental Physics Special Issue for the journal Foundations.
They assesses the role of CO2 molecules in the standard atmosphere and assert “we have a contradiction with the results of climatological models in the analysis of the Earth’s greenhouse effect.”
Key points from the paper include the following:
1. Climate model calculations of CO2’s impact on global temperatures are in error by a factor of 5 as a result of “ignoring, in climatological models, the Kirchhoff law” which says radiators are “simultaneously the absorbers.”
2. Change in the concentration of an optically active atmospheric component (like CO2) “would not lead to change in the outgoing radiative flux.”
3. CO2 molecules “are not the main radiator of the atmosphere.” Water vapor molecules are, and thus they “may be responsible for the observed heating of the Earth.”

t’s so cold in the Arctic that:
Two icebreakers are on the way to rescue ice-locked ships on Northern Sea Route (snip)
District authorities in the Russian Far East have decided to commission two icebreakers to aid the vessels currently ice-locked in the East Siberian Sea. (snip)
The commissioning of the powerful icebreaking vessels comes as severe sea-ice conditions have taken shippers by surprise. There are now about 20 vessels that either are stuck or struggling to make it across the icy waters.
But what about the Antarctic ice cap?
That’s not about to melt either:
[T]he South Pole also just witnessed a historically cold winter. As reported last month: “Between the months of April and September, the South Pole averaged a temperature of -61.1C (-78F). Simply put, this was the region’s coldest 6-month spell ever recorded, and it comfortably usurped the previous coldest ‘coreless winter‘ on record: the -60.6C (-77F) from 1976 (solar minimum of weak cycle 20).”
In fact, it turns out that, according to a study released a week ago:
PALEOCLIMATE DATA INDICATE THERE WAS LESS ARCTIC SEA ICE DURING THE PRE-INDUSTRIAL PERIOD THAN IN MODERN TIMES, OR WHEN CO2 CONCENTRATIONS WERE 100 PPM LOWER THAN TODAY (280 VS. 380 PPM).
Scientists (Diamond et al., 2021) assert that during the 18th and 19th centuries Arctic sea ice extent minimum (September) values averaged 5.54 million km².

Die kalte Sonne reports on a new aerosol study by Liu et al.
The results are a major blow to the high greenhouse-gas climate sensitivity modelers.
IPCC scientists have a favorite wild card they often use to explain serious model discrepancies: aerosols. Mysterious cooling events in the past are often explained away by aerosols from major volcanic eruptions, for example. They act to filter out sunlight.
ccording to IPCC climate models, the mean global temperature should have risen by 1.5°C since 1850 due to the higher CO2 concentrations. But best estimates show that it has instead risen by only 1.1°C. So what about the missing 0.4°C?
Naturally, the missing 0.4°C of warming since 1850 gets explained by the higher 20th century aerosol levels in the atmosphere – due to the burning of fossil fuels. Air pollution by man over the course of the late 19th century and entire 20th century are said to have dimmed the earth, and thus this explains the 0.4°C less warming.
Surprise: global aerosol emissions have been flat over past 250 years
But now results by a new study appearing in the journal Science Advances by Liu et al tells us that the forcing by aerosols had to have been overestimated by climate modelers. IPCC modelers insisted that 20th century aerosol concentrations were higher than during the pre-industrial times, and this is what kept the climate from warming by 1.5°C.
According to the scientists led by Liu, however, atmospheric aerosols in the preindustrial times were just as high as they were just recently. They were in fact more or less constant over the past 250 years. No change means it could not have been aerosols putting the brakes on temperature rise:
That’s a real embarrassment for the IPCC modelers. It means CO2 climate sensitivity has been overestimated.
