Pre-industrial CO2 levels were about the same as today

- How and why we are told otherwise

By Dr. Tim Ball, from the Canada Free Press, December 10, 2023 [here]

How many failed predictions, discredited assumptions and evidence of incorrect data are required before an idea loses credibility? CO2 is not causing warming or climate change. It is not a toxic substance or a pollutant. Despite this President Elect Obama met with Al Gore on December 9 no doubt to plan a climate change strategy based on these problems. They make any plan to reduce CO2 completely unnecessary.

Proponents of human induced warming and climate change told us that an increase in CO2 precedes and causes temperature increases. They were wrong. They told us the late 20th century was the warmest on record. They were wrong. They told us, using the infamous “hockey stick” graph, the Medieval Warm Period (MWP) did not exist. They were wrong. They told us global temperatures would increase through 2008 as CO2 increased. They were wrong. They told us Arctic ice would continue to decrease in area through 2008. They were wrong. They told us October 2008 was the second warmest on record. They were wrong. They told us 1998 was the warmest year on record in the US. They were wrong it was 1934. They told us current atmospheric levels of CO2 are the highest on record. They are wrong. They told us pre-industrial atmospheric levels of CO2 were approximately 100 parts per million (ppm) lower than the present 385 ppm. They are wrong. This last is critical because the claim is basic to the argument that humans are causing warming and climate change by increasing the levels of atmospheric CO2 and have throughout the Industrial era. In fact, pre-industrial CO2 levels were about the same as today, but how did they conclude they were lower?

In a paper submitted to the Hearing before the US Senate Committee on Commerce, Science, and Transportation, Professor Zbigniew Jaworowski explains,

The basis of most of the IPCC conclusions on anthropogenic causes and on projections of climatic change is the assumption of low level of CO2 in the pre-industrial atmosphere. This assumption, based on glaciological studies, is false.

Ice cores provide the historic record and data collected at Mauna Loa the recent record. Both records are drastically modified to produce a smooth continuous curve with little variability. This was necessary to confirm the evidence falsely concluded from many 19th century measures that pre-industrial levels were approximately 280 ppm and didn’t vary much. So how did they engineer the smooth curves and ignore the fact the 19th century record shows a global average of 335 ppm and considerable variability from year to year.
