I have always believed Climate Change was mostly natural, here is a more scientific presentation showing 75% Natural forces are the cause of Climate Change. Thank you Ron Clutz for your analysis..
A previous post reprinted later below raised the question Who to Blame for Rising CO? It provided synopses of three studies challenging the IPCC orthodox explanation that humans are the cause by burning fossil fuels. This post brings the research up to date with a 2021 publication by Edwin Berry.
The graph above summarizes Dr. Berry’s findings. The lines represent CO2 added into the atmosphere since the 1750 level of 280 ppm. Based on IPCC data regarding CO2 natural sources and sinks, the black dots show the CO2 data. The small blue dots show the sum of all human CO2 emissions since they became measurable, irrespective of transfers of that CO2 from the atmosphere to land or to ocean.
Notice the CO2 data is greater than the sum of all human CO2 until 1960. That means nature caused the CO2 level to increase prior to 1960, with no reason to…

Dick, thanks for reblogging my post. Your post on energy ignorance and COP-26 inspired me to post your comments along with some relevant infographics.

Dr. Berry is about 175 – 25 = 150% wrong.
Mankind is responsible for about 175% of the rise in CO2 levels since precise measurements began (in 1958). “175%” is not a typo. Since 1958, mankind has added about 175 ppmv of CO2 to the atmosphere. We know this because the bean-counters keep track of fossil fuel and cement production, and we know how much CO2 is produced from that.
However, as you can see, the average outdoor CO2 level has risen only about 100 ppmv in that time:

That means Nature has removed 75 ppmv of CO2 from the atmosphere, as mankind was adding 175 ppmv. The difference is the 100 ppmv increase in atmospheric CO2 concentration since 1958:
Dr. Berry’s claim is that Nature increased the amount of CO2 in the atmosphere 75 ppmv, by removing a net total of 75 ppmv of CO2 from the atmosphere. If that sounds absurd that’s because it is absurd.

What’s more, nobody is to “blame” for rising CO2 levels, because the word “blame” implies harmfulness. The scientific evidence is compelling that manmade climate change is modest & benign, and CO2 emissions are beneficial, not harmful. The major harms from CO2 are all hypothetical, and mostly implausible. The major benefits are proven, measured, and very large.
