On the Benefits of CO2

   “CO2 has not been proven to ‘drive’ climate change except as conveyed by the models which remain erroneous and incomplete.” Here is what I would have written instead of that sentence — much more detailed to avoid misinterpretation — and they probably would have cancelled me faster than they cancelled you, anyway. … Manmade CO2 emissions are one of many manmade and natural causes of climate change. Because there are so many climate change variables, no one knows exactly what each variable has done in the past. Many people claim to know. But they are just speculating. There is evidence that manmade CO2 emissions are responsible for at least some of the 1975 to 2015 global warming. Exactly how much is impossible to know. But there has also been no global warming since 2014, per UAH satellite data. That shows the warming effect of the largest amount of CO2 emissions over any 8 year and 9 month period in history, can be offset by the cooling effect of other climate change variables. The computer games called climate models merely predict whatever they are programmed to predict by humans. But no human on this planet has ever demonstrated the ability to make correct long term climate predictions. Meaning the output of climate models are just a variety of guesses. not based on data. There are no data for the future climate — there is just data-free speculation. The predictions for rapid, dangerous global warming (aka CAGW) from the “models” must be data free, because CAGW has never before existed on this planet. There can not be data for something that has never happened. … Your sentence (above) was a weak sentence that could be misinterpreted. Remember that you are dealing with an anti-CO2 religion, and you discredited their favorite boogeyman, CO2. The rest of your article is great, so I immediately recommended it to readers of my Climate Science blog, as one of the four best articles, out of 20 climate and energy articles I will read and recommended today: https://honestclimatescience.blogspot.com/2023/04/the-best-climate-science-and-energy_11.html I have been an advocate of much higher CO2 levels since 1997, based on reading a total of about 300 CO2 enrichment — C3 plant growth studies. My initial goal is 750ppm to start — I know greenhouse owners typically CO2 enrich to 1000 to 1500ppm. Any global warming from extra CO2 will be harmless, mainly affecting colder nations, at night, in the winter, with the VERY important exception of Antarctica. Because of the permanent temperature inversion over most of Antarctica, CO2 causes global cooling over most of Antarctica, NOT global warming. That’s why Antarctica is just as cold now as it was in the 1970s. And that’s why relative sea level rise, as measured with NOAA tide gauges, has not accelerated since the 1970s Richard Greene Bingham Farms, Michigan https://honestclimatescience.blogspot.com/

     Thanks Richard. Good analysis that I could almost turn into a MasterResource blog….

   Richard I definitely appreciate your comments and suggestions. I have since reposted the essence of my original post but with careful review of the content and with directly supportive references. I leave it to the reader to make their own conclusions from the preponderance of information and references provided adding strength to the message without directly poking the boogeyman. Much harder to make a case of misinformation. Special thanks to you and Rob.

   As my LinkedIn account was suspended again my revised post link is unfortunately no longer accessible. As of May 18th 2023 just before LI halted access due to posting “misinformation”, the revised post had: 2138 positive responses 397 reposts >228,000 views 700+ comments REVISED POST Based on several publications referenced below it Interesting that increasing CO2 levels are proving quite beneficial to plant life. Multiple studies including those by NASA show the earth has accelerated greening over the last 30 years largely due to increased levels of carbon dioxide especially in arid regions. Moreover, studies show the fertilization effect has increased carbon fixation by photosynthesis by 30% since 1900. Other studies are showing that increased CO2 levels are improving drought tolerance of plants by modifying stomatal conductance thus reducing water intake requirements. Increased global photosynthesis and water use efficiency contributes to a growing terrestrial carbon sink and thus a significant negative feedback to mitigate a warming climate. Based on these studies increased CO2 levels are essentially greening the earth and helping to feed the hungry evidenced by greenhouse supplementation studies showing 1200 ppm is optimal for plant and food growth. It is also interesting to note that current levels of CO2 in the atmosphere are near the lowest levels experienced over earth history as illustrated by Berner et. al. (GEOCARB) where levels are shown to have been commonly 3x current levels and up to 10x-20x in the Paleozoic. I am intrigued that the earth never experienced runaway heating evidenced by Scotese’s paleoclimate analysis. Perhaps this is because CO2 secondary feedback heating is limited by the IR logarithmic forcing law (illustrated by Huang)? So my question is: Do we really understand the dynamics of earth’s climate systems well enough to infer that CO2 is the principal driver of climate?
