When the establishment can't, or refuses, to understand the difference between plant food and pollution ordinary folk have a big problem. Moreover, the "problem" is a political tool used to control people. Carbon dioxide is not a pollutant, it is essential to life. Below 140 ppm, and life on our unique planet would collapse. The issue has been the promotion that certain molecules of CO2 emitted by modern industrial society can wreak havoc upon the Earth's weather and climate. However, there is no evidence that variations in atmospheric concentrations cause climate change. The Vostok ice core records some 400,000 years of real climate change, and the observation is that there is little correlation and no causation. If anything, the record shows that warming leads CO2.

The next is the word definition is the chemistry of photosynthesis that turns a condemned pollutant into life.
Clearly the more carbon dioxide going in, the more food and oxygen coming out. And it has been so since the first micro-critters appeared a few billion years ago. Hot rocks gave us CO2 and photosynthesis gave us oxygen and life. The identification of photosynthesis is, itself, interesting.
Van Helmot, in the 1630s was a dedicated observer and grew a willow tree under closed conditions. After five years he found that the tree had gained 164 pounds, but the box of soil had only lost 2 pounds. He argued that the increase had been due to water. Then, one could not imagine substance coming from air. But those limbs and roots, trunk and bark came from somewhere.
It was in the 1750s when Joseph Black first identified carbon dioxide. Calling it "fixed air", he observed how it could turn into calcium carbonate. Unknown until much later, this has been the process whereby carbon dioxide has been sequestered into literally mountains of CO2-based rock.

The swings from the warming El Ninos to the cooling La Ninas have been on forever, but the latest of the latter continues in its cool phase:

Also, the Southern Hemisphere suffered an unusually cool winter. On October 13th, Electroverse provided the following headlines:
"Cold Paraguay; Record Lows At Parkersburg; + ‘One-In-50-Year' Frost Decimates NZ Blueberry Crop; Antarctica Plunges below -80 C, Breaking Record".
It is ironical that without CO2, even at today's geologically low concentrations, climate promoters would not be alive. Like you and me, they inhale it at 0.04% and exhale it at 4%, without apology.
The promotion is both political and scientific pollution.
