SourceWhen 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.
