The linked video was first released in 2012 when carbon dioxide was approximately 395 parts per million (PPM). The current value of CO2 is 417 PPM. Despite the minuscule elevation, the values in the linked video differ little. What the video does is illustrate better than words or numbers the insignificance of human-generated carbon dioxide - the progressive belief in the causation of global warming. This video gives a greater understanding of the improbability of climate change through the CO2 greenhouse effect.
While carbon dioxide is absolutely essential for life on earth, it is a mere trace element in the atmosphere, while the human contribution of CO2 is quite meager. The compound makeup of the CO2 molecule is exactly the same whether generated naturally or by any human activity. Also to remember is that historically, carbon dioxide has been measured in ice cores as high as 7,000 PPM.
