One of the basic ingredients in the Anthropogenic Global Warming scenario (AGW) is the idea that burning fossil fuels will inject huge quantities of carbon dioxide (CO2 ) into the atmosphere that then will cause a heating up of the planet through the so-called greenhouse effect (GHE). This reasoning thus has two steps: 1) Human-originated CO2 increases the CO2 concentration in the atmosphere, and 2) An increase in CO2 will heat up the planet.

In earlier work it has been shown that in historic data CO2 changes in the atmosphere lags behind the temperature changes, making the latter the source rather than the result of CO2 changes. This already casts serious doubts on the AGW hypothesis.

In the current work the authors question if the changes in the CO2 concentration in the atmosphere are really due to human activity. They do this by using a specific-impulse analysis: by looking at the singular event of the eruption of Pinatubo in 1991 and the effect on the atmosphere they can determine the relative contributions of nature and humans. The eruption caused a temporary drop in temperature of the planet that resulted in a reduction of CO2 uptake in the atmosphere that was much larger than human CO2 production. This hints at that the human contribution to CO2 changes in the atmosphere are rather irrelevant compared to natural effects.

This is an important contribution to the scientific community, helping to demystify the climate change subject.
