Abstract
The dynamics of carbon dioxide in the atmosphere is analyzed and it is shown that the Pinatubo eruption in 1991 had a noticeable effect on these dynamics. The growth rate slowed down. Moreover, analyzing the year-on-year CO2 growth data, we can see an an-thropogenic footprint, possibly due to the burning of fossil fuels. On top of this anthropo-genic contribution is a natural contribution that is of similar magnitude, and that closely follows the ocean surface temperature (influenced by ENSO, El Niño Southern Oscilla-tion). This latter fact is consistent with the hypothesis of the correlation of global temper-atures and carbon-dioxide in the atmosphere being governed by Henry’s Law, in which carbon dioxide variations are the result of, rather than the cause of, temperature changes. This latter being the so-called “greenhouse effect”, sometimes mentioned as responsible for (anthropogenic) climate changes, and that cannot explain the observed phenomena described here. Similar conclusions are drawn on monthly data of carbon dioxide and temperature as well.
Highlights
The United Nations Climate Change Conferences, Conference of Parties (COP), are yearly conferences held in the framework of the United Nations Framework Convention on Climate Change (UNFCCC)
If the greenhouse effect (GHE) hypothesis were correct, in that CO2 causes global temperature change, we do not expect this effect to be immediately visible in the oceans, which’d take a long time to heat up
The year-on-year increase of CO2 in the atmosphere shows a clear contribution of anthropogenic origin
Summary
The United Nations Climate Change Conferences, Conference of Parties (COP), are yearly conferences held in the framework of the United Nations Framework Convention on Climate Change (UNFCCC). We conclude that there is no human activity responsible for the Event or the slowing down of carbon dioxide growth (increase of the exponential-increase time constant) in the atmosphere.
