The Intergovernmental Panel on Climate Change (IPCC) deliberately limited climate science to focus on CO2 and temperature. The United Nations Framework Convention on Climate Change (UNFCCC) directed them only to consider human causes of climate change. They used this to narrow the focus of all variables that create the climate and thus eliminate major variables that cause climate change. A major example is the so-called greenhouse gases (GHG). Three of them account for almost 100% of the total; by volume, they are Water vapor (H2O) (95%), Carbon dioxide (CO2) (4%) and Methane (CH4) (0.36%). There are no accurate measures of any of these regarding the amount actually in the atmosphere or the changes in input and output from natural sources over any period.
