Abstract

The following adiabatic model is used to relate the global temperature to the atmospheric pressure. The temperature distribution in Earth’s troposphere at pressure more than 0.2 atm under greenhouse effect theory can be determined using the following equation: http://earthscience.conferenceseries.com/upload-images/earthscience2016-96452.png Where S is the solar constant; is the Stefan-Boltzmann constant; A is the planet’s reflectivity; b is a scaling factor; is the adiabatic exponent; and is the precession angle of the revolving planet. The proposed model considers the global temperature changes due to variations in mass and chemical composition of the atmosphere. Based on our model, releasing of anthropogenic CO2 and methane into the atmosphere does not have any appreciable effect on the average parameters of the Earth’s heat regime. Furthermore, they have no essential effect on the Earth’s climate. By considering different factors in the model, authors believe that all petroleum production and other anthropogenic activities resulting in accumulation of additional amounts of methane and CO2 in the atmosphere does not increase the Earth’s temperature but instead decreases the temperature. The authors also have shown that in many cases, peaks in the sun irradiation precede peaks in the CO2 concentration in the atmosphere. The authors predict slow temperature decline by 2016-2020, with stronger cooling by around 2040. The earth is about 20 years away from “little ice age”.
