Global temperatures, CO₂ concentrations and oceans

International Journal of Global Warming (IJGW), Vol. 30, No. 4, 2023

Abstract: During the past 170 years, temperatures and atmospheric CO₂ concentrations have increased. Published data on global temperature, CO₂ data, and data on sea ice in the Arctic have been investigated. It is seen that support for human activities causing the observed increases is weak. It is found that the rate of change in CO₂ concentration is controlled by global temperature rather than vice versa. To stop the growing concentration, the temperature has first to be decreased by about 1.4 K. This makes it questionable if attempts by humans to modify the global temperature, or the concentration of CO₂ in the atmosphere will give any noticeable result. A correlation is found between seasonal variations in CO₂ concentrations and Arctic sea ice quantities. The present increase in CO₂ concentration and temperature is similar to one 55 million years ago, indicating that the Earth passed a 'tipping point' around 1750.
