Global warming and long-term climatic changes: a progress report

Original Article


The authors believe that recent global warming of Earth’s atmosphere is not due to an increase in anthropogenic carbon dioxide emission but rather to long-term global factors. The human contribution to the CO2 content in the atmosphere and the increase in temperature is negligible in comparison with other sources of carbon dioxide emission. Discussed in this paper are sources, avenues of migration, and the amounts of naturally produced carbon dioxide and methane (greenhouse gases) and long-term changes in the Earth’s climate, which are necessary for understanding the causes of current temperature trends.
