Global Warming, Atmospheric Carbon, and Anthropogenic Carbon Emissions

Abstract

The finding that human carbon emissions cause global warming is supported by a Granger causality time series analysis of the anomalies of global temperature, atmospheric carbon concentrations, and human carbon emissions from a base period of 1950 to 1980. Two conjectures are offered for improving the fit of time series models algebraically derived from estimated first differenced time series models.
