I am currently enrolled in Geology 101 at the University of South Carolina and the textbook we are using, EARTH an Introduction to Physical Geology, teaches that humans are to blame for increasing temperatures. The book discusses that the climate indeed changes from time to time and warming periods are normal, but our present warming period is increasing a lot faster than the trends. They discuss that CO2 emissions is mainly to blame for high temperatures. Humans are said to be burning fossil fuels and emitted a large amount of CO2 in the air which is creating dangerous theories. The authors of this book are teaching that there are naturally occuring processes in which cause increasing temperatures but not enough to cause the increase we are having at this time. In the authors’ minds, humans are mostly to blame for the inccreasing temperatures.
