Author: Eric T. Karlstrom, PhD
Article Abstract:
The author with the department of Geography at Cal State asserts that”… climate probably exerts a more profound influence on human history and nonhuman ecosystems than any other single environmental factor.” Scientists warn us that various gases, CO2, CFC’s, and others have begun to increase the atmosphere’s natural greenhouse effect, causing a global warming. Yet, Karlstrom suggests that human activity alone may not be the cause of “environmental woes”; rather, “… all twentieth-century climate variability could be the result of natural climate fluctuations.” (For an opposing view specifically relating to CO2, see J. Hannan, The Carbon Dioxide Problem and You)
