ABSTRACT

Environmental change is a big deal and not just for our society; it has affected every culture in human history. Change is constant and can be viewed on many scales, from daily weather to cycles lasting hundreds of thousands of years. Natural environmental change happens for many reasons, including the Earth’s rotation (e.g., day vs. night), seasonal trade winds, sea temperature fluctuations (e.g., El Niño Southern Oscillation every 5 to 7 years), air pressure movement (e.g., North Atlantic Oscillation), solar activity variation (e.g., Solar Magnetic Activity Cycle every 11 years), Earth’s orbital cycles (1000s to 100,000s of years), and tectonic cycles (100,000s of years).1
