Milankovitch Cycles: The Cause Of Climate Change

Across the globe, people debate the cause of climate change. Some claim that all observed changes are simply natural, pointing to the historical records of the periodic rise and fall in global temperature. Others dispute those claims and instead state that climate changes are being caused by humans, and the unchecked release of carbon. Neither group is neither fully correct, nor incorrect. Climate change is both anthropogenic (human caused) and naturally caused. The difference between the two being: natural changes to the environment tend to be cyclical, balanced, and relatively ineffectual when compared to human changes to the environment, which are neither cyclical nor balanced. For the millennia that Earth has existed, many fluctuations in Earth’s climate have been observed. These changes tend to be cyclical, and in the long run the Earth remains in a constant state. Milankovitch cycles- fluctuation in the Earth’s orbit- are a key contributor to these temperature changes. As K. D. Bennet, an expert in climate cycles, states, “It has now been shown that Milankovitch cycles control the pace of Quaternary ice ages... with the 100- [kilo year] eccentricity cycle dominant in early Quaternary...” and that "Milankovitch cycles produce variations in the amount of solar radiation received by the earth and the latitudinal and …show more content…
However, natural influences- Milankovitch cycles and volcanic emissions, for example- are dwarfed by the anthropogenic release of carbon, which has caused an imbalance in the release and reabsorption of carbon dioxide and therefore a steady climb of carbon in the Earth’s atmosphere. It is clearly true that both humans and the planet itself alter the climate and cause it to fluctuate, however, human impact is much less stable and much more apparent than natural impact, which has historically displayed itself to be overall
