Humans Cause Climate Change Essay

Are Humans the Main Cause of Climate Change? Climate change is a concerning problem to many people in the world today. There is a consensus among most scientists and ordinary people that climate change is occurring, but what is most debated is whether or not human activity is the main cause of these recent changes in temperature. The climate change which concerns peoples the most is the warming, but the cooling of the Earth is also a concern. There are many reasons that can contribute to the argument against man-made climate change which can be reasoned from science and logic. The main cause of climate change is not human influence due to the pressing evidence of earth cycles, sunlight sensitivity, and various other natural occurrences. …show more content…
Robert B. Laughlin, a physics professor at Stanford University, and Nobel Prize recipient for physics, believes, along with many others, that humans are not the main cause of global climate change. People are extremely insignificant when it comes to the impact on the Earth. “The Earth has suffered mass volcanic explosions, floods, meteor impacts, mountain formation, and all manner of other abuses greater than anything people could inflict, and it’s still here. It’s a survivor,” says Laughlin (Laughlin). This idea is based on the fact that the Earth has been flourishing through countless crashing meteors, the colliding of continents, and volcanic explosions that have wiped out entire civilizations. The Earth would not notice or care if someone is driving a hybrid car, or if a power plant is shut down. Therefore, significant global climate change cannot be attributed to the actions of humans. Laughlin also states, “far from being responsible for damaging the Earth’s climate, civilization might not be able to forestall any of these terrible changes once the Earth has decided to make them. Were the Earth determined to freeze Canada again, for example, it’s difficult to imagine doing anything except selling your real estate in Canada” (Laughlin). This reinforces the idea that humans are not in control and are at the mercy of the …show more content…
First, the natural temperature cycles of earth play a large role in the climate, proof of this is evidence of the ice ages and hot periods where trees thrived up by the North Pole, long before humans had any presence. Next, the Earth is extremely sensitive to sunlight, and its distribution can have make some areas warmer than others which explains the shrinking of the ice caps in the North Pole and the expansion of the ice caps in the South Pole. Then, the North Atlantic Oscillation in its negative index almost perfectly describes the weather that the Northern Hemisphere has been experiencing. In addition, volcanic activity releases SO2 which changes Earth’s temperature without any human involvement. Finally, through logical reasoning, humans, on the geologic scale, have little to no impact on the Earth. While humans are responsible for some aspects of climate change, their impact is dwarfed by the impact of natural processes and cycles of the
