The Potential Relationship Between Human Activity and Climate Change The idea of global warming has been around for over one hundred years, but in recent decades climate change has become a serious threat to national security. To better understand, global warming is defined as the gradual increase in the overall temperature of the earth's atmosphere, generally recognized as the greenhouse effect, and is caused by increased levels of carbon dioxide, CFCs, and other pollutants, also known as greenhouse gases. Researchers have debated for years about the main causes of global warming. Although history can show that global warming is inevitable, the majority of evidence points to human industry and agriculture as a primary cause for this…show more content…
This replaces the production of oxygen and clean air, with poisonous greenhouse gases.With all the toxic exposure of carbon dioxide polluting the air “multiple lines of scientific evidence show that Earth’s global average surface temperature has risen some 1.3°F since 1850” (Ecological 4). Industries in the world today are well aware of the effect their production companies have on the environment, but as long as profit is involved, there is no stopping them. Studies show that “if “business as usual” practices continue, climate change in coming decades will be exceptionally rapid, much more rapid on a sustained global basis than the transitions into and out of past ice ages” (Ecological 38).
There have always been cases of extreme weather conditions, but in recent years, these weather conditions are becoming more and more common. It was believed for years that climate change had nothing to do with weather conditions. Since then, because more people are paying attention to the issue of global warming, the Intergovernmental Panel on Climate Change (IPCC) has reported that “a changing climate leads to changes in the frequency, intensity, spatial extent, duration and timing of extreme weather and climate events, and can result in unprecedented extreme weather and climate events” (Field). Due to the rise in the Earth’s temperature over the past couple of years, the probability of severe heat waves and droughts has increased. As a result of
