Global warming is a natural occurrence that is not caused by humans, but humans have accelerated the process by changing the environment negatively worldwide. The term “global warming”, though, does not incorporate the whole definition. The “greenhouse effect” is the term that is used to accurately describe the situation. The greenhouse effect has two aspects to its meaning. It encompasses the natural greenhouse effect and the man-made “enhancement” of the natural greenhouse effect (Spencer). Both of these have an influence on what is happening with the climate. Climate change can come from one of three basic causes: man-made, natural external forces, and internal, natural variability (Begley).
Many of the human climate drivers have a big effect on the warming of the Earth. One of climate drivers that is getting the most “heat” for causing the warming is the burning of fossil fuels. Fossil fuel emissions are 30 times that of all other non-biological emissions (Mihm). Scientists argue back and forth about whether the emissions are actually affecting the rate at which the world is warming up. The Intergovernmental Panel on Climate Change (IPCC) says that there is a greater than 90 percent certainty that the emissions have caused most of the increase in the global average temperatures since the 20th century (Ekwurzel). Aerosols, on the other hand, have played a big factor on cooling down the Earth.
Aerosols are tiny particles that are mainly released through emissions of sulfur…
