[|Figure-1-Schematic-diagram-illustrating-role-of-atmospheric-aerosols-in-the-atmosphere.ppm] Scientists have discovered a relationship between natural particles in our atmosphere and climate change. The research shows that the cooling effect of atmospheric particles is greater during warmer months and therefore could slightly reduce the amount at which temperatures rise due to global climate changes. Computer models were used to map the effects of two naturally occurring particle sources: gases emitted from trees and smoke from forest fires. Plants release gases that go into the air and form the tiny particles. These particles alter the climate by either reflecting or absorbing rays from the Sun. This topic relates to environmental science due to the fact that climate change is a major problem in today's world. Since temperatures are rising at exponential rates, an important discovery like this could help fight against global warming. While there are heat-trapping chemicals that humans add to the atmosphere that lead to global warming (Miller 472), the discovery of these natural occurring particles could help dilute those harmful effects. The cooling effect from the particles can be described as a negative feedback loop. One change leads to a lessening of another change (Miller 51). The particles from the forest act as air conditioners that are reducing global warming from greenhouse gas emissions. I think it is interesting and essential that a discovery of this magnitude has happened. This is because global temperatures are currently rising at exponential rates and anything that can help reduce that rate is beneficial. Also it is interesting that these particles are able to be dominant in the warmer years. However it is unfortunate that the positive feedbacks in our climate are too strong for these negative feedback cooling effect. This means that cutting down on green house gases is still required to reduce the deadly effects of global warming. This article somewhat relates to the Clean Air Act of 1963. This law sets standards for limiting emissions or effluents for various classes of pollutants based on current technology. While the atmospheric particles are not directly reducing the amount of pollutants in the air, they are helping to reduce the effects that those pollutants have on our atmosphere.
