World War III, Global Warming
“People tend to focus on the here and now. The problem is that, once global warming is something that most people can feel in the course of their daily lives, it will be too late to prevent much larger, potentially catastrophic changes,” Elizabeth Kolbert. For decades our world has been changing slowly, and we have felt the wrath of global warming. Recent hurricanes such as Ike, Wilma, Katrina, Rita, and now Sandy have caused many casualties, billions of dollars in damage and chaos to environments around the world. The effects of these storms are only getting greater with time. We can’t simply adapt to it, and the costs are incalculable. What we are facing is huge, global warming is real, and it is here! It’s time we start focusing on using clean energy exclusively, because the better option is out there. The basic physics of global warming are pretty straightforward. Carbon dioxide reflects energy in the infrared region, rather than letting it pass through, leading to greenhouse effect. The greenhouse effect heats the Earth because greenhouse gases absorb outgoing radiative energy and re-emit some of it back towards earth. This was first discovered by Svante Arrhenius back in 1896. Burning coal and oil releases carbon dioxide (CO2), these two resources are what we use most to live the way we do today. We have direct measurements of CO2 concentrations in the atmosphere going back more than fifty years, and these measurements confirm that concentrations are rising rapidly. Though natural amounts of CO2 have varied from 180 to 300 parts per million (ppm), today's CO2 levels are around 390 ppm, that's 30% more than the highest natural levels. Scientists have confirmed with this information that the unnatural levels of CO2 are indeed manmade (How we know human activity is causing warming). The greenhouse effect is what leads to the rare storms we have had over the past decades. Hurricanes are known to get their energy from warm...
