Over the last several decades, global climate change has been scientifically proven to be a result of human activity (“Carbon Dioxide Emissions”). Industrial processes, fossil fuel combustion, and changes in land use have altered the balance of greenhouse gases (GHG’s) in the Earth’s atmosphere. (City of New York et al. 2013) By increasing the concentration of carbon dioxide and other GHG’s in Earth’s atmosphere, our modern society is gradually warming the planet and altering its climate (“Carbon Dioxide Emissions”). Most recently, a March 2012 study found that climatic changes resulting from a warming planet have already increased the frequency of extreme weather events, “most notably heat waves and precipitation extremes” (“Carbon Dioxide Emissions”). As New York experienced not too long ago with Hurricane Sandy, the Earth’s climate and weather patterns have responded to such changes, with increases in the frequency and intensity of extreme weather events, loss of animal and plant species, impacts to human health, disruption of ecosystems, and other effects (City of New York et al. 2013) Such effects of human-induced climate change present potential threats to the infrastructure, economy, and health of not only New York City but the entire U.S.
Carbon dioxide (CO2) is the primary greenhouse gas emitted through human activities (“Carbon Dioxide Emissions”). In 2012, CO2 accounted for about 82% of all U.S. greenhouse gas emissions from human activities (“Carbon Dioxide…
