Kyle Gransee Burke ENG2-7 3/5/19 With the exponential growth of the human population, consequences will drag along with its booming populace. One of those major effects include climate change, driven by the excessive carbon dioxide release through human activities such as respiration and burning. The long-term effects of climate change will forever tamper Earth’s oceans and ecosystems, as repercussions will follow through agriculture, seasons, and precipitation patterns. Although some may argue climate change is not caused by humans, the residue left by climate change will impact the planet for generations to come with vast gains of global sea levels, and the consecutive increase of droughts and heatwaves and their intensities. As a result of climate change, global sea levels will rise credited by the melting of ice caps and land ice. According to NASA, “sea level will rise 1-4 feet by 2100” and in the next several decades, “storm surges and high tides could combine with sea level rise and land subsidence to further increase flooding in many regions” (“How climate is changing”). The rise of global sea levels would threaten infrastructure in urban coastal settings, including locals and regional industries. In the United States, approximately 40 percent of the population lives in areas of coastal areas with high population densities, leaving millions dependent upon roads, power and sewage treatment plants, and other facilities vulnerable to the backlash of climate change if sea levels rise. In an organic setting, “rising sea level creates stress on coastal ecosystems that provide recreation, protection from storms, and habitat for fish and wildlife, including commercially valuable fisheries” (“Climate Change: Global Sea Level”). The loss of coastal ecosystems and aquatic habitats will disrupt food webs in environments. With less fish, fisheries will go out of business providing a shortage of jobs, and protection from storms granted by reefs will disappear. As credited by climate change, the melting of glacial masses proves climate change acts as an imminent concern which may seriously alter Earth with time granted. In addition to the global rise of sea levels, the increase of heatwave plus drought intensity and prevalence makes climate change a serious concern worldwide. Projections depict summer temperature to continue rising, with both heatwaves and droughts in the Southwest “to become more intense, and cold waves less intense everywhere” (“How climate is changing”). Culminating from an escalation of dry climate, days of extreme heat will occur more frequently as soil moisture drops. Human health will deplete, as the elderly and young children struggle against extreme heat; agriculture and livestock battle from high temperatures leading to heat stress and particular damage. Energy demands will skyrocket because of high demand for air conditioning to cool down from blazing hot weather. In terms of labor, heatwaves and drought have the same catastrophic effect as part of climate change. Extreme heat plays a dominant role in daily life of many people: “Millions of people living in the United States work primarily outdoors—construction workers, police officers, farm workers, military personnel, roofers, postal workers, landscapers, and others—and are at risk of heat stress when temperatures soar” (“Heat Waves and Climate Change: What the Science Tells Us About Extreme Heat Events”). As stated, millions of people stand at risk of the acute and chronic impacts of prolonged, intense heat exposure by cause of climate change. The gradually increasing severity and popularity of extreme heat credited by climate change raises massive concerns among human populations worldwide. Although some may claim the catastrophic effects of climate change appear not standing as human-induced, contradicting evidence suggesting human-caused climate change correlates with direct measurements of ice core measurements of carbon dioxide. The scientific evidence claims, “the current warming trend is of particular significance because most of it is extremely likely (greater than 95 percent probability) to be the result of human activity since the mid-20th century and proceeding at a rate that is unprecedented over decades to millennia” (“Climate change: How do we know?”). Just before human civilization, seven cycles of glacial advance and retreat has subsisted, displaying consistent carbon dioxide levels, before precipitously ending at the start of the modern era of the human era. With the evidence provided, previously recorded atmospheric carbon levels heavily contrast a natural explanation for extremely rich carbon dioxide level as seen today. Definitively, causes of human-induced climate change abide as prevalent and backed by legitimate scientific evidence denying any circumstance where it would occur as a natural cause. To conclude, the burdens of climate change make it an impending disaster to occur if not prevented in time. The rising of global sea levels and extreme heat consequences of heatwaves and droughts provide much to worry about for the rest of this century and the next. With millions of people of all ages at threat to the resentment of climate change, it gives everybody a reason to worry for its imminent consequences, gradually occurring right now.
