Climate Change can be caused by various happenings on our planet. When climate change occurs; temperatures rise at a drastic rate, and when they do many different changes to our planet can occur. It can result in more floods, droughts, intense storms, and even harsh wildfires. Oceans and glaciers have also fallen victim to climate change, with the oceans becoming warmer and the glaciers melting faster. As these changes happen, they will most likely present challenges for our society and environment in the future. These effects bring out the questions about whether or not such changes are man made, or if they are just natural causes. Therefore, this essay will be based on the argument that climate change is manmade and it is a real occurrence that cannot be ignored any longer. The first question many people ask when on the subject of climate change is, “what is it?” Climate change is defined as; a change in global or regional climate patterns, in particular a change apparent from the mid to late 20th century onwards and attributed largely to the increased levels of atmospheric carbon dioxide produced by the use of fossil fuels.** The next question that is always asked is, “How do we know?” Well, for example, the global temperatures have risen by at least 2.0 degrees fahrenheit since the late 19th century. This change was driven mainly by increased carbon dioxide emissions into the atmosphere. In the past 35 years, warming has begun to occur more often, and 16 of the 17 warmest years have occurred since 2001, 2016 being the warmest year on record. ** Another example of how we know that this is happening is the warming of the oceans, and the melting of Arctic ice. The warming of these waters is causing ice shelves to melt from the undersides, which means they are shrinking rapidly. A study was conducted and it found that basal melt accounted for 55 percent of all Antarctic ice shelf mass loss from 2003 to 2008, an amount much higher than previously thought. ** Global sea levels have risen about 8 inches in the last century and this could potentially pose danger upon the Arctic, it’s wildlife, and coastal cities like california. Other effects of the oceans warming is that it’s killing the coral reefs, which are home to hundreds upon thousands of living creatures and is considered one of the biggest ecosystems on Earth. What is happening is that the waters are becoming too acidic for the coral reefs to thrive, coral reefs are unable to fight against the acidity and are unable to absorb the calcium carbonate they need to survive. Thus, the coral reefs are becoming bleached and dying, which then affects the animals who relied on those coral reefs to survive, which in turn puts them in danger and, in the long run, effects us in the end. Many scientists agree that the main cause of climate change is the human expansion of the “greenhouse effect” while many others claim it is just a “natural change” or just a “change in the sun” that is making everything warmer. The “greenhouse effect” is warming that results when the atmosphere traps heat radiating from Earth toward space. ** There are five main gases that are contributing to this effect, they are; water vapor, carbon dioxide (the biggest one), methane, nitrous oxide, and chlorofluorocarbons. On Earth, human activities are changing the common greenhouse. In the course of the most recent century the consuming of non-renewable energy sources like coal and oil has expanded the convergence of atmospheric carbon dioxide (CO2). This happens on the grounds that the coal or oil burning procedure joins carbon with oxygen in the air to make CO2. To a lesser degree, the clearing of land for agriculture, industry, and other human activities has expanded groupings of greenhouse gasses. Since 1978, many different satellites have measured the sun’s energy output. This data shows that there has been very slight drop in solar irradiance in recent years, so the sun doesn’t really appear to be responsible for any of the warming trends we are seeing.
