Global Warming Essay

1160 words - 5 pages

The topic of global warming is one of great discussion throughout the scientific community. The scientific evidence surrounding the global warming is astounding and undisputable such as the occurrence of heat-sealing carbon dioxide confirmed in the mid-19th century. With increased greenhouse gasses, the earth’s temperature is warming. The earth is also responding to solar outputs seen in ice cores sampled from Greenland, Antarctica. In addition, sea levels are rising rapidly compared to years prior. “Global sea level rose about 17 centimeters (6.7 inches) in the last century. The rate in the last decade, however, is nearly double that of the last century.” (Climate change: How do we know? n.d., para. 6) Not only are ocean levels rising, ocean temperatures are also warming, absorbing much of the escalation in heat. Temperatures have also been on the rise, since the 1970’s, earth has recorded the warmest 20 years on record, 10 of these years transpired in the last 12 years. The scientific evidence continues throughout our earth with regards to shrinking ice sheets, glacial retreats, declining Artic sea ice as well as ocean acidification. The acidity levels within the ocean has jumped by 30 percent, subsequently from humans producing higher levels of carbon dioxide.
There is a consensus within the scientific community, global warming is a reality. According to the National Aeronautics and Space Administration (n.d.) website, 97 percent of scientists agree, global warming indeed exists and are extremely likely cause by human undertakings. A statement released by 18 renowned scientific associations stated “Observations throughout the world make it clear that climate change is occurring, and rigorous scientific research demonstrates that the greenhouse gasses emitted by human activities are the primary driver.” (Consensus, n.d., para. 2)
Global warming is a very controversial topic in that many are simply non-believers. Global warming exists because of greenhouse gasses being produce via human activities, rising earth and ocean temperatures as well as sea levels are just the tipping point to how global warming is affecting our planet. Global warming has been a long standing scientific argument. As Minnesotans just experienced this past winter, winter can be very real and harsh at times. Following this recent winter, many people dispel the reality of global warming as just a myth simply because of what they have experienced, without looking at the real data, the facts behind the topic. Global warming is also a highly contested topic within our political landscape, dividing parties and raising or losing elections based on climate change. “The source of a climate change message is also very important – if the audience trusts the communicator, they are more likely to trust their arguments.” (Why are people still skeptical about climate change? n.d., para. 10) Some believe climate change can threaten our trade and industry sector,...
