1.The debate as to whether the occurrence of global warming, or the increase in the earth’s average atmospheric temperature that causes corresponding changes in climate and that may result from the greenhouse effect (Dictionary.com, 2018) is real or simply a matter of opinion has been going for decades. Upon researching, one can conclude that the evidence and documentation of the changes in global climate in conjunction with the impact observed on humans, nature, and the geography of the planet are inarguably supported by scientific evidence. Some of the documented facts around the progress and impact of global warming include, a steady rise in sea level over the last century, rising average temperatures, and increases in the frequency and severity of weather systems. Additionally, the phenomenon is witnessed and documented across the globe. Scientific data and record keeping proves that the average temperature has increased by 1.3F to 1.9F since recordkeeping began in 1895; most of this increase has occurred since about 1970 and that mid-Atlantic seal levels have risen nearly 8 inches over the course of the last century. Scientific data indicates a According to NASA, there is no question that increased levels of greenhouse gases must cause the Earth to warm in response, arguing that factual data indicates that real, global change is occurring. For most, the vast amount of factual, documented data surrounding the existence and impact of global warming far outweigh any subjective opinions formed over time.

2.Climate change is science based and the entire earth population is responsible for that. For example, we burn fossil fuel, drive cars that emit carbon monoxide and create chemicals in order to make items that we use on an every day basis. Because of this, we create more issues that add on to the greenhouse effect and cause climate change. Polar ice caps start to melt, raising the sea level and temperatures in the atmosphere change, creating storms and surges. Human activities are essentially responsible for climate change. “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?, 2018). Furthermore, climate change didn’t just happen in a short period of time. It took years to be able to study the changes in the climate and notice the effects that it took. Several combined gases have had the opportunity to build up in our atmosphere, creating higher temperatures and the evidence can be shown in the earth’s natural patterns. ” Ice cores drawn from Greenland, Antarctica, and tropical mountain glaciers show that the Earths climate responds to changes in greenhouse gas levels. Ancient evidence can also be found in tree rings, ocean sediments, coral reefs, and layers of sedimentary rocks. This ancient, or paleoclimate, evidence reveals that current warming is occurring roughly ten times faster than the average rate of ice-age-recovery warming.” (Climate change: How do we know?, 2018). Evidence has been collected over the years, time and time again. In order to make a change to slow the effects of climate change, there needs to be a change in the human behavior. We need to be able to change the way we think when we use fuel, or when we drive our cars. We need to understand that climate change is real, based off several cases of evidence. We need to be understand that the climate change also changes our health as well. If we do not take the correct course of action, our society will greatly suffer the consequences.

3.One current public health controversy is climate change. Is it science based or myth? Justify your opinion with evidence from the literature?
Planet Earth has been though extreme weather changes and cataclysmic events for millions of years. Factors involving climate change would be events like the tilting of the Earths axis creating drastic shifts in climate, according to Encyclopedia Britannica (2018). Events like these would alter the global weather patterns making temperatures rise or plummet erratically. According to NOAA (2017) as climate change takes an increase effect around the world, sea levels will eventually rise and glaciers will begin to melt. The rising of the sea levels will decrease the coastal land masses therefore making it impossible for the worlds population to live. According to Encyclopedia Britannica (2017) over-population will bring problems like lack of resources, food, medicine to heal or treat the sick, and lack of fresh water. Pestilences and illness will appear everywhere and with the lack of sanitary conditions the increase of viruses and bacteria will become more common. The lack of sanitation and cleanliness are perfect areas for harboring infectious diseases that use different vectors (modes) of transmission. According to Encyclopedia Britannica (2017) Medieval Europe fell to a terrible epidemic. They called it The Black Plague. This was due uncleanliness and the unsanitary conditions, but the major problem were the rats that roamed through the cities. These rats contained insects that transmitted diseases. These rats would get into the populations food and water supply thus infecting and killing millions of people.
