Question
Identify scientific evidence that supports or refutes climate change.
Discuss whether you support or do not support climate change as a human-caused event.
Identify possible causes of climate change that are human related.
Identify possible cause(s) of climate change that is/are not related to human activity.
Identify the potential results of climate change.
Suggest possible ways that humans could reduce the threat of climate change. (You must include this even if you do not agree that climate change is human driven.) Write a persuasive article that you could post on a blog site or submit for an editorial section of a paper or website. You will want to include information on the three factors listed above. Use what you have learned to convince the audience that climate change is real and must be taken seriously.

Explanation / Answer
Scientific evidence of Climate change: NASA shows the graph of Carbon dioxide levels from past to 1950 where the levels increases 300 parts per million. High Carbon dioxide levels heats the earth and climate changes to due to the change in temperature. Reference: https://climate.nasa.gov/evidence/ Scientific evidence that oppose Climate change: In contrast, some scientists are arguing that the rise in temperature cannot be attributed because of the shrinking of glaciers or rise in ocean levels. Reference: https://www.newscientist.com/letter/mg18624950-100-glaciers-are-cool/ Climate change is a human caused event: Climate change is a human caused event once industrialization started. Lot of factories were established and fossil fuels were used when trains came up. Causes of climate change that are human related: Use of non-renewable energy resources like coal, methane, hydrocarbon, crude oil etc. to generate energy but these resources generate enormous heat and carbon dioxide to the atmosphere. Deforestation led to climate change because trees act as a natural carbon sink to absorb carbon dioxide. Over utilization of materials by humans led to over production and release of heat. Causes of climate change that are not human related: Increase in the level of solar radiation. Release of methane gas to the atmosphere by cattle (13 % of the world’s available methane) Volcanoes release high amount of carbon dioxide during eruptions. Plate movement causes changes in air circulation and in turn changes in climate.
