Questions:
1. What happened to the amount of carbon dioxide in the atmosphere from 2010–2017? By looking at the graph, I can tell it went up by about 2 (ppm) per year. In 2010 it was 390 ppm and by 2017 it was up to 406 ppm.
2. How did the global temperature change from 2010–2016? By looking at the graph, I can tell it went up from 0.71 degrees (C) in 2010 to 0.99 (C) degrees in 2017
3. What is the relationship between the amount of carbon dioxide in the atmosphere and global temperature? The amount of CO2 in the atmosphere directly affects global temperature, because the CO2 gets trapped in the atmosphere.
4. How have humans contributed to the rise in global temperatures over the past century? Humans have contributed to the rise in global temperatures by burning fossil fuels. This happens when the process of burning coal or oil combines carbon with oxygen in the air to make CO2, which is a greenhouse gas that pollutes the air.
5. What natural processes have affected global temperatures? According to Nasa’s Earth Observatory, “two major volcanic eruptions, El Chichon in 1982 and Pinatubo in 1991, pumped sulfur dioxide gas high into the atmosphere. This is an example of natural processes affecting the global temperature. The gas was converted into tiny particles that lingered for more than a year, reflecting sunlight and shading Earth’s surface.”
This is just one way humans have affected global temperature.
