Valiana Iznyuk 11/7/20 Climate change data analysis Post lab 11 E-1

1. The relationship between Atmosphere CO2 and CO2 Emissions is that as CO2 emissions increase, atmospheric CO2 also increases. 2. The relationship between temperature and Atmospheric CO2 is that as the atmospheric CO2 increases, the temperature also increases. I think that atmospheric CO2 drives the relationship because carbon dioxide influences the controlling temperature on earth. 3. Over time, the anomaly increases as the years go on. The approximate change in anomaly observed is 0.00040287873. 4. Based on the results, there is a relationship between CO2 emissions and change in climate. Every year as temperature increases, so does CO2 emissions. 5. During the preindustrial time, the anomaly was -0.2726. In 2017, the anomaly was 0,7243, With the added 0.4 degrees to 2017, the anomaly was 1.1243. The difference between 2017 and the pre industrial time period is 0.8517, which indicates that we haven’t gone over the 2 degrees change limit. It would take about 1.1483 degrees to reach the limit of 2 degrees.

6. I think that from this time moving forward, the temperature might keep increasing. Based on the data provided, we see that the average temperature from 2016 to 2017 decreased about 0.12 but from 2015 to 2016 there was an increase of 0.034 degrees. I think that every year the highest and lowest temperatures will fluctuate, but overall, the temperature will end up increasing as years go on. I think that the goals could be met based on how things are going but I also think that we might go over the 2 degrees limit. The Paris Agreement “encourages parties to formulate and communicate “long-term low greenhouse gas emissions development strategies”” ( c2es.org) which could help decrease the unnatural CO2 emissions being put into the atmosphere.

The results of the lab was the graphs we created. We started off by selecting atmospheric CO2 and CO2 emissions to create our first graph which was a column chart. From there, we went to the horizontal axis and changed the minimum to 275. We created our second graph by selecting the mean annual global temperature and atmospheric CO2 and created a scatter plot graph. For this graph, we went to the vertical axis and changed the minimum to 13. Lastly, we selected temperature anomaly and year to create a scatter plot graph as well. For this graph we didn’t have to change anything. We found that for atmospheric CO2 vs. CO2 emissions as CO2 emissions increased, the atmospheric CO2 increased as well. For the second graph (mean annual global temperature vs. atmospheric CO2), we found that as the

atmospheric CO2 increases, so does the annual temperature. For the third and final graph

( temperature anomaly vs. year), we found that the temperature anomaly

increases throughout the years.

The results were kind of what I had expected. I was surprised to see that the Atmospheric CO2 vs. CO2 emissions had more of an exponentially increased graph. It was interesting to see how CO2 emissions impact atmospheric CO2. I was also surprised to see that there were alot of ups and downs in the temperature anomaly vs. year graph. It was interesting to see how the temperature increased/decreased during the pre industrial times and then after 1975 there was a huge rise in temperature anomaly. I expected that as atmospheric CO2 was imputed/added into the atmosphere the temperature would increase, but it was still interesting to see how much atmospheric CO2 would cause the global temperature to increase.

The result of this experiment does support the goal of this lab because we got to get more familiar with using google sheets/excel to create graphs. We also got to get familiar with using the anomaly formula which we needed for the data calculations. We also got more familiar with carbon dioxide and greenhouse gases and how it impacts/influences the atmosphere.

The scientific concept/reason was to get more familiar with google sheets/excel and become comfortable with creating graphs. Another reason was to get familiar with using the anomaly formula and interpreting the information and relationships between them.

Some things that I learned from this lab is the greenhouse effect and how greenhouses gases trap heat that is given off by the earth. I also got more information about the Paris Agreement and what its purpose is....
