Arctic sea ice plays a critical role in maintaining the earth’s water cycle, regulating the temperature of the planet, and providing habitat for a variety of wildlife species. Because of climate change and other human disturbances, this valuable resource has been declining at disturbing rates over the past few years. The hypothesis for this study is that Arctic sea ice has declined over the past over the past 50 years. For this study data was collected from Statista: the minimum arctic sea ice extent 2007- 2022 and the maximum arctic sea ice extent 1979-2022. Then a scatterplot was created for each data set and tested with a t-test of slope, specifically a linear regression. The results are that there was no significant decrease in the minimum amount of ice through 2007-2022. However, there was a significant decrease in the maximum amount of ice through 1979-2022. In summary the hypothesis was supported because the linear regression t-test for each graph show a significant change in the maximum amount of ice, over a longer period of time. Accordingly, this study has helped by showing how responsive and vulnerable the ice is to climate change effects.
