Preview - Climate Change In The Great Lakes 2019

Lake Temperature and Lake Levels

 

In the 2019 Climate Trends report from GLISA, there is additional focus on lake water temperature and lake water levels. The following graphs show changes from 1950-2019 in the 5 lakes (Michigan and Huron are grouped together).

Questions

Please answer the questions below.

What does the data indicate is happening to lake water temperature over time? Provide specific evidence from the graphs. 

If you were going to compare lake water temperature to another set of graphs, which one would you choose? Do you think it might be connected? Why?

Lake water levels are another incredibly important factor. What do the graphs indicate is currently happening to lake levels? Is there a trend over time?

If you were going to compare lake water levels to another set of graphs, which one would you choose? Do you think it might be connected? Why?

Ice cover (when the lakes freeze over) is another indicator that is being used when looking at the Great Lakes system. Based on the data you've seen, predict what is happening with ice cover in the Great Lakes (increasing, decreasing or staying the same) and explain your reasoning for your prediction.
