What is the trend in ice cover for Cazenoiva Lake over the last century?

1) What is the trend in ice cover for Cazenoiva Lake over the last century?

2) Given what you learned about the physical and biological properties of water speculate: what other factors might cause the trends in ice cover data to change over the past century? (you may want to review the physical characteristics of water and terrestrial plants).

3) Which proxy do you think would be more accurate to determine global climate change? The ice cover data or the data on blooming times collected by the scientists mentioned in the NPR study we listened to in this module? Why do you think this? Give reasons based on your research into what causes ice to melt on lakes, and what may impact blooming times from the discussions. Cite your sources for full credit.
