Comparing Climates through Geologic Time

Compare the climate of the past Ordovician–Silurian time period with the climate of today. Choose your assigned geologic time period for comparison. Your post should answer two main questions: 1) How does the climate of your time period compare with the climate of today? Hotter? Colder? Sea level? Oxygen level? Provide a short overview of how climate is different and/or how climate changed over your chosen time period (if it did). You are welcome to use secondary sources to provide this overview. 2) How do scientists know about the climate of your time period? You should focus on one primary research article and explain how scientists are able to figure out what the climate of the past was like. What did they measure to understand some aspect of the climate of the past? ***Be sure to include a minimum of 3 sources and at least one primary source.***
