Hey Mr. Wood it's Frankie from per. 3. I'm going to answer the questions from the May 14th journal. I think that the amount of CO2 is 386 million to 388 million. For the second question, I think that the time of day is about 1:30 in the morning. Also, I think as the time rises the CO2 will rise because from the May 12th journal it shows that on May 1st the CO2 level rised. Also, as the time rise the day usually gets hotter from all the plants,animals, and humans causing it.
