Early in the earth's history, the sun was dimmer and produced only about 70% of the energy it shines with today. this made for a solar constant s = 952 w/m2 (compared to the present-day value of 1360 w/m2). we refer to this as the faint young sun era. the following calculations follow the same method we used in class and is used in dessler to calculate the surface temperature of earth, but for the faint young sun era instead of the modern day. you can assume the albedo of the earth was the same then as it is now. first, we'll consider what the earth would have been like during the faint young sun era if it had no atmosphere. what was the energyin per area during the faint young sun era? round to the nearest w/m2. hint: you have an equation to calculate this simply.
