1) Referring to your responses to Problem 1. Energy Balance and Equilibrium, construct a trajectory of Earth's equilibrium temperature values (along vertical axis) vs. CO2 concentrations (horizontal axis) as they increase. Mark the critical temperatures and CO2 concentrations with the labels T+ and C+ respectively. Also use an arrow to indicate the direction of the trajectory.
2) Same as above, but for decreasing CO2 concentrations. Mark the critical temperatures and CO2 concentrations with the labels T- and C-, respectively. Also use an arrow to indicate the direction of the trajectory. (HINT: The + and - values should not be the same)
3) Translate your understanding of (a) and (b) into the context of the present
