Turn Part I into Dr. Doddridge electronically, or bring to class and give to Prof. Robock. Write the Chapman mechanism describing ozone in the natural unperturbed stratosphere as a series of reaction steps. Number these steps, as you will need them in 3.3. Please indicate on the figure where anthropogenic aerolsols would appear and how they could affect temperature. Please include both direct and indirect effects.
Cloud feedbacks are probably the part of the climate system that is the least well understood.
Mean temperature is not the only thing that changes when climate changes. Describe how the diurnal cycle of temperature has changed in the past 50 years around the world. Describe how precipitation has changed during the past 100 years. Describe the climate change of the past 500 years.
