- list human produced greenhouse gases and rank them in terms of
relative
importance and global warming potential (GWP)
- explain GWP and why it varies so much from one gas to another
- explain why we don't worry about human emissions of water vapor
- discuss the role of aerosols in the greenhouse warming problem, the
distinction
between sulfur and soot; direct vs. indirect effects
- mention large incertainties regarding cloud feedbacks
- explain how models are used to estimate climatic impacts of greenhouse warming
- summarize model predictions (rise in global-mean temperature, latitudinal
and
seasonal distribution, invigoration of hydrologic
cycle)
