2-4: Enhanced Greenhouse Climate, Transient Climate Simulations
Importance of this Unit to the Course
The equilibrium climate models described in the previous
unit are somewhat simplified to give quick results of possible future climates. They overlook a key
factor that the ocean, atmosphere and ice change at different rates when external heating of the
climate system changes. Better evaluations of climate models and better projections of future
climates can be done with transient models. Transient models give better estimates about when we
can expect significant climate changes to occur.
- To understand how future increases in greenhouse gases will cause
temperatures and precipitation patterns to change.
- To understand the range and causes of uncertainty in climate models
and how these relate to uncertainties in projections of economic growth.
