Is the climate stable?

If I change _____, will the system still work the same? �
How quickly are things changing? �
If I were to come back ____ �seconds/days/years from now, how much �would things have changed? �
Are inputs and outputs steady/constant, or �are there patterns and changes? �
Is the rate of change speeding up or slowing �down? �
Does a little 'cause' result in a little 'effect', or �can a slight change/small 'cause' result in an unexpectedly large effect? �
