Chapter 4: Environmental Change

After completing this chapter you will understand:

  • How environmental change can be in a steady state, can be shifting back and forth (oscillating), or evolving.
  • How rates of environmental change vary, from those happening in seconds to those taking many millions of years to complete.
  • How the scale of environmental change varies, from local changes in a pond or valley, to those that change the entire world.
  • How environmental change in one Earth system can affect other Earth systems often distant in both space and time.
  • How science and environmental monitoring help to understand environmental change.
  • How environmental change can have both positive and negative impacts and be challenging to understand.
