Topic Introduction

Global climate change is an increasing concern. A basic understanding of the science underpinning climate change is important. In this lecture, we will introduce students the concepts of weather, climate, climate variability, climate extremes, and climate change. We will also explain the major causes of climate change, and model projections of future climates based on various greenhouse-gas-emission scenarios. Options and challenges to fight against climate change will also be covered in this lecture.

By the end of this topic, you should be able to:

  • Explain the difference between weather and climate, and between climate variability and climate change
  • Describe the relationship between the mean and the extremes of a climate variable.
  • Identify the major causes of climate change.
  • Recognize the seriousness of climate change and its impact.
  • Describe the options and challenges in fighting against climate change.
  • Recognize the seriousness of climate change and its impact.
