Impact of Human Activities on Climate

Kevin Trenberth

Former Coordinating Lead Author of the IPCC

In the earlier videos of this pathway, Kevin Trenberth introduced the climate system and Earth’s Energy Imbalance (EEI). In this video, Kevin explains how human activities have contributed to this increasing imbalance and then covers some terms such as aerosols, feedbacks and then covers the importance of climate models.

Impact of Human Activities on Climate

14 mins 14 secs

Overview

The Earth’s energy is increasing at a scary pace. This is responsible for extreme weather events that we are witnessing more frequently. It is vital to understand exactly the human induced contribution to this and also terminology around the other external factors that affect the climate system and how the system itself responds to these changes. It is equally important to model all these changes and ensure the right policies and actions are taken to stop warming.

Key learning objectives:

  • Comprehend how human activities have contributed to global warming

  • Understand what aerosols are

  • Understand how aerosols influence the climate system

  • Outline the need for climate modelling
