Aims of this episode:
- Identify the main pollutants from fossil fuel burning;
- Describe the effects of pollutants on the environment;
- Understand the causes and effects of global warming.
Types of Pollutants
There are more pollutants than just Carbon Dioxide. When fossil fuels are burnt, many different chemicals are given off and most of these either contribute to global warming or are toxic to humans and animals. Click here to read about some of the less well known pollutants.
Global Warming is the gradual increase in global temperatures caused by the Sun’s heat getting trapped in the atmosphere by the pollutants given off primarily due to human activity. 2016 was an important year for global warming – click here to find out why.
Whilst it is called ‘global warming’ the effects are more varied, so we use the term ‘climate change’ to describe what we see. Here is a map showing you how the climate is changing around the world.
We found a video that explains a bit more about how global warming works – click here.
So, what can you do? Sky News produced a quick video to give you some ideas.
