Lesson details

Key learning points

  1. Increasing average global temperatures leads to an increase in sea levels.
  2. Increasing average temperatures cause more powerful convection currents, increasing the number and severity of storms.
  3. Increasing average temperatures can affect atmospheric air streams and change weather patterns.
  4. Changes of human behaviour can lead to smaller increases in global temperature.
  5. Climate engineering may enable humans to reduce global temperatures through the application of technologies.

Common misconception

Climate change only leads to hotter weather. Human activity has a negligible impact on climate change.

Explain the diverse effects of climate change, including extreme weather. Highlight the significant role of human activity in accelerating climate change.


  • Global warming - Global warming is an increase in Earth’s global temperatures, likely caused by more greenhouse gases in the atmosphere.

  • Sea ice - Sea ice is formed, grows and melts into the oceans. Sea ice floats on the ocean surface and contains less salt than sea water as the salt is ‘pushed out’ of the ice structure.

  • Convection currents - Convection currents are the transfer of heat in a gas or liquid, caused by differences in density and temperature.

  • Climate - The long-term weather conditions in an area are known as the climate.

  • Climate engineers - Climate engineers use technology as part of a large-scale intervention to alter the climate and limit the impacts of climate change.

Seas are smaller than oceans. The sea connects an ocean to land.

Order the stages of carbon capture and storage.
1 - Carbon dioxide is collected before it is released into the atmosphere.
2 - Carbon dioxide is piped underground.
3 - Carbon dioxide is stored in old oil and gas fields and coal mines.
