T2 w3 causes of climate change
This document provides an overview of climate change, including its causes and key concepts. It defines climate change as variations in global climate patterns over long periods, including changes in temperature and seasonal shifts. Climate change can occur through global warming, which is an increase in global temperature, or global cooling, which is a decrease. The greenhouse effect is the natural trapping of the sun's heat by greenhouse gases like carbon dioxide and water vapor. However, increased greenhouse gases from human activities like burning fossil fuels are enhancing the greenhouse effect and causing additional global warming. The document examines natural and human factors that influence climate change and provides a quiz to assess understanding.

- 10. qns 1 Climate Changeis the same as Global Warming 5:20 True? False? Climate change = climate patterns changing. It’s not just warming. Includes cooling. Global warming = increase in temperature ONLY.
- 11. qns 2 Climate Changeis caused by humans only. True? False?
- 12. qns 2 Climate Changeis caused by humans only. True? False? There are natural causes to climate change.
- 13. qns 3 Climate Changeis a recent phenomenon True? False?
- 14. qns 3 Climate Changeis a recent phenomenon True? False? Earth Climate has been changing as a cycle naturally for millions of years.
- 15. Temperature of theworld has been changing throughout history naturally.
- 16. There were timeswhere Earth was cooler than today = ice age
- 17. qns 4 Since therehas been climate change throughout history, there is nothing to worry. True? False?
- 18. qns 4 Since therehas been climate change throughout history, there is nothing to worry. True? False? The recent changes since 1881 is more significant than what happened in history.
- 20. Climate Change has beenwithin a small temperature range
- 21. Climate Change has beenwithin a small temperature range But since 1881, the increase is higher than what happened in history

- 23. climate change = changes/ variations in global climate patterns in the long term
- 24. climate change = changes/ variations in global climate patterns in the long term = not just changes in average temperature. Eg: Changes in when the seasons occur is also climate change!
