C13.4 Global Climate Change

Question 1

How are rising sea levels caused by rising levels of greenhouse gases?

Answer 1

Greenhouses gases absorb and re-emit radiation - this caused ice caps to melt
Therefore this can cause flooding of low-lying land and increased coastal erosion

Question 2

What can changes in temperature cause?

Answer 2

Can lead to changes in distribution of rainfall
Can have impacts on the food-producing capacity of different regions
Regions that are already dry will get more drier and the place will get less suited to growing crops

Question 3

What is a carbon footprint?

Answer 3

The carbon footprint of a product, service , or event is the total amount of CO2 and other greenhouses gases emitted over its full cycle

Question 4

What is carbon capture and storage?

Answer 4

Involves using metal pipes to pump CO2 into underground storage areas - which therefore reduce the amount of CO2 in the atmosphere
