- Rising sea levels. - Ice cores that show the levels of gases in the air. - Extreme weather events are becoming more frequent. |
|
|
What are some ways of reducing the impact of climate change? |
- Defend and protect coastal areas from flooding. - Encourage research into crops that will withstand drought and diseases. - Develop more efficient ways of predicting and preparing for extreme weather events. |
