Are humans part of the cause?
How bad will it get?
What can we do about it? |
|
|
Term

|
|
Term
| CO2 is stored in many places such as? Destruction of these places results in? |
|
Definition
Peat bogs, forests, etc.
Destruction of these places releases the stored CO2 |
|
|
Term

|
Definition
| Changes in animal, plant distribution and patterns of movement; Changes in local and regional climate/weather; Sea level rising, causing large scale flooding |
|
|
Term

|
Definition
| Industrialized nations are to reduce greenhouse gas emissions and can trade for emissions with other nations |
|
|
Term
| How does changes in atmospheric temperature affect ocean temperature and sea-levels? |
|
Definition
| Increase in ocean temperatures, increase in the sea-level due to ice caps melting |
|
|
