Explaination:
As carbon dioxide levels in the atmosphere rise:
• The temperature of Earth rises --> The rate of photosynthesis in plants increases --> More carbon dioxide is therefore removed from the atmosphere by plants, reducing the greenhouse effect and reducing global temperatures
As Earth warms:
• Ice cover melts, exposing soil or water --> Albedo decreases --> More energy is absorbed by Earth’s surface --> Global temperature rises --> More ice melts
Explaination:
As Earth warms, polar ice caps melt releasing large numbers of icebergs into oceans:
• Warm ocean currents, such as Gulf Stream, are disrupted by additional freshwater input into the ocean --> Reduced transfer of energy to poles reduces the temperature at high latitudes -->Ice sheets reform and icebergs retreat --> Warm currents are re-established
Explaination:
What does albedo have to do with feedback loops?
