Question
The spatial coverage of sea ice will decrease as carbon dioxide levels rise. As a result, the reduced sea ice extent is a ________.
- Positive feedback on surface temperature because it has a higher albedo than the ocean.
- Positive feedback on surface temperature because it has a lower albedo than the ocean.
- Because sea ice has a lower heat capacity than the ocean, there is positive feedback on surface temperature.
- Both B and C are true.
The correct answer is: Positive feedback on surface temperature because it has a higher albedo than the ocean.

We know that the greenhouse effect is natural, then why its increase has become a serious issue?
- Because a slight increase in greenhouse gas concentration can have a significant impact on rise in temperatures.
Because humans have modified a natural method and exaggerated changes that might normally happen over millions of years.
Because once greenhouse gases released into the atmosphere, they remain effective for many years, making it hard to reverse the process.
Because Unexpected changes to the climate system may have accidental outcomes that may cause challenges for societies, such as severe weather, spread of diseases, a decrease in marine life, or changes in ocean circulation patterns.
