Question
Though greenhouse effect is natural but still today’s climate change has become a serious problem. Why?
Because unexpected changes to the climate system may have accidental outcomes that may cause challenges for societies.
- 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 a small increase in greenhouse gas concentration can have a great impact on rise in temperatures.
Because unexpected changes to the climate system may have accidental outcomes that may cause challenges for societies.
Because once greenhouse gases released into the atmosphere, they remain effective for many years, making it hard to reverse the process.
Hint:
Greenhouse effect is a serious problem because human's over emission of greenhouse gases has affected the process
The correct answer is: Because humans have modified a natural method and exaggerated changes that might normally happen over millions of years.
Concentration of greenhouse gases has increased in the atmosphere due to human activities and therefore it has exaggerated the process.
