Following statements are made regarding global warming.
A. Global warming is the long-term heating of Earth's surface observed since the pre industrial period due to human activities, primarily fossil fuel burning, which increases heat-trapping greenhouse gas levels in Earth's atmosphere.
B. Global warming causes climate change, which poses a serious threat to life on Earth in the forms of widespread flooding and extreme weather.
Which of these statements are correct?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is Option 3 i.e. Both A & B
- Both statements A and B about global warming are correct:
- A. Global warming is indeed the long-term heating of Earth's surface observed since the pre-industrial period.
- It is primarily driven by human activities, particularly the burning of fossil fuels, which increases the levels of greenhouse gases in Earth's atmosphere.
- These gases trap heat and lead to a gradual increase in global temperatures.
- B. Global warming is one of the primary factors contributing to climate change.
- As the Earth's average temperature rises, it has far-reaching effects on the planet's climate.
- This, in turn, poses serious threats to life on Earth, including consequences such as widespread flooding and more frequent and severe extreme weather events
