Correct Answer:
C. 2Β°C
Correct answer: 2Β°C. The Paris Agreement aims to hold warming to well below 2Β°C above pre-industrial levels, while pursuing efforts to limit it to 1.5Β°C.
Background: Climate risks generally become more severe as global temperatures rise, which is why the 1.5Β°C aim matters.
- 1Β°C: 1Β°C is not the target; warming has already passed about 1Β°C above pre-industrial levels.
- 1.5Β°C only: 1.5Β°C is the aspirational limit pursued, but the headline goal is well below 2Β°C, so 'only' makes this wrong.
- 3Β°C: 3Β°C is far above the Paris limits.
Did you know? The 1.5Β°C figure is the 'pursue efforts' part of the goal.
Memory trick: Well below 2, pursue 1.5.
