UGC NET Questions (Paper – 1)

The Paris Agreement,adopted in 2015,sets a goal of keeping global temperature rise this century well below 2°C above pre industrial levels and pursuing efforts to limit it to 1.5°C. It relies on nationally determined contributions from all parties. The agreement represents a major global consensus on climate action. Therefore the description in the question points clearly to the Paris Agreement.

Option A:
The Rio Declaration consists of a set of principles on environment and development from the 1992 Earth Summit. It does not specify quantitative temperature limits. Hence it does not match the detailed climate target mentioned in the stem.

Option B:
The Doha Amendment relates to the second commitment period of the Kyoto Protocol. While it adjusts emission targets,it is not framed around a specific temperature limit goal. Therefore it is not the best answer here.

Option C:
The Cartagena Protocol deals with biosafety concerning transboundary movement of living modified organisms. Its focus is on protecting biodiversity from risks posed by biotechnology,not global temperature control. Thus it is unrelated to the description given.

Option D:
The Paris Agreement explicitly articulates the 2°C and 1.5°C temperature thresholds as collective goals. Because the question cites this exact aim,it can only refer to the Paris Agreement.
