UPSC 2016: With reference to the Agreement at the UNFCCC Meeting in Paris in 2015, which of the following statements is/are correct? 1. The Agreement was signed by all the member countries of the UN and it will go into effect in 2017. 2. The Agreement aims to limit the greenhouse gas emissions so that the rise in average global temperature by the end of this century does not exceed 2°C or even 1.5°C above pre-industrial levels. 3. Developed countries acknowledged their historical responsibility in global warming and committed to donate $1000 billion a year from 2020 to help developing countries to cope with climate change. Select the correct answer using the code given below.

Statement 2 is correct: the Paris Agreement seeks to keep the rise in global mean temperature well below 2 °C and to pursue efforts to limit it to 1.5 °C above pre-industrial levels. Statement 1 is wrong because the Agreement entered into force on 4 November 2016 (after 55 countries with 55 % of emissions ratified it), not in 2017, and not all UN members had signed on the adoption day. Statement 3 is wrong because developed countries reiterated the Copenhagen pledge to mobilise USD 100 billion—not USD 1000 billion—per year for developing nations from 2020 to 2025.
