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.

1. Statement 1 is incorrect. The Paris Agreement was adopted by consensus by the 196 Parties to the UNFCCC on 12 December 2015. It was opened for signature later. Furthermore, the agreement entered into force on 4 November 2016, not in 2017, after meeting the threshold of ratification by at least 55 Parties accounting for 55% of global greenhouse gas emissions. 2. Statement 2 is correct. This statement accurately reflects the central aim of the Paris Agreement, as stated in its Article 2: Holding the increase in the average global temperature to well below 2°C above pre-industrial levels and pursuing efforts to limit the temperature increase to 1.5 °C above pre-industrial levels. 3. Statement 3 is incorrect. While the Agreement reaffirms the obligations of developed countries, the specific financial commitment mentioned is inaccurate. The commitment (originating prior to Paris but reiterated) was for developed countries to jointly mobilize USD 100 billion per year by 2020 from public and private sources to address the needs of developing countries. The amount stated ($ 1000 billion) is incorrect, and the term 'donate' oversimplifies the mobilization goal. Also, the explicit acknowledgement of sole 'historical responsibility' is often nuanced as 'common but differentiated responsibilities'.
