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 greenhouse gas emissions so that the rise in average global temperature by the end of this century does not exceed 2 degrees C or even 1.5 degrees 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 1 is incorrect: The agreement did not "go into effect in 2017." It was adopted in Dec 2015, signed in April 2016, and legally entered into force on November 4, 2016, after the "55/55" threshold (55 countries representing 55% of global emissions) was met. Statement 2 is correct: This is the core "temperature goal" of the Paris Agreement: keeping the increase well below 2°C and pursuing efforts to limit it to 1.5°C above pre-industrial levels. Statement 3 is incorrect: While the agreement acknowledges "Common But Differentiated Responsibilities" (CBDR), the financial commitment was $100 billion per year by 2020, not $1000 billion.
