Answer:
2. Leaders convened to discuss the pressing issue of climate change and how nations can work together to combat it.
Explanation:
Nearly 200 countries in the world, precisely, 196 countries convened in Paris in December 2015 to discuss the problem of climate change that affects everyone on the globe. This agreement falls within the framework of the United Nations Framework Convention on Climate Change. The agreement at this convention was to reduce the temperature emitted at a global level to an average of 2° Celsius or an equivalent of 3.6° Fahrenheit.
The ultimate goal however is to attain a limit of 1.5° Celsius or its equivalent of 2.7° Fahrenheit. When these goals are reached our climate will be restored and living things will have a better chance of survival.
