Answer 1

2: Leaders convened to discuss the pressing issue of climate change and how nations can work together to combat it.

Step-by-step explanation:

196 parties gathered in Paris on December 12 2015 to sign the Paris Climate Accord that became effective on November 4 2016. These nations gathered with the intent of significantly reducing global warming levels to below 2 degree Celsius. They hope that by 2050, the world climate level should be at a neutral level.

The issue of climate change is one that affects all lives on the earth and that threatens human existence. That is why these nations are united in the singular objective of combating the climate change.
