From Vatican News:
I would like to thank the United Nations Secretary-General, Mr António Guterres, for convening this meeting and for drawing the attention of Heads of State and Government – and of the entire international community and world public opinion – to one of the most serious and worrying phenomena of our time: climate change.
This is one of the principal challenges we have to face. To do so, humanity is called to cultivate three great moral qualities: honesty, responsibility and courage. With the Paris Agreement of 12 December 2015, the international community became aware of the urgency and need for a collective response to help build our common home. However, four years after that historic Agreement, we can see that the commitments made by States are still very “weak”, and are far from achieving the objectives set.
