Point of no return

The UN Climate Summit has kicked off in Madrid, and leaders from all around the world are discussing the best ways to deal with climate change. UN Secretary-General Antonio Guterres has taken the world's major economies to task for failing to reduce carbon emissions, and warns that the "point of no return" is fast approaching. Guterres says the global push to stop climate change has been "utterly inadequate." While the focus on climate change is often on the largest countries, it's the smaller island nations that are feeling the most severe and existential effects of a heating planet. Spain climate talks seems to narrow the rich-poor gap, the gap between the big and smaller countries.
