Decisive days at the COP23 climate conference: Politicians have defined the next steps in the fight against global warming. German Chancellor Angela Merkel spoke at the start of the ministerial round of humankind's destiny. Industrialized nations in particular must work harder to reduce their emissions. In Bonn, Germany, 25,000 people from around the world gathered for this purpose.
The core issue: How to reach the goal of the Paris Agreement to limit global temperature increase to maximum 2 degrees Celsius? For populations in coastal areas, the water is literally lapping at their doors; they need swift action. So at COP23, it's also about visions for keeping the planet habitable. Climate change is being felt – as are worldwide reactions on the part of politicians, researchers – and last but not least, regular people.
