Global warming: "Titanic" city
Good news: out of all of the climate change scenarios suggested by the UN, RCP2.6 has worked out, that this is the most optimistic one. All States have realised the seriousness of the global warming threat and rallied their forces to work on common goals.
Bad news: it's still far from a happy ending. The Sea level has risen by dozens of centimetres, the Earth's surface temperature has increased by almost one degree. Floods are becoming more frequent. Rich and experienced countries like Denmark and the Netherlands have time to build a protective fence and manage to save coastal communities from flooding.
