Activists “flooded” New York because of Trump’s refusal to believe in global warming.

The authors of Claire&Max channel have decided to show the consequences of global warming by using New York as an example. They modeled how one of the biggest metropolises in the world would look like after the flood which would be caused by the melting of glaciers.
