The document discusses the impacts of global warming on large cities in developing nations. It notes that while cities occupy just 0.4% of land, they are home to half the world's population. The urban populations in Asia and Africa are expected to double in the coming years. Of the 33 largest cities in 2015, 21 are coastal and vulnerable to rising sea levels from climate change. Tokyo, Mexico City, New York, Sao Paulo, Mumbai, Delhi, Kolkata, Shanghai, Jakarta, and Buenos Aires are identified as particularly at risk from storms and earthquakes.

2. GLOBAL WARMING IS WORSE IN LARGE CITIES IN THE THIRD WORLD

3. The cities of the world, large, small and medium-sized, are the main front in the global battle against climate change

4. Cities occupy just 0.4% of the land surface, but they concentrate half the world population, 3,200 millions of souls, according to United Nations

5. It is expected that the urban population of Asia and Africa to double over the next few years, and if the trend is not reversed, will reach 3,400 million people in 2030.

6. Of the 33 cities in the world will have more than eight million people in 2015, 21 are on the coast or as close to it that will be forced to take drastic measures against the rising sea level due to rising temperatures

7. The study identifies Tokyo, Mexico, New York, Sao Paulo, Bombay, Delhi, Calcutta, Shanghai, Jakarta and Buenos Aires as the crowds more vulnerable to storm surges and earthquakes.
