Our paper estimates possible impact of urban civilization on the global climate. An effective model is used of the ''heat island'' centered above the city, it describes the temperature distribution over the urban area of a radial-circular structure. Contribution was estimated of the big cities into the median temperature of the Earth. It is shown that heat production in the radial-circular cities is able to deteriorate the life conditions at the center of a city with great population. According to the model, contribution from the update cities into the global median temperature is evaluated as ~0.04 ° C. Simultaneously, a thousand of cities of the 10 million inhabitants each is able to raise the global median temperature by 0.4° C.
