urbanization and growing cities is increasing over the last years
In average cities are growing about 2,07%1 every year. This will lead to huge mega cities with lots of people and buildings.
but global warming leads to increased temperatures in cities
Compared to the country area, cities tend to be hotter and the trend is increasing. A bigger amount of exhaust gases, more tarred surfaces and air conditioning are among other things reasons for warmer temperatures inside cites.

warmer cities effect the productivity
Dramatic impact will especially become visible in the following areas: The radar chart is about the sectors with the most losses in gross value added. The bar chart below highlights different scenarios to prevent these losses.

changing the way of life to avert losses
Apparently losses increase due to higher temperatures within cities. We could change this by adopting our working conditions by one of the following scenarios.
go green to reduce heat in cities
Air conditioning is the most obvious improvement for productivity. On the other hand it also is the strongest reason for hotter cities. It can raise temperatures inside cities by more than 1°C. A combination of the best working hours and installing solar blinds on the outside of windows is an effective way to avert losses. Most important is not only fighting the hot temperatures but also making our cities greener by more plants, parks and water areas. This will reduce the root cause of heat and brings us to less pollution in the air.
