Why Berlin needs cold air to breathe – and why city greenery is so important to achieve the climate targets for 2050

A geodata analysis by the Berlin Senate Department shows how the movement of cold air on open spaces influences the climate in the city. According to a report by the newspaper Berliner Morgenpost, these open spaces and existing urban green spaces must be treated with great care – especially in order to achieve the climate targets for 2050.

As the report in the Berliner Morgenpost describes, so-called cold air corridors are an important part of the urban climate system. They connect areas where cold air is created with areas in which the cold air can flow – the so-called spheres of action.

According to Berliner Morgenpost, the analyses of the geo-database provide recommendations as to where new construction areas can be created, without the surroundings having to be classified as poorer in terms of urban climate.

In view of the expected global warming in Berlin by 2050, the existing urban greenery must be treated with great care, the experts concluded in a conversation with the Berliner Morgenpost. In the densely built-up districts, experts of the Senate administration also recommend an increased greening of city squares, courtyards, facades and roofs. According to the experts, this could reduce overheating, increase humidity and bind dust.
