The urban climate often differs from the rural climate. Cities are usually denser, less green and produce more emissions. That is why the average temperature is often higher there and the wind blows differently than on land. At CEN, scientists are investigating both how cities can protect the climate and how cities can adapt to climate change.
Adapting to Climate Change: Cities Will Have to Fundamentally Transform

During heavy rainfall events, when a certain amount of rain is exceeded in just a short time, cities can face challenges of urban flood risk. However, this depends not only on the amount of rainfall, but also on the land’s ability to deal with this water: how absorbent is the urban soil? Is...
Putting Urban Trees to the Test

Providing shade and cooling the air, trees are vital to the quality of human’s life in Hamburg. However, our trees face challenging conditions along streets – and with climate change. In particular, freshly planted trees are thus subjected to stress, indicated by slow growth and failure gain...
Climate-adapted and Worth Living In: Urban Green Spaces for Everyone

In Germany, ca. 77 percent of the populace live in cities. There, new buildings are constructed, people heat their homes, and waste is produced. In addition, cities are particularly affected by the impacts of climate change – above all, heat, extreme precipitation and flooding. Although many...
Using Wotan’s help to see how the wind blows
Sawing, gluing, and hunting down data: it took months before my miniature version of Hamburg was ready. First I had to find out what each and every building between the Elbphilharmonie concert hall and the Großmarkt (wholesale market) looked like – how tall it was, what its roof was shaped...

Stressed street trees: Lindens, oaks, or maples facing premature death in the future
Rambling through Hamburg and its environs, you will discover a landscape sculpted by the ice ages. Glaciers of the past pushed large amounts of scree shaping today’s hilly countryside northeast of the City. Meltwater leached the glacial Elbe valley and wind-blown sand deposits piled up into...
Hamburg-based “agents” in the service of climate research

My agents don’t wear dark sunglasses, and most don’t even drive a car. Except for Bob: when he needs to go somewhere, he prefers to drive there. In contrast, Alfred likes to bike through the city (as long as it’s not raining), and Earl tends to use public transportation.
