Why this matters
Ein Interview mit der Stadtklimaforscherin Dr. Keller über Hitzeschutz in Städten: was sich in zehn Jahren verändert hat, warum die Tropennächte wichtig sind, welche Maßnahmen wirken (Bäume, Gründächer, Wasserspiele), warum sich alte Bäume nicht einfach ersetzen lassen, wo Anwohner sich sträuben, wer am stärksten gefährdet ist und was kleine Städte tun sollten. Die Übung gibt acht Aussagen vor, die du markierst: stimmt (sie sagt es, vielleicht mit anderen Worten), stimmt nicht (sie sagt das Gegenteil oder lehnt es ausdrücklich ab) oder nicht gesagt (sie geht nicht darauf ein). Bei der dritten Antwort liegen Hörende am häufigsten falsch: Ein Hinweis ist keine Aussage, und „ermutigende erste Ergebnisse“ heißt nicht „bewiesen“. Achte auf die Einschränkungen: zumindest auf dem Papier, allerdings weniger, solange, ich will nicht behaupten. Jede davon ist der Schlüssel zu einer Aussage.
Translation
Presenter: Dr Keller, you have been researching for fifteen years how cities deal with heat. What has changed in that time? Dr Keller: Ten years ago heat protection was a marginal topic that at most a few urban climatologists dealt with. Today almost all larger cities have a heat action plan, at least on paper. Whether it is actually implemented is another question. Presenter: Does climate change play a role here, or are hot summers simply weather? Dr Keller: There have always been individual hot days. What is new is that heat periods are becoming more frequent and lasting longer – and that cities hardly cool down at night any more. It is precisely these tropical nights that are the real strain on the body. Presenter: So which measures work best? Dr Keller: Trees, quite clearly. Nothing cools a street as reliably as a closed canopy of leaves. In our measurements the difference in surface temperature was up to ten degrees. Trees also evaporate water and so cool the air as well. Green roofs help too, though less than is often claimed – for the people on the pavement they do hardly anything. Water features and fountains are effective but expensive to maintain. Presenter: But new trees take decades before they really give shade. Dr Keller: That's right, and that's why I think it is disastrous to fell old trees for building projects. You cannot replace a healthy tree with a large crown with ten young trees, at least not in the next thirty years. Presenter: How do citizens react to such plans? Dr Keller: Acceptance is high as long as nobody loses their parking space. As soon as a tree is to replace a parking bay, it gets difficult; then there are petitions and packed public meetings. I don't want to claim that drivers are the problem – but the competition for space in narrow streets is real. Presenter: Who is actually most at risk in the heat? Dr Keller: Older people who live alone, especially in top-floor flats. Many don't even notice that they are drinking too little. Some cities therefore send volunteers on home visits during a heatwave, and the first evaluations are encouraging. Presenter: What do you advise smaller municipalities that have little money? Dr Keller: Start small: one street, twenty trees, measure for three years. The data will then convince by themselves – the local council too. And anyone who involves the residents from the start saves themselves a lot of trouble later.
