  1. Emil

    Puh, der Asphalt glüht förmlich! Und was misst du denn da, Kalle?

    Translation

    Phew, the tarmac is practically glowing! And what are you measuring there, Kalle?

  2. Kalle

    Das Stadtklima. Auf dem Parkplatz achtunddreißig Grad, hier unter den Platanen nur dreißig.

    Translation

    The urban climate. Thirty-eight degrees in the car park, only thirty here under the plane trees.

  3. Emil

    Translation

    Eight degrees less? Just because the trees give shade?

  4. Kalle

    Nicht nur. Eine Platane verdunstet Hunderte Liter am Tag, und die Verdunstung kühlt spürbar.

    Translation

    Not only. A plane tree evaporates hundreds of litres a day, and the evaporation has a noticeable cooling effect.

  5. Emil

    Translation

    And the tarmac just heats up, right?

  6. Kalle

    Eben. Wegen der Versiegelung sind die Flächen sogar nachts noch heiß. So wird die ganze Gegend zur Hitzeinsel.

    Translation

    Exactly. Because the ground is sealed, the surfaces are still hot even at night. That's how the whole area becomes a heat island.

  7. Emil

    Deshalb schlafe ich bei jeder Hitzewelle so schlecht. Bei mir in Mitte kühlt es nachts kaum ab.

    Translation

    That's why I sleep so badly in every heatwave. Where I live in Mitte it hardly cools down at night.

  8. Kalle

    Mitte ist halt fast komplett versiegelt. Man müsste Höfe entsiegeln und Dächer begrünen - jede Begrünung hilft dem städtischen Klima.

    Translation

    Mitte is just almost completely paved over. You'd have to depave courtyards and green the roofs - every bit of greenery helps the urban climate.

  9. Emil

    Und die Bewässerung? Bei dieser Hitze vertrocknen junge Bäume doch.

    Translation

    And the watering? Young trees dry out in this heat.

  10. Kalle

    Deshalb gieße ich täglich die junge Linde da drüben. Sie ist erst drei Jahre alt.

    Translation

    That's why I water the young linden over there every day. It's only three years old.

  11. Emil

    Ein Wildschwein mit Gießkanne? Darf ich heute mit? Das will ich sehen.

    Translation

    A wild boar with a watering can? Can I come along today? I want to see that.

  12. Kalle

    Gern. Aber erst mal ab auf die schattige Bank - du glühst ja wie der Asphalt.

    Translation

    Sure. But first off to the shady bench - you're glowing like the tarmac.
