The natural greenhouse effect

Summary[edit]

Description
Deutsch: Unsere Erde ist umgeben von einer Hülle aus Gasen. Eines dieser Gase ist CO2, Kohlenstoffdioxid. Es hat eine ganz bestimmte Funktion. CO2 bildet eine Art Schutzschicht um die Erde herum, die verhindert, dass es auf ihr zu kalt wird. Die Sonne scheint durch die Atmosphäre hindurch und erwärmt Boden und Meere. Die Erde strahlt diese Wärme wieder ab. Das CO2 sorgt jetzt dafür, dass auf dem Rückweg nicht die ganze Wärme ins Weltall entweichen kann. So wie ein dicker Schal im Winter. So bleibt es auf der Erde warm genug, dass wir darauf leben können. Man nennt das den natürlichen Treibhauseffekt. Ohne die CO2 Schicht wäre es viel zu kalt auf der Erde. Problematisch wird CO2 wenn davon zu viel entsteht. Wie zum Beispiel durch Fabriken, Autos oder auch Strom der durch Kohlekraftwerke erzeugt wird. Die CO2 Schicht wird immer dichter und immer mehr Sonnenwärme bleibt in der Atmosphäre gefangen. Dadurch heizt sich die Erde auf und das hat Folgen für die Umwelt.
English: Our earth is surrounded by a shell of gases. One of these gases is CO2, carbon dioxide. It has a very specific function. CO2 forms a kind of protective layer around the earth that prevents it from getting too cold. The sun shines through the atmosphere and warms the soil and oceans. The earth radiates this heat back. The CO2 now ensures that not all the heat can escape into space on the way back. Just like a thick scarf in winter. This keeps the earth warm enough for us to live on. This is called the natural greenhouse effect. Without the CO2 layer, it would be far too cold on earth. CO2 becomes problematic when too much of it is produced. Such as by factories, cars or electricity generated by coal-fired power plants. The CO2 layer is getting denser and more and more heat from the sun is trapped in the atmosphere. As a result, the earth heats up and this has consequences for the environment.
