Greenhouse effect and climate change in the

Carbon dioxide is also known as "greenhouse gas". Carbon dioxide, water vapor and tiny amounts of other gases protectively envelop the earth.

This shell "swallows" the sun’s rays and throws them back at the same time. The warmth remains in the atmosphere like in a greenhouse. As a result, it is 15 ° C warm on Earth.

Without this natural protective cover, the temperatures would be around -18 ° C. Life on earth would not be possible. In the primeval special you learn more about the formation of the earth.

carbon is the element in nature that most often combines with other substances. In a chemical formula, carbon is combined with a C shown. Just like oxygen, all living things need the element carbon as a raw material for other building blocks of life such as sugar, starch, cellulose, fats, proteins, etc.
Carbon is not a gas and not a metal. However, a diamond is e.g. B. Carbon in crystal form and belongs to the minerals.

carbon dioxide is a combination of carbon and oxygen. Hence the chemical name CO2. It is a gas that you can neither see nor smell. In contrast to oxygen, it tastes slightly acidic. Carbon dioxide has a major impact on the life of this earth. It is stored in huge quantities in the sea and in limestone. Carbon is also contained in coal, natural gas and oil. When these substances are burned, for example when driving or heating, carbon dioxide is generated. At the same time, it is the waste product of breathing and the substance from the plant through which photosynthesis Produce oxygen.

Then man invented the steam engine, the steam boiler of which is operated with coal and produced CO2 as waste. The age of industrialization began. Is 300 years later list of the technical achievements that continuously blow carbon dioxide and other pollutants into the atmosphere: factories, airplanes, cars, heaters and computers etc. In our "greenhouse earth", the temperatures rise. By the year 2100, temperatures should average between 16.4 ° C and 20.8 ° C.

This has consequences for life on earth:

Glaciers and polar caps are melting. As a result, sea levels rise. If sea levels rise, the habitat is flooded and thus destroyed. Floods and heavy rainfall are increasing worldwide, as more and more water is in the earth’s water cycle. The weather and the climate are changing. ecosystems lose their balance and are destroyed.

Within the biosphere everything living is in constant exchange with the inanimate environment of air, water, soil and other substances. Communities and their surroundings form an ecosystem, a mini biosphere. A dead tree trunk can be an ecosystem just like an entire deciduous forest. Both have one thing in common: all living beings are dependent on each other and connected by nutrient cycles. This applies to the bacteria in the forest floor as well as to the 30 meter high beech, in which a black woodpecker is breeding.

While people are fighting against water masses in one hemisphere, there is a lack of precious water in the other hemisphere. The deserts continue to spread. There are strong, long-lasting heat waves and great drought – also in southern Europe. But above all: where there is no or too much water, no plants grow. Neither fruits and vegetables nor cereals can be grown. Even more people in the world will go hungry and live in poverty.
Climate researchers and environmentalists The whole world are therefore calling on all countries in the world to reduce CO2 emissions.
