In order to make statements about future changes in climate, one must map the climate processes very precisely using a model calculation. Among the mapped variables include the development of new population growth, technology, topography, political interests, etc. Now you can create in all possible scenarios, boundary conditions and calculate the development. Even if the variation, selection and quantity of the sizes used for the calculation, giant appears to be strong, a further increase in greenhouse gas concentrations will very clearly. The model calculations show that up to the year 2100 of the CO2 emissions in our atmosphere will have more than doubled. Precipitation over the world will change the precipitation patterns and the water cycle will be intensified by the warming.

A higher evaporation rate in the summer months in countries far from the coast to be more droughts occur. On the other side will be stronger by Precipitation occur more flooding. Cross, one can say that is expected in many parts of the world, with heavy rain. The statement about the future, however, precipitation can not be taken as accurate as the temperature on future changes. The temperature calculated by the model global average temperatures are expected to rise further.

But it is not a typical fluctuation of temperature. A rise of 1.5 – 5.8 C is predicted, and similar variations of recent centuries are thus clearly exceeded. Asked that the temperature fluctuation even move forward at a speed as it is known only from the last ice age ago. So climate change is to recognize very clearly. A logical consequence will be that we must fight with more extreme temperatures. Many hot days and heat waves will be part of our everyday life. The days on which falls below the 0 C – limit take off and Dichtol the difference of night and daytime temperature to converge. Sea level, scientists believe that will have increased cm due to the melting glaciers and expanding the water in the oceans by 2100 the sea level by 10 – 90. As the heat energy can be absorbed only very slowly from the water, the reaction of the oceans and the sea level is rising very slowly thus delayed will continue but with very high probability for centuries.
