Rapid Ice Melt: Do The Coastal Towns Sink Soon In The Sea?
Date&Written by: (25.3.2006- Karan)

Ground electrode warming threatens coasts and plant world
The climatic change accepted dramatic consequences than so far. According to newest studies wide inundations threaten by the melting of the polar ice. In Germany square kilometers could be located under water, also coastal towns are concerned up to 14,000. In addition are threatened over half of all plant types in Europe of becoming extinct.

Sea could rise six meters
According to a study in the specialized journal "Science" count US researchers on an increase of the temperature on earth around at least 2.22 degrees Celsius up to the year 2100, if the present heating up continues. The ice covers in Greenland and in the Antarctic melt after the investigations faster than so far meant. This will presumably lead to a rise of the sea level of at least six meters.

14,000 square kilometers Germany under water?
In Germany a rise of the sea would already mean around a meter that 14,000 square kilometers coast and hinterland at north and Baltic Sea are inundated. That corresponds about four per cent to the entire national surface and an area, in which over three million Federal citizen live. World-wide numerous coastal regions and cities would be threatened by the higher sea level. The recent progress report of the United Nations assumes so far the water level of the weltmeere will add maximally 88 centimeters in this century. Due to the new results these numbers would have to be revised.

Geologic history could repeat itself
Their realizations derive the scientists from observations over the interglacial period before 129.000 to 116,000 years. The researchers of the University of Arizona and national centers for the Atmospheric Research (NCAR) to Colorado pointed that the arctic summers will be possibly as warm in the year 2100 as before nearly 130,000 years. At that time the sea level was six meters higher than today. "these ice covers melted before and the sea levels risen", say to bed petrol Bliesner, Wissenschaftlerin at the NCAR. "the warmth, which was necessary for it is not larger than under much present conditions."

Of Europe plant world is threatened
Apart from the danger of flooding the ground electrode warming has still further consequences for the environment. After an investigation of the environmental research center Leipzig-resounds is seriously threatened over half of all plant types in Europe by the climatic change. Particularly the strongly specialized Gebirgsflora would carry serious damage of it. Concerned above all large parts of the Mediterranean area and Eastern Europe are beside the alps and Pyreneeses. Smaller however the losses of the diversity of species are in Scandinavia and in the range of the Atlantics.

Climatic prognoses for 2080
The scientists had computed the influence of different climatic prognoses on 1350 European plant types. These models go from a rise of the carbon dioxide concentration in the atmosphere up to the double today's values and a middle temperature out, which will lie in the year 2080 up to four degrees over the today's value. First results of the research project ALARM are presented at present to the conference of UN to biological variety in the Brazilian Curitiba.
