INCREASE OF TEMPERATURE EFFECTS ON WATER

In our everyday’s conversations we talk about global Green house effect problem, rise of temperature, CO2 increase etc. but do we really understand what these scientific theories mean?
The most important Green house effect and the one that should concern us the most is the rise of temperature globally with significant results. As we already know the majority of the earth’s surface is covered with water. Most of it is sea water. Fresh water is found in small quantities in rivers and lakes and the biggest part of it is stored in the Glaciers and in the two poles.
The biggest concern of man today is what will happen if the temperature rises a few degrees. In Copenhagen’s summit not long ago the results were studied especially what will happen if the global temperature rises by 4 degrees Celsius (7 degrees F). The results were astonishing and are shown in the enclosed drawing in the end of the paper.
With high levels of climate change, large areas of the Amazon forest could be lost through either drought stress on vegetation or the uncontrolled spread of fire. This depends largely on whether rainfall will decrease in Amazonia. While some climate models suggest rainfall may increase, some of the more realistic models project severe drying in the Amazon, increasing the risk of major droughts.
Climate change directly affects crop productivity and food production. Changes in the regional differences in climate patterns may widen production and consumption gaps between the developed and developing world. Current assessments are mainly limited to alterations in mean climate, but extreme weather or glacial retreat would potentially accelerate declines in productivity further.
Agricultural yields are expected to decrease for all major cereal crops in all major regions of production, once the global average temperature increases beyond 3 ºC. For some crops the yield could decrease by over 20% at low latitudes, where the...
