Climate Change And Human Strategy --- E K Federov : BTECH II SEM UNIT 2

          E.K. Federov says that human beings are increasingly concerned about irreversible changes taking places in the natural environment, especially in regard to climate change. In the course of their scientific and technological progress, human beings have transformed the environment.Despite these developments, the modern life requires balanced understanding and adjustment to climate and other natural elements.

             Now a days we live on the planet which has got neither infinite resilient environment nor its resources inexhaustible. In such circumstances, any human error can lead to very large cumulative error. They are vulnerable to climate change. It is both a consequence and a demonstration of the workings of complex process in atmosphere, the oceans and on land. However, these complex factors do exhibit some continuity and permanence.

            There are several atmospheric and oceanic parameters which are responsible for the overall stability of climate in different parts of the world. They include manmade extreme temperatures, precipitation amounts, seasonal river discharges etc…they vary from one part of the planet to another. Climate is the sum of all these relatively stable characteristics of the atmosphere. Several tens of millions of years ago this situation began to change.

            The temperatures of high latitudes fell gradually. About two million years ago this process accelerated and Arctic temperature dropped sharply. As a result a glacial period had taken place in which repeated advances of ice sometimes reached mid-latitudes with intervening periods when the ice moved back.

            In his views, there are two kinds of factors that cause the climate to change over long periods of time. The external factors might include the variations in the quality of radiation emitted by the Sun or changes in the Earth’s orbit around the Sun. The internal factors include the formation and movement of continental areas, the growth of mountain ranges and volcanic activity of various kinds that produces dust and gases which may alter transparency and other characteristics of the Earth’s surface.

            Human existence and development has affected climate patterns on the earth in many ways. The transformation land surface of the planet was by deforestation, ploughing land reclamation, the construction of huge man-made lakes, reservoirs, and the conversion of large areas to a built-up environment and so on. The water and energy balancing have also significant elements led to climate change. These noticeable changes are so far local but likely to become regional and global during the next 200years.

            We must plan set off long-term actions which enables man to avoid the adverse consequences of climate changes. They will inevitably occur in the future. He believes that it is possible with the international co-operation to access global problems and calls for ‘Change for the Better’.
