Climate change refers to an increase in average global temperatures of the earth’s atmosphere. Both Natural calamities and the human activities as well are believed to be the equal contributors for such an increase in such global temperatures of the planet thus causing climate change.
When talking about natural calamities, there are a number of factors responsible for causing greenhouse effect on the earth. Some of them are like continental drifts, volcanoes, ocean currents, the earth’s tilt, and comets/meteorites. Due to the changes in them or in their position the earth’s atmosphere is very much affected. Certainly, when thinking of human activities the effect is much higher than the natural cause.
The Industrial Revolution in the 19th century has given rise to the use of fossil fuels and other toxic materials for industrial activities. Such substances when used in machineries and manufacturing process discharge high amount of waste gases and materials out. Nevertheless, all these waste materials are either exposed out into the air or the materials are drained out in the water bodies thus polluting the air and water respectively. Due to this ecosystem gets very much affected and so thus the earth’s atmosphere. This is the top most reason for the climate change today. However this alone is not responsible for such change. Urbanization also plays a major part in this as more and more land that was earlier covered with vegetation (flora) has been wiped out to make way for houses, offices and industries. Natural resources are also being used extensively for construction, industries, transport, and consumption and are many are reaching an extinction level.
In this glossary of researchers and scientists, climate modification as a term is no longer in use and effect. The reason behind this is that we have come to understand the effect of the changes we make to our environment eventually raise the temperature in many parts of the world, but it will also decrease the temperature of some parts of the planet. This, however, creates an imbalance in the general climate in the world.
While learning more about this global climate change, we must understand this important fact related to it. The fact that, it is a natural phenomenon and a reaction catalyzed by us. For example, greenhouse gases are a natural part of the biosphere and that if man does not exist. In fact, these gases are a vital component of the existence of life on this planet. They increase the temperatures to degrees favourable for life and prevent it from stagnating at a constant 0 degrees. However, increasing thiese gases causes too high temperatures.
