Climate change is real. It is happening right now, it is the most urgent threat facing our entire species and we need to work collectively together and stop procrastinating.
Climate change refers to the change in the environmental conditions of the earth. This happens due to many internal and external factors. The climatic change has become a global concern over the last few decades. Besides, these climatic changes affect life on the earth in various ways. These climatic changes are having various impacts on the ecosystem and ecology. Due to these changes, a number of species of plants and animals have gone extinct.
It is now widely accepted that human activity is also affecting climate, and that the impact is not the same everywhere. The sea affects the climate of a place. Coastal areas are cooler and wetter than inland areas. Clouds form when warm air from inland areas meets cool air from the sea. The centre of continents are subject to a large range of temperatures. In the summer, temperatures can be very hot and dry as moisture from the sea evaporates before it reaches the centre of the land mass. Ocean currents can increase or reduce temperatures. Winds that blow from the sea often bring rain to the coast and dry weather to inland areas. Winds that blow to Britain from warm inland areas such as Africa will be warm and dry. Winds that blow to Britain from inland areas such as central Europe will be cold and dry in winter. The distance from the equator affects the climate of a place. At the poles, energy from the sun reaches the Earth’s surface at lower angles and passes through a thicker layer of atmosphere than at the equator. This means the climate is cooler further from the Equator. The poles also experience the greatest difference between summer and winter day lengths: in the summer there is a period when the sun does not set at the poles; conversely the poles also experience a period of total darkness during winter. In contrast, daylength varies little at the equator. However, we cannot forget the influence of humans on our climate. Early on in human history our effect on the climate would have been quite small. However, as populations increased and trees were cut down in large numbers, so our influence on the climate increased. Trees take in carbon dioxide and produce oxygen. A reduction in trees will therefore have increased the amount of carbon dioxide in the atmosphere. The Industrial Revolution, starting at the end of the 19th Century, has had a huge effect on climate. The invention of the motor engine and the increased burning of fossil fuels have increased the amount of carbon dioxide (a greenhouse gas – more on that later) in the atmosphere. The number of trees being cut down has also increased, reducing the amount of carbon dioxide that is taken up by forests.
People may use compact fluorescent light (CFL) bulbs in spite of using regular incandescent light bulb as they consume 70% less energy than ordinary bulbs and have a longer life p. Reduce, reuse, and recycle policy should be adopted to control the pollution. People have to learn using eco-friendly products more and more and should adapt natural way of living. Reuse and recycle methods can significantly decrease the rate of change of the climate. Keeping in mind the apprehensions that scientists and environmentalists have expressed in front of us, it is in the interest of mankind to take precautions in time. Now the time has come for us to limit our needs and avoid being too materialistic. Environmentally friendly technological development, bio-fertilizers, use of bio-pesticides and bio-fuels are preferred, if necessary, cut trees and replace them with at least five trees, stop the destruction of forests, only then human can imagine society and manage to mitigate the effects of this problem to some extent. This will be a huge achievement in this direction. Otherwise it will not be easy to stop the destruction.
