essay on climate change 200 words
Answers
Answer:
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.
Explanation:
when did it start?
the climate started changing a long time ago due to human activities but we came to know about it in the last century. during the last century, we started noticing the climatic change and its effect on human life. we started researching on climate change and came to know that the earth temperature is rising due to a phenomenon called the greenhouse effect. the warming up of earth surface causes many ozone depletion, affect our agriculture, water supply, transportation, and several other problems.
reason of climate change
although there are hundreds of reason for the climatic change we are only going to discuss the natural and manmade (human) reasons.
get the huge list of more than 500 essay topics and ideas
natural reasons
these include volcanic eruption, solar radiation, tectonic plate movement, orbital variations. due to these activities, the geographical condition of an area become quite harmful for life to survive. also, these activities raise the temperature of the earth to a great extent causing an imbalance in nature.
human reasons
man due to his need and greed has done many activities that not only harm the environment but himself too. many plant and animal species go extinct due to human activity. human activities that harm the climate include deforestation, using fossil fuel, industrial waste, a different type of pollution and many more. all these things damage the climate and ecosystem very badly. and many species of animals and birds got extinct or on a verge of extinction due to hunting.
effects of climatic change
these climatic changes have a negative impact on the environment. the ocean level is rising, glaciers are melting, co2 in the air is increasing, forest and wildlife are declining, and water life is also getting disturbed due to climatic changes. apart from that, it is calculated that if this change keeps on going then many species of plants and animals will get extinct. and there will be a heavy loss to the environment.
what will be future?
if we do not do anything and things continue to go on like right now then a day in future will come when humans will become extinct from the surface of the earth. but instead of neglecting these problems we start acting on then we can save the earth and our future.
although humans mistake has caused great damage to the climate and ecosystem. but, it is not late to start again and try to undo what we have done until now to damage the environment. and if every human start contributing to the environment then we can be sure of our existence in the future.

Answer:
Climate change is regarded as a change in the climate pattern that is a result of internal and external forces. External forces can be defined as the change in the orbit of Earth, change in solar radiation, plate tectonics, volcanic eruptions, etc. It can also result due to human activities like carbon emission, greenhouse gases etc. Internal forces are defined as the natural procedures that happen within the entire climate system. All of these includes the variation in ocean- atmosphere variability and the existence of human life on the planet.
Climate change has a negative influence on the wildlife, forests, polar region and water systems on the planet. There are various species of animals and plants that have become extinct due to the variations in the Earth climate.
Human activities like deforestation that is performed for the use of land for commercial purposes results in an increase in the presence of carbon in the entire atmosphere. It has been seen as a major factor behind climate change. It is required to keep a track on all activities to control changes in climate and ensure harmony in environment.
Causes that leads to changes in climate
There are a few major factors that leads to changes in climate. These are as follows:
Solar Radiation
The energy that emits by the sun and reaches the Earth. This energy is carried to different areas of the planet via ocean currents and winds. It is seen to be one of the major reasons behind climate change.
Human Activities
Modern age technology has contributed towards emission of carbon content on the planet. This has resulted in an adverse impact on the climate. In addition to it, the plate tectonics, volcanic eruptions and orbital variations even bring modifications in the climate.
