Global Warming Essay in English 500 words
Global warming is the increase in the earth’s average temperature observed since the pre-industrial period due to the release of several greenhouse gases to the atmosphere by human activities that include burning fossil fuels and various agricultural and industrial activities, which increases the levels of heat-trapping greenhouse gases in Earth’s atmosphere. Scientists explain the phenomena of the greenhouse effect as the release of gases that prevent the dissipation of ground heat into space causing global warming.
The gases primarily responsible for global warming include carbon dioxide, chlorofluorocarbons (CFCs), water vapor, nitrous oxide, and methane. In simple words, we can say that Global warming is the phenomenon of a gradual increase in the temperature near the earth’s surface. We often use the term “global warming” and “climate change” interchangeably.
Both the natural events and human influences are contributing to the rise in average temperatures. Apart from evolution of the greenhouse gases, a volcanic eruption is also a major natural cause of climate change. Humans aggravate the problem by farming livestock and cutting down trees that absorb these gases. Industries and vehicles such as cars, buses, trucks burn fuel releasing carbon dioxide and carbon monoxide from the exhaust, which causes the temperature of Earth’s atmosphere to rise. Another culprit is mining which releases the methane gas trapped below the earth. Also, rearing cattle contribute to this by releasing methane gas from manure.
There are several ill-effects of this climate change on earth and mankind. The increased atmospheric heat will likely increase the frequency and intensity of extreme events (such as floods, droughts, extreme rainfalls, heatwaves, storms, etc.) that threaten human health and life. The other concerns are reduced agricultural yields, declining water supplies, and erosion in coastal areas.
Due to global warming, the glaciers are melting which is causing the sea level to rise which is a threat to the low-lying areas and some of the continents may submerge and disappear from the world’s map in the future if this continues. Today, the worst affected countries by global warming are Japan, the Philippines, and Germany. According to a report China is the world’s largest contributing country to CO2 emissions, followed by the United States and India.
Several countries are joining hands together to combat the problem of climate change and many agreements have been signed from time to time, but still, the efforts are not adequate and scientists and environmentalists are warning of the disastrous consequences if these pacts are not fully implemented. A few small steps taken by each individual can make a lot of difference.
These include using CFL bulbs, buying energy-efficient appliances, using solar energy devices, conserving water and electricity, planting trees, etc. We also need to stop open burning dry leaves or burning garbage. It is high time that we humans together with the government should take effective measures to stop global warming. Our generation needs to take steps to protect the earth with immediate effect so that future generations shall not suffer the consequences of global warming.

Global warming is a major issue that our planet is facing right now, it is the gradual increase in the Earth’s overall atmospheric temperature. It is a grave problem that needs undivided attention. It is rising at an accelerating rate from the past century. This issue needs to be addressed with all our power because it can lead to massive environmental alterations.
We have already started observing frequent droughts, heat waves, storms, shifts in rainfall patterns, increasing sea levels which will lead to loss of coastal areas and disruption of saline water composition.These changes have gradually started destroying the ecosystems we live in and damaging the flora and fauna of various regions.
The major causes of global warming are increased concentration of greenhouse gases in the atmosphere, mainly from human activities such as burning fossil fuels, deforestation, farming livestock etc. Greenhouse gases trap the sun’s radiation, which would have otherwise bounced off the Earth, and radiate it back toward the planet. Due to some of these human activities there is an enormous release of greenhouse gases such as carbon dioxide, methane, nitrous oxide, water vapour, and synthetic fluorinated gases.

The effects of global warming are fatal for mankind. It’s not too late to stop global warming. We need to make changes both in the tiniest to the biggest parts of our lifestyle. Changes can start from reducing usage of fossil fuels. This could be done by switching to the use of renewable resources from non-renewable resources and also increasing the use of public transportation over personal transportation and also encouraging the concept of carpool.Planting more trees, it is the most cost- efficient way to tackle global warming.
Trees absorb carbon dioxide from the atmosphere. In fact, we could remove roughly two-thirds of man made carbon just by replantation and reforestation, according to a study published in the journal of Science. Using products that are recyclable can contribute a lot in lowering global warming. When we switch to recyclable products we are reducing the exploitation of more resources like trees,water etc which looks like a very small adjustment but makes a huge difference.
The present generation must take up the responsibility of stopping global warming in order to prevent the suffering of future generations. Therefore, every little step, no matter how small, carries a lot of weight and is quite significant in stopping global warming. We need support from each and everyone for making global warming stop. We need to create as much awareness as possible in order to incorporate everyone in the mission to save our planet.

Essay on Global Warming in English
Global warming is a climatic phenomenon and has severe impacts on climate as it increases the earth’s temperature and due to this various climatic changes occur on earth. It critically affects the life of humans and other living organisms. The impacts of global warming are life changing .
The glaciers are melting and avalanches are occurring more often. This also brings various disasters which cause many problems and people become homeless, deprived of food and many lost during the disaster. Due to the increase in the temperate many animals and species are unable to adapt and survive so become extinct .
This also disturbs the life cycle and food chain. This is a global problem and it becomes more severe if we don’t take care of it and take important steps. There is a great need to bring the attention of people towards this issue.
Global warming is a threat to all life forms sustaining on earth. This is caused by several things which can be divided into two categories – by human activities and natural causes.
Humans are evolving and their needs are also increasing. For fulfilling their own needs and facilities they are destroying the environment and resources. The modern lifestyle of people seeks comfort and luxury. Industrialization and urbanization are those which consume the most of resources and increase the temperature of the earth.
The man- made activities like burning of fossil fuels, mining of ores, and deforestation play a major role in global warming as trees and plants are cleared for land for industries and houses increase the temperature and reduce the rate of precipitation also the mining and burning of fossil fuels pollute the air and also deplete the ozone layer. Trees are very useful as they absorb the CO2 . The transportation vehicles used by humans like cars, buses, trucks use petrol and other fuels for engine consumption and release carbon dioxide gas which is a major global warming causing gas .
Chloro fluoro carbons , carbon dioxide gas, methane, nitrous oxide are primary greenhouse gases released by air conditioners, refrigerators, etc are primary greenhouse gases which absorb the radiant energy and increase the temperature of earth also the CFCs and other deplete the ozone which is harmful.
Natural causes of global warming is the release of greenhouse gases by natural disasters and activities like volcanic eruption. A single volcanic eruption releases tons of methane and carbon dioxide which absorb radiant energy from the sun . Methane is also released by cattle waste , petroleum pits, natural gas , landfills, etc.
Effects of global warming are alarming and dangerous for life on earth and it is also harmful for our mother earth. Due to increasing temperature the climatic conditions are changing due to which many species migrate from their habitat as they are unable to adapt to the change. The polar ice and glaciers are melting which increases the level of ocean water and sea level which causes floods, heavy rainfall and tsunami in those areas that destroys the vegetation, houses and the habitat of people .
The polar bear, Penguins, and many aquatic amphibians leave their habitat and many birds choose to migrate. These disasters also take the life of many . Many species become extinct and many are at the risk of being endangered if global warming continues to increase in future. Agriculture is also affected due to the changing climatic conditions which may cause decrease in production of food products and drought problems due to which people may die because of hunger.
Global warming is a big issue but can be solved with collective efforts and supporting each other. Individuals and governments both have to work together to fight this environmental evil. We should minimise the use of the resources and stop over using them . We should use public transport in place of individual vehicles and also replace the fuels like petrol and diesel with CNG and electric vehicles so that they don’t release harmful greenhouse gases.
Fossil fuels should be burnt in a limited ratio. Afforestation should be done in most of the places. Even the government must put limitations on the industries to emit less wastes and restrict them to definite areas . Strict rules and regulations should be issued by the government against the law violators so that we can save our mother earth from these threats and make a better and healthy environment for living.
