‘Global warming’ is a phenomenon in which the average temperature of the Earth rises above an acceptable range. This is caused by another phenomenon known as the ‘greenhouse effect’. In the essay below, we will learn about the causes and effects of global warming in detail.

Global warming refers to an increase in the average surface temperature of the Earth resulting in unusual climatic conditions and other geographic changes. In the essay below we will discuss the effects of global warming.
Effects of global warming
Global warming has widespread and far-reaching effects on the environment, biosphere, and animals, plants, humans, etc. Given below are some important effects of global warming.
Increase in surface temperature
This is the most immediate effect of global warming. Since the last century, the average surface temperature of the Earth had increased by a record of 1.4 ° F or 0.8 ° C. On 2016, the Earth’s surface temperature was recorded as a year warming to 1.78 ° F or 0.99 ° C. This temperature rise was the highest recorded in the entire 20th century. Record-keeping of Earth’s surface temperature is maintained by the National Marine and Atmospheric Administration (NOAA) and the National Aeronautics and Space Administration (NASA). The rise in temperature is not consistent around the world, but varies from place to place.
Extreme climatic conditions
Global warming causes unpredictable and extreme climate change throughout the world. Many places face extreme cold and hot temperatures as never seen before. Some of the hottest temperatures in the US and Asia have been recorded to date. The season’s event has also seen a change, perhaps due to global warming. An increase in the Earth’s temperature interferes with the normal flow of winds in the oceans and the surface, resulting in unpredictable changes in the monsoon and other seasons.
Slowdown in snow cover
Global warming is slowly and steadily melting the Earth’s ice cover. In the last 50 years, the continents of North America and Asia have seen a significant decrease in snow cover. There is a significant decrease of frozen plains in the Northern Hemisphere by about 10%. Glaciers around the world are also melting due to global warming.
Sea level rise
The main reason for the rise in sea level is the snow cover and melting of glaciers. According to data provided by the World Meteorological Organization, the level of the ocean is increasing by about 3 millimeters annually. If we look at the data of the last two centuries, we will find that the sea level has increased about 8 inches since then. Melting of Arctic ice, Antarctic ice and glaciers is the main cause of global warming. The number of glaciers found around the world has also decreased significantly.
Ocean acidification
Global warming is caused by the greenhouse effect and an increase in atmospheric levels of carbon dioxide (CO2). CO2 dissolves in sea water, causing acidification. Atmospheric CO2 dissolves in sea water, forming carbonic acid. Since the Industrial Revolution, atmospheric concentration of CO2 has increased, resulting in acidification of the oceans. Marine acidification leads to degradation of marine species. Most marine species have calcium shells. When the water becomes acidic, it starts dissolving the shells causing the species to shrink. Coral reefs, oysters, turtles are some aquatic species most affected by ocean acidification.
The conclusion
It is in all likelihood that humans are primarily responsible for global warming. The causes of global warming are anthropogenic and natural causes, which are ever negligible. Humans also have the responsibility to mitigate the effects of global warming. Stringent steps should be taken by the world community to reduce global warming and its harmful effects.

Global warming is caused by many human activities including industrialization, use of fossil fuels, deforestation etc. One main cause of global warming is the greenhouse effect. In the essay, we will briefly discuss the causes of global warming.
Causes of global warming
The following – burning of fossil fuels, deforestation and agricultural activities are the major causes of global warming as described below.
Burning fossil fuels
Greenhouse gases are produced by the production and use of fossil fuels by humans for various activities, resulting in global warming. Whenever fossil fuels are burned in the form of coal or petrol to power our plants or transport vehicles, a powerful greenhouse gas CO2 is released into the atmosphere. Almost all power generation plants use coal as the primary fuel, resulting in heavy production of CO2 gas. Even the production of fossil fuels results in the production of some powerful greenhouse gases that later lead to global warming.
Deforestation
Plants and trees are natural air filters and play an important role in cleaning the air. Trees have a natural process of absorbing CO2 and emitting oxygen. It is unnecessary to mention how important oxygen is for the survival of humans, animals and plants on the planet. Unfortunately, large forested areas are being cleared for commercial activities, resulting in large atmospheric concentration of CO2 and consequently increased global warming. The more forests that are cleared, the higher will be the concentration of CO2 and therefore the greater the global warming.
Agricultural activities
Agricultural activities are also responsible for global warming. Today the agricultural industry uses chemical fertilizers and disinfectants. Most of them produce harmful greenhouse gases upon decomposition. Nitrous oxide (N2O) is one of the powerful greenhouse gases generated due to the use of chemical fertilizers and disinfectants. Also, cattle such as cattle and others produce methane (CH4), another powerful greenhouse gas. With a large livestock population and a wide grazing area, the production of methane is sufficient to cause global warming.
The conclusion
Global warming is mainly due to human activities like industrialization, transportation etc. The key to reducing global warming and its effect lies in reducing the production of greenhouse gases. This can be achieved to some extent by enacting strict laws for industries and using alternative fuel sources instead of traditional fossil fuels.

Global warming refers to an increase in the average surface temperature of the Earth. It is caused by a phenomenon called the greenhouse effect. In the essay below we will discuss what is the greenhouse effect and hence global warming.
What is the global temperature?
Gases in the Earth’s atmosphere are a natural shield that prevents the heat of the sun from moving from the Earth’s surface to the outer atmosphere, therefore maintaining the surface temperature to a suitable level. Carbon dioxide (CO2), carbon monoxide (CO) and ozone (O3) are some of the main greenhouse gases.
Problems arise when human activities such as industrialization and transportation result in the production of greenhouse gases as a by-product, increasing their atmospheric concentration. The higher the concentration of greenhouse gases in the atmosphere, the higher the greenhouse effect, i.e. the more heat will be prevented from escaping into the atmosphere.
When the heat reflected from the Earth’s surface is not allowed to escape from the atmosphere, the surface temperature naturally increases. This phenomenon is called global warming, which is caused by the greenhouse effect, as noted above. Greenhouse gases form a type of blanket on the surface of the Earth, which conserves heat.
The conclusion
Global warming is an immediate threat to the environment and is a matter of grave concern. It is the right time for world powers to intervene and take necessary measures until it is too late. The world needs to join hands to fight global warming and its effects.
