Paragraph on Global Warming

Global Warming means the rise in the average surface temperature of the earth due to the greenhouse effect. It is caused due to human activities like industrialization, deforestation, and the use of fossil fuels. It is a serious threat to the environment and habitat on the planet.

Short and Long Paragraphs on Global Warming

Paragraph 1 - 100 Words

Global Warming refers to the warming of the earth, that is, an increase in the surface temperature of the earth. This temperature increase is caused by a number of human activities like industrial emissions and fossil fuel burning. These activities generate gases which cause the greenhouse effect and consequently global warming.

Global warming raises the average surface temperature of the earth, causing many undesirable effects. Some of the most significant effects of global warming are climate changes, famine, droughts, species depletion, etc. The temperature of the earth is steadily rising every year at a constant rate. Global warming is the most immediate threat to the earth and the life that it supports.

Paragraph 2 - 120 Words

Every year the average surface temperature of the earth gets more than the previous year. Every year it gets warmer than the previous year. Since 1880 the average surface temperature of earth has increased by about 0.8°Celsius.

The rate of warming has been around 0.15°-0.2°Celsius per decade. This is a global change in the earth’s temperature and must not be confused with local changes that we experience every day, during day and night, summer and winter, etc.

The global average temperature of the earth mainly depends on the amount of heat it receives from the sun and what it radiates back into the atmosphere. The heat radiated back by the earth depends on the chemical composition of the atmosphere.

Paragraph 3 - 150 Words

Global warming is a phenomenon when the average surface temperature of the earth rises beyond the suitable limit. The phenomenon behind global warming is the greenhouse effect.

The greenhouse effect occurs when the greenhouse gases in the atmosphere prevent the escape of heat radiated from the surface of the earth. This, in turn, traps the heat into the atmosphere and increases the temperature causing global warming. Global warming has many severe consequences on the environment.

When humans burn fossil fuel; gases like Carbon dioxide (CO2), methane (CH4) and Ozone (O3) are emitted into the atmosphere. These gases form a blanket of sorts over the earth, preventing the heat from dissipating into the atmosphere.

This is called the greenhouse effect. The greenhouse effect, in turn, increases the earth’s temperature and this increase in temperature is termed as global warming.  Global warming causes the surface temperature of oceans to rise and other extreme climatic conditions.

Paragraph 4 - 200 Words

Global warming is the process of a slow yet steady increase in the earth’s surface temperature. This temperature increase is caused due to the greenhouse effect. The greenhouse effect is caused due to emission of gases like carbon dioxide and ozone, etc. Global warming has made some serious climatic changes on the planet.

Still, there is a constant rise in the earth’s average surface temperature recorded every year. If the temperature continues to rise like this then within a couple of decades, the earth will become too hot to sustain life. Also, there will be widespread famine, droughts, floods, and other natural disasters.

Even a single degree rise in temperature is enough to spell disaster for the earth and its inhabitants. The factors responsible for global warming are man-made. Burning of fossil fuel in automobiles and for other purposes releases gases like carbon dioxide (CO2), which is a greenhouse gas. Deforestation and emissions from factories also cause a greenhouse effect and global warming.

There are also some natural causes of global warming like volcanoes, water vapor, and forest fire. Volcano eruption contains a large amount of ash and dense smoke which impacts the temperature.  Forest fires emit smoke rich in carbon, thereby causing a greenhouse effect.

Paragraph 5 - 250 Words

Global warming means a rise in surface temperature of the earth. This rise in temperature is mainly caused due to the greenhouse effect. It is an effect where the heat is trapped into the earth’s surface. Gases like carbon dioxide (CO2) and Ozone (O3) prevent the heat from escaping and therefore called greenhouse gases. Activities like fossil fuel burning and production produce greenhouse gases as byproducts. When the concentration of these gases increases in the atmosphere, they cause more and more greenhouse effect.

Thus, the temperature of the earth rises continuously. This continuous rise in temperature is called global warming and is responsible for many significant changes in climate and biodiversity. The effects of global warming have been very clear in some places on the globe.

There have been incidents of extreme drought due to global warming. Regions, where rainfalls used to be plenty, are experiencing lesser rainfall. There has been a shift in the monsoon pattern over the globe. Global warming also causes the melting of glaciers and an increase in the ocean level, resulting in floods.

Global warming also affects the species widely. Some land species are very sensitive to temperature and climatic changes and can’t survive extreme conditions. For example, Koalas are at risk of starvation due to climate changes. Several species of fishes and tortoises are sensitive to temperature changes in the ocean and die.

Coral reefs are also extremely sensitive to changes in temperature and their numbers are declining. Global warming is a serious problem and must be dealt with with full effort and seriousness.
