Long and Short Speech on Global Warming

Speech 1

Good morning to my respected teachers and dear friends. I would like to speech on Global Warming at this occasion. Global warming is a continuously increasing environmental issue all over the world. There is no single country responsible for its causes, all the countries worldwide are responsible for its ever-increasing.

Actually global warming is a global increase in the temperature of the earth because of our daily activities. Our various activities heat up the earth which ultimately rises its temperature. A rise in temperature takes place when greenhouse gases (such a carbon dioxide, water vapours, nitrous oxide, methane, etc) trap heat and light from our surroundings and sun.

Ultimately, a rise in temperature hurts the lives of human beings, animals, and plants. There are many reasons for the increasing global warming however some of the primary and main causes are considered because of the Green House Effect.

The greenhouse effect is caused by the greenhouse gases carbon dioxide, chloro-fluoro carbon, methane, nitrous oxides, etc gases. Such greenhouses gases are generated by our daily activities and get collected into the atmosphere and form a cover around the Earth which again absorbs hot sun rays and makes this earth burning earth. The absorbed heat remains in the lower circle of the biosphere and enhances the temperature level. According to the statistics it has been estimated that by 2050 the rise in temperature of the earth would be about 4° to 5°C. In the last five centuries, it has raised by about 1°C however half of this warming is raised only during the twentieth century. So, global warming is at peak and alarms us regularly with its bad effects.

It is affecting almost all parts of the world and causing sea level to rise, glaciers to melt and many more which covers all the low land islands. It is destroying huge forests, killing algae, acid rain, etc. Acid rain is very dangerous which may destroy anything in touch. Global warming causes natural fires that may wipe out whole forests. Continuous rise in the earth’s temperature affects agricultural crops, forests, marine life and life growth on the earth. It cannot be solved by the effort of only one country, it needs the global effort of all countries to reduces its effects and completely eliminate it.

Thank You

Speech 2

Good morning to my respected teachers and my dear friends. Nowadays, every one of us is well aware of the threat of climate change. It is a serious issue increasing continuously because of global warming. It is a big issue for our future generations to face all the challenges of this irreversible catastrophe changes in the environment. Global warming is the regular increase in the atmospheric temperature of the earth. Earlier the rate of rising in temperature was slow however currently it is going at a faster rate. The main causes of global warming are greenhouse gases such as nitrous oxide, carbon dioxide, methane, etc. Such gases get collected in the atmosphere and trap heat from all resources like sun and heat created by human activities (burning fossil fuels, petroleum, deforestation, etc). Global warming affects our planet’s atmosphere in many ways.


Because of the increasing temperature in the environment, the arctic glaciers start melting and threatening the life of polar bears. Melting glaciers creates lots of water which increases sea levels in the low land areas of the South Sea Islands. Increasing ocean temperatures creates problems for the life of plants and animals of water causes algae to die and disturbs the entire food chain. In order to lessen the side effects of the global warming, many laws have been made and implemented by the government of various countries such as limiting the harmful vehicle emissions, reducing emissions of chemicals causing damage to the ozone layer, reducing plant cutting, inducing tree planting, carpooling, etc.

We should change our habits positively in order to reduce waste by choosing the use of reusable products instead of a disposable one. We should buy products having minimal packaging to reduce the number of wastes. We should recycle paper, newspaper, glasses, aluminium cans, etc. If we start recycling at least half of your household wastes, we can save approximately 2,400 pounds of carbon dioxide emission every year. We should reduce the need for electric use such as air-condition, hair drier, room heater, etc. We should make the habit of turn downlights while sleeping at night or day when we go outside. We should replace our regular bulbs with the compact fluorescent light (CFL) bulbs. Regular use of the CFL instead of regular light bulbs would help in eliminating around 90 billion pounds of greenhouse gases from the atmosphere.

We should try to drive less and in a very smart way for the fewer harmful gas emissions. We should try to walk on foot as much as possible instead of using a bike, car or other means of transport. We should reduce our hot water use and try to use cold water as much as possible. In this way, by reducing our electricity use we can reduce global warming. Together with changing our own habits, we should encourage others to conserve energy by reducing lights use as much as possible.

Thank You


Speech 3

Good morning to my respected teachers and my dear friends, I would like to speech on the topic of global warming today. Global warming is mainly caused by the increasing concentration of greenhouse gases in the earth’s atmosphere. Some of the greenhouse gases are CO2, water vapour, methane, nitrous oxide and ozone. When these gases get collected to the lower environment, it makes a cover which easily allows all the hot radiations of the sun to the earth, however, restrict its escape back to space. This process is called the Green House Effect. Such gases in the atmosphere trap hot radiations and keep the earth warm by increasing temperature.


The level of greenhouse gases also raises because of human activities such as burning trees, burning fissile fuels, electric lights, use of refrigerator, microwave, air conditioner, and other electric machines. Such a process releases a high percentage of carbon dioxide and other greenhouse gases into the atmosphere causing the earth temperature to rise. A rise in heat causes more water from the earth to evaporate into the atmosphere, water vapour again absorbs more heat and makes earth atmosphere warmer. Global warming has changed natural processes rainfall patterns, length of seasons, a rise of sea level, ecology balance and many more. It is a powerful demon affecting our lives to a great extent so it needs to be solved on an urgent basis by the effort of all of us.

Thank You


Speech 4

Good morning to all my respected teachers and dear friends on this great occasion. I would like to give a speech over the global warming which is the most prominent environmental issue. Day by day, we are feeling great changes in the atmosphere and climate of the earth. The earth atmosphere is getting warm gradually however the process has become fast in the last few years. The natural disasters we are facing now a day such as earthquakes, tsunami, cyclone, storm, thunder, etc are the result of global warming. We are feeling a huge change in the season’s length like winter season is getting short and the summer season is getting long. Polar icecaps and glaciers are melting to a great extent.

In some regions of the country, there is a decrease in the snowfall amounts; spring season seems to occur earlier and flowers bloom before time from few decades. Huge climate change is an indication for us indicating the bad effects of global warming. Birds are migrating from hotter to colder regions, hurricanes in the Atlantic are more frequent having high intensity. Sea levels are rising continuously, glaciers are melting because of stronger heatwaves, human health is getting deteriorated, the climate is changing, weather patterns are changing, environment temperature is increasing affecting the whole climate adversely, and other problems because of the human industrial activities.

Earth’s surface-atmosphere is steadily increasing because of the primary causes of global warming such as the greenhouse effect of greenhouse gases. Greenhouse gases collected in the atmosphere like carbon dioxide traps the dangerous UV rays and makes the environment hotter. Because of the global warming drought and flood may occur more frequently. Increased earth’s temperature worldwide causes more moisture absorption and thus droughts. Due to the drought fields do not get adequate soil moisture so the farmers face lots of financial hardship. The worldwide people’s demand for fruits, vegetables, and grains do not become fulfil due to drought. Thus, global warming brings food shortages all over the world.

Warmer air in the atmosphere holds lots of moisture than the cool air which results in the flood in many areas. Both droughts and floods adversely affect crop production. These are natural disasters affecting human, animals and plants lives in many aspects. Coral reefs are considered to be the most important for the water lives as they provide food and shelter to the fish, crabs, sea turtles, and other aquatic animals. So, global warming is a big threat to the existence of life here on the earth in future. It needs to be solved by the global effort of people on an urgent basis to maintain a healthy and happy life here.

Thank You
