Global Warming Speech: The most talked about topic in the year 2020 is probably the issue of global warming. In this year alone, we have seen the pandemic, storms, floods, earthquakes and many other natural calamities that have gripped the world with experts suggesting that these are the consequences of global warming that we have been responsible for the last 50 years.
In this global warming speech, I shall be talking about the impact of global warming and how global warming is being escalated due to industrialisation and economic greed of countries.

Long Speech on Global Warming 600 Words
Global warming is an international phenomenon where the earth’s mean surface temperature is increasing rapidly due to the accumulation of greenhouse gases in the atmosphere. The source of these greenhouse gases is various, both natural and manmade, such as forest fires, industrialisation, burning of agricultural crops, burning of fossil fuels etc. Global warming has proved to be a huge force created by man that can have the potential to destroy the natural cycle of our planet.
Global warming is not a recent phenomenon but it has surely improved and increased because of rapid industrialisation, population explosion, agricultural explosion and the ever-increasing greed for economic growth for countries at the cos of of exploiting our environment. Global warming did exist hundreds of years before when civilizations begin to occur. There are examples of burning fossil fuels and causing pollution even during early civilizations like the Indus valley civilisation or Harappan civilization, but the magnitude of global warming today is thousand times more than what it was a few centuries back.
Some of the main greenhouse gases that are causing global warming are carbon dioxide, methane, nitrous oxide, sulphur hexafluoride, hydrofluorocarbons and perfluorocarbons. Most of the greenhouse gases are produced due to the consumption of fossil fuels.
The effects of global warming are plenty and one of the most catastrophic effects of global warming is the deterioration of the ozone layer. Due to the accumulation of chlorofluorocarbons in the stratosphere, scientists have predicted that an area above the continent of Antarctica has a huge ozone hole. The ozone layer is a layer in the atmosphere which protects the Earth’s surface from the harmful ultraviolet radiations coming from the sun. When this ozone layer gets depleted, the living beings on the planet earth is easily exposed to UV rays. This can cause catastrophic effects on human health, agricultural cycle, climatic cycle and on the very existence of our planet.
Let me mention a few of the impacts of global warming that we are already seeing in the year 2020. It is due to global warming that there is a rise in sea levels which is causing flooding off patches of lands, the low lying setters and islands countries of Indonesia and Japan. Global warming is causing changes in the rainfall patterns. When the change in rainfall patterns and climatic changes occurs abruptly, it becomes difficult for the Meteorological Departments to predict natural calamities and this increases the damage caused to life and property.
Draughts, forest fires floods and earthquakes are some of the indications for changing in climatic patterns caused due to global warming. Melting of glaciers and polar ice caps has caused almost extinction of habitat near the north pole and the south pole. The polar bears, which are considered to be greatly endangered species, are decreasing in their population by the day because of the melting of glaciers. Melting of glaciers can also lead to an increase in floods and famine in the nearby regions.
Certain diseases like Malaria are caused due to global warming since there is the migration of species from one place to another. Many scientists also predict that the COVID-19 pandemic that we are witnessing in the year 2020 can also be traced back to the impact of global warming when seen from the bird’s point of you.
I would like to conclude my global warming speech by saying that the international community, governments and citizens has to come forward to reduce your carbon footprint to save the planet for our future generation. All of us living here are the stakeholders of nature and we are responsible for how we take care of our environment. As the saying goes, charity begins at home, we have to start using biodegradable materials at our houses, reduce plastic waste and other such changes in our lifestyle so that we can make an impact to reduce global warming globally.
Short Speech on Global Warming 200 Words
Global warming is defined as the process of increasing the average temperature of the earth’s climatic system due to the increased accumulation of greenhouse gases in the atmosphere. The consequences of global warming around the world are already being seen in the year 2020 with the rising sea levels, forest fires, earthquakes floods and other such natural occurrences. Global warming not only has an impact on nature but also has an impact on all the living beings including human beings on the planet. Global warming will affect the agricultural cycle and make predictions of climatic conditions even more difficult for scientists and engineers which in turn increases the damage caused due to natural calamities on life and property.
Some of the main reasons for global warming is the burning of fossil fuels that release harmful greenhouse gases such as carbon dioxide or nitrogen. Water vapour, carbon dioxide and Methane are some of the most harmful greenhouse gases that are accumulating at an increasing rate in the earth’s atmosphere. These greenhouse gases are depleting the ozone layer that protects the surface of the earth from the harmful ultraviolet radiation coming from the Sun.
I will Conclude my short global warming speech by saying that the international community has to come forward to find a long-lasting solution to global warming. If not, then the average temperature keeps increasing and that in turn affects the natural cycle and the basic structure of the ecosystem and the world as we know it will be changed forever.
10 Lines On Global Warming Speech in English
- Global warming is defined as the increase in the average temperature of the Earth due to the accumulation of greenhouse gases in the atmosphere
- The most harmful greenhouse gases in the atmosphere are water vapour, carbon dioxide, methane, nitrous oxide, ozone, chlorofluorocarbons and hydrofluorocarbons
- Effect of global warming and greenhouse effect is seen in the rising sea levels that can in turn cause floods and harm the aquatic life
- The major source of carbon dioxide is the burning of fossil fuels that are used in vehicles, industries and many electronic devices in our households
- The international treaty that commits all the countries to reduce the emission of greenhouse gases is known as the Kyoto Protocol
- Kyoto Protocol set limits to industrialisation and other practices that are causing global warming at an alarming rate on our planet
- The effects of global warming are changes in the agricultural cycle, melting of polar ice caps, floods and changes in the natural climatic system of the planet
- The impact of greenhouse gases is seen in soil degradation and desertification of the arid areas on the planet
- The rise in the average temperature of the earth results in absorption of heat and other greenhouse gases by water bodies and thereby reducing its oxygen content which affects the aquatic life in our water bodies
- Use of green energy such as nuclear energy or wind energy or solar energy is one of the solutions to reduce the emission of greenhouse gases into the atmosphere
