Hello, Dear Visitor. How are You? I hope you all are well. Today we will read about “Speech On Global Warming“. It is an essential Speech For Everyone. Welcome To MyArfan.com Let’s start.
Speech On Global Warming
Global Warming is when the Earth heats up (the temperature rises). It happens when greenhouse gases (carbon dioxide, water vapour, nitrous oxide, and methane) trap heat and light from the Sun in the Earth’s atmosphere, which increases the temperature. This hurts many people, animals, and plants. Many cannot take the change, so they die.
Many reasons may be there for Global Warming; the Primary and foremost cause is considered to be the Green House Effect. This effect is mainly caused by Carbon Dioxide, Methane, Chlorofluoro Carbon, Nitrous oxides etc. gases. These gases form a cover in the atmosphere around the Earth through which hot rays of the Sun can enter the Earth but cannot exit. So, the heat of the Sun remains in the lower circle of the Earth, making the temperature rise.
It is feared that the world may experience a rise in temperature of about 4° to 5°C by 2050. The average temperature of the Earth has risen by about one °C in the last five centuries, and of this, half of the Warming is caused in Twentieth Century alone. Global Warming is increasing at an alarming rate.
Global Warming is affecting many parts of the world. Global Warming makes the sea rise, and when the sea rises, the water covers many low-land islands. This is a big problem for many of the plants, animals, and people on the islands.
Global Warming is doing many things to people as well as animals and plants. It is killing algae, but it is also destroying many huge forests. The pollution that causes global warming is linked to acid rain. Acid rain gradually destroys almost everything it touches. Global Warming is also causing many more fires that wipe out whole forests. This happens because global Warming can make the Earth very hot. In woods, some plants and trees’ leaves can be so dry that they catch on fire.
Due to the rise in the average temperature of the Earth, agricultural crops, forests and life growth are affected adversely. It also changes the balanced equations of marine life. Melting of glaciers will result in the rise of sea level posing a threat to the habitat of coastal areas.
Because of these dangerous effects of ‘Global Warming,’ at the international level, measures are taken in the form of conferences, agreements and research.

speech on global warming in 150 words
Good morning to all my respected teachers and dear friends on this significant occasion. I want to give a speech on global Warming, which is a most prominent environmental issue. Day by day, we are feeling substantial changes in the atmosphere and climate of the Earth.
The Earth’s 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, tsunamis, cyclones, storms, thunder, etc., are the result of global Warming. We are feeling a massive change in the season’s length. Like the winter season is getting short and the summer season is bringing 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; the spring season seems to occur earlier, and flowers bloom before time from a few decades. Colossal climate change is the indication for us indicating harmful effects of global Warming. Birds are migrating from hotter to colder regions, and hurricanes in the Atlantic are more frequent and have high intensity. Sea levels are rising continuously; glaciers are melting because of stronger heat waves; 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 by 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, trap the dangerous UV rays and make the environment hotter. Because of global warming, drought and flood may occur more frequently. Increased Earth’s temperature worldwide causes more moisture absorption and, thus, droughts. Due to the lack, 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 does not been fulfilled due to drought. Thus, global Warming brings food shortages all over the world.
Warmer air in the atmosphere holds lots of moisture than cool air, which results in floods in many areas. Both droughts and floods adversely affect crop production. These are natural disasters affecting humans, animals and plants’ lives in many aspects. Coral reefs are considered to be the most important for the water’s lives as they provide food and shelter to fish, crabs, sea turtles, and other aquatic animals. So, global Warming is a significant threat to the existence of life here on the Earth in future. It needs to be solved by the worldwide effort of people on an urgent basis to maintain healthy and happy life here.
I hope you all understand the Speech. If You need any help, you can comment to us. There is no problem. Have a nice Day!
