Global Warming | Green House Effect

global warming

Global warming is a gradual increase in the temperature of the earth’s surface and atmosphere all around the world. There are many reasons behind this increasing global warming. It is a man who created environmental issues which are gradually affecting the whole environment all over the world for many years. 

Green House Effect:

A greenhouse is normally something useful. The greenhouse effect is defined as when the Earth’s atmosphere becomes thick with gases and substances which trap the sun’s radiation, making the Earth warmer. An example of a Greenhouse effect is global warming.

How Global warming occurs?

Let’s take an example:

  • We control our body temperature by dressing heavily when it is cold and dressing lightly when it is hot.
    If we wear a coat on a warm spring day that will make anyone feel hot.
  • In the same way, the earth has its own clothes to control its temperature.
    This function is fulfilled by the atmosphere, invisible to us, that wraps around the earth.
  • As we burn fossil fuels like coal, oil, and natural gas for energy or cut down and burn forests to create pastures and plantations, carbon accumulates and overloads our atmosphere. Global warming can only occur when the amount of heat in the Earth’s system changes by either being added or released.
  • When we release carbon dioxide it is like putting more clothes on the earth, leading to increased temperatures in the air from the ground surface up to an altitude of almost 20 kilometers.
  • The carbon dioxide we discharge in the process of living our lives also becomes a constituent in the atmosphere.
  • Carbon dioxide is causing all the fuss now, but there are many other gases that also cause warming.
  • Other gases discharged through human activities such as methane gas, and chlorofluorocarbons, made famous by the ozone hole, are not thought to have as big an impact on global warming as carbon dioxide, but in the same amounts they cause more temperature rise than carbon dioxide, so concerns about them are rising.

Effects of Global warming:

Increase in Temperature:

One of the most immediate and obvious effects of global warming is the increase in temperatures around the world. For most places, global warming will result in more frequent hot days and fewer cool days, with the greatest warming occurring over land.

The average global temperature has increased by about 1.4 degrees Fahrenheit (0.8 degrees Celsius) over the past 100 years. The hottest year on record worldwide was 2016, according to NOAA and NASA data. That year Earth’s surface temperature was 1.78 degrees F (0.99 degrees C) warmer than the average across the entire 20th century.

Changing Weather:

The planet is warming; extreme weather is another effect of global warming. While experiencing some of the hottest summers on record. Global warming may also lead to extreme weather other than cold or heat extremes. For example, hurricane formations will change. This is because hurricanes get their energy from the temperature difference between the warm tropical ocean and the cold upper atmosphere. Global warming increases that temperature difference.

Melting of Ice:

The melting of glaciers will create a maximum of problems for humankind and the animals living on the earth. Due to increased global warming, the level of the sea will rise which lead to flooding, and this will, in turn, create destruction in human life.

Rising Sea Levels:

Rising sea levels will gradually destroy coasts and cause more frequent coastal flooding. Some island nations will disappear. The problem is serious because up to 10 percent of the world’s population lives in unsafe areas less than 10 meters (about 30 feet) above sea level.


Global warming can affect agriculture. As the global temperature will increases, plants will find it harder to survive and will die. Plants are the major source of food for human beings and as a result, food shortages may occur. The shortage of food may lead to war and conflicts in some countries.

Health Risks:

As more carbon dioxide is trapped in the atmosphere, the breathable air becomes harder to come by. If global warming continues, the U.S. is looking at 60 billion dollars to combat respiratory diseases and symptoms. A study found that environmental pollution already causes more deaths than smoking. It kills an average of 8.8 million people around the world per year and also decreases people’s lives by two years. 

Some common daily life practices can reduce global warming

  • Reduce, Reuse, Recycle
  • Use less heat and air conditioning
  • Replace regular light bulbs with LED bulbs
  • Drive less and drive smart
  • Buy Energy-Efficient Products
  • Use less hot water
  • Use OFF switch, Save electricity
  • Plant a tree
  • Encourage others to conserve
