Global Warming Definition

“Global warming is a gradual increase in the earth’s temperature generally due to the greenhouse effect caused by increased levels of carbon dioxide, CFCs, and other pollutants. “


 

Global warming is the phenomenon of a gradual increase in the temperature near the Earth’s surface. This phenomenon has been observed over the past one or two centuries. This change has disturbed the climatic pattern of the earth. However, the concept of global warming is quite controversial but the scientists have provided relevant data in support of the fact that the temperature of the Earth is rising constantly.

There are several causes of global warming, which have a negative effect on humans, plants and animals. These causes may be natural or might be the outcome of human activities. In order to curb the issues, it is very important to understand the negative impacts of global warming.

Let us have a detailed study of global warming, its causes, and its effects.

 

Man-made Causes of Global Warming

 

Deforestation one of causes global warming because plants are the main source of oxygen. They take in carbon dioxide and release oxygen thereby maintaining environmental balance. The forests are being depleted for many domestic and commercial purposes. This has led to an environmental imbalance, thereby giving rise to global warming.thenThe use of vehicles even for a very short distance results into various gaseous emissions. Vehicles burn fossil fuels which emit a large amount of carbon dioxide and other toxins into the atmosphere resulting in a temperature increase.With the excessive use of air conditioners and refrigerators, humans have been adding CFCs into the environment which affects the atmospheric ozone layer. The ozone layer protects the earth surface from the harmful ultraviolet rays emitted by the sun. The CFCs has led to ozone layer depletion making way for the ultraviolet rays, thereby increasing the temperature of the earth.then,Industrial Development one of causes oglobal warming.With the advent of industrialization, the temperature of the earth has been increasing rapidly. The harmful emissions from the factories add to the increasing temperature of the earth.
 
 In 2013, the Intergovernmental Panel for Climate Change reported that the increase in the global temperature between 1880 and 2012 has been 0.9 degrees Celsius. The increase is 1.1 degrees Celsius when compared to the pre-industrial mean temperature.
 
 Increase in population means more people breathing. This leads to an increase in the level of carbon dioxide, the primary gas causing global warming, in the atmosphere.
 
 

Natural Causes of Global Warming

Volcanoes are one of the largest natural contributors to global warming. The ash and smoke emitted during volcanic eruptions goes out into the atmosphere and affects the climate.besides,Water vapour is a kind of greenhouse gas. Due to the increase in earth’s temperature more water gets evaporated from the water bodies and stays in the atmosphere adding to global warming.


Effects of Global Warming

Following are the major effects of global warming:

 Global warming has led to an incredible increase in earth’s temperature. Since 1880, the earth’s temperature has increased by ~1 degrees. This has resulted in an increase in the melting of glaciers, which have led to an increase in the sea level. This could have devastating effects on coastal regions.

 global warming has affected coral reefs that could result in the loss of plant and animal life. Rising global temperatures are making coral reef fragility worse. Global warming is also leading to changes in heat and humidity patterns. This causes the movement of mosquitoes that carry and spread the disease. Meanwhile, global warming has also caused climate change. There are droughts in some places and floods in some places. This climate imbalance is the result of global warming. 

 Due to an increase in floods, tsunamis and other natural calamities, the average death toll usually increases. Also, such events can bring about the spread of diseases that can hamper human life.A global shift in the climate leads to the loss of habitats of several plants and animals. In this case, the animals need to migrate from their natural habitat and many of them even become extinct. This is yet another major impact of global warming on biodiversity.

Mental Health

  The relationship between resilience and mental health Having solid mental health doesn’t mean that you never go through bad times or experience emotional problems. We all go through disappointments, loss, and change. And while these are normal parts of life, they can still cause sadness, anxiety, and stress. But just as physically healthy people are better able to bounce back from illness or injury, people with strong mental health are better able to bounce back from adversity, trauma, and stress. This ability is called  resilience . People who are emotionally and mentally resilient have the tools for coping with difficult situations and maintaining a positive outlook. They remain focused, flexible, and productive, in bad times as well as good.  Their resilience  also makes them less afraid of new experiences or an uncertain future. Even when they don’t immediately know how a problem will get resolved, they are hopeful that a solution will eventually be found.

MENTAL ILLNESS BY HAIQAL

  The World Health Organization (WHO) reported that of all illnesses, depression is the leading cause of ill health and disability worldwide. According to the latest estimates from WHO, more than 300 million people are now living with depression. Depression and anxiety are prevalent problems in colleges across the country. During college, students experience many firsts, including a new lifestyle, friends, roommates, exposure to a new culture and experiences. Students may struggle if they can't manage these firsts. If students aren't prepared to cope, they can become easily susceptible to depression and anxiety.    Depression is a medical condition that can affect a student's ability to work, study, interact with peers, or take care of themselves. Symptoms of depression may include: difficulty sleeping or sleeping too much, appetite changes, withdrawing from participating in activities once enjoyed, feelings of sadness, hopelessness, unhappiness, and difficulty concentr...
