What is Global Warming? Definition, Causes, and Effects

In the last 200 years, the world has seen a lot of changes in lifestyle. Human beings started living in luxurious houses, always lit up with not only necessary but also aesthetically pleasing lighting and all modern technology equipment for small things like brushing our teeth. The outskirts of cities also began to develop rapidly, with tall skyscrapers.

What is Global Warming?

Trading goods and traveling from one corner of the earth to another became a matter of a few hours. We’ve changed most of our metal or fabric requirements to some of the most important things like turning metal parts of airplanes into everyday things like water bottles and carry bags, which are now very widely used. Yes, that is ‘plastic’. The question ‘why?’ Because it is cheap, light and easily available.

We started diverting the natural flow of water by building dams and generating electricity so that we can operate our use as well as unnecessary electrical equipment easily. “Don’t feel like cooking today? Don’t worry, we’ll order some online or just have some ready-to-eat meals. Food is delivered within 30 minutes on bikes in plastic boxes and bags. So many big industries have been set up for the production of small things. Overall, we have seen a lot of development, but at the cost of our environment and all other living beings on earth. That’s how we humans have become ‘selfish’.

95% of plastic waste usually ends up in landfills and oceans, usually disguised as fish food, which causes death or ends up in our stomachs when we consume fish. We have become so dependent on automobiles while saving time but did not care to save our future and environment.

They cause a lot of air pollution and mining of fossil fuels which are going to be extinct in the near future. Our luxury homes and urbanization usually end in deforestation as we begin to perceive trees as a burden. All this causes a lot of problems, and one of the most dangerous effects is ‘global warming.

What is Global warming?

Global warming is the gradual increase in the temperature of the earth due to the increase in the greenhouse effect.

When the Sun’s energy reaches Earth’s atmosphere, most of the energy is not reflected back into space but is trapped in bubbles of greenhouse gases such as water vapor, carbon dioxide, methane, nitrous oxide, and synthetic chemicals such as chlorofluorocarbons. This absorbed energy helps life to exist by keeping the earth warm.

But this heat energy has increased a lot over the past 70 years because we produce too many greenhouse gases, and this is causing the Earth to warm more than usual.

Effects of Global warming

Rise in Air temperatures- 

The observed increase in temperature has occurred on all continents across the globe. 2016 was the hottest year in the world since 1880.

Ocean warming-

The heat content of the oceans has increased during recent decades.

Rising sea levels-

Ocean currents that play a major role in controlling the planet’s climate are also changing, particularly in the Southern Ocean. Studies have shown that the deepest ocean waters in the Antarctic, which are usually the coldest waters, have warmed and subsided.

Effects of Global warming

Ocean acidification-

About a quarter of the carbon dioxide produced by humans is absorbed by the oceans. As carbon dioxide dissolves in ocean water, it forms carbonic acid, making the ocean more acidic since the 1980s and already affecting marine organisms.

Extreme weather-

Extreme weather events include heatwaves, bushfires, tropical cyclones, cold snaps, extreme rainfall including flash floods, and drought.

Rainfall patterns-

Rain patterns are changing around the world. The global water cycle is accelerating with a warming climate, which means that wet areas are likely to become wetter and dry areas are likely to dry out in response to climate change.

Increased average number of hot days per year.

Decreased average number of cold days per year

What does climate change have to do with health?

Although climate change is not generally considered a clinical problem, it will affect all patients and communities. Patients are likely to feel the effects in their lifetime, and their children certainly will.

Chronic diseases: Increase in flood mortality among persons with chronic conditions like diabetes, hypertension, heart disease, etc.

Wildfires:  The drought has led to an increase in forest and bush fires.

Infectious disease:  After Hurricane Katrina, outbreaks and flooding such as norovirus increased the risk of waterborne infectious disease.

Social determinants of health: Jobs are lost, care for chronic medical conditions is disrupted, economic destruction, and health care systems are destroyed.

The increased global incidence of dengue fever: For example, dengue is spreading in the Florida Keys.

Spread of Arbovirus infections:  Like West Nile virus, Chikungunya virus.

Increased risk of cholera:  Moved on to temperature-sensitive marine copepods.

Increased risk of foodborne disease from food sitting out; Increase in the rate of pathogen growth.

Allergies:  Extended hay fever season and more severe allergic reactions.

Cardiovascular outcomes:  The risk of myocardial infarction is increased.

Mental health: higher rates of schizophrenia, anxiety, and depression; Children have an increased risk of learning difficulties and a decreased sense of well-being.

Perinatal outcomes:  Possible links to higher rates of miscarriage, premature labor, and low birth weight babies.

Respiratory outcomes:  Increased risk of respiratory diseases such as asthma, community-acquired pneumonia, lung cancer.

Increased risk of violent human conflict from scarce resources, forced migration.

Effects of Global warming

What contribution has the on-going Covid situation given to the global warming

On one hand, it helped a lot, as there was less use of automobiles, air quality improved, nature was uninterrupted, electricity was saved in offices, schools, auditoriums, etc., less traffic on roads, all had clean home-cooked food. ate, less animal hunting, fewer unnecessary purchases, and much more benefits.

But on the other hand, more waste due to masks, protective covers, PPE kits; Too much electricity is used in hospitals due to large numbers of patients, lack of food, unemployment, etc.

What is a carbon footprint, and how can we reduce our carbon footprints?

The carbon footprint is the total amount of greenhouse gases that we generate from our daily activities.

The average carbon footprint for a person in the United States is 16 tons, one of the highest rates in the world. Globally, the average is closer to 4 tonnes. To have the best chance of avoiding a 2℃ increase in global temperature, the average global carbon footprint per year needs to be reduced by 2 tons by 2050.

We can reduce our carbon footprints by keeping the following things in mind :

  1. Drive less:  We should use public transport as much as possible and walk or cycle for short distances.

When we need to take our private car, we must follow these steps:-

  • Go easy on the gas and brakes- driving efficiently can help to reduce emissions.
  • Regularly servicing our cars can keep the emissions in control.
  • Checking the tires- Keeping tires pumped correctly can reduce emissions.
  • Avoid Air conditioning and intensive city driving.
  • Not weighing our car down with unnecessary luggage.
  • Carpool- Not only divides cost but also divides the carbon emissions while having a fun time.
  1. Fly Less: Leaving just one extra avoidable flight can keep a lot of carbon emissions off your back.
  2. Eat Less Meat: The production of red meat uses a lot of feed, water and land. Cows themselves also emit methane, a harmful greenhouse gas.
  3. Waste Less: 
  • Take stock – Making grocery shopping lists before going to the store to prevent buying things you don’t need.
  • Be wary of bulk – Low – priced food might seem like a good deal, but it’s not if we don’t end up eating it before it goes bad.
  • Plan – Don’t cook more food than you can eat.
  • Get creative – Reuse leftovers instead of tossing them into the bin.
  • Freeze- Extend the life of food by freezing it properly.
  • What to eat On- Skip the disposable dishes and wash dinnerware by hand instead. If we order takeout, we must wash and reuse the plastic containers that food often comes in.
  1. Heat, Lights and Appliances:According to estimates by the Natural Resources Defense Council, in the average American home, 25% of energy is used to heat spaces, 13% is used to heat water, 11% is used for cooling. and is done on the rest of the equipment. Even small changes in these can make a big difference.
  2. How to Dress Sustainably:  Because of ‘fast fashion’ clothes are produced quickly, cheaply and unsustainably. As the price of our clothes drops, the environmental costs increase.
  • Take a reusable bag to the store.
  • Skip the packaging.
  • Invest in quality products that last.
  1. Buying Local Food and Products reduces transportation costs and packaging waste, and the stimulation of employment in local communities.
  2. Plant a Tree or some flowers to help beautify the area around your house and get some fresh oxygen.

What are renewable sources of energy?

Renewable energy is often referred to as clean energy because it comes from natural sources or processes that are constantly replenished. For example, solar energy, wind energy, hydroelectric power, biomass energy, etc. are renewable sources of energy.

What are non-renewable sources of energy?

Non-renewable or dirty energy includes fossil fuels such as oil, gas, and coal. Non-renewable sources of energy are available in limited quantities and take a long time to be replenished. For example, when we pump gas at the station, we are using a limited resource refined from crude oil that has been around since prehistoric times.

How do renewable energy sources hold up in a warming world?

Renewable energy is very successful because it lowers costs and begins to deliver on the promise of clean energy. Renewable energy supplies 15% of the world’s energy today. We should try to increase this percentage in the next 20 years. Using clean energy does not release any harmful gases, thereby saving our environment.

Why is it important to control global warming?

If we do not go out of our way to contribute to mitigating global warming, we will all have to face dire consequences. Climate change already causes at least 300,000 deaths per year worldwide and climate change could be one of the biggest global health threats of this century.

Why are we neglecting global warming in spite of feeling its effects?

We acknowledge the gravity of climate change on an intellectual level, but don’t live our lives as if the message has really sunk in. It seems likely that most people reading this blog will be in a similar situation: a balance of perfectly conscious evidence but somehow trapped in patterns of thinking and behavior that prevent us from aligning our actions with our awareness.

Are there chances of global warming reducing in the future before it is too late?

Even though climate change is a serious threat that is not going away, it could have a significant impact on how it affects us in the near future. By investing in renewable energy and energy efficiency, people, communities, businesses, and governments can reduce the amount of greenhouse gas emissions reaching the atmosphere and slow global warming. This will help mitigate the consequences of climate change for the present and for generations to come.

Furthermore, through adaptation and resilience efforts, we can and should create an infrastructure to withstand the effects of climate change, which protects the lives of millions of people currently living in vulnerable areas.


Like every drop makes the ocean, reducing global warming by reusing plastic, natural resources, metals, clothes, water, etc as much as possible is essential for me, you and all of us, complete with single-use disposable Kind of avoid items, low-quality products, recycle energy, water, natural resources. Saving resources starts with us. Right now, I am completing my blog to save electricity.
