Ever imagined about swimming and sailing in warm oceans? Ever imagined the earth without ice in its poles? Well, if not, start thinking of it because global warming is taking us on the verge of it due to modestly high temperature rise in pat few centuries.

Global Warming is an average increase in the temperature of the atmosphere near the earth’s surface and in troposphere, which can contribute to changes in global climate patterns.


The main causes of global warming are:-

  1. Greenhouse Gases (GHG)
  2. Ozone Depletion
  3. Aerosols in the atmosphere.

global warmingHowever the causes may be split into two groups, man-made or anthropogenic causes and, and natural causes.

One natural cause is a release of methane gas from arctic tundra and wetlands.

Man-made causes are population and pollution. Population and pollution are directly proportional to each other and produces most of the GHG like Carbon dioxide, CFCs, methane, nitrous oxide, etc.


Global warming has a great and direct impact on rising sea levels, melting ice-caps and significant worldwide climate changes. It proves to be a fundamental threat to all living things on the earth.

Figures released by Munich Re, one of the world’s largest reinsurance companies at the end of Dec 1998 indicated that natural disasters across the globe were 3-fold now as of then 25 years ago.

The human cost of some 50,000 death alone is high. Floods during the year were responsible for 85% of economic losses of about $1 b, 9 times more in real terms than 25 years ago.

Paleoclimate information supports the interpretation that the warmth of the last half century is unusual in atleast the previous 1300 years. The last time the polar regions were significantly warmer than present for an extended period (about 125,000 years ago), reduction in polar ice volumes led to 4 to 6 meters of sea level rise.

Large tracts of low lying land across the globe are rapidly becoming uninsurable notably those in the Carribean, Pacific and parts of Asia.

The Intergovernmental Panel on Climate Change(IPCC) currently estimated that  global warming is occurring at a speed of between 1.4 – 6.4 degree centigrade every century which sounds modest but could raise the sea-levels upto 1m in the same period.

Some 20 states including the Maldives, Nauro, Kiribati, the Seychelles, Antigua, Barbuda and the Federated States of Micronesia are at risk of becoming uninhabitable through the saline pollution or through simply being submerged.

It is projected that 80% of the main island and its capital will be under water within a century. Vulnerable coastal cities range from New Orleans in the USA to Bangkok, Hong Kong, Shanghai, and Tokyo in Asia.

By 2020, 75-250 million people of Africa will be exposed to water scarcity due to climate change.


Approximately 20-30% of plant and animal species are likely to beat increased risk of extinction if increase in global temperature exceeds 1.5-2.5 degree centigrade.

Of over 1,400 species analyzed , ranging from fish and mammals to grasses and trees, over 80% are migrating to higher latitudes or higher elevations and altering their annual routines in response to global warming. Amphibians have also shown particular vulnerability.

In mountains around the globe, many species, including the golden toad and most of the 70-odd species of harlequin frogs, have vanished or declined because of diseases spurred by climatic changes.


Human caused global warming may have already doubled the chance of killer heat waves like the one that hit Europe in July and August of 2003. That summer was likely the continent’s hottest in 500 years. The relentless heat killed almost 27,000 people, breaking all records worldwide for heat induced human facilities.

In April-June 1998, 3,028 people died in the most disastrous heat wave to ever hit in India. In 1995, a five-day heat wave caused 525 deaths in Chicago, with the 41 degree centigrade reading on July 13 the warmest july temperature ever measured.


The last 25 years have witnessed a higher incidence of coral bleaching events which can lead to coral death. In 1997-1998 alone, the largest bleaching record seriously damaged 16% of the reefs in the world and killed 1,000-years old corals. Mass bleaching are usually caused by excessively high temperatures.


Glacier National Park in Montana, had lost two-third of its ice since 1850; with uncontrolled warming, the remaining glacier could disappear by 2030.

It is estimated that the Gangotri Glacier, the source of the sacred river Ganges in India would be gone as soon as by 2030 due to global warming.

In European Alps, ice that had hidden and preserved the remains of a Stone Age man melted for the first time in 5,000 years. Venezuela had six glaciers in 1972, but now has only two; these too will melt away in the next ten years.

mt. kilimanjaro before and afterIn Africa, 82% of the ice on Mt. Kilimanjaro had disappeared since 1912, with about one-third melting in just the last dozen years.

The National Snow and Ice Data Center (NSIDC) is now set to give updates about the surface melting on the Greenland Ice Sheet. The 2012 melt season was far greater than any year which began in 1979. There were over 120 melt days for low elevation areas along the south-west coast. There were over 100 melt days across parts of far north and south-east coastal areas. Melting in 2012 lasted almost two months longer than average. There was even some melting at the 10,000 foot elevation summit in July, which is extremely rare.

The other effects of Global Warming are:

  • Increasing temperature and acidity of the oceans.
  • Warmer winters
  • Frequently deadly heat waves.
  • Loss of biodiversity
  • Gender bended lizards
  • The north-west passage comes to reality
  • Giant sand-seas in Africa, and many more.

images (2)The north-west passage is a short-cut between Atlantic and Pacific oceans through the Canadian Arctic.It would save some valuable time and fuel for ships that travels through Suez canal in Egypt and Panama canal in Central America.It became reality 30 years before the scheduled time.



Carbon Taxation and Carbon Trading approach came to curb the global warming. Taxation in some form is certain to come and modest initiatives have been taken by the UK with an introduction of the Climate Change Levy (CCL) and in Germany.

Other preventive measures of global warming are :


  • Reduced use of Fossil fuels.
  • Plantation
  • Water conservation
  • Recycling of products
  • Use of public transportation, etc.

    Global warming is the big burning issue in today’s world. Real cause of global warming is human beings.
    Many people knows about global warming and its effects but they ignore that.This little carelessness lead us to hell.So human beings should take this matter seriously because everybody wants to live,nobody want to die.
    This article is very good to aware people of global warming. After Reading this article i came to know how global warming is changing this beautiful earth. so we need to serious about this matter.

  2. Nilay Mazumder says:

    Man-made global warming is the widely accepted theory that human industrial and commercial activity is quickly heating up the Earth. Many scientists believe this rise in temperature could render large parts of the planet uninhabitable.Climatologists, who predict short and long-term climate trends, believe carbon dioxide and other emissions, mainly from industrial and commercial activity over the last two centuries, have altered the Earth’s atmosphere. This change has caused a “greenhouse effect” which is rapidly warming the planet.The predicted effects of global warming include the melting of polar ice caps; a significant rise in sea levels; more extreme weather events; a reduction in agricultural land; water shortages; food shortages; loss of rain forests; and more species becoming extinct.Scientists believe all nations must take immediate and urgent action to dramatically reduce carbon emissions. Technological solutions have been proposed, ranging from “carbon scrubbers” that remove carbon from the atmosphere and reduce greenhouse gases to placing giant mirrors in space to reflect enough sunlight to cool down the planet.

  3. Chandreyee Ghosh says:

    Global Warming is really a big problem in today’s world. It is leading the world to the way of disaster. The ice caps are melting so rapidly that the sea level is already risen 4 to 6 meter. Temperature is increasing day by day and many wild animals and plants are already extinct and some species are counting their days.
    We all know that these are very big problems and the cause of this kind of environmental disbalance is also known to us . But the problem is we are not concerned enough and inspite of knowing all the effects of our activities we are repeating those things.But this is entirely our responsibility to save our planet from any massive disaster.
    It is not possible by only making campaigns. We all have to feel the problem from our soul. Only then we can save environment.Some very small steps can save the earth like, use of bio gas instead of coal, Public transport instead of private car, preservation of water etc.. So at first we all have to be literally eco friendly , only then it will be possible to save the world from the effects of Global Warming.

  4. Chaitali Mallick says:

    Human Activities are the major reason for the Global Worming.. So Everyone should be concern about it. and everyone should have the knowledge of this Global worming otherwise Global Worming may be dangerous for all the living beings on earth.

  5. Anamika Tomar says:

    “GLOBAL WARMING”-A real threat to the nature.
    Ozone layer depletion is the biggest cause which leads to rise in temperature which ultimately causes global warming.
    I would request to all the peope to minimize the usage of those equipments(for ex-air conditioners etc) which releases the CFC’s(chioro floro carbons) and other harmful gases.This step can largely prevent the ozone layer by decreasing its depletion rate.And this is how global warming can be prevented.
    This can further prevent the nature to face sudden climatic changes and finally save the human lives.

  6. SHRUTI PRIYA says:

    GLOBAL WARMING has become a real threat for this beautiful and lovely planet EARTH. According to the survey, GANGOTRI is shrinking 23m every year threatening water shortage for millions of people. Now, the time has come to think upon this problem and act smartly. Each and every 1 should follow “5R” discussed in the article. The world community should respond and adopt a lifestyle that leaves behind a livable world for the generation to come.

  7. Akash Tripathi says:

    Ever since the birth of human species on earth ,the environment is feeding humans with all its resources. But slowly and gradually with the so called industrial revolution followed by the technical age has been exploiting the natural resources in an unnatural way leading to global warming. Its a burning issue and should be tackled as soon as possible, this article is worth for enlightening the public and following the preventions suggested.

  8. Debanki Mukherjee says:

    GLOBAL WARMING is damaging the entire FLORA and FAUNA . As a whole global warming is destroying the entire ecosystem.The above article explains about the adverse effects of global warming.

  9. Neha S says:

    i know you all have heard it a hundred times, you even have seen movies on it… but its not as interesting and tempting as it is predicted in the movies, it is in fact a call from the nature to save it from the adverse human effects.
    We all know about global warming what is it.. obviously as the name suggests GLOBAL= EARTH and WARMING= HEATING, i.e EARTH HEATING, so what will happen if the earth heats up?
    If you want to know this is the article that will help you out..

    • Gourav Jain says:

      GLOBAL WARMING -: The change in the climatic condition lead in the revival of wide variety diseases caused by insects like Mosquitoes(Malaria) . Its also lead to an increase in droughts , hurricane , decrease in annual rainfall as well as melting of Polar ice caps. Formation of Photochemical Smog which directly effects the human health and cause loss of biodiversity and animal extinction. So , to avoid this reduce the use of fossil fuel , CFCs ,as wells radioactive material .

  10. diya mukherjee says:

    at present almost each and every indivisual is concerned about one of the deadly problem of earth and that is Global Warming!!!what is global warming? it is an average rise in temperature on earth’s surface and troposhere affecting the climate and diversities of the earth.mainly green house gas, ozone layer depletion and presence of aerosols in atmosphere has contibuted to global warming to a greater extent. the effects of global warming can be felt in today’s life like unbearable heat in summer sudden changes in climate, natural hazards leading to high death tolls of humans and wild life etc… if measures are not taken this beautiful world with large diversities will defintely come to an start planting tree, use less plastics and take on the reqiured steps in order to save our planet from a dreadful end….

  11. Gourav Kumar says:

    Global Warming is the biggest concern for the people in the current scenario. It is affecting the human being in a major way, one of the biggest threat of the effect is the depletion of ozone layer which resulting the Sun’s ultraviolet radiation to affect the living organisms directly. The Earth’s average temperature is increasing year by year and its affecting the Eco-system.

  12. sumit mukherjee says:

    Global warming is the burning topic of our world. Including the first world countries along with the third world countries, all are anxious about that. Starting from the reduction in polar ice volumes to the killer heat waves all because of this effect. It hits our natural environment directly. Diseases mainly like cancer and any many other increases rapidly with respect the last few decades. Carbon Taxation and Carbon Trading approach can control this effect quite a lot. As well as we have to look for a another issue that is the use of CFC. Above all, yes we have a way to get rid of this problem.

  13. K Rohit says:

    For me Earth is like a big family and in a dysfunctional family, members of the family are quite normal about the adverse changes in the family, they think that its the same for every other family nobody steps up and votes his opinion about the wrong doing in the family. Similarly we have gained the same feelings for the changes that is being brought about in the ecosystem and ignore it. It is the people who have to change their way of thinking to bring about any change at all, or else we are going to be extinct very soon.

    DO YOUR PART to FIGHT Global Warming…..

  14. shreya sarkar says:

    When environmental education was introduced to us I thought that it as a burden, but when I started studying the subject I realized how important it is not only to us but to every person on this earth. The knowledge of the environment led us to know about global warming and its consequences. How polar caps are melting, how there is being a shift in the climates, unduly rains, droughts are followed by floods, we have early and longer lasting summers etc. The solution to these problems lies within us. We have the potential to bring about a change by REFUSING , REDUCING, REUSING and RECYCLING. If we want we can bring about a change and hence make this earth a better place to live in!

  15. sibanjan says:

    global warming is the rise in the average temperature of the earth atmosphere. deforestation using of fossil fuels causes green house gases (ex:- chlorofluro carbon or cfc) which is responsible for global warming.. its a great threat to to future world…. as the water level is rising up continuously …. and the stocked ice of the polar region is melting down day by day…. ozon (o3)lair in the atmosphere also got affected ….
    there are many causes behind global warming… but we have to find out a way to get rid of it…. first of all planting trees is needed….. trees can control the air cycle and the weather cycle (like rain, temperature etc)
    after that limited use of bio fuels should be adopted… we have to focus on the substitute energy sources like solar energy ,, bio gas energy,, fluid energy (water and air)… pollution should be controlled in a proper manner..leaded petrol ..use of carbon monoxide should be banned….
    finally it can be said that we have to take care about the nature… so that we can expect the nature will take care about us….

  16. oishi chatterjee says:

    When we are talking about global warming, we are not talking about how this summer the temperature were hotter than last years.Instead we are talking about the climatic changes that happen to our earth over a period of time.
    In this article we can go through the adverse effects of climatic changes and certain immediate effects observed. This is the need of hour that we need to take steps for prevention from global warming.
    Global warming is not a conqueror to kneel before but a challenge to rise to…

  17. Amit Kumar says:

    The nature has its own rules and is self-balancing. The environment is a versatile example of extreme level self-management system where everything is in acute balance. Different places, different environment, different habits and different species, that too in a balanced proportion. but the whole world is threatened in the past decade by a sudden climate change. The whole concept is called Global Warming.
    Global warming has become one of biggest burning problems of not only India but the whole world. It threatens the health of the earth’s inhabitants and the world’s economies every day. With global warming comes longer and more intense heat waves and storms. Along with those climate changes, come more pests which in turn can carry devastating diseases. Forestry and farming are feeling the negative impact of global warming and we’re also seeing traces of a devastated ecosystem.
    Rally good article, got to learn a lot.

  18. Atif Pall says:

    Global Warming is a major problem which our environment faces today terribly.
    This global warming is caused due to Greenhouse Effect.
    What is greenhouse effect?
    It is a condition in which Earth’s heat trapping increases more from the normal levels.
    The possible remedies might be forestation in this regard. Planting more trees and reducing timber cuts worldwide will help restore the imbalance. Going further we must follow on environmental policy of “REDUCE, REUSE, RECYCLE”’, i.e. promoting the reuse of anything. Adding on , the use of fuel-efficient vehicles should be promoted as these vehicles have lower emissions of harmful gases.
    Last but not the least, every individual should be aware of the importance of the protecting environment. Eco- friendly technologies must be entertained.

  19. Saheli Dasgupta says:

    Global warming is a matter of grave concern today. we have been exploiting nature to its fullest mostly unethically. so, now its our turn to be paid back in the same coin. i hope people reading this article would be enlightened about global warming and its adverse effect on the very existence of mankind. we all can contribute to prevention of it if we are a bit more careful. we can start by using lesser amount of vehicles emitting poisonous gases causing depletion of ozone layer and thereby contributing to global warming. we can use car pools, avoid using CFC products, plant more trees etc. a united effort is needed to save the existence of our next generation. as we already come to know about the vanishing glaciers from this article, our sea levels have risen and if action is not taken immediately we might have to face serious consequences.

  20. Manisha Chawla says:

    Global Warming has become very possible- impossible issue for the nation.To understand it clearly,its causes and its impact is really a very big matter.This article can help a lot to general public to know about it upto a certain extent so that they can help to avoid its causes in their own way.

  21. Rohit kumar says:

    An awesome article on global warming ,came to know things that we we should have been concerned off in past,but once a great man said “past cant be changed but future lies in your hand”.Hence in this present era
    of innovative technologies Possibilities is a word which has no limits. So,in future we should opt for those technologies which will cause harm to our environment.We should energy resources like solar energy,which can be used in our day to day life e.g. solar cooker,solar cell,etc.This can lead us to a bright and pollution free world.

  22. Harshita Rathi says:

    Global Warming is the biggest issue in the country. Due to this global warming heat increases on earth. scientists are trying their best to stop this. we also have to take positive actions to protect our planet from this big disaster. we can contribute to make our environment healthy.

  23. Urvashi Khanduja says:

    Global Warming is really a big issue as it results in change in the climatic conditions. Cutting of trees is the major cause of global warming. Our scientists trying their best to stop global warming. There are so many measures by which we can protect our environment. I think it is not only the duty of scientist to protect our environment from drastic changes, it is the responsibility of each and every person in the world.
    As soon as possible no serious action will not be taken then the survival of human beings is not so easy.

  24. Vipin Sahu says:

    Global warming is a great matter of concern for nation.there are many dangerous effect on human life as average temperature is increasing – discomfortable living especially in hot countries,melting of ice near poles this results in increase of sea level & many islands are merging in sea.The rainfall becomes uneven in magnitude resulting many crops may slowly vanish.The difference in day & night temperature shall reduce.

  25. Priyanka Baidya says:

    Global warming has become the most important issue of our life for every one,every state and every country.
    There are so many effects of global warming, most important of them is , increasing of temperature and the continuous change of climate globally.
    The main reason of global warming is Green house gasses.
    And also we,the human being is very much responsible for this situation.
    So, its almost depends upon us how we handle this situation.
    We should follow some restrictions like reduction of usage of private car, fossils and fuels.
    We should do plantation to save the nature and to maintain a balance of oxygen and green house gasses to get out from the global warming.

  26. sanjana kumari says:

    Nowadays GLOBAL WARMING is becoming a major issue and problem of all the nations across the globe. When it comes to connecting the dots between climate change, extreme weather and health, the lines are clear. The earth is saying something with record heat, drought, storms and fire. Scientists are telling us this is what global warming looks like.Carbon pollution is the main reason our planet is getting hotter, increasing the chances of weather disasters, drought and flood and hurting our health.
    But not to worry, there are solutions. For starters, we can cut carbon pollution by reducing our dependence on fossil fuels and increasing our use of clean, renewable energy. And we can implement policies that help us prepare for flooding, drought, storms and other consequences of climate change.
    I would recommend people to read this article and go through the various other adverse effects and causes of GLOBAL WARMING.

  27. Kriti Das says:

    Global warming is the biggest issue of concern for all of us right now. I still don’t find a lot of people bothered or doing their bit to stop it.Lack of information can be a reason.We all can contribute to this cause by taking care of small things like using star marked electrical appliances that release less cfc,less burning of fossil fuel by arranging for car pool etc.It is high time that we realize how grave the situation is before it is too late.

    • Barun kumar singh says:

      After reading the article i got to know many things about which i was not aware of like damage to coral reefs and many more.really global warning is a great matter of concern for every individual and nation.this article can be made more attractive by adding the points on melting of glaciers in Atlantic oceans and rise of sea level
