Global warming has affected the living of people globally. It has become the reason of many environmental and social level changes directly and indirectly all through the world. The emission of greenhouse gases increases the heat on the earth which has created living problem. According to the scientific consensus, it has been noted that the climate changes are continuous because of the global warming.
Bad human activities are the primary driver of the increasing effects of the global warming. Many impacts of climate changes which are clearly observed are glacier retreat, fluctuations in the timing of the seasonal events, earlier flowering of plants, changes in agricultural productivity, increasing heat, etc.
Global warming is like a demon of the ancient time which has taken birth in the modern time after being stronger. It is increasing its negative effects all across the world by slowly increasing the heat and temperature of the globe. Heat as a heat waves persist for many days by getting combined with the high relative humidity of the environment. This heat may work as a killer if the night time temperature does not drop. Increasing temperature has been started feeling by all of us and it is affecting us by decreasing the length of winter season and increasing the length of summer season.
Global warming is regularly calling the natural disasters to occur more often many times a year. Increasing heat and temperature regularly is threatening the human health and safety because it is creating the fear of drought, flood, natural forest and peat fires, melting glacier, decrease rainfall, increasing pollution, rise of epidemic diseases, rise of sea-level, more often occurrence of hurricanes, storm, typhoons when ocean cycles continue, increasing frequency of tropical cyclones and many more.
The effects of global warming are increasing day by day as the causes of global warming are increasing. The main and clearly visible impacts of the global warming is increasing temperatures of the globe, ice caps melting, glaciers melting, removal of ice sheets covering from West Antarctica and Greenland, sea level rise, movement of forest animals to the cooler areas, increased precipitation (means rain and snowfall), hot and dry weather, decreasing length of winter season, increasing length of summer season, changing weather patterns, weakening health status, increasing pandemic diseases, drowning of polar bears, and many more.
It is estimated that if the process of global warming would increase in future without any stoppage, all the glaciers (in Glacier National Park) may vanished by 2070 according to the current rate of retreat.
According to the current data, it has been estimated that sea level may increase from 7 and 23 inches (means 18 to 59 centimetres) by the end of this century because of the continuous melting glaciers. Hurricanes or storm is another big problems coming out as a result of the global warming. It is going stronger day by day like a real demon. Plants started giving flowers earlier the time before their pollinating insects become active. Floods, droughts, declining rainfall, etc are other social issues putting life existence at greater risk.
The effect of global warming has become very clear now which is affecting the natural environmental balance and social life of the people. Global warming has impacted the life to a great extent and disturbed the environmental cycles. It is going worse day by day. It has affected the sea level and caused to rise in the sea level which in turn has become the terror to the finish of the whole world.
Global warming raising the overall temperature which causes glaciers and ice caps to melt and thus the water level is expanding continuously. According to the Intergovernmental Panel on Climate Change of Third Assessment Report, sea level has been estimated to rise around 88 centimetres till the end of this century.
Global warming is increasing the risk of ocean acidification. The percentage of carbon dioxide gas (one of the main greenhouse gases) is increasing in the environment and getting mixed with the sea water causing ocean acidification. It is a very hazardous to the ocean life especially for the coral. Global warming is affecting weathers by making climate so hot or cold and becoming the reasons of hurricanes and earthquakes frequently.
Global warming has become main social problem and global environment. Earth is considered as the only planet where life is possible because of the presence of the water and oxygen however increasing amount of carbon dioxide gas here increasing the chance of making it like other planets in the universe without life.
It is said that global warming is a gradual process however it seems that it is increasing very fast as its effects are becoming so visible. People are feeling its effect in their day to day living. It is very visible that winter season has become decreased and summer season has become increased. The whole environment has become so hot and itchy. Global warming makes us feel that it is far-reaching, long-lasting and as a devastating consequences for this planet. It is gradually heating the earth’s surface, ocean’s surface and atmosphere. It has become the topic of debate on international level in the scientific as well as common community.
Bad human activities have been involved to a great level in promoting the effects of global warming. Burning of fossil fuels, oils, etc are pumping the rise of carbon dioxide (CO2) gas, methane gas and other greenhouse gases in the atmosphere causing heat and temperature. Intergovernmental Panel on Climate Change (IPCC) has stated that there is big link between the human activities and global warming. And also stated that it needs international level participation by the government of the countries to solve it globally and reduce its effects.
The melting the ice (polar ice caps and mountain glaciers) has been started very fast. Lakes, rivers and oceans surface are warming rapidly, animals are migrating because of increasing heat, and plants are changing means the leaf-flush in the spring season to fall in autumn season is longer. It has been recorded by the National Oceanic and Atmospheric Administration that the global temperature has been increased all around the world by about 1.8 degrees Fahrenheit (means 1 degree Celsius). Weather and climate conditions are changing extremely where hurricanes, storms, cyclone, typhoon, droughts, blizzards, rainstorms, etc are the results of it.
Global warming is a hazardous phenomenon going ahead continuously all over the world. It has been irritated by the many human activities. The condition of the environment and society is getting worse and worse. It is an international disaster affecting the humanity in all facets of the modern human life. One of the main effects of global warming is the continuous heating up of the atmosphere. According to the statements of scientists, there is a direct relation between increase in CO2 gas in the atmosphere and increasing temperature of the earth. According to the IPCC report of 2007, it has been noted that the warmest years has been started since 1992.
The increasing heat and global temperature causes melting of the ice caps of poles and glaciers. Melting ice all across the world increases the sea levels by 1.88 mm per year from the year 1961 however it has increased by 3.1 mm per year from the year 1993. In the coming years it would increase to a great extent and call various natural disasters to come more often. Melting glaciers are continuous changing the chemical compositions and temperature of the water. Increasing water temperature has disturbed the sea life and forcing the sea animals to migrate or die. It seems that in the current years the Coral life will be wiped out. Some of the sea mammals (polar bear and penguins) are migrating or dying out because of the changing icy habitat.
Regular melting of the ice caps is increasing the greenhouse gases levels such as carbon dioxide, methane and other greenhouse gases which are trapping heat from the sun and warming the whole environment. Melting ice bodies are greatly contributing to the albedo effect which is directly affecting the geographical life. The important function of the ice bodies is to reflect back the extra sunlight and causing cooling effect of the earth, however if they are melting who one perform this function. It has forced the weather patterns to change and called various natural disasters like storm, drought, flood, cyclone, typhoon, thunderstorms, hurricanes, volcano, tsunami, rainstorm, etc.
Earth warming on regular basis has increased the chance of increasing pests and other disease causing insects like mosquito, culex, dengue mosquito, etc. All the effects of the global warming have deadly affected the human lives both physically and mentally. So, it requires some urgent basis solutions to be solved in few current years.
Introduction
Global warming refers to the continuous rise in the average temperature of earth’s climate system, mainly due to human induced factors. The largest human induced factor contributing to global warming is the emission of green house gases like – carbon dioxide, nitrous oxide and methane etc. Large quantities of green house gases results in a larger green house effect, resulting in raised atmospheric temperature. Scientists reveal that earth’s average temperature is rising gradually every year and is about to be raised by 4° Celsius at the end of this century.
Effects of Global Warming
Global warming has raised earth’s surface and atmospheric temperature resulting in effects like extreme climate changes, arctic sea ice decline, sea level rise and warming of oceans along with others. Some of the most significant effects of global warming are described below-
1) Extreme Climatic Changes
Global warming has resulted in extreme climatic conditions all over the world. Unexpected changes in monsoon pattern are being witnessed. Winters are getting colder and summers are registering higher temperatures never recorded before. Occurrences of draught, famine and storms have increased in the gone decade. Though, the climatic variations vary from place to place, it is more evident in some places than the others.
2) Rising Sea Level
One of the most devastating effects of global warming is the rise in seal levels. The seal level is estimated to have risen by 8 inches in the gone century and is still rising, possibly due to global warming. Global warming causes thermal warming of sea water making it to expand. Also factors like melting of glaciers and ice sheets due to global warming, contribute to raised sea levels.
3) Decreased Snow Cover
Global warming results in melting of snow, quickly than it should and results in a decreased snow cover. Satellite images have revealed that global warming has caused reduced snow cover over the northern hemisphere, consequently resulting in raised sea level and hotter climate. Similarly the ice sheets in Greenland and Antarctic have decreased considerably.
4) Ocean Warming
Global warming also results in warming of the ocean. Though the recorded growth in ocean’s temperature is low than the earth’s surface temperature, nevertheless, it affects marine life up to a larger extent. Many marine species are sensitive to temperature changes and ultimately die because of it. The most vulnerable ocean organism to temperature change is coral.
5) Melting Glaciers
Global warming has led to melting of glaciers, throughout the world. Rise in earth’s average temperature, heats up the glaciers, which melt, leading to other climatic and geographical effects. Global warming has resulted in glacier retreat in Alps, Andes, Rockies and Himalayas. Melting glaciers have led to raised water levels of oceans and rivers, increasing the possibility of floods.
6) Decreased Oxygen Level of Oceans
Heated water has a lower gas absorbing capacity than colder water. Hence, when the ocean water temperature is raised by the global warming, it emits oxygen, rather than retaining it. This in turn has disastrous effects on aquatic species which rely on the supply of oxygen; thereby, resulting in decrease of fishes, turtles etc.
7) Lower Food Security
Global warming results in unexpected climatic changes and increased possibility of floods due to raised sea levels. These effects all together result in poor crop production, especially in the low lying agricultural areas. The effect of global warming on agriculture production varies from place to place and largely depends on the condition of rainfall.
8) Extreme Events
Global warming is causing extreme events at different locations throughout the world. These extreme events include extreme weather, hurricanes, drought and tsunamis. An increase in earth’s temperature causes unusual weather patterns resulting in hurricanes and cyclones. Also, raised water level results in floods and famine.
9) Fire
Many forest fires in recent past have been attributed to global warming. Global warming has subsequently resulted in raised climatic during summer and extreme heat waves, increasing the possibility of fire.
10) Oceanic Acidification
Oceanic acidification is one of the major effects of global warming on oceans. Global warming leads to increased atmospheric concentration of green house gases like carbon dioxide (CO2) and Methane (CH4). These gases dissolve in ocean water, making it acidic. Oceanic acidification has negative effects on aquatic life and humans as well.
11) Depletion of Water Resources
Global warming results in larger rate of evaporation and hence in faster depletion of natural water resources. The situation is more critical in places with dry and arid climate. Such places when faced with more extreme climates fast lose their natural water resources.
Conclusion
Global warming is caused due to human induced factors and has the potential of causing havoc on planet in many ways. Moreover, the intensity of global warming is increasing with every passing year and if the situation continues, it will have unimaginable disastrous consequences. Only human have the power to reverse the change or at least to minimize its effects, and every possible effort must be made in this regard.
