Global warming is the biggest challenge facing our planet. It is current and widely discussed factors. It has a reaching impact on biodiversity and climatic of our planet. Global warming represents a warning to living things on this planet. The global average temperature rose during the past 100 years. The scientific view is that most of the temperature increases since 1950 has been caused by increases in greenhouse gas concentrations produced by human activity. Scientists agree that planet’s temperature has risen 0.5 degree Celsius since 1900 and will continue to increase.
As a result, the world is getting warmer. The year 1990 was the hottest year in the last century. Global warming is used to refer to any warming of surface air during the past 2 centuries that can be traced. Global warming is related to the general phenomenon of climate change, which refers to changes in the totality of factors that define climate. In addition to changes in air temperature, climate change also involves changes to winds, ocean and other measures of climate. Climate change can be viewed as the combination of many forces occurring over diverse timescales.
Since human civilization, climate change has involved a human-caused element and this element has become more important in the industrial period of the last 2 centuries. The imbalance which we have created between our life and earth is showing the signs of disasters in the form of flood, landslides, and drought. If the imbalance continues to rise, one day this will post a question mark on the existence of this planet. Carbon dioxide is an important constituent of the environment is causing a warming effect on the surface.
Global warming is the current increase in temperature of the Earth’s surface both land and water as well as its atmosphere. When the Earth experienced increases in temperature it was the result of natural causes but today it is caused by the accumulation of greenhouse gases in the atmosphere produced by human activities. Scientific research has shown that with more than 90% certainty that this increase in overall temperatures is due to the greenhouse gases produced by human’s Activities such as deforestation and the burning of fossil fuels. These findings are recognized by the national science academies of all the major industrialized countries. Global warming is affecting many places around the world. It is accelerating the melting of ice sheets and permafrost which is causing average sea levels to rise. It is changing weather patterns in different places and making some places dryer with more intense periods of drought.
These changes have affected both natures as well as human society and will continue to have increasingly worse effects if greenhouse gas emissions continue to grow at the same pace as today. The natural greenhouse effect maintains the Earth’s temperature at a safe level making it possible for humans and other lifeforms to exist. However, since the Industrial introduction, human activities have significantly enhanced the greenhouse effect causing the Earth’s average temperature to rise. This is creating the global warming we see today. To put this increase in perspective it is important to understand that during the last ice age, a period of massive climate change, the average temperature change around the globe was 5°C.
Earth’s temperature is determined by the Sun. hardly 29 % of sunlight is reverted back into space because of surfaces like cloud or ice. Remaining 71 %, most of them are being captured by the ocean, land, and the rest is absorbed by the environment. The absorbed solar energy heats our planet. As rocks, air or seas warm, they radiate heat energy. This energy travels into the atmosphere where much of it gets absorbed by water vapor and greenhouse gases such as methane. When they absorb the energy radiating from a surface, water & greenhouse gas molecules turn into tiny heater like the bricks in a fireplace, they radiate heat even after the fire goes out. They radiate in all directions. The energy that radiates back toward Earth heats both the lower atmosphere and the surface, increasing the heating they get from sunlight. This absorption and radiation of heat by the atmosphere and the natural greenhouse effect is beneficial for life on Earth. If there were no greenhouse effect, the Earth’s average surface temperature would be a very chilly instead of the comfortable that it is today.
Temperatures are sure to go up. It appears that the temperature is rising at a rate quicker than ever. Human activities like an increase in pollution and industrialization are viewed as the factors accountable for the rise in global warming. The proof that humans are causing global warming is strong, but the question of what to do about it remains controversial. Economics and politics are important factors in planning for the future. Even if we stop in giving out greenhouse gases today, the Earth would still warm to another degree. So. But what we do from today which will make a big difference. Governments and NGOs are already working hard to cut greenhouse gases and everyone can help in this noble cause of humanity.
Global warming can direct us to immense water and food shortages. It has a life-threatening impact on the wildlife. Droughts, wildfires, extinction of endangered species, storms are some of the effects of global warming. Emissions like co2, nitrous oxide and other greenhouses gases will stay in the environment for many years making impossible to eliminate global warming for several decades. Global warming that is causing upmost weather to alter has shown its implications in the way of forest fires or heat waves.
A common objective is too stable Green House Gases concentrations around 460-560 ppm or around twice pre-industrial levels. This is the point in which many believe the most damaging effects of climate due to global warming can be avoided. We did have to reduce Green House Gases emissions by 40% to 70% of what they are on a path to be in the next century to towering this level. Present concentrations are about 378 ppm, which means there is not much time to lose.
The global warming hypothesis states that the rise in atmospheric co2 will boost the greenhouse effect, important in raising global temperatures and having destructive consequences. An admirer of this hypothesis argues that Ground-based calculations show that average global temperature is 0.51° C higher than a century ago and Air temperature over the ocean is also determined. Computer models predict rises in global temperature as high as 8° C by 2100, resulting from concluded increases in atmospheric carbon. This is also imagined to have different effects including sea level increase, the rise in disease and famine in numerous areas, extinction of plants and animal species, and more harmful weather. Many went on to argue that we require taking powerful action to keep off this predicted aftermath of the catastrophic rise in temperature. They project striking limits on energy use.
To achieve the study of global warming, this research uses a qualitative approach that explores, emphasizes meanings and experiences. It is also considered as descriptive research because reasonable knowledge has been achieved, however more detail information is still needed to be addressed. Therefore, structured interviews, focus groups, and questionnaires are more likely to be used in this. This research was carried out with the help of survey information as well as some article regarding Climate change. We did this research by analyzing the speeches of world leaders on this issue. Media reporting on global warming had also taken into consideration. Study case of global warming and national approach was helpful.
The GHG will remain in the environment for many years. The consequences that global warming’s cause on earth is extremely severe. There are various outcomes that will take place in the future if global warming continues. That comprises the economic aftermath and more hurricanes. Additionally spread of diseases and earthquake can be a problem. The 1st effect is polar ice caps melting. As the temperature rise, the ice at the North Pole will melt. Once the ice melt effect will be raise on sea levels because the melting part becomes oceans. It affects low lying areas such as the Netherlands. The Netherlands will be surrounded by water once this happens. It is not going to occur so fast but the sea level will continue to increase.2nd effect is the species loss of habitat. Species that comprise polar bears and tropical frogs will be extinct because of climate change. Various birds will migrate to places because animals are not like humans. They can not adopt the habitat that changes their living and temperature.another effect is that more hurricanes will occur and economic consequences will get impact as well. Hurricane causes harm to houses and government to require to spend billions of rupees in damage and people demand places to rest or have been killed. Once a disaster happens many people have died and diseases happen. Diseases are serious because it can spread to other people fast and more people will get the disease and the disease generally come more serious because of different climate condition.FINDINGS Global warming is affecting the Earth’s weather as well as the physical atmosphere. Most visible effects of global warming can be seen in the Arctic as glaciers, permafrost and sea ice are melting rapidly and it can cause the sea level to rise. Global warming is affecting the atmosphere in many ways including the sudden rise in temperature, Desertification, Increased melting of snow and ice, Sea level rise, Stronger hurricanes and cyclones.
How can we stop global warming? we need to Speak up on this serious issues. we need to power our home with renewable energy. we need to invest in energy-efficient appliances. we should reduce water waste and conserve it. we should buy better bulbs and pull the plugs accordingly. driving fuel efficient car is also a better idea and shrinking of carbon profile is a must.
Overall I have understood that our earth is sick of many problems. We humans need to heal the earth in a right way. Global Warming has caused many troubles for human but humans are a reason to make global warming happens. Many people have died because of disease or disaster. It also affects the economics of the country. However, there are many solutions to it. the problem can still be under control and world is working in that direction but it is individual’s duty to understand their role and perform it to a high standard in order to save this planet.we should to reduce the global warming by less use of gasoline. recycle is also a key for mankind. we all know the story of 3 Rs and their importance. human should help to reduce global warming instead of making the earth temperature increased. Our generation should start taking care of the earth because the next generation will suffer if we fail to reduce global warming. Therefore, We are learning it because we need to understand the effect of climate change that will affect us and we can start saving the earth.
It is really difficult to find the motivation to act now to prevent something that possibly, maybe, just might happen 100 or years from now. When the effects of global warming are so far beyond the imagination, there seems to be an incentive to act. it is not that we all are anti-environment. It is just that we are thinking of ourselves as being busy to be actively in favor of it. In this fast-paced world, we are struggling to keep up and for that reason, we may not be inclined to slow down in order to sort and recycle.
It would be very interesting to conduct a study of the world joining live in the future of global warming on a single platform. Further research on a scientific solution to this problem. Booth level implications and climate change reasons can be analyzed.
