Global Warming is a long-term rise in the average temperature of the Earth’s climate system, an aspect of climate change shown by temperature measurements and by multiple effects of the warming. Most people might think that global warming is caused by human activity; however, environment have caused global warming itself as a result of climate changes, nature disaster, and changes in the Global warming causes , deaths a blogger.comse, according to research published in Nature, by , rising temperatures could lead to the extinction of more than a million blogger.comted Reading Time: 9 mins Drought under global warming: areview Aiguo Dai ∗ This article reviews recent literature on drought of the last millennium, followed by an update on global aridity changes from to Projected future aridity is presented based on recent studies and our analysis of model simulations.

Most discussions onglobal warming today cite a correlation between an increase in global temperature and the increase in carbon dioxide, nitrous oxide, methane, and chlorofluorocarbons CFCs in the atmosphere. Human activity increases the amount of these gases in the atmosphere and, as a global warming research paper of the greenhouse global warming research paper, increases the earth's temperature.
As the earth's temperature rises, global warming research paper, glaciers melt, ocean levels rise, and unusual weather patterns occur, global warming research paper.
Scientists warn of the loss of ecosystems and the endangerment of human lives and communities as a result of climate change. The ozone layer also plays a critical role in global warming. The ozone layer refers to an upper layer of the earth's atmosphere containing a high concentration of ozone gas that absorbs potentially harmful ultraviolet radiation. Scientists have made the case that CFCs, which were non-existent until the twentieth century, are responsible for depleting the ozone layer.
Most scientists also agree that global warming is the result of human activity. Opponents argue that the correlation between higher levels of greenhouse gases and the earth's global warming research paper trend do not necessarily mean that the greenhouse gases are causing the trend.
Many see warmer temperatures as part of the normal fluctuations that occur over long periods of time. They also cite the ability of naturally-occurring volcanic eruptions to cause temporary changes in weather patterns and levels of gases in the atmosphere. The body of research on global warming undertaken during the twentieth century has resulted in many governmental policies that affect individuals, business, and industry. Environmental regulations, global warming research paper, and their effect on businesses, fuel the controversy surrounding global warming.
Basic Definitions and Concepts Related to Global Warming and Climate Change Environmental Regulation:State and federal statutes intended to protect the environment, wildlife, land, global warming research paper, prevent pollution, aforestation, conserve water, global warming research paper, develop and follow general plans and prevent damaging practices.
Currently the earth's average temperature is 15 degrees Celsius. Increased levels of CO 2CFC, Methane, and Nitrous oxide trap more global warming research paper as it radiates from the planet's surface, raising the global temperature of air and ocean water.
The gases include carbon dioxide, methane, water vapor, ozone, and nitrous oxide. It forms a thin layer approximately 10 to 25 miles above the earth's surface that global warming research paper to block ultraviolet radiation. These include CFCs, halos, methyl bromide, carbon tetrachloride, and methyl chloroform. Most discussions on global warming today cite a correlation between an increase in global temperature and the increase in carbon dioxide, nitrous oxide, methane, and chlorofluorocarbons CFCs in the atmosphere.
Macro Level : Global Condition Global Warming Is Creating Perfect Crop Conditions :Without a doubt, global warming is affecting global crop production. The tremendous improvement in global crop production and worldwide growing conditions during recent decades is one of the most important yet least reported news events of our time. As the earth continues to recover from the abnormally cold conditions of the centuries-long Little Ice Age, warmer temperatures, improving soil moisture, and more abundant atmospheric carbon dioxide have helped global warming research paper about a golden age for global agricultural production.
Global crop yields have also registered spectacular growth as global temperatures have warmed. Global grain harvests have nearly tripled since As is the case in the U. During the past decade, African nations have registered record harvests in a variety of crops, including corn and rice. Moreover, the modestly warming climate is stimulating more frequent and abundant rainfall which, together with more atmospheric carbon dioxide, is greening the African continent. Sinceabout 6.
This is an increase of 3. Recent studies have stated that global warming is the cause of these wildfires and higher temperatures, and that the incidence global warming research paper these natural disasters is likely to increase. One reason that wildfires caused global warming research paper climate change have such dramatic effects on the environment is that they act as part of a positive feedback loop with global warming.
As temperatures increase, wildfires become more prevalent, which contribute carbon to the atmosphere. As this cycle progresses, climate change and wildfires both increase in frequency and severity. Mezzo Level : Condition of Global Warming in South AsiaThe effects of global warming on the South Asian subcontinent vary from the submergence of low-lying islands and coastal lands to the melting of glaciers in the South Asian Himalayas, threatening the volumetric flow rate of many of the most important rivers of South Asia and South Asia, global warming research paper.
In South Asia, such effects are projected to impact millions of lives. As a result of ongoing climate change, the climate of South Asia has become increasingly volatile over the past several decades; this trend is expected to continue. Ongoing sea level rises have already submerged several low-lying islands in the Sundarbans, displacing thousands of people. Temperature rises on the Tibetan Plateau, which are causing Himalayan glaciers to retreat.
It has been predicted that the historical city of Thatta and Badin, in Sindh, Pakistan would have been swallowed by the sea byas the sea is already encroaching 80 acres of land here, every day. The first among the countries to be affected by severe climate change is Bangladesh.
Its sea level, temperature and evaporation are increasing, and the changes global warming research paper precipitation and cross boundary river flows are already beginning to cause drainage congestion. There is a 5 reduction in fresh water availability, disturbance of morphologic processes and a higher intensity of flooding and other such disasters.
Bangladesh only contributes 0. Around seven million people are projected to be displaced due to, among other factors, submersion of parts of Mumbai and Chennai, if global temperatures were to rise by a mere 2 °C 3.
This is because so many depend on natural resources for their food, shelter and income. Micro Level : Global Condition of Nepal :The picture of Nepal is as bleak or even worse than many other developing countries around the world, but it remains little understood. Reviewing the past is important for understanding future climatic changes and developing adaptation and mitigation plans. We intend to unfold the past and offer ideas to carve the path for a sustainable future, global warming research paper.
Past warming-led events in Nepal based on scientific findings and local perceptions collected through surveys are global warming research paper below. Major impacts of warming are outlined and possible implications for human wellbeing are also discussed. From From mean annual maximum temperature in Nepal increased by 0, global warming research paper. Now, average temperature rise is estimated at 0. Precipitation is also becoming unpredictable and more erratic than ever, with more droughts and shorter periods of heavy rainfall.
This is an alarm bell. Every year, diseases and natural calamities caused by such changes claim the lives of several people, the majority being poor women and children who lack the capacity to adapt to change. For instance, Diarrohea kills 28, people annually in Nepal and most of the affected are children below age 5. Floods following ice melting and lake outburst or river overflow also kill several people by adversely affecting water quality from debris carried along with the flood. Between and ,more than people, mostly poor, were killed by floods and landslide related disasters CBS These gases are required for the presence of human life on earth.
However, global warming is happening due to overemittance of these gases. By the region is expected to have a completely ice free summer, or even earlier. This not only increased greenhouse gases but was also responsible for large global warming research paper deaths due to asthma and other respiratory diseases. If these figures do not startle, then it will be extremely difficult to prevent the world from collapsing from global warming.
Many schools, organizations, government bodies etc are making efforts to encourage people to take steps that would prevent them from taking any action that would lead to global warming. The most important consideration however is to feel for the problem and to be fully awakened to the situation. Unless the critical issue of global warming global warming research paper not hit every person on earth, it will be global warming research paper difficult to prevent the world from burning due to global warming in the near future.
Various laws and legislations have been developed in order to protect the environment. Some of the laws and legislations enacted by Nepal government to protect the environment have been discussed below: Concurrently, a unified Consumer Protection Bill has been tabled in Parliament.
Notwithstanding the lack, until recently, of specially designed and unified legal instruments to comprehensively address environmental and consumer protection issues, there are some 69 different Acts which directly or indirectly provide the basis for regulating and enforcing various environmental protection measures, and for safeguarding the interest of general consumers.
Each of the Act is supplemented by corresponding regulations. The Environmental Protection Act EPA as a framework legislation covers the essential aspects related to environmental protection; the provision of authority to establish protected areas; testing facilities; the establishment of a fund; the establishment of the necessary administrative mechanism; the establishment of EPC; penalties for violations of the Act; and the authority to enforce guidelines and standards.
Environmental protection under Nepal's Environmental Protection Act Needed comprehensive rules and regulationsSince a comprehensive legislation, in the form of the Environment Protection Act,already exists, its immediate and effective implementation needs equally comprehensive rules and regulations which specify in clear terms the authority, responsibility and jurisdiction of the various government agencies, global warming research paper, local bodies, private sector and NGOs.
It will also be necessary to decentralize the authority for execution and implementation functions to line agencies so that the Ministry of Population and Environment can concentrate on policy integration, coordination, facilitation and legislation. In view of the present liberal, market-oriented policy of the government, it would also be advisable to introduce economic instruments and market mechanisms for compliance with environmental measures.
Taking into consideration the economic growth and environmental situation of the country, it will be worthwhile exploring some possible policy options and incentive measures. International Environmental LawMany countries have adopted comprehensive environmental laws. Many nations ascribe to and follow, to varying degrees, international agreements regarding environmental issues, global warming research paper.
Pollution does not respect political boundaries, making international global warming research paper an important aspect of environmental law. Numerous legally binding international agreements now encompass a wide variety of issue-areas, from terrestrial, marine and atmospheric pollution through to wildlife and biodiversity protection, global warming research paper. While the bodies that proposed, argued, agreed upon and global warming research paper adopted existing international agreements vary according to each agreement.
Scientists predict an increase in sea levels worldwide due to the melting of two massive ice sheets in Antarctica and Greenland, global warming research paper on the East coast of the U.
However, many nations around the world will experience the effects of rising sea levels, which could displace millions of people, global warming research paper. One nation, the Maldives, is already looking for a new home, thanks to rising sea levels. Similarly, the severity of storms such as hurricanes and cyclones is increasing,research published in nature says that "Scientists have come up with the firmest evidence so far that global warming will significantly increase the intensity of the most extreme storms worldwide.
The maximum wind speeds of the strongest tropical cyclones have increased significantly sinceaccording to research published in Nature this week. And the upward trend, thought to be driven by rising ocean temperatures, is unlikely to stop at any time soon, global warming research paper.

Global Warming is a long-term rise in the average temperature of the Earth’s climate system, an aspect of climate change shown by temperature measurements and by multiple effects of the warming. Most people might think that global warming is caused by human activity; however, environment have caused global warming itself as a result of climate changes, nature disaster, and changes in the For the period through , the literature survey found seven papers suggesting further cooling, 20 neutral, and 44 warming. Even in the early years of the study of climate change, more science studies were discussing concerns about global warming than global cooling. (Figure source: Peterson et topic of global warming, such as the economic, ethical, and social responsibilities which are involved. Global warming is a phenomenon which has been occurring over the past 15, years on Earth. It can be described as a struggle between human progress (in the form of industrialization, population increase, and economic growth) and nature. The process of global warming occurs when greenhouse
