Global warming, also referred to as climate change which means a current increase in temperature of the earth’s surface as well as it’s atmosphere due to rising levels of greenhouse gases. It is a big issue of the atmosphere on the earth. It is caused by the human as well as by natural events. Human is the causes for emission of greenhouse gases such as methane, nitrous oxide, and carbon dioxide. Over the past 100 years, the earth has warmed by about 1°F.
Scientists also predicted that the average temperature could increase between 1.4 to 5.8°C by the year 2100. Greenhouse gases can cause global warming. Based on Collins Dictionary, The greenhouse effect is the problem caused by increased quantities of gases such as carbon dioxide in the air. These gases trap the heat from the sun, and cause a gradual rise in the temperature of the Earth's atmosphere. Gases such as carbon dioxide, sulphur dioxide, methane, nitrous oxide, halocarbons and so on, built up in the atmosphere due to increased use of energy and the expansion of global economy in the 20th century.
Natural events and human activities are believed to be contributing to an increase in average global temperatures. This is caused primarily by increases in “greenhouse” gases such as Carbon Dioxide (CO2) and that further leads to the greenhouse effect (appendix 2, image 0.1) Global warming has raised the average temperature of the world, because of this
Causes of Global Warming Scientists trust that before the century's over, the temperature of the earth’s will turn out to be much hotter than it is temperature now. By 2100, the normal worldwide temperature will be around 5.8 degrees hotter, if people proceed with their present CO2 produce. Global warming in fact is an enormous natural issue and social problem everywhere throughout the world. Therefore, it has turned out to be exceptionally important to increase awareness about it among the people on the earth. An unnatural weather change is the trudging warming of the earth outer surface, due to the constantly increasing temperature of the climate that happen because of some common and human made causes.
What is global warming? Global warming is defined as “ an increase in the earth 's average atmospheric temperature that causes corresponding changes in climate, and that may result from the greenhouse effect" (“Global warming”). Natural events and human that causes global warming are believed to be factors to increase in average temperatures. This essay looks into the growing problem of global warming and suggests reasonable solutions to it. It also evaluates the effectiveness of these solutions.
Global warming is a big problem that we have to face nowadays. If you search Google for the word “global warming’, you will get over 70 million pages of results. The subject has certainly drawn a lot of attention. And now I will talk more about “what is global warming” , the cause and the effects it has on the earth and also some possible solutions for this problem. The first question “What is Global Warming?” Global warming is the gradual increase of the temperature of earth 's atmosphere and oceans.
Characteristic of global warming and its cause Global warming is an issue defined as increased ocean temperature. In the strict sense, it is applied for a climate changes between 20. and 21. century. In a fact global warming affects ferocious fire, drought, rising seas and decreasing glaciers, storms, floods and economy. An issue is a velocity of the concentration of the carbon dioxide in the atmosphere. This initiates rise of the temperature.
Climate change can also be defined as a change in global temperatures for extended durations (Maqbool, 2013). The health and survival of humans and ecosystems on the Earth depends on the world’s climate (McMichael, 2003). King (2004) believed that climate change is a threat to human civilisation (Gill et al., 2009, p.324). Global warming, its consequences and human intervention The Earth’s surface temperature worldwide has risen by nearly 0.50C since 1975 (Hansen et al., 1999; Jones et al., 1999; as cited in Hansen et al., 2000, p.9875); and this increase has been attributed to the rising human activities which release GHGs into the Earth’s atmosphere (Hansen et al., 2000). Heating up of the Earth’s surface adds more vapour to the atmosphere which further builds up increases the moisture levels in storms (Meehl et al., 2000, p.433).
Climate change may potentially be the biggest global health threat in the 21st century. Our response requires a new public health movement that consists of multi-disciplinary and multi-sectoral solutions that leads to coordinated thinking and action across governments all over the world, international agencies, NGOs, and academic institutions. Warmer temperatures will lead to even hotter days and even more frequent and longer upcoming heat waves. According to the U.S Global Change Research Program these changes will lead to an increase in heat-related deaths all over the world, reaching as
INFLUENCE OF GLOBAL WARMING ON INDIAN CLIMATE Abstract:- Global warming has come across as a monumental factor in the world. we can say the wide-scale use of non-renewable energy resources has exponentially enhanced the levels of pollution. This has upended environmental stability and started rising the global temperature (the surface temperature has raised by almost .5°C in the last 26 years. This has output in the increasing rate of melting of the ice cap on mountains regions and thus the rise of level of ocean. This also has a direct affect on rains and weather fluctuations day by day.
