Global warming and climate change is not region-specific. It spreads all over the world. Climate change occurs when atmospheric temperature increases a lot which in turn causes many different changes to earth. According to Camelia & Răzvan (n.d), the scientists in different fields consider climate changes as a global challenge which can get irreversible results. Since the revolution of the industry, human activities was increasing day by day, during this period, cultivated land, natural resources, forest resources and various raw material is breaking up by human, so as result of that, a lot of greenhouse gases was released and this lead to global warming (Huang & Li, 2015).
The country of Cambodia faces a grave issue regarding Climate change and the global economy. According to world bank data for the past 16 years, the level of CO2 emissions measured in metric tons per capita have been growing exponentially since the year of 2002. In 2002 the level of carbon emission was.175 and in as recent as 2014 has risen to .438. The continuing rise of carbon emission continues to have extremely harmful effects on not only the environment but the global economy as a whole. The rise of carbon emissions causes temperatures rises adding to the current crisis of global warming which threatens the economic prosperity of Cambodia.
Global warming is rapidly tuning into a strong concern for the citizens of the world. Science believes that the production of greenhouse gases is having a large heating effect on the atmosphere, and this could be very dangerous for human life and the environment. There are many causes of the global warming, some are natural causes and some are human made causes. Unfortunately, humans produce a lot of greenhouse gases through cars, landfills, and livestock cultivation. Deforestation and industrial emissions result to an of increase greenhouse gases around the Earth’s atmosphere.
Risks for infrastructure, risks for ecosystems, risks for fresh water resources and food production, but only steps to build resilient societies can reduce these risks. A few impacts global warming has on the environment are- 1. Physical- It causes an increase in the global mean temperature relative to the pre-industrial levels. Some other effects include global mean sea level rise and ocean acidification causing floods to coastal areas and affecting marine life. Global warming would be irreversible for several millennia.
The most abundant greenhouse gas, but importantly, it acts as a feedback to the climate. Water vapour increases as the earth’s atmosphere warms , but so does the possibility of clouds and precipitation , making these some of the most important feedback mechanisms to the greenhouse effect. Carbon dioxide. A minor but very important component of the atmosphere , carbon dioxide is released through natural processes such as respiration and volcano eruptions and through human activities such as deforestation, land use changes, and burning of fossil fuels. Humans have increased atmospheric carbon dioxide concentration since the industrial revolution began.
Evidence to support that humans are the main reason for global warming is in the book “Global Warming and the Political Ecology of Health” when the text states “The sheer volume of mounting data of diverse sorts has convinced most climate scientists that the global warming, that it is increasingly threatening to human life and well-being, and that it is largely the result of human or anthropogenic activities, particularly since the Industrial Revolution” (Baer/Singer, 3). This means that human ‘activities’ are causing global temperatures to rise, along with the burning of fossil fuels, pollutants in the air, and power/transportation. Most people nowadays have a high carbon footprint that collectively contributes greatly to rising temperatures. To support this,in the book “Global Warming and the Political Ecology of Health”, the authors site from Dessler and Parson, saying that “Many aspects of human society and well-being- where we live, how we build, how we move around, how we earn our livings, what we do for recreation- still depend on a relatively benign reduced and obscured in modern industrial societies by their wealth and technology”(Baer/Singer, 3). This can support the claim that humans are the main cause for global warming temperatures to rise dramatically in the past years.
Basically, global warming is the increase of the world temperature in air and oceans since the mid-20th century (Haldar, 2011). Due to the changes, it increases the global warming that might affect the livelihoods, public health, food security and water availability. Even though industrial activities raise the standard of living, but it increased the atmospheric concentration of GHGs and causes the global temperature to rise. “Earth’s warming has continued due to a process commonly referred to as global warming” (Farrar, 2008, p.7). If the temperature kept rising, it then affects the maritime species, humans can die, and as well as it can disrupt the
There are some specific waste and agricultural management practices that increase the burden on earth by releasing other global warming gases. These other gases include nitrous oxide and methane. Scientists claim that 95% of global warming is caused by the increasing concentration of the greenhouse gases and other activities made by humans. There are many causes of global warming coal burning, car and vehicles and methane gas.
Abstract As there has been a tremendous rise of atmospheric greenhouse gases, there is a threat to the climate which in turn shows the effect on the living creatures. To overcome these problems, some scientists these days are finding ways to scrub the key pollutant, carbon dioxide (CO2), right out of the air. The increase in atmospheric carbon dioxide has attracted international attention due to its impact on global climate. Countries below poverty line release much less atmospheric carbon compared to richer countries in the terms of industrial emissions. The Kyoto protocol was thus established to prevent further increase in atmospheric CO2.
Many scientists believe that our production of carbon dioxide and other greenhouse gases is having a heat effect on the atmosphere and this could be dangerous for the environment and human life (Hansen, 2011). This article will examine the causes of global warming, its impacts and the remedies we can do to combat global warming. Many problems could result from global warming. Increase in average temperatures could lead to ice melting in both polar ice caps and mountain glaciers. Global warming also bring extreme weather events, causes sea level to rise, increases ocean acidification and causes lakes and oceans to warm rapidly than surrounding environment.
