Recommended: The role of humans in climate change

Nowadays, climate change is became a major global issue which are affecting our life such as global warming ,mean sea level changing and more extreme weather events etc .According to the research of Intergovernmental Panel on Climate Change 2007 ,it showed that the global mean temperature rose by 0.74 °C during the hundred year period from 1906 to 2005. Between 1956 and 2005,the rising rate was 0.13°C per decade in this 50 years , nearly twice the rate in the past 100 years. Eight (2010, 2005, 2003, 2007, 2006, 2009, 2012, 2004) of the last ten years (from 2003 to 2012) rank among the 10 warmest years on record. It seems that climate change is potentially affecting our life.In fact,human activities and natural effect are the causes of climate change.Generally,most of the scientists and government agree that human activities is the main causes of climate change rather than natural causes.Therefore,this essay is going to discuss why human activities change the climate more seriously than natural effect.Afterward,I will also present some possible solution to reduce the climate change.

Greenhouse gas is a type of gas in atmosphere which absorb and emit radiation.Certain gases will block by atmosphere when escaping from the Earth and keeping the Earth warm.Therefore,this process is called Greenhouse Effect .The primary gases in the Earth are water vapour , carbon dioxide , methane , nitrous oxide and chlorofluorocarbons etc.However,human activities are changing the natural greenhouse.According to the IPCC Fourth Assessment Report issued on 2 February 2007 , it can be observed that there was a significant increase in globally averaged temperatures since the mid-20th century .One of the reason is the industrial revolution ,the develop...

...rgy.If we save water,it potentially reduce the greenhouse gas emission.

In this essay i have discussed the reason of why human activity is the main cause of climate change rather than natural cause ,the effect of climate change and presented the possible solutions.Besides,the main cause of climate change is human activities such as a large amount of greenhouse gas emission and over-logging.These activities expand the greenhouse effect and rise the global temperature.Moreover,climate change affect the sea level,the amount of extreme weather event and the acidification of ocean.To solve these problem,international cooperation is the most important solution and people can also reduce the greenhouse gas by saving energy.Overall,I think the problem of climate change will be improved in the future since more and more people have rose their awareness of environment issues.

    Global warming and global climate change is the study of future increases of temperature across the globe. Studying climate change refers to how the over- all climate will change such as the dry places getting dryer and the wet places getting wetter. Global climate is dependent on “the greenhouse effect a natural process that helps regulate temperature” (Easterling and Karl). In the past few centuries humans have had a monumental effect on increasing of greenhouse gases in the atmosphere. Climate change is result of the increase amount of the greenhouse gasses in the atmosphere such as methane, carbon dioxide, water vapor, nitrous oxide, and ozone. “Global temperature has rose approximately 1.4 degrees Fahrenheit over

    The climate on the Earth is changing. Ice age is interleaved with the global warming. In the present age, the temperature of the Earth's climate system continue rapidly increase and it leads to global warming. Global warming is the process of gradual growth of average annual temperature of the atmosphere of the Earth and World ocean. The average temperature on the Earth was increased by 0.6C. There are various reasons of global warming, such as human activities, natural events, increasing of gases, such as carbon dioxide in atmosphere and solar activity (Global warming). Nearly 200 countries have signed Kyoto Protocol and they must reduce four greenhouse gases, in order to struggle with global warming. There are several perspectives about effects of global warming on environment. In this essay will be considered the impacts and consequences of global warming . In the process, it will be clarified that there are positive and negative impacts of global warming.

  • Air Pollution Essay: Greenhouse Gases and Climate Change

    1498 Words  | 3 Pages

    Air pollution and greenhouse gases are the reason for the planet as it is today; the reason why we see campaigns flooding the media informing us to ‘switch off’, ‘save the planet’ and ‘turn down the heat’ and the reason why the government is trying to develop a successful scheme, such as the carbon tax scheme, to reduce air pollution caused by major industries. Air pollution and greenhouse gases are the two immediate causes of global warming and climate change. Air pollution occurs when chemicals or particulate matter enter the atmosphere. They can cause damage to living organisms on the planet, as well as destruction to the natural and synthetic environment (Energy Environment.net 2008). Greenhouse gases are gases in the atmosphere that absorb infrared radiation emitted from the earth. They trap infrared radiation in the form of heat, and hence contribute to global warming. Anthropogenic greenhouse gases are a direct result of air pollution. They are the physical gases emitted that cause air pollution. Naturally occurring greenhouse gases also have an influence on the earth’s atmosphere, though it is not as conspicuous as anthropogenic causes. Together, air pollution and greenhouse gases are intensifying climate change and global warming on a world-wide basis.

    Many climate scientists, researchers, and environmentalists are expressing concerns about shifts in the overall climate of the earth. It is believed that a dramatically dangerous warming is taking place in the overall global climate, a problem that is referred to as "global warming”. Global warming is the observed century-scale rise in the average temperature of Earth’s climate system. This temperature rise is due to the damaging effects of deforestation and the burning of fossil fuels. It is our responsibility to preserve our planet and our way of living but in order to do that we need to act now. If we continue to destroy the planet with no regard as to how serious this matter is there could be several negative effects to us as human being and other living thing on Earth. This is why global warming is truly a global issue and needs to be tackled collectively. We must to act now in order to reduce the dangerous levels of carbon dioxide emissions and we must to work together.

    A greenhouse gas is “a gas such as carbon dioxide, ozone, or water vapor that contributes to the warming of the Earth’s atmosphere by reflecting radiation from the Earth’s surface” . “The naturally occurring greenhouse effect is necessary to provide a warm atmosphere conducive to life on Earth“, but because human activities increase the greenhouse gases the green house effect is badly increasing causing the temperatures to rise . Greenhouse effect is the “warming of the Earth’s surface as a result of atmospheric pollution by gases” . Because global warming today is not only caused by coal, but by oil , methane , and other greenhouse gases, consumers today should decrease the use of greenhouse emitting things and look for more efficient options in order to prevent and possibly reverse global warming. Global warming affects everything from the ocean, plants, and animals because of the increase in temperature.

    The greenhouse gases are a group of components that are able to trap heat on the atmosphere. They are made up of three or more atoms that enable them to trap and re-emit heat. These gases are the main cause of greenhouse effect. Human activities and natural processes increase the amount of greenhouse gases and that stimulates the greenhouse effect which in turn creates the global warming and consequently changes in climate. The greenhouse gases hold potential to change climate of the earth by affecting the radiation balance of the atmosphere alternatively. When chemically active gases interact with greenhouse gases directly or indirectly, they lead to a change in concentration of greenhouse gases.

    In the modern era, climate change is a variation of weather over a long period of time, and it is the most important and controversial global issue. It is arguable in different positions, especially on science, culture, and politics. These three fields all cause a lot of latent concerns. The science of climate change brings out several harmful phenomenon, such as global warming. With respect to the climate change, the culture of humanity may be changed because the changing climate is the most important key factor of forming today’s human societies. Instead, climate change is now a political issue, which will affect the public attitudes directly. In other words, it means the government tends to review and provide latest information in order to adapt and retard the climate change.

  • The Effects of Squandering Natural Resources

    Climate change is not an unnatural occurrence for the fluctuating planet. According to scientists, Earth has experienced numerous epochs over the course of millions of years in which the climate oscillates between extreme hot and cold. For instance, during a period called Paleocene-Eocene Thermal Maximum, the average temperature of the Earth increased by 11ºF. Since the late of 18th century, immediately after the Industrial Revolution, the average temperature of the Earth spiked exponentially. While few argue that this change is ordinary, the available data and scrupulous observations show that human activities that release greenhouse gases can be correlated with the climate change that is happening. Because the change poses dangerous threats to the world, a great deal of countries, in all continents, have put efforts to mitigate it. Latin American countries and China are just a few countries that are involved in this movement. The misuse of natural resources, one of the leading causes of climate change, induces severe economic crisis. In order to prevent such an event, using raw materials effectively should be the top priority of all countries.

    Climate changes occur in our earth's atmosphere due to a buildup of greenhouse gases. Greenhouse gases can occur naturally as well as a result of human activities. The greenhouse gases are carbon dioxide, methane, and nitrous oxide. “Carbon dioxide is released into the atmosphere when solid waste, fossil fuels, and wood are burned.” (2) The gases help to warm the surface of the Earth. Each greenhouse gas absorbs heat differently. If natural gases did not occur, the temperature of the earth would be considerably cooler. “Problems can occur when higher concentrations of greenhouse gases are present in our atmosphere because they have enhanced our earth's heat trapping capability.” (3)

    Global warming is the gradual rise in temperature and oceans due to recent human activity. This is created by the production of too much carbon dioxide that is released into the earth’s atmosphere. The carbon dioxide, also known as a greenhouse gas, remains in the air trapping heat and gradually warming the planet. Other greenhouse gases such as: methane, nitrous oxide, and water vapor also contribute to this slow warming. According to Live Science, The state of these gases being trapped is called the greenhouse effect, which is one of the leading causes of global warming (Lallanillia). All the gases are created differently and have different effects on the earth. As for some greenhouse gases can be in the atmosphere for a short amount of time, other gases can remain in the atmosphere for thousands of
