Many people might think that anthropogenic influences are the only cause to climate change on Earth. However, there are many factors which are unnoticed by the human population that contributes to this crucial issue. For example, the most common phenomenon is global warming which is a factor to the progression of climate change over time. (1) This means that climate change has not just happened for a year, but throughout the Earth`s climatic history. In the modern era, this has been a controversial issue at which people only think that human activity is a primary cause of climate change, but there is a consensus view of this problem. There are 97.1 percent of the scientists who believe that climate change trends are caused by human effects. (10) This means that human actions such as deforestation, burning of fossil fuels, and growing population results in an increase of greenhouse gases such as CO₂ in the atmosphere to contribute to the greenhouse effect. (4, 5) Nevertheless, there are many natural causes such as volcanic eruptions to cause global cooling, solar irradiance which affected climate in the past and ocean currents which affects the exchange of gases going in and out the atmosphere. (2, 3) To begin, a cause of climate change due to human effect is deforestation and using it for land purposes and agriculture. One of the effects is that the water cycle is disrupted due to the loss of trees which moves water vapour up to the atmosphere. (6, 9) Also, trees absorb the greenhouse gases so without it there is an increase amount of CO₂ in the atmosphere. (6) According to the IPCC, based on the Edgar Databases in 2004, the result of deforestation caused 7-16 percent of the total greenhouse gas emissions. (7)It is because the e... ... middle of paper ... ...aphic%20trends%20matter%20to%20climate%20change.pdf 15) http://www.ipcc.ch/publications_and_data/ar4/syr/en/mains3.html 16) http://www.ipcc.ch/ipccreports/far/wg_I/ipcc_far_wg_I_chapter_01.pdf 17) http://eprints.usq.edu.au/2530/1/climate_justice_campaigns_and_environmental_refugees.pdf 18) http://volcanoes.usgs.gov/hazards/gas/climate.php 19) http://climate.envsci.rutgers.edu/pdf/ROG2000.pdf 20) http://climate.nasa.gov/causes 21) http://www.atmos-chem-phys.net/13/3945/2013/acp-13-3945-2013.pdf 22) http://earthobservatory.nasa.gov/Features/SORCE/sorce_03.php 23) http://www.ipcc.ch/publications_and_data/ar4/syr/en/spms1.html 24) http://www.ipcc.ch/publications_and_data/ar4/syr/en/spms3.html 25) http://www.pfeg.noaa.gov/research/climatemarine/cmfoceanatm/cmfoceanatm2.html 26) http://www.neaq.org/conservation_and_research/climate_change/climate_change_and_the_oceans.php
Mankind’s industrialization of the world has caused a drastic increase in temperature. This rise in temperature is caused by solar radiation remaining in our atmosphere because of gases produced by humans through the burning of fossil fuels, land clearing, agriculture, and other human activities. These gases block the radiation from escaping into space therefore warming our planet. The result is raising of ocean levels, extinction of species and threatening of children’s health because of disease and less freshwater to drink. While many view climate change to be a more natural occurrence than others do, scientists have proven the average temperature rise of the Earth between 0.4 and 0.8 °C over the last 100 years.
Climate change is a major issue that is only going to get worse. Climate change is a change in global or regional climate patterns. It has become more apparent since the mid to late 20th century onwards and is attributed largely to the increased levels of atmospheric carbon dioxide produced by the use of fossil fuels. Climate change has been an important issue for decades that has effects on the environment and people of the world with the end result potentially being catastrophic. Although many believe that prolific use of fossil fuels is the direct cause of climate change, there are many more underlying causes including population expansion as well as irresponsible consumption of natural resources that have
The Earth's climate has changed significantly throughout history. In the last 700,000 years there have been seven cycles of glacial advance and retreat. With the abrupt end of the last ice age approximately 7,000 years ago the beginning of the modern climate era was born. In the last century the global sea level has risen 17cm. All three major global surface temperature reconstructions show that Earth has warmed since 1880. Most of this warming has occurred since the 1970s, with the 20 warmest years, having occurred since 1981 and with all 10 of the warmest years occurring in the past 12 years. There is no denying global warming. Once considered a conspiracy theory by the world’s leading governments, industries and populations; global warming
There are so many factors in today’s growing population and its action that contributes to the environment. With the rise in population there is also increase in the needs and demands resulting in more production of food and assets. Most of the actions of human lead to increased environment risks which in return will only effect the livings of this planet. Currently mostly all individuals have at least one form of vehicle for transportation. There is increased industrialization and requires a lot of energy which comes from fossil fuels as the need for oil increases to fuel large amounts of humans daily work and chores. The climate change is no mystery, it is known to be cause of various human actions trying to satisfy their needs while putting
The earth is changing in many ways. Some of the change can be explained by natural occurrences, but others are related to humans. In this paper I will be showing evidence that relates climate change to humans. First of all what is climate change? Next what is the impact of carbon dioxide have to do with the warming the earth and how do we impact the carbon dioxide levels? Finally, how can we positively impact the fight against climate change?
“In the last three decades, the United States has had an average of 80% consumption of fossil fuels such as coal, gas and oil; all of which contribute to the emission of greenhouse gases” (Josef). All over the world, climate is varied; however, that is not the problem. The problem is that our climate and weather patterns are changing and leaving disaster and catastrophe in its wake. The common question of debate is whether humans are the main cause of this climate change, if it is solely a natural occurrence, and what can we do about it? “Climate change refers to any significant change in the measures of climate lasting for an extended period of time. In other words, climate change includes major changes in temperature, precipitation, or wind
Farmers cleared away the trees for farm animals to graze which means deforestation is caused by growth. Forests assume a huge role in the carbon cycle on our planet. When forests are slashed down, not only does carbon absorption cease, but also the carbon which was stored in the burned trees is released into the atmosphere as CO2. Small crops for instance plants and agricultural crops also draw in carbon dioxide and release oxygen, however forests store up to 100 times more carbon than agricultural fields of the same zone. “It is estimated that more than 1.5 billion tons of carbon dioxide are released to the atmosphere due to deforestation and over 30 million acres of forests and woods are lost every year” Conserve Energy Future
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.
Throughout history climates have drastically changed. There have been shifts from warm climates to the Ice Ages (Cunningham & Cunningham, 2009, p.204). Evidence suggests there have been at least a dozen abrupt climate changes throughout the history of the earth. There are a few suspected reasons for these past climate changes. One reason may be that asteroids hitting the earth and volcanic eruptions caused some of them. A further assumption is that 22-year solar magnetic cycles and 11-year sunspot cycles played a part in the changes. A further possibility is that a regular shifting in the angle of the moon orbiting earth causing changing tides and atmospheric circulation affects the global climate (Cunningham & Cunningham, 2009, p.205). Scientific studies suggest that all these played a role in past global warming and cooling periods. Today, however, there is a lot of conflict on whether humans are causing a global warming that could be disastrous to humans and all species of plants and animals on this earth. This paper will first explain the greenhouse effect, then take a look at both sides argument, and, finally, analyze the effect of global warming on world-wide sustainability
The article “an introduction to climate change” describes in detail about the causes of climate change, and its potential effect on earth. According to this article, the global warming is due to the accumulation of carbon dioxide and other pollutants formed from burning fossil fuels that accumulate on earth’s atmosphere so that light rays are reflected back to the earth surface causing the atmospheric air to heat up. In addition, the article also gives some relevant solutions to global warming such as reducing air pollution and use of “clean energy.”
One of the major issues in today’s society is Global warming. It is one of many kinds of climate that the Earth goes through. The primary cause of global warming is the human expansion of the greenhouse effect. Greenhouse gases keep the earth warm through a process called greenhouse effect. Greenhouse gases like Carbon dioxide trap heat from the atmosphere and maintain the soil warm. Without greenhouse gases, our planet would be too cold. However, people are adding extra greenhouse gases when they’re driving, using electricity, and in a factory. A lot of energy comes from fossil fuels. According to Environmental Protection Agency, the earth’s temperature has increased by 0.8 degree Celsius over the past century. More than half of this grew
The world as we know it is, it is changing in all aspects like rapid advancement in technology and science factors which make the world climate to change. Climate change thus means the variation of global weather conditions. Climate change is the seasonal changes for a long period of time in the world. These climate patterns play an important role in shaping natural ecosystems, and the human economies and cultures that depend on them. For example, the changes in climate can affect how people, plants and animal live, such as food production and health risks. As the earth's climate is dynamic and always changing through a natural cycle, but most recently the scientists have recorded that the earth climatic changes are rapid, unpredictable and not following the natural cycle of global climatic changes of
As we approach the future we are faced with many global problems. Most of these problems arise because we have caused them ourselves. We need to face these problems and find a solution. Global warming, although most often overlooked in importance, is a crucial problem of the future directly related to human activities. Global warming is caused by gases humans release into the atmosphere called anthropogenic gases and by deforestation. Anthropogenic gases include carbon dioxide, methane, chlorofluorocarbons (CFCs), hydrofl...
Throughout the years, climate change has become a topic that people are getting more concerned about as the years go by. Climate change has an effect on the temperature around the world which cause nature to change drastically. Cars, airplanes, coal and other man-made things are considered to enemies to climate change. Although it is a theory, other people think that climate change is something that is occurring naturally by nature. Mankind has been accused of causing different amounts of damage to the world in different ways. Humans ca/ sxsxxxxxxxxxxxssx;2nnot predict what nature has planned for us so we cannot jump to conclusions on the way nature works. Climate change could be affected by something on earth or may not, but it is yet to be
If nothing is done about the reduction of the carbon dioxide in atmosphere, at least about the human contribution, our planet will be impact greatly. According to “Amazonian Deforestation: Impact of Global Warming on the Energy Balance and Climate”, “The effect of the regional changes in CO2 and in the anthropogenic greenhouse gases predicted for 2100 together with that caused by tropical deforestation... It can be seen that the higher impact on the energy balance is caused by the degradation of land. When the increase in greenhouse gases is taken into account together with the effect of deforestation, the changes are reduced, except in the case of the temperature. This is because of the increase in the thermal-infrared radiation flux emitted by the atmosphere toward the surface. The inclusion of the greenhouse gases leads to a reduction in the decrease of the specific humidity or even an increase in the specific humidity…” Deforestation and climate change can be perceived to be a spiteful cycle. Trees absorb water from the land and release it into the atmosphere through leaves. When forests are cleared as a result of human activities, water from the ground is not released into the atmosphere therefore, making the climate much drier. This implies that deforestation reduces the content of ground water, soil water as well as the atmospheric moisture. Trees are the major sources of water and with their removal; the natural water cycle is disrupted, leading to far reaching effects such as droughts. Furthermore, Deforestation leads to global warming due to increased presence of greenhouse gases in the earth’s atmosphere. Forests in reality infuse up carbon dioxide gas and therefore, offsetting the levels of carbon
