Climate is the weather patterns or weather conditions in a region in general or over a long lasting period. Climate change can be defined as a long term shift in global or regional climate patterns. Many scientific evidences suggest that human activities are contributing to climatic changes but sometimes, the changes caused by mankind are often hidden by natural climate variability (The Free Dictionary, n.d)
There are two parts of investigation that scientists attempt to identify and separate the mankind factors and natural factors. One is detection study in which the scientists measure the temperature changes to gather information and the other one is attribution study in which they find the scientific reason for the unusual changes in climate. Scientists use climate models to analyze the pattern of temperature change and find the characteristic patterns of climate response which is regarded as fingerprint match (Hamburg, 2009).
Conversion of land for forestry and agriculture is considered as one of typical human activities which contribute to carbon dioxide emission. As the world population keeps growing constantly, people need more space for agricultural practices and ho...

- Discuss how economic principles contribute to our understanding of the causes and consequences of climate change. Critically evaluate the performance of UK Climate Change Policy in recent decades and the extent to which the UK Carbon Plan provides a credible framework for achieving a lasting reduction in greenhouse gas emissions. Over the last few decades the awareness of environmental problems have significantly increased worldwide. The scope of the environmental issues has been widen to urgently tackle these ongoing problems.... [tags: Greenhouse gas, Carbon dioxide, Externality]

- Global warming: one of the hottest and most politically charged issues of the 21st century, and for good reason. The potential harms are massive: Ice sheets melting (causing sea levels to rise and a decline of available fresh water), more common droughts and floods, stronger natural disasters and a complete over-haul of our ecosystem (nationalgeographic.com). Combine these factors and add in a few hundred years, we could have a messy situation. We know what might happen if the trend of increasing universal temperatures continues, but nobody can seem to pinpoint the exact reasons as to why this is happening.... [tags: Global Warming Essays]

- “Climatism is the belief that man-made greenhouse gases are destroying earth’s climate” said Steve Goreham, the executive director of the Climate Science Coalition of America and author of the book “The Mad, Mad, Mad World of Climatism: Mankind and Climate Change Mania”. Historically, earth climate has become a major problem after the Industrial Revolution during the 18th and 19th century and it significantly becomes a big concern in the present days. This essay will illustrate the possible root of climate change which is caused by mankind as well as nature.... [tags: Global Warming Essays]

- 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....

- Burning of fossil fuels contribute to a highly carbon dioxide emissions, which causes global warming. Coal has been using as the largest and primary resource of fossil fuel for generating the electricity, heat, and industrial purposes. Due to the high content of carbon dioxide in coal, it produces a high percentage of carbon dioxide emission into the atmosphere more than other fossil fuels, when it is combusted (Biologicaldiversity.org, 2014). By 2012, 41 percent of global electricity is generated by coal-fired power plants and it accounts for 39 percent of U.S electricity, which is equal around 83 percent of greenhouse gas emissions in the United States (Worldcoal.org, 2014)....

- An American vice president, Al Gore, said that while the reason behind dinosaurs’ extinction over 65 million years ago was because of a giant asteroid, the species that are dying out every minute of our lives are not just because of some havocs, but it is US-human (Al Gore, 2006, internet). We are destroying our world indirectly which means we do not just go and kill those entire animals, but what has caused their extinction is due to “Climate Change” that is the result of the Natural Causes and Human Activities....

- The planet Earth goes through cycles in every aspect of its environment from temperature, to water levels, to levels of carbon dioxide in the atmosphere. There has always been a limit to the levels of carbon dioxide in the atmosphere. The Earth is like a human body. If a human does not take care of their body through healthy eating and workouts, they become unhealthy and may have health problems. As with Earth, if Earth takes in more heat than it can let out, or vice versa, there will be global climate changes.... [tags: Global Warming Essays]

- "Ladies and gentlemen, the world's forests need to be seen for what they are—giant global utilities, providing essential public services to humanity on a vast scale." -- Prince Charles on Deforestation Many development institutions and politicians regard population pressure as the major factor causing rainforest destruction. Nobody can deny the serious global problem of population growth. However, the belief that this is the main cause of rainforest loss is used by many governments and businesses to imply that there is little or nothing they can do about the problem of rainforest destruction....

- ... These sub artesian bores have shown that they contain high amounts of salt in the water and contribute to majority of the above ground salinity levels.(5) The concern arises as CSG is using and accessing the same bores that contain these high salinity levels however as previously mentioned CSG extracts vast amounts of water to obtain methane gas. In the Condamine catchment within the Murray darling it was estimated that with the amount of water that CSG extracts from the ground that 588000 tons of salt will be contributed to above ground water levels in a single year as seen in the figure below....

- Over the past decades, the Earth experiences disasters continuously. Many scientists identified them as signs of climate change. The causes of climate change can be divided into two main factors; they are natural events and human activity. “As human beings, we are vulnerable to confusing the unprecedented with the improbable. In our everyday experience, if something has never happened before, we are generally safe in assuming it is not going to happen in the future, but the expectation can kill you and climate change is one of those exceptions”, expressed by the former United States vice president Al Gore (Climate Change Quotation, Internet)....
