According to the IPCC, climate change is defined as variations of climate conditions and its fluctuations existing on a long term particularly decades or longer (IPCC's Glossary, 2006).The alteration varies from changes in temperature, humidity, precipitation to the rise and fall sea level, or severe changes in landscape. Since the 1800s, the earth has had variant changes in global hemispheric temperature which mostly depicts the decrease of temperature. However, at the start of 1970s, temperature begins to rise up simultaneously in all regions for over roughly a century, an event that was unseen before (Figure 1.1) (Jones, 2011). Furthermore, as earth’s temperature is getting warmer, the ice in the Arctic Ocean began to melt in the warming temperature. The liquidation of the Arctic Ice has been occurring since the 1970s, however in Septem...

...dition, fossil fuels not only unleash carbon dioxide into the atmosphere, but also is harmful to human when exposed for a long period of time, new energy resources would be needed to replace it such as, wind turbans, biomass energy, wind energy, solar energy, geothermal energy, and hydroelectric energy (Alternative Energy).
In conclusion, evidence has pointed out that weather patterns, and climate conditions are shifting at a rapid rate that has never happened before. As the environment worsens, drastic measures must be taken to prevent it before the earth’s ecosystem will be permanently altered to a vast and hazardous environment that is inhabitable. Interaction between human activity and natural environment is inevitable, as it has always been in harmony until recent years. Regulations must be set to ensure that one party does not overpower and destroy the other.

- Climate change is one of the biggest concerns for all nations across the globe over centuries. Climate shift refers to changes in patterns of weather which can be indicated through global warming, natural disasters and rise in sea level. There is a group of people, climate change skeptics, argue that climate change is not the result of human activity, meaning that it is naturally occurred. According to Slaght, this refers to internal factors which are the interaction between the atmosphere and ocean, and external factor, such as solar energy variations and volcanic eruption (John Slaght, 2009)....

- What is deforestation, degradation and climate change Deforestation: It implies the long term permanent loss of forest cover and implies transformation into another land use. Such a loss can only be caused and maintained by a continued human-induced or natural perturbation (FAO, 2001). Forest degradation: The long term reduction of the overall potential supply of benefits from the forest, which includes carbon, wood, biodiversity and other goods and services (FAO, 2003). Climate change: It refers to a statistically significant variation in either the mean state of the climate or in its variability, persisting for an extended period (typically decades or longer)....

- As humans approach a future of uncertainty, enigmas are unraveling all around the globe. Climate change is one of the most influential concerns to humankinds, since there seems to be a dramatic change in the Earth’s climate such as noticeable increase in temperature.According to United Nations Framework Convention on Climate Change (UNFCCC), climate change may be defined as the change in atmosphere that results from indirect or direct contribution to the climate by humans in which affect the modification of the Earth’s atmosphere and additionally may introduce to the inconsistency of the natural climate ("United nations framework," 1992)....

- Introduction International tourism can now be recognised as one of the biggest contributing sectors for many countries’ GDP. Moreover, it has transformed them in many aspects such as economic, socio-culture, and environment. International tourism involves activity of inbound and outbound tourist of a country and resident or non-resident visitors within the country (World Tourism Organisation 2014). The World Tourism Organisation has predicted the growth of tourism activities to increase by an average 3.3% up to the year 2030.... [tags: climate change, exploitation, damage]

- "Even the best democracies agree that when a major war approaches, democracy must be put on hold for the time being. I have a feeling that climate change may be an issue as severe as a war. It may be necessary to put democracy on hold for a while." - James Lovelock (Hickman, 2010) Climate change is a long-term change in the Earth’s climate, mostly due to the increase in the average atmospheric temperature (global warming)....

- When discussing the topic of climate change, it is essential to begin with a brief definition of climate change to know exactly what it is. Anup Shah of globalissues.org defines climate change as “an increase in average global temperatures…caused by the increase in greenhouse gasses such as Carbon Dioxide, or CO2” (Shah, 2014). This process, of course, is global warming which, in turn, leads to climate change. Although climate change is considered one of the most significant threats facing the world today, there are many groups doing what they can to assist in slowing the climate change process or potentially halt it all together....

- Climate Change Impacts on Biodiversity The link between climate change and biodiversity loss has long been established. Although throughout Earth’s history the climate has always changed with ecosystems and species coming and going were able to adapt. Rapid climate change affects the ecosystems and species ability to adapt and so biodiversity loss increases. Climate change has many environmental impacts on biodiversity, projected future changes are likely to result in changes in the distribution of species and ecosystems, and overall biodiversity loss....

- 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]

- In recent years, global warming is a topic that has received much attention. It’s is a gradual increase in the overall temperature of the earth's atmosphere generally attributed to the greenhouse effect caused by increased levels of carbon dioxide and other pollutants, which also known as the green house effect. Global warming can negatively affect the earth's delicate ecosystems. It has been linked to dangerous new weather patterns, the extinction of plant and animal species and so many others bad effects.... [tags: environmental issues, greenhouse effect]
