Interactions between human and the ecosystem have been operating for millenniums, and are impossible to eliminate, as each depends on the other in order to survive and flourish. However, as modern technology advances, as well as the increase in the world’s population, the need for natural resources begin to rise to an alarming rate which has started to gradually destroy the ecosystem. Recently, there has been an increase of sea levels in region whilst other rain-bounty areas have begun to experience their first droughts. This phenomenon is known as climate change. Climatologists have concluded that human activity has played a major role in contributing to the changes, therefore requiring extreme measures before this phenomenon evolves into a catastrophe. In this essay, we will discuss human activities that contributed to climate change, as well as addressing possible solutions to the phenomenon. 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... ... middle of paper ... ...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 on the international policy agenda primarily because of warnings from scientists. Their forecasts of a potentially dangerous increase in the average global temperature, fortuitously assisted by unusual weather events, have prompted governments to enter into perhaps the most complicated and most significant set of negotiations ever attempted. Key questions - the rapidity of global climate change, its effects on the natural systems on which humans depend, and the options available to lessen or adapt to such change - have energized the scientific and related communities in analyses that are deeply dependent on scientific evidence and research.
From the home to factories, families and industries are reliant on the use of nonrenewable fossil fuels to feed the needs of the everyday human. Fossil fuels are the main source of energy over clean, renewable sources such as the use of wind, solar energy, and water to power our homes, schools, and industries. In fact, about 85% of energy use comes from fossils fuels. The main reason being that using fossil fuels is cheaper than wind and solar energy. “For nearly two centuries, fossil fuels have been the cheapest source of energy” and widely abundant (Marburger, A global framework: international aspects of climate change). However, overtime fossil fuels will disappear due to the lack of time to replenish itself with the human races rapid use of it. Despite its current status of availability, there are many controversial issue in using fossil fuels; the most prominent issue being that it is the cause of rapid climate
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.
How would you like to live in a home that is beginning to fall apart, but only to go on about your day and continue to neglect it until it all comes crashing down? Humans and animals share this beautiful planet that we call home. But this beautiful home of ours is being regularly and increasingly torn apart by our own ignorant actions. These actions of ours have begun to unravel the very world in which we live, causing a self-inflicted crisis known as Global Climate Change. Global Climate Change is a severe dilemma, and it is continuously becoming more evident to the world’s population that climate change is being caused by changes in the reflectivity of earth’s atmosphere and surface, the ever changing variations of energy from the sun reaching the earth, and the daunting increase in greenhouse gasses.
There is no longer any question that our world climate has changed (King, 2004). Over the last 100 years, "temperatures have risen by about 0.6 degrees Celsius and global sea level has risen by about 20cm" (K...
In theory some parts of the world might benefit, from a human point of view, due to global warming. However, at current rates of warming, local ecosystems will collapse and any objective measure of global benefits versus suffering would show much more suffering than benefits gained.
Fossil fuels are an unreliable and unsafe source for worldwide energy. Our common fuels will run out as in: Ethanol, Petroleum, and Oil. Honestly we need those fuels for life, to drive cars, four wheelers, lawn mowers, and tractors, etc. If we did not have those things anymore our ways of living will drastically decrease. People in our society are so use to driving vehicles that if that gets taken away World War III would start. We use lawn mowers to cut our grass, to keep our land in shape and pretty. We also use tractors for multiple things not only to keep big pastures in shape, but also to use for logging. People do logging for a living. Without tractors their job would be very intense.(conserve-energy-future.com)
It is an unquestioned fact that the climate is changing. There is abundant evidence that the world is becoming warmer and warmer. The temperature of the global land average temperature has increased by about 8.5 degrees centigrade from 1880 to 2012 (Karr, et al 406). The one or two degrees increase in temperature can cause dramatic and serious consequences to the earth as well as humans. More extreme weather occurs, such as heat waves and droughts. The Arctic Region is especially sensitive to global climate change. According to the data in recent decades, the temperature in the Arctic has increased by more than 2 degrees centigrade in the recent half century (Przybylak 316). Climate change has led to a series of environmental and ecological negative
The three fossil fuels- coal, crude oil, and gas slowly formed over millions of years. These days, we use fossil fuels to power everything- homes, buildings, cars, computers, lights, etc. However, fossil fuels deposits will run out soon, which is a huge problem. Extracting, transporting, and burning fossil fuels are dangerous. There are also many negative biological and environmental impacts that result from the use of fossil fuels, such as ocean acidification, groundwater contamination, land subsidence, oil spills, and global warming. Therefore, we should be trying to reduce our dependence on fossil fuels and explore alternative energy sources such as wind energy, hydroelectricity, and solar energy instead. Our world depends on fossil fuels, but they can also hurt us. Fossil fuels are both a blessing and a curse.
The end of the ice age was the first sign of the rise of the earth's surface temperature, since the end of the ice age the temperature continues to rise. To this day ice covering Antarctica, Greenland, and in mountain glaciers around the world continue to melt at a rapid pace. There is not only thermal evidence and increased water levels to prove that there is a sigingofact amount of glacial melting, there is photographic evidence of the decrease in volume of ice over the years. The decrease in the volume of the polar ice caps is not the only alarming evidence proving the rapid incline of the earth's surface
Climate change is a long-term alteration in the statistical distribution of weather pattern over periods ranging from decades to millions of years. The world is currently experiencing drastic change in temperature. This change can be felt in the tropical climate areas where the weather is getting hotter and hotter every day. The change in global temperatures and precipitation over time is due to natural variability or to human activity. It is also caused by accumulation of greenhouse effects (Arrhenius, 1896). Should we as humans let this problem worsen? Climate change will affect everything including humans, flora and fauna, and the environment.
The earth is a complex system, which continues to evolve and change. Climate change and global warming are currently popular in the political agenda. But what does “climate” really mean? The difference between weather and climate can be conveyed in a single sentence: “Climate is what you expect; weather is what you get.” Based on research of the geologic record, we know that climate change has happened throughout Earth's history and at present, ever-increasing evidence points to the roles that humans play in altering Earth systems. The Earth and its atmosphere receive heat energy from the sun; the atmospheric heat budget of the Earth depends on the balance between incoming solar radiation and outgoing radiation from the planet; which has been constant over the last few thousand years. However present evidence seems to suggest that the recent increase in temperature has been brought about by pollution of the atmosphere, in particular the release of huge amounts of carbon dioxide, mostly through Anthropogenic Forcing (human activity) and other various internal and external factors.

Replacing fossil fuels and using renewable resources can make a huge difference in earth’s environment. The Renewable energies can be reused thusnot only that but their always never going to end because you’ve got the wind the sun wind water that fuel these energies.They make earth’s atmosphere cleaner and the fossils fuels are nonrenewable in which they have limited quantities.Fossil fuels take millions to hundred millions of years to form. The demand of renewable resources is high in demand as were using up the fossils fuels. Soon later on in the future fossil fuels will become scarce and very expensive. As people around the world are using up fossil fuels, renewable energy resources are going to replace fossil fuels in the future.
With the advent of scientific and technological innovations, human beings have made tremendous industrial and economic successes. Nevertheless, climate change, characterized by the earth heated by from over-emitted green house gases, has been recognized as one of the most serious but inevitable consequences of human development. According to Crowley (2000), the combination of a unique level of temperature increase in the late 20th century and improved constraints on the role of natural variability provides further evidence that the greenhouse effect has already established itself above the level of natural variability in the climate system. As a result, people have recently been suffering from gradually unpredictable weather change, especially inclement and extreme weather conditions.
Fuels like coal, and oil that once were a fine innovation in creating energy are now rapidly deleting and one day will be gone forever; energy that won’t last is often referred to as non-renewable energy. Besides being set up to fail and become inefficient in the future, fossil fuel energy is not clean to use and poses several environmental complications. Coal, for instance is “the dirtiest of all fossil fuels. Coal combustion not only produces sulfur oxides and nitrogen oxides that contribute to acid rain and snow, it generates millions of tons of particulates that cause asthma and other respiratory diseases.” As with all usage of fossil fuels, it creates enormous amounts of carbon dioxide, which contributes to greenhouse gas. Not only are fossil fuels dirty, they also pose as a security risk and unforgiving on the American wallet. (Saini)
