Climate Change And Its Effect On Our Ecosystem Essay

In the last 100 years, the amount of greenhouse gases in the atmosphere has increased, causing the Earth to warm by an average of 0.6 degrees celsius, largely a result of burning fossil fuels for energy, transportation, and land use changes increased for food production. The basic science is straightforward and climate researchers have shown that gases such as carbon dioxide, methane and others can trap heat in the Earth’s atmosphere, causing a phenomenon known as the greenhouse effect. Human activities such as industry, transport, energy generation and deforestation all produce these greenhouse gases. In the last 20 years, concern has grown that global warming is inevitable and now considered most probably caused by man-made increases in

Climate change is classified by many different events and reactions that are happening. The first is that the earth’s atmosphere is trapping more heat. “The warming of Earth's climate, due mostly to increased trapping of heat by gases in the atmosphere, often is termed the greenhouse effect. Some degree of greenhouse effect is natural and normal” (Lerner 3). Some percent of greenhouse gases are produced naturally but a majority of the gases are being produced by humans. ”Most scientists agree that this warming trend is the result of loading the atmosphere with carbon dioxide and other heat-trapping gases” (Freedman 2). The atmosphere is being loaded with carbon dioxide and other harmful gases and this is making the atmosphere trap more heat. Changes in air temperature is another factor of climate change. “The greenhouse effect has been extremely important to the evolution and survival of life on Earth. A surface temperature of 59°F is sufficient to maintain the Earth’s reservoirs of life-sustaining liquid water, and to impel climatic

Also, what the effects from climate change on earth are, such as ozone depletion, ice cap density changes of water temperature, and how the animals in and out of the water are being affected. Let's start with the driving factors of greenhouse gases. These gases take in and put out gases that are in the inferred range. Most of the atmosphere on earth is made up of water vapor, methane, nitrous oxide, and carbon dioxide. Without a good level of these gases the earth’s temperature would be -15 degree Celsius or 0 degree Fahrenheit opposed to the average temperature of the earth 59 degree Fahrenheit.

Climate change is influenced by the greenhouse effect which is the increase of Carbon dioxide, Methane, Ozone and Nitrogen Oxide. On one hand, the presence of these gases in the atmosphere make the earth habitable with respect to regulating the earth’s temperature. However, an increase in the concentration of these gases results in trapping energy in the atmosphere and this in turn increases earth’s temperature. “Global greenhouse gas emissions have grown since pre-industrial times, with an increase of 70% between

Another thing we should consider is anthropogenic climate change that refers to the production of greenhouse gasses emitted by human activity. By examining the polar ice cores, scientists are convinced that human activity has increased the proportion of greenhouse gases in the atmosphere, which has risen over the past few hundred

When carbon dioxide and other toxic gasses are released into the atmosphere, they become too excessive for all the vegetation to absorb. Such conditions lead to the over-accumulation of gasses that form a layer called a greenhouse. The gasses create a greenhouse effect that prevents any heat from escaping the earth (Taylor,881). This means that most of the heat being released from the earth’s center as well as that being absorbed from the sun is retained within the atmosphere. The trapped heat has over time led to the rise in global temperatures which has subsequently had adverse effects on the ecosystem. In essence, the small changes to a temperature that have occurred on a global scale over time can lead to significant and human threatening changes in the global weather patterns. The contemporary warmth has been exhibited by melting ice lands and glaciers as well as increased floods and famines.

According to the National Aeronautics and Space Administration, the global temperature has risen about two degrees Fahrenheit since the late nineteenth century (“Climate”). Scientists define climate change as the escalation of the earth’s average temperature by natural causes or human inducement. As gases in the earth’s atmosphere increase, earth’s temperature follows coherently. Scientists cite a correlation between the earth’s increasing temperature and gases such as carbon dioxide, nitrous oxide, methane, and chlorofluorocarbons in the atmosphere. Scientists have found that through human activity these gases show an increase. The upsurge of gases has a lasting effect on the environment: “Scientists warn of the loss of ecosystems and

It is widely held that climate change is real and happening now Case (2006) as global average temperature has warmed about 0.8°C within the past century. Coupled with this, the past three decades has witness a global average warming of 0.6°C (Hansen et al., 2006). This is largely to due to human induced factors (IPCC, 2001). A recent report produced by the U.S. National Academy of Sciences confirms that the last few decades of the 20th century were in fact the warmest in the past 400 years (National Research Council, 2006). The IPCC also projects that if greenhouse gas emissions, the leading cause of climate change, continue to rise, the mean global temperatures will increase 1.4 – 5.8°C by the end of the 21st century (IPCC, 2001). In a similar

Climate is inherently variable. Climate changes from place to place and it varies with time. The world now faces one of the complex and important issue it has ever had to deal with: climate change. Climate change today is one of the biggest concerns of human beings on the planet and the effects of climate change are undeniable and it may cause environmental, social, and economic threats to the planet. We already know and easily can highlight several signs of climate change. They are: rising global sea level, widespread melting of snow and ice, rapidly changing ocean and global temperatures, and other signs. So, what are the causes of climate change? Is it natural or do human beings cause it? Well, in both cases we would be right. The climate change can be affected by natural factors, such as solar output, volcanic eruptions, and the Earth’s orbit around the Sun. Also, climate change can be affected by human activities such as, deforestation, burning fossil fuels, causing ozone hole, and building mass destructive weapons and using them on earth that causes a huge radioactivity on earth. Currently, the threat of global climate change does not threaten some nations to the extent of others. Compare the United States with the rest of African countries. We live in prosperity and in much easier time than the rest African countries. Most African countries cannot grow anything on their lands because of climate change. At the end, climate change might affect everyone on

In the world today their has been a surge of scientific, political and economical forces hurdling to prove and disprove the existence of global climate change. I assert that the "symptoms" that our planet is suffering are the truest indications to justify worrying about our collective future on this land; which I will present in terms of how the ecology is being effected by global climate change.

“The Greenhouse Effect” or “Greenhouse gases” have become somewhat of scary concepts in relation to climate change. In fact, without the Greenhouse effect, the average temperature of the Earth would be 5F rather than the current average at 59F. Greenhouse gases are composed mostly of water vapor, but also carbon dioxide, methane, and certain types of clouds. These gases lie in the troposphere of the atmosphere and allows the shortwave radiation of the sun to pass through the atmosphere and warm the Earth’s surface as energy is absorbed, while the longwave radiation is delayed from being transmitted back into space through greenhouse gases. The waves are absorbed by greenhouse gases and bounced back to the Earth’s surface, conserving

The earth’s climate is predicted to change because human activities are altering the chemical composition of the atmosphere through the buildup of greenhouse gases –– primarily carbon dioxide, methane, and nitrous oxide. The heat-trapping property of these gases is undisputed. Although uncertainty exists about exactly how earth’’s climate responds to these gases, global temperatures are rising. Go to the Emissions section for much more on greenhouse gases.

land and as it rises it hits the o-zone layer and bounces back into the earth

Climate change could be described as any process that causes adjustment to climate system be it a volcanic eruption to a change in the solar activity. Today, however, the phrase is most often used as climate change caused by humans. Climate change is also used commonly with another phrase – "global warming" – reflecting scientific observations of strong warming trends over the past century or so. Indicators like rising sea levels, retreating snow cover and glaciers, longer growing seasons and shifting wildlife has alarmed scientific community unanimously agreeing that the earth has warmed in the last century. Experts however are of the opinion that climate change is a more accurate phrase than global warming as the latter is just one component affecting the larger climate systems of the earth.

Some people say global warming is caused by human activity, others say global warming doesn’t even exist.
