Greenhouse Effect
Since the beginning of the existence of planet Earth, different eras have shaped the atmosphere of our planet. But recently, the inhabitation of mankind has changed the levels of Carbon Dioxide in the atmosphere, on a rather unhealthy scale. Because of our emissions, we have given global warming no other path then to rise. The increased amounts of Carbon Dioxide and other gases put into the air are enhancing the greenhouse effect. The greenhouse effect, the trapping of the sun's warmth in the planet’s atmosphere, is causing global warming. In the greenhouse effect, shorter-wavelengths with higher energy are able to transmit through, but not out the atmosphere. On the other hand, long-wavelengths with low energy are able to be transmitted through the atmosphere and out freely. In our case, infrared radiation, which we feel as heat, becomes trapped inside the atmosphere. Our atmosphere heats up when it is exposed to the sun's heat, but eventually levels off at a certain equilibrium temperature, which is the average surface temperature. The equilibrium temperature is the point at which temperatures level out. Earth’s present day atmosphere includes Nitrogen (78%), Oxygen (21%), Argon (0.0093%), Carbon Dioxide (0.00035%), and Water (0.01%). In order to test out this concept of the greenhouse effect, we did an experiment in which we took two bottles, each filled up with dirt. The top parts of each bottle were cut off and we put a thermometer inside each bottle facing outwards. For the experimental bottle, we covered the top of it with plastic wrap and for the control, we left it alone. In the middle of the two bottles, we put a light bulb and at every five minutes, we checked the temperature of each bottle and record...

...that temperatures could increase by up to 6 degrees Celsius over the next 100 years. Well, scientist say the main cause of global warming is skyrocketing level of greenhouses gases, especially carbon dioxide and methane. And they agree that most of it is likely due to human activity. For one thing, the burning of fossil fuels puts more and more carbon dioxide in the air. Also, deforestation and has reduced the worldwide number of plants and trees, which take in carbon dioxide and produce oxygen. And then there’s our dependences on animals for meat and other products. The digestive system of cows and other livestock produce methane, which is more than 20 times as powerful a greenhouse as carbon dioxide! Unavoidable conclusion We need to work at reducing the amount of greenhouse gases that humans put into the mix. That is the best chance on keeping are earth on track.
Antarctic’s ice melt and accelerating sea level rise, the growing number of large wildfires, intense heat wave shocks, severe drought and blizzards, disrupted and decreased food supply, and extreme storm events are increasing to happen in many areas world wide and these are just some of the consequences of global warming. The fossil fuel we burn for energy coal, natural gas, and oil plus the loss of forests due to disforestation, in the southern hemisphere are all contributors for climate change. In the past three decades, every single year was warmer then the previous year and the warmest 12 years were recorded since 1998. We are overloading our atmosphere with carbon dioxide and trapping the heat and recently, the carbon dioxide level in the atmosphere reached 400 pmm. Not just environmental issues are rising due to carbon dioxide increase but more and miscellaneous issues are appearing as climate change becomes more severe. For example, regional models and local analyses agree that Mongolia has become noticeably warmer and the climate change effect is damaging their millennial of historic nomadic lifestyle and even came to the peek of extinction. The Mongolian nomadic pastoralists became highly vulnerable to many an unusual climate impacts and extreme temperature fluctuation that have led to inadequate pasture land and loss of enormous number of livestock, often faces hostile environmental conditions that led o entrenched pastoral poverty. This essay focuses on how the climate change impacts the qualitative and quantitative value of indigenous culture and nomadic life style, and how the economy struggles in the magnitudes of massive migration of nomads to urban area while it fails to value t...
According to Professor Mastrandrea the term global warming has been around for a long period of time. Back in the mid-1900s , humans were causing a lot of problems for climate change and none of that has changed since then , for example , starting fires or building gasoline engines. There are blueprints to global warming like, urgent deep reductions in carbon emissions, global reforestation efforts in semi-arid and drought affected regions and some of these have helped a diversity of nations but that doesn’t change the fact that global warming still occurs. All the unnecessary processes you can think of , have caused global warming , but people are still trying to prevent it (Mastrandrea).
... and feed grains (Nyong, 2008). Higher temperatures can the physiological development of crops such as causing increased respirations, shorter periods of seed formation and reduced biomass production which all result in hastened maturation and reduced crop yields (Adejuwon, 2004). Global warming and drought have affected the change in the incidence and distribution of pests and pathogens which presents challenges for crop management and animal rearing. Moisture and temperature are important elements of climate which determine the occurrence and localization of pests and diseases (Adejuwon, 2004). This is because pests and diseases vectors thrive well in optimum conditions of high temperature and abundant water supply. In this way climate change and global warming has extended the range of distribution of some pests and diseases worsening the plight of farmers.
For a significant number of years it has been evident that global temperatures were rising and that human activity is a major contributing factor to this rise. The rise in temperature is not only heating the planet but having an adverse effect on the global climate.
The effects of climate are felt throughout the world, all living things are affected with it. The effects of climate change are affecting directly the human life. It has been noticed that around the globe, seasons are shifting, temperatures are climbing and sea levels are rising. The world compares to century ago, it has changed drastically and it is becoming worse with climate change. Climate change will rapidly alter the lands and waters which we all depends upon for survival which will leave our children thus the future generation with a different world. In the time to come if not much is done for the case of climate change, There will be shortage of food and drinks, many new illnesses and diseases and some part of the world will become in appropriate for living things to live due to natural disaster. It can be that with the rapid Global warming and climate change, one-fourth of Earth’s species could be headed for extinction by the year 2050.
Climate change is a long term change in the earth’s climate. Climate change is attributed largely to the increased levels of atmospheric carbon dioxide produced by the use of fossil fuels. There are 328,000,000 cubic miles of seawater on the planet, covering approximately 71 percent of the earth's surface. Ninety-seven percent of all water is in the oceans. The other three percent is divided amongst the two percent ice and one percent fresh water. Making earth’s waters composed mostly of salt water. Salt water covers most of our planet indicating climate change to have a giant impact on our oceans. Taking a closer look at the ocean and our water in general can reveal several clues to the greater effects of climate change and what other ways climate change can affect our planet. (2)
Earth’s climate is determined by the physics and chemistry of its atmosphere. Earth’s atmosphere consists of four layers; troposphere which is closest to earth, stratosphere, mesosphere, and thermosphere. Hardy says, “During the past 100 years we humans, as a result of burning coal, oil, and gas and clearing forests, have greatly changed the chemical composition of the thin atmospheric layer.” There is more carbon dioxide in the atmosphere due to burning fossil fuels. The atmosphere is made up of many gases such as nitrogen, oxygen, and argon. It also consists of trace gases such as carbon dioxide, methane, carbon monoxide, nitrogen oxides, chlorofluorocarbons and, ozone. The trace gases have the greatest effect on our climate (Hardy 5). Up to a certain level, these gases help to keep the planet warm by absorbing certain infrared wavelengths, so that there can be life on the planet. Thus, they trap heat in the troposphere and stop it from escaping to space (Hardy 7). Therefore, the greater amount of greenhouse gases, the more heat trapped in the atmosphere. Earth’s temperature is increasing due to increased levels of greenhouse gases such as carbon dioxide released into the air from burning fossil fuels. The Intergovernmental Panel on Climate Change (IPCC) 2001 report projects “global average surface temperature increases ranging from 1.4 to 5.8 degrees
The truth is that the Earth is not experiencing rapid enough changes for all of that to be necessary (Salmon 25). Salmon also compared the global warming threat to a weekly weather prediction. He says that just like a weatherman is often wrong about the weather of the week, the predictions about Earth’s future weather are a little sketchy. If weather cannot always be predicted a few days in advance, then there is no way the claims of Earth’s weather over several years can be determined true (Salmon 24).
Air pollution and greenhouse gases are the reason for the planet as it is today; the reason why we see campaigns flooding the media informing us to ‘switch off’, ‘save the planet’ and ‘turn down the heat’ and the reason why the government is trying to develop a successful scheme, such as the carbon tax scheme, to reduce air pollution caused by major industries. Air pollution and greenhouse gases are the two immediate causes of global warming and climate change. Air pollution occurs when chemicals or particulate matter enter the atmosphere. They can cause damage to living organisms on the planet, as well as destruction to the natural and synthetic environment (Energy Environment.net 2008). Greenhouse gases are gases in the atmosphere that absorb infrared radiation emitted from the earth. They trap infrared radiation in the form of heat, and hence contribute to global warming. Anthropogenic greenhouse gases are a direct result of air pollution. They are the physical gases emitted that cause air pollution. Naturally occurring greenhouse gases also have an influence on the earth’s atmosphere, though it is not as conspicuous as anthropogenic causes. Together, air pollution and greenhouse gases are intensifying climate change and global warming on a world-wide basis.
Climate Change is any substantial change in climate that lasts for an extended period of time. One contributor to current climate change is global warming, which is an increase in Earth’s average temperature. Plants and animal species throughout the world are being affected by rising temperatures. Many plants are flowering earlier now than they once did; animals, such as the yellowbellied marmot, are emerging from hibernation earlier; and many bird and butterfly species are migrating north and breeding earlier in the spring than they did a few decades ago, all because of slight changes in temperature cues.

The warming of the Earth is known more commonly as global warming. Maybe this subject is going to be fought over for centuries while we squander the time we have left, but even if we did stop doing the things that cause global warming, it will not bring it to a standstill. The main cause is pollution, and although scientists say that crude oil will be a thing of the past, alternatives to it will be created. Whether you consider the future to be one hundred years away or just a second, the conception of the future is always the same. There are numerous views on the future, but each one says the identical thing.
all the time. The greenhouse effect is a natural process that keeps the earth at temperatures that
Our planet has managed to survive and thrive for about 4.54 billion years. In the last 2 million years we have caused enough damage and destruction to make our world “broken” beyond repair. We will not be able to get back the world we once had. The reason behind this is global warming, specifically, the increase of the global temperature due to the burning of fossil fuels and the release of greenhouse gas emissions into our atmosphere. If we do not make the issue of global warming a priority in today`s society, our entire way of life will be at risk. There are many reasons why so many people believe global warming should be a concern. Thoroughly examined points include: scientific predictions, rising temperatures, human causes, drastic climate changes and animal adaptations. Though there are several points arguing how global warming should not be a concern, the reality of the matter is that it needs to be taken into consideration on a global scale before it is too late, as to do nothing would have devastating implications on humankind.
According to the Canada’s Action on Climate Change, Climate change is a long-term shift in weather conditions identified by changes in temperature, precipitation, winds, and other indicators. Climate change can involve both changes in average conditions and changes in variability, including, for example, extreme events. Climate change is one of the biggest crisis in the earth. It will cause a huge damage to the eco-system and human. We are the victims of the climate change. However, we are the one who cause the climate change.
Global warming is an increase in the earth's temperature due to fossil fuels, industry, and agricultural processes caused by human, natural, and other gas emissions. This results in an increased evacuation of greenhouse gases. “Short-wave solar radiation sinks into the Earth's atmosphere and warms its surface while long-wave infrared radiation emitted by earth's surface is absorbed, and then re-emitted by trace gases.” (2)
