Global Warming Lab

Over the last several decades, climate change has evolved from a polarizing discussion to what will likely be the largest collaborative research project of our generation. While many aspects of climate change are still misunderstood, there is little debate that the concentration of carbon dioxide in the atmosphere is rising at an alarming rate. This rise is considered the main cause behind an increase in global temperature, which has set in motion a chain reaction of climatic events.

There are quite a few gases that are responsible for the warming of the earth’s climate. The list mostly includes gases like water vapor, carbon dioxide, methane, and ozone (Cause and Effect…). The way water vapor affects the climate is by keeping the air moist. When the air is moist it keeps the heat from escaping out to space, forcing the heat to stay in our atmosphere.

The greenhouse effect on earth results from a higher concentration of carbon dioxide, water vapor and methane in the atmosphere.

The greenhouse effect is when the heat from a planet's air warms the planet's surface to a temperature above what it normally would be without its air. What causes the greenhouse effect is that energy comes from the sun and reflects off of the earth’s surface and then goes back to the atmosphere as a bunch of heat. It affects the Earth by making the atmosphere warm.

Five gas molecules that attribute to the Greenhouse Effect are: Water Vapour (H2O), Nitrous Oxide (N2O), Methane (CH4), Carbon Dioxide (CO2) and Chlorofluorocarbons (CFCs). Carbon Dioxide is the most significant of these gases. This is because it is the most common of all the gases and acts as a very effective blanket to keep heat trapped in the Earth’s Atmosphere. Nitrous Oxide and Methane act in similar ways, but to a lesser extent since they aren’t produced as much. Water Vapour is also abundant like Carbon Dioxide, and it increases as the Earth’s temperature does due to the process of evaporation. This

Many chemical compounds present in Earth's atmosphere behave as 'greenhouse gases'. These are gases which allow direct sunlight (relative shortwave energy) to reach the Earth's surface unimpeded. As the shortwave energy (that in the visible and ultraviolet portion of the spectra) heats the surface, longer-wave (infrared) energy (heat) is reradiated to the atmosphere. Greenhouse gases absorb this energy, thereby allowing less heat to escape back to space, and 'trapping' it in the lower atmosphere. Many greenhouse gases occur naturally in the atmosphere, such as carbon dioxide, methane, water vapor, and nitrous oxide, while others are synthetic. Those that are man-made include the chlorofluorocarbons (CFCs), hydrofluorocarbons (HFCs) and Perfluorocarbons

Greenhouse gases, carbon dioxide and methane, absorb energy radiated by the Earth and then send it back into our atmosphere as heat. This is called the greenhouse effect. During the last

In this lab we explored the effect a given individual has on the issue of global warming. In part A, which determined the individual output of CO¬2 per year, we measured the mass of the CO¬2 that completely filled the plastic bag, as well as the elapsed time from start to end. From that data, we concluded that a single person can produce about 5.06 x 105 grams of CO2 per year. Although that may seem like an enormous amount, in perspective of the vast size of the Earth’s atmosphere, it barely constitutes 1 percent of the atmosphere. In the second part of the lab, we calculated the amount of CO¬2 that is produced by cars in a year. In my case, my Honda Odyssey travels about 13000 miles per year with a gas mileage of about 25 miles per gallon.

Carbon dioxide is a greenhouse gas. Greenhouse gas is the reflect radiation that the earth emits, and stop it from being lost into space. This causes the Earth 's temperature to be higher than it would be without greenhouse gases. Ever since the Industrial Revolution began around 1750, human activities have contributed a lot to climate change by adding carbon dioxide and among other heat-trapping gases into the atmosphere. Some scientists think that greenhouse gases are causing global warming, the rise of Earth 's surface temperature.

Greenhouse gases that are trapping heat is the leading role of global warming. When we extract and burn fossil fuels such as coal or petroleum, we cause the release of carbon dioxide into our atmosphere. This is a terrible effect because carbon dioxide can trap heat, and therefore makes it warmer. Though natural amounts of carbon dioxide have varied from 180 to 300 ppm, while today 's carbon dioxide levels are around 400 ppm. We also can tell that the additional carbon dioxide in the atmosphere comes mainly from coal and oil because the chemical composition of it contains a unique fingerprint. Greenhouse gases plays a major role in global

Most climate scientists agree the main cause of the current global warming trend is human expansion of the “greenhouse effect”: which is when the atmosphere traps heat radiating from earth towards space rather than allowing it to pass through. Certain gases in the atmosphere that do not respond physically or chemically to changes in temperature are described as “forcing” climate change. Water vapor is an example of this; it responds physically or chemically to changes in temperature and is seen as “feedback.”

Climate Change discusses the alteration in climate patterns over a period of time, from several years to millions of years. Climate change can happen in any direction and can be caused by many different factors such as variation in the earth’s orbit, volcanic eruption and so on. However, recently, due to unregulated human activities, many scientific researches showed that the temperature of Earth has constantly increased during the past half century. Therefore, climate change is now often referred to as “global warming”, which talks about the uncommon increasing in global climate temperature caused by human activities and the negative consequences it would bring to our environmental and ecological stability.

Ever since the Industrial Revolution humans have been releasing more and more carbon dioxide, which is accumulated in the atmosphere, this leads to the creation of the greenhouse, this disrupts our Earth’s climate. The greenhouse effect is when the energy from the sun drives the earth’s weather and climate and heats the earth’s surface, in turn the earth will radiate that energy back into earth which will cause a rise in temperature on earth because the gasses retain some of the outgoing energy trapping heat. Greenhouses gasses are carbon dioxide, methane, nitrox oxide water vapor and other gasses. These gasses originate from burning fossils which explain their capacity to produce energy. At first greenhouse effect was considered as a positive aspect but when greenhouse gases increase,

A greenhouse gas is described as any gas in the atmosphere that absorbs as well as emits radiation in the thermal infrared range. These are the primary cause of the greenhouse effect, which results in increased temperatures on Earth.

Green House Effect: When sunlight reaches Earth 's surface some is absorbed and warms the earth and most of the rest is radiated back to the atmosphere at a longer wavelength than the sun light. Some of these longer wavelengths are absorbed by greenhouse gases in the atmosphere before they are lost to space. The absorption of this long wave radiant energy warms the atmosphere. These greenhouse gases act like a mirror and reflect back to the Earth some of the heat energy which would otherwise be lost to space. The reflecting back of heat energy by the atmosphere is called the "greenhouse effect". The major natural greenhouse gases are water vapor, which causes about 36-70% of the greenhouse effect on Earth (not including clouds); carbon dioxide CO2, which causes 9-26%; methane, which causes 4-9%, and ozone, which causes 3-7%. It is not possible to state that a certain gas causes a certain percentage of the greenhouse effect, because the influences of the various gases are not additive. Other greenhouse gases include, but are not limited to, nitrous oxide, sulfur hexafluoride, hydrofluorocarbons, perfluorocarbons and chlorofluorocarbons. Almost 100% of the observed temperature increase over the last 50 years has been due to the increase in the atmosphere of greenhouse gas concentrations like water vapour, carbon dioxide (CO2), methane and ozone. Greenhouse gases are those gases that contribute to the greenhouse effect (Fig. 1). The largest contributing source of greenhouse gas
