Introduction

Why is Global warming happening? Contents.... Introduction ... My case study is about global warming and why it happens. I am researching about global warming being caused naturally and manmade. Global warming is an issue because there is increase on co2 (carbon dioxide). The issues are that there are greenhouse effects; greenhouse gases and carbon footprint that can make the climate change for e.g. in Greenland the glaciers are melting because of the heat and make the deep water increase reaching Iceland coasts. Throughout my case study you will be reading about the greenhouse effect, global warming and the greenhouse gases and what it is. As well as this throughout my case study I will be telling you about the naturally made effects of global warming and also manmade effects of global warming. Greenhouse effects and Greenhouse gases Greenhouse effect is when the suns light heat called solar radiation. Solar radiation goes in the earth's atmosphere and some of it is absorbed on the earth's surface. Some of the solar radiation reflects from the atmosphere and the earth's surface. ...read more.

These gases join with water and produce acid rain. Acid rain is measured by PH scale and acid rain. Acid rain destroys many crop and livestock. "The effects, of course, were most severe in Iceland; ultimately, more than 75 percent of Iceland?s livestock and 25 percent of its human population died from famine or the toxic impact of the Laki eruption clouds." http://www.scientificamerican.com/article.cfm?id=how-do-volcanoes-affect-w (6/06/2011, 10:24pm). Volcano eruptions produce sulfur gases that are in the stratosphere. The sulfur gases once they combine with water they produce sulfuric acid the tiny droplet are light in colour. The sulfur acid falls on the earth and the stratosphere dries and sulfur droplets causes the earth to get cooled up. Evidence 2 Global warming is effected by Earth's soil produce carbon dioxide (co2).the soil releases carbon dioxide by respiration. The carbon dioxide comes from the ground into the atmosphere. "The researchers found that soil respiration had increased by about 0.1 percent per year between 1989 and 2008, the span when soil measurement techniques had become standardized." http://www.scientificamerican.com/article.cfm?id=soils-emit-carbon-dioxide The soil produce billions tons of carbon dioxide in the atmosphere every year. ...read more.

Conclusion

"Deforestation is responsible for about 20% of global carbon emissions, more than from all the cars, boats and planes in the world." http://www.time.com/time/magazine/article/0,9171,1642887,00.html Evidence 3 When burning fossil fuel carbon dioxide is produce and goes into the atmosphere. "an average of 496 billion metric tons" "http://www.scientificamerican.com/article.cfm?id=guaranteed-global-warming-with-existing-fossil-fuel-infrastructure" Conclusion My case study was about global warming. I wrote about natural and manmade effects of global warming. The natural effect of global warming is that volcanoes produce carbon dioxide "produce about 110 million tons of CO2 each year" and sulphur "sulfur gases that are in the stratosphere". I believe this is the case because the volcano releases a lot of gases in the air and there is after effects however deforestation could be the case because it causes the earth to heat up and on the image on page 8 it show the about of tons. I believe that the carbon cycle is the case because in the image it shows the different ways natural gases releases however carbon footprint is the case because human different actives releases gases and affects the carbon cycle. I believe that the Methane emissions is the case because methane comes from cows stomachs and from rice paddies however the pollutants page 9 are the case because the gases are stronger. ...read more.

  2. Is Global warming Natural or Man-made?

    Radiation from the earth's surface varies in wavelength with temperature. These are the greenhouse gases and, in order of importance, water vapor, carbon dioxide, methane and nitrous oxide. Each greenhouse gas gets absorbed at certain wavelength range. When the molecules absorb radiation it vibrates causing it to emit infrared radiation in all directions into the atmosphere and earth's surface.

    Let's start with something everyone need to do to survive, food shopping. More and more products now have a carbon footprint label as this article explains 3 "Carbon footprints Environment: Carbon-footprint labels, which indicate a product's environmental impact, are quietly spreading.

  2. Are humans to blame for Global warming or is it a natural phenomenon? ...

    Some potential effects of global warming Rising sea levels worldwide Due to an increase in global temperature, sea levels would rise worldwide. This would mean places such as Antarctica and Greenland would have their ice sheets melted. As ice melts it undergoes a physical change of state.

  1. Is human activity responsible for increased global warming?

    The fact that I have extrapolated my graph and predicted that the use of fossil fuels will increase, suggests that global warming may still increase in the future - this is manifest in showing that human activity is a prime factor of increasing global warming.

  2. What is Acid Rain? What are the effects of acid rain?

    The two main phases are the gas phase and the aqueous phase. As far as sulphur dioxide is concerned there is a range of possible reactions that may lead to the oxidation of the gas in the atmosphere each having a different degree of success.

    When this happens pressure builds up. When this pressure is eventually released, an earthquake tends to occur. The point inside the crust where the pressure is released is called the focus. The point on the Earth's surface above the focus is called the epicentre.

  2. Are Humans causing global warming?

    Now nearly everything you consume, nearly every product you buy, and many of your daily activities, involve the use of fossil fuels.? This shows that humans need fossil fuels in order to provide and create the valuable items that we need to live.
