The greenhouse effect is named this as its the exchange of incoming as well as outgoing radiation that helps to warm the earth, this is similar to the same act and reason why we use greenhouses. A greenhouse is known for being successful in having the plants inside being able to be grown all year round, even if it\'s not the season for that plant, or it could be so cold outside, to cold for that plant to thrive. We know that a greenhouse is constructed of glass, having them made of sunlight allows sunlight to penetrate the exterior and warm all the air and plants that are inside.
Due to this the air inside generally naturally stays warmer than that of the outside air. All the heat that doesn’t get absorbed by the plants is still strapped inside by the glass which makes it unable to escape. In daylight hours, sunlight is able to keep coming through the glass, which adds more and more of that heat energy which helps the inside get warmer and warmer, which allows it to help stay warm even after the sun has set.
This is similar to how the greenhouse effect works. On a much larger scale to a greenhouse, the sunlight shines through the atmosphere that surrounds Earth and helps to warm up the surfaces on Earth. Like the greenhouse some of this sunlight is absorbed into the land, ocean and atmosphere but the rest of it gets reflected back towards space.
In the atmosphere there are many greenhouse gases that trap this radiating heat from Earth towards space.\nThere are greenhouse gases that surround our earth, some of the primary ones are carbon dioxide, methane and nitrous oxide. Those gases act as a blanket wrapped around our earth trapping all warmth inside. Greenhouse gases emerge naturally and assist to make up our surroundings. Those gases inside the greenhouse effect assist to preserve our earth at normal energy and warmth balance. The ‘blanket’ keeps the temperature of earth warmer than if the sun became the only source of warmth we got. Whilst sunlight reaches earth a number of it gets absorbed which warms the ground and some of it bounces back to space. The greenhouse gases in the atmosphere (water vapour carbon dioxide methane nitrous oxide ozone) can absorb and redirect some of the warmth back towards earth. The greenhouse effect is a essential component in preserving the earth, without it warmth might escape from the ecosystem out to space. Without the greenhouse impact the common of earth\'s temperature which is 14° c might come to be lots less warm and lifestyles wouldn\'t be possible. The temperature without these greenhouse gases and us just relying on the sun to warm us could be at -19° c so consequently we want the greenhouse impact for existence to hold on as regular and for destiny generations. The greenhouse impact is a natural manner that dates millions of years and has and could constantly play a essential position in regulating the overall temperature of our earth.
Humans have many impacts on our Earth and environment, they have also caused cycles like The Carbon Cycle to have a bigger impact on Climate Change and our Greenhouse Effect. The earth is made of spheres, the atmosphere, biosphere, hydrosphere and lithosphere. The atmosphere is the blanket which surrounds Earth, it\'s close to the surface of the planet due to gravitational attraction. The atmosphere contains all the air we breathe, helps to protect us from harmful radiation from the Sun, helps keep all the heat the sun provides from escaping into space, keeps the climate moderate, and contains all gases we use that help us live daily, without the atmosphere life on Earth wouldn’t be possible.
The biosphere is referred to as all living things/components on earth (humans,bacteria,animals,fungi,plants, all living things on land, in the air and in oceans). The biosphere dependents highly on the other spheres, atmosphere, lithosphere and hydrosphere. The hydrosphere refers to the water, it provides water or moisture to plants and animals. This is the layer of water that is near or at the Earth\'s surface, it can be found in liquid or frozen states. These include lakes, groundwater held in soil and rock, oceans, river, atmospheric water vapour (clouds, precipitation) dams etc.
The lithosphere is the outer part of the Earth which is solid, it also includes the upper brittle portion of mantle and crust, also referred to as the outermost layers of the structure of Earth. The Carbon cycle is the exchange of carbon between these spheres on Earth. Carbon Dioxide is present in the atmosphere as well as in ocean, air, and even rocks. Plants use carbon dioxide through a process called photosynthesis which along with sunlight helps them to grow and produce food/energy for themself. The carbon becomes embedded in the plant, and when that plant dies it goes into the ground to turn into a fossil fuel, like for example coal is a fossil fuel or oil over millions of years. Humans use fossil fuels though so they get dug up and used by humans which puts the carbon back into our atmosphere. As carbon dioxide is a greenhouse gas that helps us to trap heat into our atmosphere, it leads us back into the cycle of the greenhouse effect, where it redirects heat and helps to regulate our Earth.
This image demonstrates the carbon cycle and all impacts on the carbon cycle. The carbon cycle and greenhouse effect link together. In the carbon cycle carbon goes through the atmosphere as it is a greenhouse gas, and this carbon gets put into plants through photosynthesis. Many animals and people eat all these plants and meats that have carbon in them as well as the respiratory system involving carbon when you breathe out. When plants and animals decay, they go into the ground to either become fossil fuel or they can release their material back into nature to be reused by nature. This is where the greenhouse effect comes into effect as many people use fossil fuels and in fossil fuels carbon is stored as they are made of the remains of plants and animals which lived millions of years ago. Wood, coal, gas and petrol are all fossil fuels and are used in burning and combustion.
The carbon from the burning and combustion of fossil fuels puts out carbon and other gases that can be absorbed into the atmosphere or into the earth which help to regulate the earth\'s temperature and energy output as stated earlier.\nHumans have increased levels of Carbon in our atmosphere. When people consume electricity, they could be using different types of fossil fuels to power their electricity. They could use coal or petroleum, when people use coal it emits twice as much carbon into our atmosphere then what petroleum does. Another big contributor to the carbon that gets put into our atmosphere is transport. Transport is big anywhere you go, in the US locomotion is the second largest source of carbon emissions. International travel is big on our earth from planes to cruise ships. A study has shown that cruise ships at sea emit 12 times more carbon then when you are on vacation on land. Trees hold carbon in them, so when they get cut down or disintegrated all the carbon that was trapped inside gets released and increases the levels of carbon into the atmosphere. Even though deforestation isn\'t the biggest cause of carbon emission, all the forests and rainforests help to trap the carbon. Finally, industrial manufacturing emits a lot of the carbon dioxide in our atmosphere. The biggest transgressor is iron and steel manufacturing as well as cement production becing to the highest emitters.
The carbon cycle moves between the sphere, as the industrial revolution has had a major impact on the carbon emissions its starting to have an effect on the earth and atmosphere due to the fossil fuels it had created. \n https://climate.nasa.gov/evidence/ The graph in the source above, is based on the comparison of atmospheric samples that were frozen in ice cores and had tested more recently, this shows us the evidence behind the increase in carbon since the Industrial Revolution. So therefore this shows us how people have impacted the emissions they had been frozen into the ice from hundreds of years ago. In this graph it\'s good for showing the ups and down of the carbon dioxide levels parts per million, it\'s really detailed and shows all the rises in carbon and all the drops in carbon in our atmosphere. However, as it is over quite large period of time it\'s hard to pinpoint when exactly these rises and drops were if you weren\'t advanced and had full understanding in what it all meant and over how long .
This source above shows us the global carbon dioxide emissions on the left and on the right it shows the probabilistic temperature outcomes of different policies. We see on the left that this data is emissions from global energy and industry over the years and those predicted for over years to come. On the right we see the colours represent different temperatures and the likelihood of projected warming until 2100. In both the sources above they have clearly used colour to demonstrate the different types/ temperatures. However, they are predicting it for the future and we aren’t sure how accurate this can be, as well as not everything being labelled in a way easy to read for people who are just grasping an understanding on the topics.\n https://www.climatechangeinaustralia.gov.au/en/climate-campus/climate-system/greenhouse-gases/ This source is from 2014 and it shows the change in greenhouse gas concentration since 1975 in australia. Each line represents a different greenhouse gas and how it has increased over the years and at its rate. This graph is good as it clearly shows each of the different gases with its own colour and line which makes it easy to decipher which is which. However, this isn’t clearly labelled making it hard to see clearly what is being measured and in what amount.
Global warming is a growing issue on Earth. Global warming is when Earth’s temperature rises, this happens due to the buildup of the greenhouse gases in Earth’s atmosphere. These greenhouse gases are present so they can prevent infrared radiation from escaping into space, those gases also help to maintain Earth at a warm temperature. Levels of greenhouse gases can increase due to industry and from burning fossil fuels, is likely why there would be a rise in global temperatures. Overall, there is a total of 40 greenhouse gases in our atmosphere, however we know that carbon dioxide is the main contribute to the cause of global warming. Each year there has been a rise in temperatures, in the 20th century it was higher than ever before in the past 400-600 years.
