Student Footprints

Students from around the world calculated their class mean and standard deviations for their footprints and posted them on our world map.

Do you see differences across the globe? If so, why do you think those differences exist?

Did you use the calculator to try to reduce your footprint down to the average from a citizen of another country? What changes would you have to make to lower your footprint in this way? Are you going to try and take some of these actions in your daily life?

Ways we can decrease the carbon dioxide in the atmosphere

   One major cause of global warming is humans and their needs. Humans produce over 35 billion tons of carbon dioxide a year. About 55% of the carbon dioxide goes to the water, and the rest goes to the earth’s atmosphere. Carbon dioxide is a greenhouse gas that keep the heat in our atmosphere. When the sun’s solar radiation reach earth, the solar radiation is absorbed by earth's atmosphere. This is caused because of greenhouse gases, like carbon dioxide. If there is an excessive amount of greenhouse gases in the atmosphere, the earth would start to heat up. This is horrible to our environment because if the earth gets heated up, then this will result in melting at the polar caps, ocean acidification, and many other hazardous things.
    Humans are the one major cause of global warming. Factories, cars, and airplanes are all used by humans. The following technology give out millions of carbon dioxide each month into the atmosphere because of brining fossil fuel. Even though I am a human and use the following technology, I believe we can become eco friendly.  Some ways humans can reduce the amount of carbon dioxide being released into the atmosphere is by installing solar panels. This could be a huge impact if almost all of the human population install solar panels in their homes. Another way people can reduce the amount of carbon dioxide is for most of the
population to drive hybrid cars, or cars that run on electricity. Both of these combined can reduce the amount of carbon dioxide released into the atmosphere.

I agree with you Amy, the human race is to blame for Global Warming because we are each releasing our carbon footprint and there are many consequences resulting in the carbon being released. One result of the CO2 levels rising is with Earth itself. Because we are all burning so much coal, oil and natural gas the carbon is not able to be released. This means that because of the factories, cars the fuel and gas and our actions from burning down forests carbon is being released into the air, because there is so much of it, it is not able to be released. Because the carbon cannot be released from our atmosphere the temperature is going up as well as the ocean's temperature. Carbon is the major trapping gas because we use it so often says Union of Concerned Scientists. Carbon has accumulated so much over the years that at this rate it would take us a century to get rid of the the carbon build up. Unfortunately even then there would still be about twenty percent of carbon in the atmosphere.
Other than the plant being at risk you and your loved was will be at risk as well. Bec ause of Global Warming there will be more wildfires, extreme weather events, health complications, heat waves, destructive hurricanes, more coastal flooding, longer seasons, melting ice and our military bases will be at risk. There will be wildfires because the temperature increase will make wildfire season longer and stronger as well as the seasons will be longer. Spring now comes ten days earlier and winter is now shorter. Also, there will be more coastal floodings because all the sea levels are getting higher which could put our military at risk. Another result in climate change that is already being noticeable is the health of our friends and family. Because of all the molecules in the air and more air pollution there will be a longer allergy season and more intense heat waves.
Plants can help stop climate a specific way. Plants are called “carbon sinks” says an article on Independent. Plants could stop global warming because they suck up all the carbon in the atmosphere to grow. The problem is because the temperature has risen tremendously and so many of the plants have died as a result of that. Because many of the plants have died they won't be able to trap the carbon in the atmosphere. Many forests can help with climate change, for example the Amazon Rainforest.
This is another example of climate change being the human race’s fault. I think that if we stop cutting down and burning all the forests then global warming could stop faster. This would help a lot because if we slow down climate change by not destroying our forests the plants will be able to suck up most of the carbon in the atmosphere. Another way we can prevent climate change from getting worse is by not releasing so much carbon into the air. One way we can do this is by not driving as much and walking to our desired destination. Also, we can cut the amount of electricity we use in our houses. One way we can do this is by turning off the lights when we are leaving a room.

Cristina and Amy, I believe there are many different ways to address this problem such as stopping deforestation. This can help the developing problem of climate change. The more living trees there are, the less change of climate there is because of a plant’s vital role in an ecosystem. Plants, thanks to their photosynthesis, can take in carbon dioxide, a greenhouse gas, and turn it into oxygen. Hence, the more forest, jungles, and greenery in general, the less carbon dioxide in the Earth’s atmosphere. Plants can also help cool the Earth directly through the process known as transpiration. When the surrounding area heats up, plants will often release excess water into the air from their leaves. By releasing evaporated water, plants cool themselves and the surrounding environment. “It’s like sweating. When you sweat you cool the surface of your skin,” says Wolfgang Buermann of Boston University. Over a forest canopy or a vast expanse of grassland, large amounts of  transpiration can increase water vapor in the atmosphere, causing more precipitation and cloud cover in an area. The additional cloud cover often reinforces the cooling by blocking sunlight.
