Discussions Discussion Climate Milestone
Monique Raynaud, May 14, 2013

An instrument near the summit of Mauna Loa in Hawaii has recorded a long-awaited climate milestone: the amount of carbon dioxide in the atmosphere there has exceeded 400 parts per million (ppm) for the first time in 55 years of measurement - and probably more than 3 millions years of Earth’s history.

Justyna C, May 11, 2013

Hi!
My name is Justyna. I am from Poland. My total footprint is 5359kg of CO₂ per year. My result is less than my class total footprint result( 7677 kg CO₂). My lowest category is “Transport”. I am surprised but I live very close to my school so I don’t need to go to the center too often. My highest category is “Home” probably because I and my family spend a lot of time in home . I very like playing on my computer and watching anime so I spend there too much time. My house is big and we heat months of the year. We use fluorescent bulbs in whole my house so it is not bad :P

    What is your primary mode of transportation that your total for that category is so low? Do you mostly travel by foot or by bike?

    My transportation total is also lower than my class - 1779 kg, with the average being 2443 kg - but I think that the only reason it is like that is because I hardly ever am in the car alone and I use my bike as often as I can for transportation (something very, very uncommon in my area of he US). And yet, it is probably considerably higher than your transportation average.

    My transportation was also lower than the majority of my classes score. I don't really go anywhere, but I do ride a bus to school. I love anime! I spend too much time on the computer too! :3

Ewa K-Poland, May 10, 2013

Hello, my name is Ewa. I’m 17 years old and I’m from south Poland. I have calculated my footprint and I found out that the total amount of CO2 I realise is 4757 kg per year. I’m glad because it is much lower than the average one realise in Poland - 6862kg CO2 per year and in the class is similar situation because class result is 7677.
The category which is my lowest one is a purchases -128. It doesn’t suprise me because I buy electrical equipmentl very seldom and when I really need it. The category which is my my highest one is home- 3139. It doesn’t suprise me too because me and my family spend a lot of time in the house. We use electronic equipment many hours a day, bulbs light up most of a day and we burn a lot of coal in the winter and sometimes in another seasons. I know it isn’t good.
I think my family can more ride on bicycle than by car, spend more relaxing time outside than e.g. on the Internet or Tv. We should burn less coal to heating my house but I do not think I persuaded my family to change the method of heating in a more ecological way because my parent thinks that it is more expensive to change it and maintain it.

    It's great that you think about protect our environment! Talk to your parents about your thoughts. Maybe they will change their mind;)

Discussions Discussion Is climate change real? Is it mostly human …
Mia S-USA, Nov. 25, 2012

It really bothers me when someone begins to talk about how global warming isn’t real or it isn’t our fault. Many times these people will use the defense that our winters the last couple years have been very cold. The second they say that I know they have no idea what they are talking about. Climate change does not happen over a couple years it happens over hundreds of years. The people that normally say that global warming is fake are normally the ones that have a large carbon footprint. They refuse to believe it is real because they are afraid of what could happen and they are afraid of change. I don’t think that we started global warming but we defiantly sped it up with our CO2 emissions. Now we need to keep it from speeding up even faster. We need to work individually on reducing our carbon footprints and not be afraid of change.

Discussions Discussion My Carbon Footprint
Juan Maquilon, Oct. 9, 2012

For transportation, my average was about 366 kg and the average in my region for transportation was 3447 kg. For home my average was 4000 kg and the average in my region for home usage is 5065 kg. For food my average is 4213 kg, the average in my region for food is 2996 kg. My average was 850 kg,the average in my region is 1606 kg.

Discussions Discussion Is Climate Change Mitigation 100% Beneficial?
Nathan L-US, Oct. 1, 2012

I feel as though there are several misconceptions as to what Climate Change does and how it directly effects us. What are your positions when it comes to the mitigation of Climate Change, and how would follow through with to have a significant international impact?

    You know, I think you have a point. Recently I’ve been doing research on global warming and found that it's not actually CO2 that's causing global warming, but methane released by, believe it or not, cow farts. As Noam Mohr, a physicist with degrees from Yale and Penn, says, the most prominent reason for global warming is really methane. An excerpt from one of articles says “By far the most important non-CO2 greenhouse gas is methane, and the number one source of methane worldwide is animal agriculture. Methane is responsible for nearly as much global warming as all other non-CO2 greenhouse gases put together. Methane is 21 times more powerful a greenhouse gas than CO2. While atmospheric concentrations of CO2 have risen by about 31% since pre-industrial times, methane concentrations have more than doubled. Whereas human sources of CO2 amount to just 3% of natural emissions, human sources produce one and a half times as much methane as all natural sources. In fact, the effect of our methane emissions may be compounded as methane-induced warming in turn stimulates microbial decay of organic matter in wetlands—the primary natural source of methane. “
    But I think it’s not just that the costs are too high, as your point shows, rather that it’s possibly too late to do anything at all. Prof. Veerabhadran Ramanathan, a Distinguished Professor of Atmospheric and Climate Science at the Scripps Institution of Oceanography and the University of California at San Diego, and Dr Nithya Ramanathan, a Fellow at the Centre of Embedded Networked Sensing at the University of California at Los Angeles and Presiden Nexleaf Analytics, along with the Carnegie Institution for Science Department of Global Ecology say that because CO2 actually stays in the air for very prolonged periods of time. I quote, “carbon dioxide emissions remain in the atmosphere for many centuries, because the ocean and vegetation on land absorb carbon dioxide only slowly over time. As a result, there is a warming effect long after the initial clearing of land… the relatively large amount of carbon dioxide that we are emitting today will continue to have relatively large impacts on the atmosphere and climate for many centuries into the future. “

    Also, Indean Salehyan, the Associate Professor of Political Science at the University of North Texas says that it’s really just bad allocation of resources and that it is often used as an end to some unjustifiable mean. Focusing on climate change in general as a violent threat acts as a diversion to catastrophe-relief and technology, according to a 2007 article. “These claims generally boil down to an argument about resource scarcity. Desertification, sea-level rise, more-frequent severe weather events, an increased geographical range of tropical disease, and shortages of freshwater will lead to violence over scarce necessities. Friction between haves and have-nots will increase, and governments will be hard-pressed to provide even the most basic services. In some scenarios, mass migration will ensue, whether due to desertification, natural disasters, and rising sea levels, or as a consequence of resource wars. Environmental refugees will in turn spark political violence in receiving areas, and countries in the global North will erect ever higher barriers to keep culturally unwelcome and hungry foreigners out. The number of failed states, meanwhile, will increase as governments collapse in the face of resource wars and weakened state capabilities, and transnational terrorists and criminal networks will move in. International wars over depleted water and energy supplies will also intensify. The basic need for survival will supplant nationalism, religion, or ideology as the fundamental root of conflict.¶ Dire scenarios like these may sound convincing, but they are misleading. Even worse, they are irresponsible, for they shift liability for wars and human rights abuses away from oppressive, corrupt governments. Additionally, focusing on climate change as a security threat that requires a military response diverts attention away from prudent adaptation mechanisms and new technologies that can prevent the worst catastrophes.”
    I have a a ton of evidence also that talks about how warming is actually good for biodiversity, but I want to hear what others have to say as well.
  • Jose Pelcastre Jose Pelcastre Oct. 2, 2012
    Owais Safaraz, I feel like the majority of the fight against mitigating climae change isn't done at home, because unless everyone switches to electrical cars, there isn't really a viable way for people to contribute to the fight against global warming. But that's okay, as Nathan Leal pointed to earlier, the government cannot possible, within our current limitations, “fix” climate change.
    However, my research, as mentioned earlier, could provide a solution that people at home could live by. As Mohr wrote, “The conclusion is simple: arguably the best way to reduce global warming in our lifetimes is to reduce or eliminate our consumption of animal products. Simply by going vegetarian (or, strictly speaking, vegan), we can eliminate one of the major sources of emissions of methane, the greenhouse gas responsible for almost half of the global warming impacting the planet today.” Of course, that means we have to do something with the cows, so it's almost called upon that we eliminate the cows in order to stop methane emissions at the source. That's not going to happen any time soon.

Hi!
when playing around with the calculator, i realized how high my carbon footprint is due to all the flights i make across the globe to visit my family in southern africa. i also realized how drastically the footprint decreased when changing meat quantites.
i would thus like to promote locally produced goods that can be transported within a country with environmental friendly veichles.

By promoting days like Meat Free mondays, which really isnt very hard because you do survive one meet free day per week, its not very much at all, and buying locally produced meat, we can make a huge difference on our co2 emissions!

ofcourse the problem remains that not everything can be produced everywhere at all times, but better start where we can instead of doing nothing! daily life changes is the most important factor in improving our results and reducing our co2 emissions. recycling papers and waste materials, turning off the tap when not using water while brushing our teeth, filling the dishwasher BEFORE turning it on will make a difference. dont wait for them big politicans and environment people to come up with a big fancy solution that will cause a paradyme shift in our society and ways of living, when doing things that should be obvious to us can make a huge difference immediately!

Be smart -Save the planet ^^

    i agree 112% with everything you said.
  • brandon bailey brandon bailey April 24, 2012
    i agree. everyone should be able to not eat meat aleast one day of the week .
  • abdelhamid derawi abdelhamid derawi May 5, 2012
    I strongly agree we should decrease the percentage of meat eaten daily. But then we should also decrease the amount of trees cut down every day.

Most people find it easy to talk about going green and reducing their footprint- but what does it really involve- here is a site with a few lists of ways to reduce in all the different aspects of your life. While we might not all have the time or the want to build a compost pile- there are surprisingly many simple ways to reduce our CO2 emissions that don’t involve altering our lives completely.

This is a advertisement campaign for reducing CO2. Very nicely put together. There are so many simple ways to cut down our emissions on a daily basis.
