Over the past 3 classes I have learned about my carbon footprint, what contributes to it, what more greenhouse gasses in the atmosphere mean, how to reduce carbon my carbon foot print and how ghg's trap heat. Using the carbon footprint calculator I was able to find out that most of my carbon footprint came from transportation, which I expected as I have to drive to and from sports, but compared to other Californians my carbon footprint not counting transportation was quite low, as I do not buy very much clothing and use it until it is too small/ beyond repair and will donate it if possible. According to the More Stuff=More Climate Change article, most of large and "first world" countries' carbon emissions come from transportation and purchases which explains why the transportation section of a Californian's carbon footprint was from transportation. I also learned how greenhouse gas compounds in our atmosphere use their polarity, which means that most of the positive-based atoms are on one side, and negative on the other to bounce back UV rays of heat back down to earth 1-2 times before it escapes into the atmosphere. This brings to mind the problem of having too many greenhouse gasses in our atmosphere, as it will trap the UV heat rays for longer thus increasing global warming. All of these things are connected as carbon footprints no matter how big or small contribute greatly to the amount of carbon(which is a ghg) in our atmosphere which bounce back more uv rays and thus raise temperature in our atmosphere, so in order to prevent the further rise in global warming we first have to lower our carbon emmsions by: Buying less things, using greener transportation, trying to invest in longer lasting and more sustainably crafted clothing and trying to eat foods grown locally while they are in season.
