Holy 3 annotated sources on climate change Batman!!

Source 1:GWsource_1
Historical CO2 Record from the Vostok Ice Core 

  • Shows co2 data from the past 400000 years
  • Shows an upward trend in recent years
  • one of the main components in the graphs used by al gore
  • this data comes from antarctic ice cores going down 3304m
  • takes into account age of ice and air from samples

Source 2:GWsource_2
Historical Isotopic Temperature Record from the Vostok Ice Core  

  • uses the Vostok ice data to calculate temperature data
  • temp data goes back over 400000 years
  • has no temperature variation in the last 120 years
  • a brief look over seems to show a large amount of negative numbers
  • this data is used as the standard for graphics on climate change

Source 3:GWsource_3
Estimating the uncertainty of the Mann et al. (1998, 1999) reconstructions 

  • bring into question the accuracy of the Mann et al study
  • Defines the complicated terms that relate to error in a way that most people can understand
  • shows a similar but different trend than the one seen in AIT 
  • Admits to possible error in his data and asks for reviews to clarify
  • brings into question weather the smoothing models used on the graphs change the outcome
  • bring up possible errors and solutions with graphs and data readings.


I believe that by using the same sources that were used by the scientists, i will be able to create a balanced  set of data that are not influenced by media. In my senior project I will be able to use this data to make predictions about the future and the effect that climate change will have on human life.

I also included a media article because it shows a good way for me to find my own data. I admire the way the the author of the JunkScience website used data to come to his own conclusion without the influence of data or "facts" that mainstream media gives. This makes his finding a little more reputable.

    1. I understand what your going with, but i don't understand what you are actually focusing on,"deforestation, biodiversity etc" I think you need to make it more clear what you are focusing on, and elaborate.

    2. Paul!
      You have really good resources and I can tell that you have put a lot of thought and time into this blog. My only concern is that you could get more in depth on how you plan on using all this information into your senior project. Like what film ideas do you have? I know you have a lot.
      (:

    3. These are very reputable sources that will be a strong point of your argument but I am not sure exactly what topic you are choosing to pursue. What argument will this data support?
