  Perplexing Graphs

  I'm a skeptic looking to educate myself but everywhere I look for an argument for Global Warming/Greenhouse effect I see graphs that leave me less convinced than I was before.

  Why is your Holocene graph so horribly difficult to read ? I can't tell the difference between the lines representing the temp. over Antarctica and the amount of methane in the atmosphere. All I can tell is that the current temperature is a bit on the high side, but not as high as it has been previously and because all the lines are on top of each other, I can't see with any accuracy what temperature was at any of the other peaks on the graph.

  Your proxy data graph shows what appears to be a wide range of (unlabeled) yellow proxy data but why does all the non instrumental data show a perfectly linear decline in temperature ? Is it something to do with the "calibration period mean reconstruction" ? Again I can't tell which line is the dashed one and which one is solid black - I'm not even sure if the dashed line is straight or wiggly.

  You're not alone in this practice, watching 'An Inconvenient Truth' I found myself constantly frowning and trying to read the (often non existent)  axis labels and scales. I was never able to satisfy myself that the whole thing wasn't just a graphical variant of "lies, damned lies and statistics".On 'One hundred years is not enough'--Yes it is posted 3 years ago 18 Responses
