    Utterly irrelevant
    Probably has something to do with prohibition.

    <b>Hockey Stick Manipulated Data</b>

    Both the Greenland GISP2 temperature curve (Figure 1B) and the oxygen isotope curve (Figure 1C) clearly show that except for the Little Ice Age and Dark Ages Cool Period, temperatures for all of the past 4,000 years have been warmer than the end of the ice core (1950 AD). The Medieval Warm Period was 1.1° C warmer than the top of the core (1950) and at least four other warm periods of equal magnitude occurred in the past 4,000 years; four other warm periods were ~1.3°C warmer; two other warm period were 1.8-2.0°C warmer; and one warm period was 2.8°C warmer. At least a dozen periods more than 1°C warmer than 1950 occurred, clearly contradicting the Marcott et al. conclusions.

    The top of the GISP2 ice core is 1950 AD, so we need to look at more recent temperatures in Greenland in order to get to the “present temperature,” i.e., has the temperature in Greenland risen since 1950? Figure 2 shows 1880 to 2004 temperatures in Greenland (Chylek et al., 2004, 2006). Temperatures in 2004 were slightly lower than in 1950, so temperatures at the top of the Greenland ice core are not significantly different than those “at present.”

    Next, Watts addresses Marcott’s assertion that “Global temperature…has risen from near the coldest to the warmest levels of the Holocene within the past century. A heat spike like this has never happened before, at least not in the last 11,300 years.”

    Let us test this conclusion against real-time data. First, their statement that “Global temperature…has risen from near the coldest to the warmest levels of the Holocene within the past century” is not true. The coldest part of the Little Ice Age occurred about 400 years ago, during the Maunder Minimum, so right off the bat, their conclusion is flawed. They appear to be unaware of the cyclic nature of temperature change and use the low point of the 1880-1915 cool period as their starting point for assessing the rate of warming over the “past century,” rather than 1913-2013. Comparing the depth of cooling in a cool period with a warm period peak is comparing apples and oranges. It distorts the real rate, which should be measured from cool peak to cool peak or warm peak to warm peak. The 1880-1915 cool period was followed by the 1915-1945 warm period, the 1945-1977 cool period, and the 1978-1998 warm period (Figure 4). The rate of warming from 1913 to 2013 is about 0.7°C per century (which is about the same as the warming rate over the past 400 years as we have been thawing out of the Little Ice, long before atmospheric CO2 began to rise significantly).

    11 year average for a 35 year period of data.. the sample is way to small to arbitrarily pick a moving average about a 3rd the length of the entire data set.

    that should smell like bullshit to anyone on a trading board.
    ====
    its obviously rigged to avoid showing that our temperature has been going down for the last 7 to 10 years... and that over the last 17 temps have not been going up.

    Real Temperature... not an obviously rigged average look very much like that solar chart lately.
