It seems that the global warming deniers may have made another major
error in their claims. They are looking at temperature anomalies,
which are basically variations from a trend, since the trend has been
rising over the last century or so, claims that the 30's were warmest
suffer from a simple mistake of confusing absolute temperatures and
anomalies.

Take a look at http://www.ncdc.noaa.gov/gcag/gcag.html

Notice how the figure on the right shows the trend and the 'anomalies'
it seems clear to me that while the 30's may have seen large
'anomalies', it can not be claimed that the 30's were anywhere the
warmest years...

The same from http://data.giss.nasa.gov/gistemp/

From absolute temperature data

Image right: The five warmest years since the late 1880s, according to
NASA scientists, are in descending order 2005, 1998, 2002, 2003 and
2006. Credit: NASA

Did McIntyre et al really make this big an error?
