First, 20th century warming is unprecedented, and therefore should be attributed to human activity. Second, the 20th century warming cannot be explained by any other mechanism other than anthropogenic greenhouse gases (in particular, if the human radiative forcing is omitted, the global circulation models cannot explain the 20th century warming). The fraudulent "hockey stick" stood at the crux of the argument that 20th century global warming is unprecedented. It was used to eliminate the existence of the medieval warm period for example (this is not unlike George Orwell's 1984, in which people wake up one morning with a new history...). As the alarmists explain in their e-mails, the "hockey stick" is based on the manipulative "hockey stitch" where thermometer data was stitched after 1961 to disguise the fact that the reconstructed temperatures decrease). Thus, one cannot claim that the 20th century warming is unprecedented. Second, given the apparent measures alarmists take to stop the publication of any non-conforming voice, the apparent lack of any alternative explanation to 20th century global warming should only be viewed as the alarmists success to quench alternative views, not that alternative views do not exist. Indeed, there is an alternative explanation which explains a non-negligible part of the 20th century global warming, it is the sun.
