Two weeks ago, we published the first lesson in curve
manipulation taught by German school teacher and would-be
scientist E.G. Beck: How to make it appear as if the Medieval
times were warmer than today, even if all scientific studies
come to the opposite conclusion. Today we publish curve
manipulation, lesson 2: How to make it appear as if 20th Century
warming fits into a 1500-year cycle. This gem is again brought
to us by E.G. Beck. In a recent article (in German), he
published the following graph: Notice how temperature goes up
and down in beautifully regular cycles since 800 B.C.? At the
bottom, they are labelled “Dansgaard-Oeschger cycles” – this
refers to the Dansgaard-Oeschger events found in Greenland ice
cores during the last Ice Age (but not during the last 10,000
years), about which there is a serious scientific discussion
whether they are paced by a 1500-year cycle (see my paper in
GRL). Beck’s curve shows a warm phase 400 BC and the next one
1200 AD – that’s 1600 years difference, so it just abou
