Recent calculation errors

There have been a few reports in the press recently where calculation errors have led to spectacular claims. They include:

The Intergovernmental Panel on Climate Change (IPCC) have admitted that the figure of 55% of the Netherlands lying below sea level quoted in a 2007 report was incorrect. In fact the correct figure is 26%. The report used data for areas of the country prone to flooding, which includes land alongside rivers that is above sea level. Reported in the Guardian by Robin McKie on 14 February 2010

In the same IPPC report it was claimed that Himalayan glaciers could melt away by 2035. Apparently this was based on "poorly substantiated estimates of rate of recession" and was unfounded. Reported in the Guardian by RDamian Carrington on 20 January 2010

The UK Conservative Party claimed in a dossier that 54% of girls in the 10 most disadvantaged areas of UK get pregnant before they turn 18. The figure was actually 5.4%. Reported on the BBC website 15 February 2010

Many people have been issued the wrong tax code, which may result in them paying extra tax.
