Lies, Damned Lies, and Global Warming Statistics [Video]

James Corbett – Don’t you hate when Fox News and the other MSM spin-meisters use simple tricks to skew and misrepresent data and statistics? How about when the World Meteorological Organization does it? Or NASA? Or the Journal of Climate? Or GISS? Join James for today’s thought for the day as he shows you some of the grade school level parlour tricks the global warming alarmists use to misrepresent their data and bamboozle the public.

Lying with Charts – Global Warming Graph

Global warming is a serious yet controversial enough topic without bringing in bad data visualizations practices into it. The Wonkblog on the Washington Post has an article titled, “You can’t deny global warming after seeing this graph“. The post reproduces a chart prepared by the World Meteorological Association that plots global temperatures by decade. While the data shows that the last decade, 2001-2010, was the hottest on record, the graph uses a broken Y-axis that begins at 13.4°C instead of starting at zero. The chart does not hide this fact, and you can see that the chart’s Y-axis starts at 13.4°C, but the most visually prominent piece in the graph is, well, the graph! And it screams the message that global temperatures are going off the charts – it’s time to panic. There is no denying that we as a world need to get serious about investing in alternative and renewable sources of energy like solar, wind, and even nuclear, but this graph is just plain bad.

The data: (from the web page):

1881-1890 13.68
1891-1900 13.67
1901-1910 13.59
1911-1920 13.64

How the data appears in a bar graph if plotted with the Y-axis starting at 13.4: Continue reading . . .
