Figure 2 is a screenshot of an online newspaper article. Figure 2a shows the article headline 'The Great Green Con no 1: The hard proof that finally shows global warming forecasts that are costing you billions were WRONG all along'. The article is by David Rose for the Mail on Sunday, published 23:37 16 March 2013. Figure 2b hows a graph of temperature anomaly forecasts on the y or vertical axis (from -0.5 to +0.5 °C) against year on the x or horizontal axis (from 1950 to 2030). The anomaly increases from about - 0.2 °C in 1950 to + 1.2 °C by 2030. The temperature forecast includes 75% and 95 % confidence ranges. A black line shows observations of temperature which are shown to lie largely within the 75% confidence range up to 2005, then starts to fall below it, appearing to fall outside and below the 95% confidence range by 2013.
