Data: (For definitions and equations see the methods section of Foster and Rahmstorf, 2011)
Data sources: GISTEMP, NOAA, HADCRUT, RSS, UAH, Berkeley. Karl(2015) and Karl(2015) global are the data from Karl et al (2015), with arctic infilling in the latter case.
Note: The 'End date' box is counterintuitive - it is given as a fractional year. So to calculate a trend ending at the end of 2012, you need to enter '2012.99', or if you prefer, '2013'.
