1: This graph is highly topical. It is right up to date. Remote Sensing Systems, Inc. (RSS) is one of the two satellite-based datasets (the other is the University of Alabama at Huntsville (UAH). And RSS is one of the five standard global temperature datasets, which include the two satellite datasets and the three terrestrial datasets – Goddard Institute for Space Studies (GISS); the Hadley Centre/CRU dataset, version 4 (HadCRUT4); and the National Climatic Data Center (NCDC). As this month, RSS is usually the first to report, and its latest monthly value, for February 2014, became available just hours ago. As far as I know, no one else yet has a graph including this hot-off-the-press data point.

2: The satellite datasets are based on measurements made by the most accurate thermometers available – platinum resistance thermometers, which not only measure temperature at various altitudes above the Earth’s surface via microwave sounding units but also constantly calibrate themselves by measuring the known temperature of the cosmic background radiation, which is 1% of the freezing point of water, or just 2.73 degrees above absolute zero. It was by measuring minuscule variations of the cosmic background radiation that the NASA anisotropy probe enabled the age of the Universe to be determined: it is 13.82 billion years.

3: The graph is accurate. The data are lifted monthly directly from the RSS website. They are read down from the text file by a computer algorithm and plotted automatically using an advanced routine that automatically adjusts the aspect ratio of the data window at both axes so as to show the data at maximum size. The latest monthly data point is visually inspected to ensure that it has been correctly positioned. The light blue trend line plotted beneath the dark blue spline-curve showing the actual data is calculated by the method of least-squares linear regression, which determines the y-intercept and slope of the line via two well-established and functionally identical equations that are compared with one another to ensure no discrepancy between them. Least-squares linear regression is used by the IPCC and by most other agencies for determining global temperature trends. Interestingly, it is recommended by Professor Phil Jones of the University of East Anglia in one of the Climategate emails, so no one on the true-believing side will challenge its appropriateness. The reliability of the trend calculation by the algorithm was verified by Dr Stephen Farish, Professor of Epidemiological Statistics at the University of Melbourne.

4: The graph is visually very clear. The design, the layout, the colors used, the text font, and the line thicknesses are intended to be as clear and comprehensible as possible. The aspect ratio of the graph is similar to that of most modern television monitors, so that the graph can be displayed full-screen.

5: The graph is news. Not only is it very recent: it is also something that the mainstream news media very seldom reveal. They tend to keep the now embarrassingly long hiatus in global warming secret, so that this graph will astonish many viewers. I do not know of a more recent, more reliable, more accurate, more visually appealing graph.
