The most credible global temperature data—properly comparable throughout the period investigated, and uncontaminated by local anomalies—are obtained by satellite measurement. That stretches back to 1979—which rather deflates “in recorded history.” The satellite data also deflate “hottest year.” 2014 was only the third warmest in the satellite record, behind 1998 (by 0.15C) and 2010 (by 0.13C). It only beat 2005 by 0.01˚C and the next six hottest years (2013, 2002, 2009, 2007, 2003, 2006) by at most 0.08˚C. Since the margin of error is about 0.1˚C, that makes those differences statistically meaningless. But the actual “recorded history” behind this headline is surface temperature measurements kept by NASA’s Goddard Institute for Space Studies (GISS) and the National Oceanic and Atmospheric Administration (NOAA). It goes back to 1880—conveniently excluding the three warm periods mentioned above. As David Whitehouse pointed out, even in these data, 2014 topped 2010 by only 0.01˚C, only a tenth of the margin of error and therefore meaningless. These data are also far less credible than the satellite data. Only a tenth of the margin of error and therefore MEANINGLESS!! In the meantime rising energy costs will hurt the poor around the world and our plant yield will decrease because they need CO2 to survive. We will all suffer from rising food costs because of this meaningless senseless nonsense!
