Clearly, data and evidence are not popular among Pottertarians and other fantasists, but they will pick and choose the occasional isolated anomaly, but the scientific consensus is overwhelming. Consider, for instance, http://tinyurl.com/o3uryo5
A relevant quotation: "With records dating back to 1880, the combined average temperature over global land and ocean surfaces reached a record high for May, at 0.74°C (1.33°F) higher than the 20[sup]th[/sup] century average. This surpassed the previous record high anomaly of 0.72°C (1.30°F) set in 2010. Four of the five warmest Mays on record have occurred in the past five years: 2010 (second warmest), 2012 (third warmest), 2013 (fifth warmest), and 2014 (warmest); currently, 1998 has the fourth warmest May on record. Additionally, May 2014 marked the 39[sup]th[/sup] consecutive May and 351[sup]st[/sup] consecutive month (more than 29 years) with a global temperature above the 20[sup]th[/sup] century average. The last below-average global temperature for May occurred in 1976 and the last below-average temperature for any month occurred in February 1985."
Ah yes, NOAA.
Not all scientists are part of the "consensus" you refer to, Steven Goddard at Real Science is one of them:
“Bottom line is there is clearly a huge error in the USHCN adjustments which has added a non-existent one degree hockey stick warming to the official US temperature record, and I now know just where to look for it in their code,” Goddard wrote. “NOAA made a big deal about 2012 blowing away all temperature records, but the temperature they reported is the result of a huge error. This affects all NOAA and NASA U.S. temperature graphs, and is part of the cause of this famous shift.” Citing satellite data, Goddard also said that by 2008, U.S. temperatures had cooled down below 1980s and 90s levels.The “adjustment” schemes in the official U.S. dataset are so drastic, according to Goddard’s analysis, that they managed to “turn a 90 year cooling trend into a warming trend,” he said, suggesting that there may be a “software bug” at work. “Bottom line is that the [NOAA National Climatic Data Center] U.S. temperature record is completely broken, and meaningless,” Goddard concluded. “Adjustments that used to go flat after 1990 now go up exponentially. Adjustments which are documented as positive are implemented as negative.”
Respected climatologist and NASA scientist Dr. Roy Spencer actually showed evidence of what Goddard described as early as April of 2012, saying that “virtually all of the USHCN warming since 1973 appears to be the result of adjustments NOAA has made to the data.” Commenting on the latest findings, Dr. Spencer said that his own examination of the data and corrections to account for urban heat island (UHI) effects “support Steve’s contention that there’s something funny going on in the USHCN data.” He also called the NOAA methodology for adjusting the data “opaque” and said he believes it is prone to serious errors.
