2015 was the year that proved to me that the data isn't accurate. We had one of the coldest springs I could remember. And I joked to my friends, no worries, it'll be claimed that it was the hottest on record. My friends laughed dismissively as we knew it was well below normal temperatures with the exception of a warm February.
Lo and behold, it was announced that 2015 was one of the hottest springs on record for the U.S. Now being the good student of the scientific method, I figured regional vs global here. Clearly, our region was well below normal temperatures. But I wagered the Southwest and pacific coast must have been warmer, and perhaps the south as well. But mid-atlantic to New England was clearly much colder than normal.
So I look at the data maps. And yes, there was a big hot blotch out westward. Just as I suspected. But then, they had my entire region in moderate red for elevated warmth. At this point, I am calling BS. Because we were well below normal temperatures for spring. In fact, I lost a crap ton of fruit crops due to extremely late and continual frosts.
So ya...I call BS on the data. It's not calibrated right.
