Letter: Climate data from NOAA can't be trusted

A recent article noted that “in spite of no El Niño,” the Earth is still getting warmer. Furthermore, the article said 2017 was among the top two or three warmest years on record. So I guess the article intended to make us afraid that carbon dioxide from electric power plants and SUVs in the U.S. is going to kill us all.

Baloney, I say. 

For one thing, do not trust the data from the National Oceanic and Atmospheric Administration. This is a serious matter for us to be concerned about. Over the past decade, beginning about 2008, NOAA has been “adjusting” the climate data for the historical period from 1880 to date. The effects of these adjustments are summarized by as, “Before 1945 global temperatures are generally changed toward lower values, and toward higher values after 1945, resulting in a more pronounced 20th century warming (about 0.15 C) compared to the NCDC (National Climate Data Center) temperature record published in May 2008.” 

An interesting part of these adjustments is that the largest increase in temperatures was made by adjusting the data for 2016 way up. See Figure IV-5 in the analysis here. The “adjustments” taken overall make a significant increase in the apparent “tilt” of the climate data, making the historical data less cyclical (the cool period in the 1960s and 1970s is largely smoothed away) and more toward recent warming trends. 

Considering the politicization of the higher echelons of the FBI we have observed over the past few years, I suppose a politically correct NOAA would be no surprise. Disappointing, yes, but given the decades of misrepresentation of the data, not surprising.
