2014: Among the 3 percent Coldest Years in 10,000 Years

Guest Opinion: Dr. Tim Ball – Re-Blogged From http://www.WattsUpWithThat.com

We were told in October, before 2014 was over, that it was heading toward being the warmest year on record (Figure 1). The visual link of Polar Bears underscored the message. In fact, 2014 was among the coldest 3 percent of years of the last 10,000, but that doesn’t suit the political agenda.

We know the headline referred to NOAA’s projection, but the public only remember “warmest year”. It is a routine of manipulation of headlines practiced by bureaucrats and supporters of the Intergovernmental Panel on Climate Change (IPPC), from the start. The claim was not surprising, because NOAA was pushing 2014 as warm beginning in January with this headline NOAA: January 2014 fourth-warmest on record.” Various months were identified during the year, for example, “NOAA: August 2014 Was The Warmest On Record,” noting August was the warmest by a fraction. But they had already reported,

The summer of 2014 is officially the hottest since the modern instrumental record began more than 130 years ago, according to the latest state of the climate report from NOAA’s National Climatic Data Center.

By October they were summarizing the year.

“This makes the first ten months of 2014 the warmest January to October period on record and puts 2014 on track to be the warmest year recorded in the NOAA archive, which dates back to 1880.”

Bob Tisdale provided an excellent summary of the “Anticipation” for two surface records from GISS and NCDC. He was not surprised when these records appeared, showing 2014 was the warmest, according to them, by 0.02°C. Remember, this is from a record that is restricted by the historic record to measurements of 0.5°C. We also know the two satellite records, RSS and UAH, both show it was not the warmest year.

To counteract the headline you need something very dramatic, because there is nothing significant about the 2014 temperature as Tisdale plans to identify in an upcoming article titled, The Uptick in Global Surface Temperatures in 2014 Doesn’t Help the Growing Difference between Climate Models and Reality. He is interested in seeing how Gavin Schmidt, who replaced James Hansen at the Goddard Institute for Space Studies (GISS), is carrying the torch. History shows that GISS readings are consistently higher than all other sources. It is just one indicator of the temperature adjustments made so the AGW hypothesis fits the political agenda.

Challenges and IPCC Fixes

How valid is the 2014 claim? In the 10,000 – year context, it is significant because it is among the 3 percent coldest years, which is far more significant than the 100-year warm alarmists proclaim. There are two major reasons: Highest readings occur in the most recent years of a rising temperature record. Every alteration, adjustment amendment and abridgment of the record so far, was done to create and emphasize increasingly higher temperatures.

1. The instrumental data is spatially and temporally inadequate. Surface weather data is virtually non-existent and unevenly distributed for 85 percent of the world’s surface. There are virtually none for 70 percent of the oceans. On the land, there is virtually no data for the 19 percent mountains, 20 percent desert, 20 percent boreal forest, 20 percent grasslands, and 6 percent tropical rain forest. In order to “fill-in”, the Goddard Institute for Space Studies (GISS), made the ridiculous claim that a single station temperature was representative of a 1200 km radius region. Initial claims of AGW were based on land-based data. The data is completely inadequate as the basis for constructing the models.

2. Most surface stations are concentrated in eastern North America and Western Europe and became the early evidence for human induced global warming. IPCC advocates ignored, for a long time, the fact that these stations are most affected by the urban heat island effect (UHIE).

The UHIE was one of the first challenges to the claim of AGW evidenced in the instrumental record. Two graphs produced by Warwick Hughes were the most effective and appeared in 1991, shortly after the first IPCC Report in 1990. Figure 2 shows temperature at six major Australian cities.

A most likely explanation for the increasing UHIE, is expansion of the suburban area until it encompassed airport weather stations originally outside the city. The automobile made this possible. Figure 3 provides a comparison with 26 rural stations.

The difference is marked. What is equally interesting is that temperatures were higher in the first part of the record from 1880 and 1900.

3. There is a consistent revision of the record to lower historic readings. This increases the gradient of supposed warming. It is apparent in the New Zealand record(Figure 4).

A search of WUWT, using the term “Temperature adjustments”, yields a plethora of evidence. Every adjustment serves to change the gradient of the curve making today warmer than the past. Explanations, when given, usually provide little justification for the adjustment. The other tell tale sign is that virtually all adjustments occur before the UAH satellite temperature record began in 1991.

4. Policy anticipated that satellite data would replace the need for surface weather
