The “Hottest” Temperature Game

Climate Deception: How The “Hottest” Temperature Game Is Played To Offset Prediction Failures

Guest essay by Dr. Tim Ball 

Global temperature is not doing what the “official” Intergovernmental Panel on Climate Change (IPCC) predicted. Proponents of the claim humans are the cause of warming and the cooperative media react by trying to deflect, divert and perpetuate fear. They exploit people’s lack of knowledge and understanding. A January 2013 ABC News headline said, “2012 Was 9th Warmest Year on Record, Says NASA” is a classic example of how the public are deliberately misled. It is deliberate because it distorts, is out of context, and exploits manipulation of statistics or as Disraeli summarized, “Lies, damn lies and statistics.”

The deception begins with the headline but is expanded in the article. The challenge is to know what is actually being said. Initially, you need a translator, but can develop sufficient propaganda detectors once the methods are identified. There are guidelines that work in most circumstances:

Don’t believe anything you read; Question everything; Be especially suspicious of numbers; Know the source and political bias; If you’re affected by the story get at least three other sources; Remember all government information and data is biased; Be especially wary of stories that cite authorities.

The opening paragraph to the ABC story says,

“The year 2012 was the ninth warmest globally since record keeping began in 1880, said climate scientists today from NASA. NOAA, crunching the numbers slightly differently, said 2012 was the tenth warmest year, and both agencies said a warming pattern has continued since the middle of the 20th century.”

The implied threat is the temperature continues its inexorable trend up. The record is 133 years long and with a general warming trend. When would you expect to find the warmest years? Figure 1 provides a hint.

Why are they drawing attention to this by focussing on the “ninth warmest”? Because for the last 15 years the trend has leveled and declined slightly in contradiction to their forecast. Figure 2 shows what is actually happening.

The IPCC claim with over 90 percent certainty that Figure 2 is not suppose to happen. Here is the actual data;

Figure 3

Notice how the shift caused a change in terminology to divert attention from the fact that CO2 was no longer causing increasing warming. CO2 levels continue to rise, but temperatures don’t follow. It completely contradicts their predictions, which is why they want to divert attention.

How meaningful is the temperature increase? What is the accuracy of the measure? IPCC says there was a “trend of 0.6 [0.4 to 0.8]°C (1901-2000)” , that is for most of the period in the news story. Notice the error range is ±0.2°C or ± 33%. It is a meaningless record.

The story cites NOAA and NASA in the standard appeal to authority. However, it’s offset by the observation that they are “crunching the numbers slightly differently” to explain why they disagree between 9th and 10th on the list. How can that be? Aren’t they using the same data? All agencies produce different average temperatures because they select different stations and “adjust” them differently. NASA GISS consistently produces the higher readings, and were most active politically when James Hansen was in charge. They both use the grossly inadequate surface station data.

Although the article limits its claim by acknowledging it is only the 9th warmest in the official record, most people believe it is the 9th warmest ever. It is a misconception deliberately created by political activists like Al Gore and not openly refuted by governments. It is like Gore’s claim that CO2 levels are the highest ever when they are actually the lowest in 300 million years.

So, how long and complete is the official record? A comprehensive study was produced by D’Aleo and Watts “Surface Temperature Records: Policy-Driven Deception?” detailing what was done. Two graphs from NASA GISS show the general pattern.

There are fewer than 1000 stations with records of 100 years and most of them are severely compromised by growth of urban areas. Equally important, is the decline in the number of stations they consider suitable, especially after 1990. This pattern also partly explains why the current readings are high (Figure 5). Temperature increases as the number of stations used are reduced.

Although they condition the terminology “hottest” with “on record” most people assume it is “ever”. This implication was deliberate. The IPCC rewrote history by eliminating the Medieval Warm Period (MWP) that was warmer than today. Weather agencies, increased the slope of temperature by lowering the old record – New Zealand is a good example (Figure 6).

Global temperatures are not following “official” predictions, so those who used global warming for a political agenda try to defend the indefensible. This proves it is political because scientific method requires you admit your science is wrong, determine why, and if possible make adjustments.
