By\u00a0Kenneth Richard<\/a><\/em><\/p>\n\n\n\n

The globe may have only warmed by 0.41 to 0.83\u00b0C in the last 140 years.<\/strong><\/h4>\n\n\n\n

According to a new study<\/strong><\/a>, weather station data has been shown to non-climatically and erroneously record warmer-than-actual temperatures due to the steady and perpetual aging process almost universally observed in temperature gauges.<\/p>\n\n\n\n

When a weather station temperature gauge\u2019s white paint or white plastic ages and darkens, this allows more solar radiation to be absorbed by the gauge than when the gauge is bright white and new. Within a span of just 2 to 5 years, a gauge has been observed to record maximum temperatures 0.46\u00b0C to 0.49\u00b0C warmer than in gauges that have not undergone an aging process. This artificial warming is not corrected in modern data sets, and it builds up over time \u2013 even when the gauges are cleaned or resurfaced every few years.<\/p>\n\n\n\n

If these systematic artificial warming errors were to be corrected rather than ignored, the 140-year (1880-\u201990 to 2010-\u201920) GISTEMP global warming trend plummets from the current estimate of +1.43\u00b0C down to +0.83\u00b0C, a 42% differential. The temperature reduction can be even more<\/em> pronounced \u2013 from +1.43\u00b0C down to +0.41\u00b0C \u2013 if a set of conservative assumptions (described in detail in the paper) are removed.<\/p>\n\n\n\n

Interestingly, when the systematically erroneous temperature data are removed, or homogenized, at different intervals of time (2 years vs. 12 to 30 years, etc.), the global temperature trend \u2013 indeed, the long-term global warming<\/em> trend \u2013 can be shown to effectively disappear, depending on the time interval. This can be observed below, in Figure 7.<\/p>\n\n\n\n

As this chart illustrates, temperature data can homogenized, or adjusted, to exhibit just about any trend or non-trend the creator of the chart intends to. Data can be bent and manipulated to show strong warming, weak warming, or even no warming over the last 140 years.<\/p>\n\n\n\n

Perhaps the modern version of global warming is not nearly as unprecedented or even unusual as it is purported to be.<\/p>\n\n\n\n
