The globe may have only warmed by 0.41 to 0.83°C in the last 140 years.
According to a new study, 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.
When a weather station temperature gauge’s 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°C to 0.49°C 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 – even when the gauges are cleaned or resurfaced every few years.
If these systematic artificial warming errors were to be corrected rather than ignored, the 140-year (1880-’90 to 2010-’20) GISTEMP global warming trend plummets from the current estimate of +1.43°C down to +0.83°C, a 42% differential. The temperature reduction can be even more pronounced – from +1.43°C down to +0.41°C – if a set of conservative assumptions (described in detail in the paper) are removed.

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 – indeed, the long-term global warming trend – can be shown to effectively disappear, depending on the time interval. This can be observed below, in Figure 7.
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.
Perhaps the modern version of global warming is not nearly as unprecedented or even unusual as it is purported to be.
THe GHE is overstated 100 to 1 because the theory says GHGs emit all the radiation they absorb, but reality is they conduct 99% of the energy they absorb to bring all the 99% non-GHGs at each altitude into local thermal equilibrium (the same temperature). Since the GHE is overstate 100 to 1, therefore AGW which is based on the GHE is overstated 100 to 1.

Talking about political science! Better politicized climate science.
What a sorry state of affairs…..
