«A careful survey of these stations by a team led by meteorologist Anthony Watts showed that 70 % of these stations have such poor siting that, by the U.S. government's own measure, they result in temperature uncertainties of between two and five degrees Celsius or more.» (judithcurry.com)
The new model found that temperature uncertainty associated with the social component was of a similar magnitude to that of the physical processes, which implies that a better understanding of the human social component is important but often overlooked. (nimbios.org)
Physically valid temperature uncertainties: none Physical meaning of the 0.2 C divisions: none. (planet3.org)
