One disadvantage of always working in standardized chronologies is that they lose sight of the fact that upper treeline trees have larger ring widths on average than lower treeline trees — which is not consistent with a linear gradient. (climateaudit.org)
The mean temperature of the troposphere is 256.5 K if we take into consideration the linear gradient across the troposphere from about +17 deg C at the surface to about -50 deg C at the end of the troposphere. (scienceofdoom.com)
