As I understand «climate» is a statistical evaluation of weather stats across time, usually across a ~ 30 year period for ease of comparison and having clear «standards.»

Albeit accurate, this recent 12 month data for each location should be considered statistically unreliable due to its brevity compared with «climate normals» that have typical year - to - year weather variations smoothed over standard periods (commonly 30 years).

So in Chapter 3, drawing on standard social science content analysis procedures and the measures used by Boykoff, I provide the first reliable and valid data evaluating systematic patterns in mainstream coverage of the reality and causes of climate change for the key political period of 2009 and 2010.

The likelihood of occurrence or the fractional area covered by 3 - standard - deviation hot anomalies, relative to a base period (1951 — 1980) that was still within the range of Holocene climate, has increased by more than a factor of ten.

Several people questioned the nature of «climate» and expressed the (common) confusion of «climate» with the «standard period of climate».

But 30 years was adopted as an arbitrary standard (i.e. the «classical period of climate») in the year of the International Geophysical Year (the IGY was in 1958 and it was thought that 30 years of climate data had then been amassed).

Heat pumps are going through a period of innovation including more wide - spread availability of ductless heat pumps, development of cold climate heat pumps, higher minimum efficiency standards for heat pumps, and development of gas - fired heat pumps.

These range from simple averaging of regional data and scaling of the resulting series so that its mean and standard deviation match those of the observed record over some period of overlap (Jones et al., 1998; Crowley and Lowery, 2000), to complex climate field reconstruction, where large - scale modes of spatial climate variability are linked to patterns of variability in the proxy network via a multivariate transfer function that explicitly provides estimates of the spatio - temporal changes in past temperatures, and from which large - scale average temperature changes are derived by averaging the climate estimates across the required region (Mann et al., 1998; Rutherford et al., 2003, 2005).

Thirty years is considered a standard baseline period for weather and climate, and the satellite record is now long enough to provide a thirty year baseline period.

[8] I estimate GISS - E2 - R's effective climate sensitivity applicable to the historical period as 1.9 °C and its ERF F2xCO2 as 4.5 Wm − 2, implying a climate feedback parameter of 2.37 Wm − 2 K − 1, based on a standard Gregory plot regression of (ΔF − ΔN) on ΔT for 35 years following an abrupt quadrupling of CO2 concentration.
