Sentences with phrase «average temperature changes remained»

Even the temperature reconstructions that show the greatest variations in the past 1000 years suggest up until the 1980s, average temperature changes remained within a narrow band spanning 1ºC at most.

Starting from an old equilbrium, a change in radiative forcing results in a radiative imbalance, which results in energy accumulation or depletion, which causes a temperature response that approahes equilibrium when the remaining imbalance approaches zero — thus the equilibrium climatic response, in the global - time average (for a time period long enough to characterize the climatic state, including externally imposed cycles (day, year) and internal variability), causes an opposite change in radiative fluxes (via Planck function)(plus convective fluxes, etc, where they occur) equal in magnitude to the sum of the (externally) imposed forcing plus any «forcings» caused by non-Planck feedbacks (in particular, climate - dependent changes in optical properties, + etc.).)

High - frequency associations (not shown here) remain strong throughout the whole record, but average density levels have continuously fallen while temperatures in recent decades have risen... As yet, the reason is not known, but analyses of time - dependent regional comparisons suggest that it is associated with a tendency towards loss of «spring» growth response (Briffa et al., 1 999b) and, at least for subarctic Siberia, it may be connected with changes in the timing of spring snowmelt (Vaganov et al., 1999).

«The Russian Academy of Sciences has found that the annual temperature of soils (with seasonable variations) has been remaining stable despite the increased average annual air temperature caused by climate change.

The percentage «remaining» in the atmosphere seems to correlate well with the annual change in global average temperature compared to the previous year, with years of relative warming showing higher % - age of the emitted CO2 «remaining» in the atmosphere.

In fact Australian and global average surface air temperature has remained more or less steady since 2001 (e.g. Nature Climate Change, volume 4, pages 222 - 227).

To return to an earlier point I raised that a linear lapse rate mathematically translates a temperature change at any altitude to other altitudes including the surface, I remain interested in observational data on linearity is terms of a flux - weighted global average.
