Considering the actual spot covering fraction range that typical stellar variability
amplitude really translates to, a much broader range
of stellar contamination is possible than
previously considered.
If this state
of knowledge were to be revised in such a way as to indicate that the
amplitude of the climate variations were larger than
previously thought, that could very well call for for an upward revision
of climate sensitivity
As shown
previously in VTA - containing brain slices exposed to cocaine (Argilli et al., 2008), DA neurons showed significantly elevated potentiation
of mEPSC
amplitudes in PLE − / GFP + DA neurons in the presence
of CM - MK801, which further demonstrates the lack
of activity for CM - MK801 in PLE − neurons.

Of the spectral predictions, the one published (Clilverd et al., 2006) used a low - frequency modulation model that has some clear inadequacies, like including the Gleissberg 88 - year cycle that is no longer observable, assigning an extremely low
amplitude to the 208 - year de Vries cycle, and not including the modulation by the ~ 2400 - year Bray cycle that we have discussed
previously.
Superimposed on the secular trend is a natural multidecadal oscillation
of an average period
of 70 y with significant
amplitude of 0.3 — 0.4 °C peak to peak, which can explain many historical episodes
of warming and cooling and accounts for 40 %
of the observed warming since the mid-20th century and for 50 %
of the
previously attributed anthropogenic warming trend (55).
