Can't find the Osborn&Briffa Science paper free online,but the following I
haven't seen mentioned here-

Harrison, R.G. and D.B. Stephenson, 2006: Empirical evidence for a nonlinear
effect of galactic cosmic rays on clouds , Proc Roy Soc A.,
doi:10.1098/rspa.2005.1628.
Abstract
Galactic cosmic ray (GCR) changes have been suggested to affect weather and
climate, and new evidence is presented here directly linking GCRs with
clouds. Clouds increase the diffuse solar radiation, measured continuously
at UK surface meteorological sites since 1947. The ratio of diffuse to total
solar radiation-the diffuse fraction (DF)-is used to infer cloud, and is
compared with the daily mean neutron count rate measured at Climax, Colorado
from 1951-2000, which provides a globally representative indicator of cosmic
rays. Across the UK, on days of high cosmic ray flux (above 3600X10^2
neutron counts hK1, which occur 87% of the time on average) compared with
low cosmic ray flux, (i) the chance of an overcast day increases by
(19+/-4)%, and (ii) the diffuse fraction increases by (2+/-0.3)%. During
sudden transient reductions in cosmic rays (e.g. Forbush events),
simultaneous decreases occur in the diffuse fraction. The diffuse radiation
changes are, therefore, unambiguously due to cosmic rays. Although the
statistically significant nonlinear cosmic ray effect is small, it will have
a considerably larger aggregate effect on longer timescale (e.g. centennial)
climate variations when day-to-day variability averages out.

Interesting stuff........

strange how sceince results like these NEVER make the mainstream press.

I remember that old hippie 'Cosmic Ray'. I can see him now in his Solar
Flares.
