temperature T obtained at the global network of
meteorological stations (ftp//ftp.ncdc.

Blue horizontal line is the averaged temperature
for 1880 -2005. Vertical blue bars are standard
errors.

  • 7. Is prognosis on the cooling climate justified
    or not?
  • In Fig. 5 the change of ?T over the globe are
    shown for the period of 1985 present time. It
    is seen that in the beginning of the 21st century
    the warming process was stopped and during the
    recent years the climate cooling is observed.

Fig. 2. Altitudinal profiles of CR fluxes
obtained at different latitudes from the
equatorial (Rc 14 GV, bottom curves) to polar
ones (Rc 0.03 GV, upper curves). The
measurements were performed in solar activity
minimum of 1987.

Fig. 3. Time dependence of the global CR flux in
the northern polar atmosphere (Rc 0.6 ?? ) at
the altitudes from 25 km (upper red curve) till
12 km (lower orange curve).

Fig. 7a, b. On the left panel (a) altitudinal
profiles of CR fluxes J(h) and on the right
panel (b) ion production rate q(h). The values
of J(h) and q(h) were measured and calculated at
the latitudes with different values of Rc (shown
near each curve) and correspond to the period of
high solar activity level.

(b) Altitudinal profiles of CR fluxes. These
data were obtained during solar activity maximum
at the latitudes with different values of Rc
(figures near curves).
