| The influence of cosmic rays on terrestrial clouds and global warming (3870 words) |
 | Also, because cloud formation processes probably differ in different meteorological regimes, such as pertain for instance over the tropics and the poles, and the cosmic ray flux is known to be dependent on magnetic latitude, we have examined the correlation between cloud factor and cosmic ray flux in different latitude zones, separately. |
 | Thus, the low cloud albedo change, and the increase in solar irradiance which accompanies increasing solar activity, both operate to warm the climate and the respective radiative forcing contributions are compounded. |
 | By analysing different low cloud types separately we found that clouds in a liquid phase account for almost all the variability during the observed period, leaving the ice clouds constant in time, except at the poles where a slight increasing trend for some of the ice cloud types is found. |
