摘要: The well established excellent correlation between low-level clouds and primary cosmic ray intensity, which act as nuclei for cloud condensation, clearly shows that a decrease in intensity results lesser low cover. Reduced albedo radiation reflected back into space, due to cover, an increase the surface temperature on earth. Extrapolation of galactic using 10Be measurements deep polar ice proxy, has decreased by 9% during last 150 years, continuing solar activity. We present evidence show radiative forcing component years is 1.1 Wm−2, about 60% CO2 increase. conclude future prediction global warming presented IPCC4 requires relook take effect long-term changes intensity.
