Award-winning Israeli Astrophysicist Dr. Nir Shaviv: The CLOUD is clearing: cosmic ray flux ‘naturally explains the large solar/climate links’
Shaviv: 'As a consequence, anyone trying to understand past (and future) climate change must consider the whole effect that the sun has on climate, not just the relatively small variations in the total irradiance (which is the only solar influence most modelers consider). This in turn implies, that some of the 20th century warming should be attributed to the sun, and that the climate sensitivity is on the low side (around 1 deg increase per CO2 doubling)'
