Scientists in India make it clear that cosmic Rays are a far bigger influence on Earth’s Climate than Humans. Cosmic rays make clouds that reflect 90% of the Sun’s heating Radiation from their top surface. Since The Earth is shielded from Cosmic Rays by the Sun’s Solar wind, an active Sun means a warm Earth and an Inactive Sun means a Cold cloudy Earth. It is not the very small variation in Solar Irradiance that does it. It is the large variation in solar mass ejections as measured by Sunspots that does it. This fooled IPCC climate models into discounting the Sun’s effect in favor of Carbon Dioxide. Also, When the Water cycle is included in Earth Climate models, the vast heat transfers from water changing states to Vapor or Ice dominate. The Water cycle was also left out of IPCC climate models as being “Too Complicated”. This article and its references address the powerful effect of Cosmic Rays.
