Plenty of cosmic rays->Stimulate Ionization->Downward the cloud->Decrease the tempera-

ture

Short of cosmic rays->deteriorate Ionization->Upward the cloud->Increase the tempera-

ture

• Climate appears to be sensative to Cosmic Rays

• Cosmic Rays are responsible for large cli-mate

• Over 20th Century : Solar activity + Cosmic Rays = 2/3’s of warming
