  1. The Influence of Cosmic Rays to Climate Change 2200897 Kang, sin-jae

  2. Contents • Introduction • What is Cosmic Rays • Mechanism of Cosmic Ray’s Reaction • Relation between Cosmic Ray & Earth Climate • Summary

  3. Introduction • What is the major Source for Global Warming? • Just Caused by human? • Co2? Water Vapor? • How about Cosmic Rays? • Here’s the New Theory.

  4. What is Cosmic Rays?

  5. Mechanism of Cosmic Ray’s Reaction • Plenty of cosmic rays ->Stimulate Ionization ->Downward the cloud ->Decrease the temperature • Short of cosmic rays ->deteriorate Ionization ->Upward the cloud ->Increase the temperature

  6. Cosmic Ray Flow

  7. Ice Epochs From Crowell(1999) From Scoteses’s “paleoatlas”

  8. Ice Epochs &Galactic Rotation Ice Ages : Period=145.5 ± 7Myr Spiral Arms : Period=134 ± 25Myr

  9. Cosmic Rays & Earth Temperature From Nir J. Shavi(2004)

  10. Sun Spot’s Activity

  11. Distribution of Earth’s mean temperature

  12. Influence factor For Temterature Change

  13. Summary • Climate appears to be sensative to Cosmic Rays • Cosmic Rays are responsible for large climate • Over 20th Century : Solar activity + Cosmic Rays = 2/3’s of warming (0.37±0.13℃ out of 0.57±0.17℃)
