The Influence of Cosmic Rays to Climate Change 2200897 Kang, sin-jae
Contents • Introduction • What is Cosmic Rays • Mechanism of Cosmic Ray’s Reaction • Relation between Cosmic Ray & Earth Climate • Summary
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.
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
Ice Epochs From Crowell(1999) From Scoteses’s “paleoatlas”
Ice Epochs &Galactic Rotation Ice Ages : Period=145.5 ± 7Myr Spiral Arms : Period=134 ± 25Myr
Cosmic Rays & Earth Temperature From Nir J. Shavi(2004)
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℃)
