 ay central roles in our understanding of physics. Topology explains the pr
 ecise quantization of the Hall effect and the protection of surface states
  in topological insulators against scattering from disorder or bumps. Howe
 ver discrete symmetries and topology have so far played little role in thi
 nking about the fluid dynamics of oceans and atmospheres. I show that\, as
  a consequence of the rotation of the Earth that breaks time reversal symm
 etry\, equatorially trapped Kelvin and Yanai waves emerge as topologically
  protected edge modes. Thus the oceans and atmosphere of Earth naturally s
 hare basic physics with topological insulators. As equatorially trapped Ke
 lvin waves in the Pacific ocean are an important component of El Nino Sout
 hern Oscillation\, these new results demonstrate that topology plays a sur
 prising role in Earth’s climate system.
