Is there a tie between El Nino and global warming?
This is a matter of considerable speculation in the climate research community. It is plausible that a warmer earth would produce more and stronger El Ninos. There is some evidence that the earth has warmed over the past two decades, and there is no doubt that El Nino has been much more frequent in that time. If the evidence of a warming earth is taken at face value (not universally accepted), there still remains a wide spectrum of opinions on whether we are seeing a manifestation of human modification of global climate, or whether the natural climate system would be exhibiting this behavior anyway.
