El Nino

The (limited and perhaps maladroit) changes I've made in the first bit of the article (ignoring, please, my snide comment), you may give a sense of where jargon might impede readability of the article.

However, could be a case in which "if you have to ask" then maybe you can't help, or maybe you can.

I've added article to "watch list" for the moment, and may try to marginally contribute. I don't pretend to understand subject with slightest depth, and would be cautious.

The larger problem is in its organization. 

A general reader wants to know, immediately, what are the potential consequences of El Nino. Instead, the article's lead grafs launch  into a long-winded and seemingly vague description of its history and theory that are more appropriate for deep into its body.
