Michael H. Glantz, Organizer

Summer 98 - A La Niña Summit -
Review of Causes and Consequences of Cold Events
15-17 July 1998

Workshop report about The Potential Use and Misuse of El Niño Information in North America.

The Colloquium consisted of presentations and roundtable discussions by scientists involved in ENSO-related research. It presented the current understanding of the causes, effects, and consequences of ENSO as well as ENSO's role in the global climate system.

This Web Site created a real-time interaction between the Internet community and the ENSO Colloquium by posting the abstract of each presentation and summaries of each day's discussions, and then posting emailed questions and Colloquium responses to these questions.
