Instrumental measurements, proxy data, climate model projections

Computer climate models help scientists such as Dave Dewitt predict the life cycles of individual El Niño or La Niña events and their effects on weather patterns throughout the world. While the accuracy of these models continues to improve, they still have limitations.
 

Will climate change affect frequency or intensity of El Niño and La Niña? There is still little consensus among scientists on this, explains the International Research Institute for Climate and Society’s Lisa Goddard.
 

This report presents a comprehensive appraisal of Earth’s climate in 2009, and establishes the last decade as the warmest on record. Reduced extent of Arctic sea ice, glacier volume, and snow cover reflect the effects of rising global temperature.
 

Deke Arndt, chief of the Monitoring Branch at the National Centers for Environmental Information, kicks off a new blog that will cover how climate records are collected and updated, how we know what we know about the climate, and how we can use climate information to make our communities more resilient.

ENSO is a complicated thing to model. What are the challenges, and how can we overcome them?

NOAA Climate Stewards September Webinar
April 13, 2015

NOAA’s Climate Stewards Education Project is honored collaborate with Cultural Specialists from the Smithsonian Museum of the American Indian, Project Indigenous, and Educators from the University of Wisconsin-Extension to present this webinar on TEK, how it can inform our understanding of a changing climate's impacts on coastal and inland Indigenous people, and useful teaching materials to bring these ideas together.

The model predictions during 2014 were not that shabby.  A major, strong El Niño was not well justified by the predictions.
