Where is El Niño?  How is this year different from 2012 when El Niño was predicted, but never arrived?  

CFSv2 ensemble forecast Nino3.4 sea-surface temperature

The chance of an El Nino has dropped to about 65%. What led to this change in the forecast?

This interactive visualization is a suite of weather and climate datasets as well as tools with which to manipulate and display them visually.

This video is simple in its appearance, but it contains a wealth of relevant information about global climate models.

This visualization is a website with an interactive calculator that allows for estimation of greenhouse gas production from croplands in the United States.

In this activity students learn how Earth's energy balance is regulating climate. This activity is lesson 4 in the nine-lesson module Visualizing and Understanding the Science of Climate Change.

This video is the second of a three-video series in the Sea Change project, which follows the work of Dr. Maureen Raymo, paleogeologist at Columbia University's Lamont-Doherty Earth Observatory, who travels with fellow researchers to Australia in search of evidence of sea level that was once higher than it is today.

This video is the third in a three-part series by the Sea Change project, about scientists' search for Pleiocene beaches in Australia and elsewhere to establish sea level height during Earth's most recent previous warm period. This segment features the research of Jerry Mitrovica, Harvard geophysicist.
