OLR anomalies in 2012 versus 2014

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?

State of the Climate in 2013

On July 17, NOAA and the American Meteorological Society released the State of the Climate in 2013 report. A 24-year tradition encompassing the work of 425 authors from 57 countries, the report uses dozens of climate indicators to track patterns, changes, & trends of the global climate system.

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

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

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

This video features research conducted at University of Colorado's Institute of Arctic and Alpine Research, which studies isotopes of hydrogen trapped in ice cores to understand climate changes in the past.

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 provides an excellent summary of the role of the oceans and ocean life and makes the point that despite the important role of life in the oceans, there is still much to be learned about the details of the oceanic biota.

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.
