This archive of climatic data houses both national and global datasets as part of the National Climatic Data Center's (NCDC) mission to describe the climate of the United States and to maintain records regarding trends and anomalies of weather and climate. Users may search the archive by data type, national or global coverage, and time period; or by resource type, such as satellite, radar, models, ... Full description.

This page describes El Nino and the Southern Oscillation and how they may contribute to severe weather and the destruction of sensitive ecosystems such as coral reefs. It features text, pictures, scientific illustrations, and links to satellite information and weather-related science activities. Full description.

Materials presented here are intended to help the learner understand the complex interactions between the oceans and the atmosphere that affect global weather and climate events. Users may learn how data from the TOPEX/Poseidon and Jason-1 satellites provide monitoring of oceanic conditions that may produce El-Nino/La Nina events, and help track the Pacific Decadal Oscillation (PDO), a long-term oceanic ... Full description.

Users can view a selection of animations of ocean surface temperature and dynamic height derived from data from the TAO/TRITON buoy array moored in the Pacific Ocean. The animations show temperature and surface topography variations consistent with the development of El Nino and La Nina events. Full description.

Users can select a variety of materials on El Nino/La Nina. Materials presented here include bibliographies, news articles, technical and research information, movies, animations, and cartoons. Full description.

This article describes the global weather factors used by Colorado State University Professor William Gray to make predictions on the number and severity of storms that will occur in a hurricane season. Links to forecasts and to other weather-related topics are included. Full description.

This news article examines evidence that parts of the Antarctic ice sheet have undergone episodes of instability that appear to correspond with periods of unusually warm temperatures in the Northern Hemisphere during the last ice age. Full description.

This press release examines recent evidence that the rate of global warming is accelerating, and that in the past twenty-five years it achieved the rate of two degrees Celsius per century, a rate that had been predicted for the twenty-first century. Full description.

This document provides an extensive description of a strategy to deliver credible predictions of future atmospheric carbon dioxide levels based on improved understanding of dynamics in the Earth's carbon reservoirs (the land, air and oceans). Full description.

Visitors to this site can read a discussion about the weather in Anarctica, including why it is so cold, how weather observations are conducted there, and what role the continent plays in the global weather system. Links to related topics, a wind chill calculator, and a Fahrenheit-Celsius-Kelvin temperature converter are also provided. Full description.
