The Southern Oscillation Index tracks differences in air pressure between the eastern and western sides of the tropical Pacific.

Temperatures measured on land and at sea for more than a century show that Earth's globally averaged surface temperature is experiencing a long-term warming trend.

Researchers Offer New Insights Into Predicting Future Droughts in California

According to a new NOAA-sponsored study, natural oceanic and atmospheric patterns are the primary drivers behind California's ongoing drought.

This OSU webinar will provide an overview of how interested stakeholders can obtain information from NOAA’s climate service offices.

USGS Coastal Change Hazards Portal

The U.S. Geological Survey's Coastal Change Hazards portal offers interactive access to coastal change science and data for our nation’s coasts. The portal is designed to aid decision-makers, organizations, or the general public make decisions that involve emergency preparedness, ecosystem restoration, and where and how to develop coastal areas. Anyone interested can explore the interactive portal to find information about historical or future potential storm impacts for a specific coastal area.

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 is a collection of five short videos - The Arctic Ice Cap, Sampling the Ice, Arctic Fisheries, Natives Feel Effect and Arctic Energy -- that can be played separately or in sequence. They show how climate change is affecting fishing, native populations and access for the oil and gas industry in the Arctic. The videos include personal reflections by writers Andrew C. Revkin and Simon Romero , scientists and residents about their experience of the impacts of the climate change in the Arctic.

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.

Considerations for Climate Change & Variability Adaptation on the Navajo Nation

A new report led by the University of Colorado Boulder summarizes the impact of climate change on Navajo Nation lands and discusses factors that affect people’s vulnerabilities to climate impacts, and outlines a way for the region's residents to plan for ongoing environmental change.
