A short video on the causes of ocean acidification and its effects on marine ecosystems.

This static graph of changes in CO2 concentrations goes back 400,000 years, showing the dramatic spike in recent years.

Video introduces wind energy research at the National Renewable Energy Lab (NREL) and provides an overview of the NREL Wind Technology Center near Boulder, Colorado.

This video is one of a series produced by the Switch Energy project. It reviews the pros and cons of natural gas as a source of energy.

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.

This video provides a good introduction to the field of attribution science. Beginning with an introduction to weather and climate, it describes how severe weather might be linked to climate change and the science behind attribution studies. It gives a good explanation behind how scientists use climate models to study whether severe weather events were influenced by climate change. It also discusses the question, "does climate change cause extreme weather?" and provides an introduction to the concepts of probability, causation, and correlation in regards to attribution science (how much climate change influenced an event verses normal variations in weather).

This is a multi-step, interactive tool for users to identify potential risks (to people, buildings, infrastructure, contamination, land) for selected coastal areas in the US, using scenarios of water level rising (as a result of tides, sea level rise, and storm surge) from 0-10 feet. Tool provides local, regional and national resources as guidance for managing risk.

This is an interactive website that provides descriptive information and data related to ten key climate indicators. These climate indicators and related resources show global patterns and data that are intuitive and compelling teaching tools.

These flow charts show carbon dioxide emissions for each state, the District of Columbia and the entire United States. Emissions are distinguished by energy source and end use.

This video from the U.S. National Academies summarizes the energy challenges the United States faces, including the technological challenges, and the need for changes in consumption and in energy policy.
