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

This color-coded map displays a progression of changing five-year average global surface temperatures anomalies from 1880 through 2010. The final frame represents global temperature anomalies averaged from 2006 to 2010. The temperature anomalies are computed relative to the base period 1951-1980.

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 resource is designed as a module with a storybook or web story, and four activities. In the storybook, the GLOBE Kids investigate colors in the sky and learn how air pollution affects sky color and our health. Learning activities engage students in describing sky color and conditions in the atmosphere, creating a model to learn how sky color and visibility are affected by aerosols, using prisms to explore properties of light and colors, and collecting aerosol samples.

This monthly bulletin and animation provides regular and reliable visualizations of world weather and climate events of the previous month using NOAA data. Archives are available from October 2011 to present.

C-ROADS is a simplified version of a climate simulator. Its primary purpose is to help users understand the long-term climate effects (CO2 concentrations, global temperature, sea level rise) of various customized actions to reduce fossil fuel CO2 emissions, reduce deforestation, and grow more trees. Students can ask multiple, customized what-if questions and understand why the system reacts as it does.

This animated visualization represents a time history of atmospheric carbon dioxide in parts per million (ppm) from 1979 to 2016, and then back in time to 800,000 years before the present.

This series of four animations shows how some of the key indicators of climate change (average global temperature, sea level, sea ice extent, carbon emissions) have changed in Earth's recent history.

This video provides background information and teaching tips about the history and relevance of phenology and seasonal observations of plants and animals within the context of rural Wisconsin.

This is a full color, worldwide, animated weather map using GIS interface showing current and projected wind and other weather conditions for any location in the world. Data can be viewed at different spatial scales.
