Instrumental measurements, proxy data, climate model projections

In this activity, students explore past examples of climate variability in three locations: the Peruvian and Bolivian Andes, Central America, and coastal Greenland, and consider differences between climate variability and climate change.

This classroom resource is a combination of 3 visualizations and accompanying text that illustrate how 3 key natural phenomena - cyclical changes in solar energy output, major volcanic eruptions over the last century, and El Nino/Nina cycles - are insufficient to explain recent global warming.

NMME ENSO forecast

Because why go to the movies when you come to and watch the evolution of ENSO forecasts over the past two years?

The NOAA Sea Level Trends map illustrates U.S. regional and some international trends in sea level, with arrows representing the direction and magnitude of change. Students can investigate sea level changes around the U.S. and some worldwide using an interactive map interface with supporting data plots and tables.

This interactive tool allows viewers to explore, by county, the areas of California threatened by a rise in sea level through this century.

This is a series of 6 guided-inquiry activities that examine data and models that climate scientists use to attempt to answer the question of Earth's future climate.

This set of activities is about carbon sources, sinks, and fluxes among them - both with and without anthropogenic components.

In this video, Michael Mann and Stefan Rahmstorf explore some of the information from the 2013 IPCC 5th report in light of public perceptions of climate science.
