Experts say it’s too soon to call the recent string of very low ice years an emerging response to climate change, but the evidence in that direction is growing.

This lesson explores El Niño by looking at sea surface temperature, sea surface height, and wind vectors in order to seek out any correlations there may be among these three variables using the My NASA Data Live Access Server. The lesson guides the students through data representing the strong El Niño from 1997 to 1998. In this way, students will model the methods of researchers who bring their expertise to study integrated science questions.

This visualization is a website with an interactive calculator that allows for estimation of greenhouse gas production from croplands in the United States.

This activity comes at the beginning of a sequence of activities in an energy module. Students observe the transfer of solar energy to different appliances with a solar cell and then they investigate the effect of using different solar sources to supply energy to appliances.

This animated map shows prevailing surface wind direction and strength across the lower 48 states of the US.

In this activity, students explore energy production and consumption by contrasting regional energy production in five different US regions.

This video looks at the impact of changing climate on animal habitats around the world, showing how different creatures are responding to changing temperatures and precipitation patterns.

In this learning activity, students use a web-based carbon calculator to determine their carbon footprint on the basis of their personal and household habits and choices. Students identify which personal activities and household choices produce the most CO2 emissions, compare their carbon footprint to the U.S. and global averages, and identify lifestyle changes they can make to reduce their footprint.

In this learning activity, students use a web-based geologic timeline to examine temperature, CO2 concentration, and ice cover data to investigate how climate has changed during the last 715 million years.

In this activity, students use Google Earth to explore global temperature changes during a recent 50 - 58 year period. They also explore, analyze, and interpret climate patterns of 13 different cities, and analyze differences between weather and climate patterns.
