This video describes the complex connections between land (the lithosphere) and other parts of Earth's climate system. Animations from NOAA show how distance from the equator affects average temperature in the Northern and Southern Hemispheres. The video emphasizes five land factors that influence climate: latitude, elevation, topography, surface reflectivity, and land use.

This is a multi-faceted activity that offers students a variety of opportunities to learn about permafrost through an important sink and source of greenhouse gas (methane), about which most students living in lower latitudes know little.

In this video, students see how data from the ice core record is used to help scientists predict the future of our climate. Video features ice cores extracted from the WAIS Divide, a research station on the West Antarctic Ice Sheet.

This climate change interactive modeling simulation simulates the interactions among different sets of variables related to climate change. This is a facilitated guided-inquiry exercise.

Arctic Report Card: 2011

The annual Report Card provides clear, concise scientific information on the state of the Arctic region, organized into 5 sections: Atmosphere, Sea Ice & Ocean, Marine Ecosystems, Terrestrial Ecosystems, and Hydrology & Terrestrial Cryosphere.  This edition was prepared by an international team of 121 scientists from 14 different countries.  Independent peer-review of the 2011 Report Card was organized by the Arctic Monitoring and Assessment Programme of the Arctic Council.

Atmospheric Aerosol Properties and Climate Impacts

A detailed look at global distributions and properties of airborne particles known as "aerosols." The report examines the various ways in which aerosols influence climate, and the uncertainties in our ability to observe and measure these particles' impact on the climate system.

Thresholds of Climate Change in Ecosystems

An assessment of the potential for abrupt state changes or regime shifts in ecosystems in response to climate change.  Better understanding of sudden changes to ecosystems, and the goods and services they provide, is extremely important if natural resource managers are to succeed in developing adaptation strategies.

Past Climate Variability and Change in the Arctic and at High Latitudes

Over the past 30 years, average temperatures in the Arctic have increased at almost twice the rate of the planet as a whole. Such temperature changes have been accompanied by shrinking sea ice, melting ice and permafrost on land, and widespread impacts to land and ocean ecosystems.

Abrupt Climate Change

An assessment of abrupt climate change events where key aspects of Earth's climate system change faster than the responsible forcings would suggest and/or faster than society can respond. This report examines four types of abrupt change in Earth's past that were so rapid and so large in their impact that if they were to recur today they would pose clear risks to society in terms of our ability to adapt.

Climate Projections Based on Emissions Scenarios for Long-Lived and Short-Lived Radiatively Active Gases and Aerosols

An assessment of the effects of short-lived gases and particles in the atmosphere. They can significantly change regional surface temperatures. By the year 2100 short-lived gases and particles may account for as much as 40 percent of the warming over the continental U.S. in summertime.
