This video describes how field research -- in this case, making water measurements in rugged mountain locations -- helps us to understand the complex relationships among changing climate, populations, and water usage.

This video is the second of three short videos showcasing the dramatic changes in Alaska's marine ecosystems. The video highlights the marine mammals and birds and how they depend on Arctic sea ice, as well as questions about how these animals will cope in the face of climate change.

This video from NASA features scientists who describe the role of salt in the oceans and global oceanic circulation, especially the effect of salinity on the density of water and its global circulation, with reference to global climate change.

This is a graph of marine air temperature anomalies over the past 150 years. Five different marine air temperature anomaly datasets from different sources are compared on the one graph.

This article and slide show from the New York Times, features several scientists from the University of Alaska, Fairbanks, who study the effects of thawing permafrost in Alaska.

This video addresses the impact of climate change on several butterfly populations. Warming temperatures lead to shifts in location of populations of butterflies or die-offs of populations unable to adapt to changing conditions or shift to new locations.

One of a suite of online climate interactive simulations, this Greenhouse Gas Simulator uses the bathtub model to demonstrate how atmospheric concentrations of CO2 will continue to rise unless they are lowered to match the amount of CO2 that can be removed through natural processes.

A colorful graphic that depicts the risks to the environment from different degrees of temperature rise. This graphic addresses how risks change as global mean temperature increases.

This is a figure from the 2007 IPCC Assessment Report 4 on atmospheric concentrations of carbon dioxide, methane and nitrous oxide over the last 10,000 years (large panels) and since 1750 (inset panels).

This video describes how the normal thousands-of-years-long balance of new ice creation and melting due to ocean currents has been disrupted recently by warmer ocean currents. As a result, glacier tongues that overhang the interface between ice and ocean are breaking off and falling into the ocean.
