The video addresses impact of warming temperatures on major lakes of the world with specific focus on Lake Superior and Lake Tanganyika. It discusses the science of water stratification and its impact on lake ecosystems and on human populations whose livelihoods depend on the lakes.

This beautifully filmed and produced video describes the changes that global warming is already bringing to Northern Canada and Greenland. Local people describe changes to ecosystems, impacts on culture and life styles, and the challenges of melting permafrost. Ship captains describe changes in navigational channels and fjords. Scientists describe changes in albedo and permafrost, as well as increased pollution transported from outside the Arctic (the Grasshopper effect).

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.

This video discusses impacts that the Eastern US is experiencing due to climate change. It describes the seasonal shifts that may affect tourism in New England, extreme heat in the Southeast, how rising sea level affects coastal areas, changes in hurricane intensity, the spread of invasive species and disease, as well as other topics.

In this learning activity, students analyze an actual dataset of the influence of temperature on tree growth. They use mathematical and statistical concepts like slope equations and lines of best fit to determine the relationship. They are then asked to make predictions about future tree growth under different greenhouse gas emissions, interpreting data from climate models to make these predictions.

This video and accompanying article describe the work of 2 scientists on Greenland's Petermann Glacier, who are attempting to collect data from beneath the glacier to determine if the temperature of the ocean water under the glacier is playing a role in the glacier's rapid retreat.

The Climate Momentum Simulation allows users to quickly compare the resulting sea level rise, temperature change, atmospheric CO2, and global CO2 emissions from six different policy options projected out to 2100.

This video highlights a variety of climate change research initiatives from scientists at the University of Colorado, Boulder. It describes the changing dynamics of Antarctic ice sheets and the impacts of reduced Arctic sea ice. The video illustrates the excitement of this research through interviews and video clips of scientists in the field.

This video features residents of Shishmaref, Alaska, plus environmental journalist Elizabeth Kolbert and scientist John Holdren, exploring the human impacts of global climate change.

This activity allows students to examine graphs of sea level rise data as well as global temperature data. They calculate amounts and rates of sea level rise for various time periods and answer questions discussing the data. They then compare the sea level rise trends to those in a graph of temperature data.
