This video features changes in the land, sea, and animals that are being observed by the residents of Sachs Harbour, Northwest Territories, Canada â many of whom hunt, trap, and fishâbecause of their long-standing and intimate connection with their ecosystem. Scientists interview the residents and record their observations in order to deepen our understanding of climate change in the polar region. Background essay and discussion questions are included.
This short cartoon video uses a simple baseball analogy (steroid use increases probability of hitting home runs) to explain how small increases in greenhouse gases can cause global temperature changes and increase the probability of extreme weather events.
This video examines the thawing of permafrost due to changes in climate and shows examples of the impacts that warming temperatures have on permafrost in the Arctic, including the release of the greenhouse gas methane. Dramatic results are shown, including sink holes forming on the landscape and beneath buildings, roads, and other infrastructure, causing some communities to relocate.
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).
This video highlights a variety of current climate change research initiatives from scientists at the University of Colorado, Boulder. It describes the changing dynamics of Antarctic ice sheets and glaciers and the impacts of reduced Arctic sea ice on people, animals, and global albedo and sea levels, while providing a glimpse of the excitement of this field research through interviews and video clips of scientists in the field.
This is a collection of five short videos - The Arctic Ice Cap, Sampling the Ice, Arctic Fisheries, Natives Feel Effect and Arctic Energy -- that can be played separately or in sequence. They show how climate change is affecting fishing, native populations and access for the oil and gas industry in the Arctic. The videos include personal reflections by writers Andrew C. Revkin and Simon Romero , scientists and residents about their experience of the impacts of the climate change in the Arctic.
This is a video that documents the reflections of members of the Steger International Polar Expedition team reunited at the 25th anniversary of their landmark trek to the Arctic, and how climate change has made their trek difficult to replicate.
This video features CU Boulder Professor Jeff Mitton and his research team, who study the effects of mountain pine beetle infestations on the forest ecology in the Rocky Mountains. They explain the pine beetle life cycle and how they attack trees. An outlook into the future is also provided.
C-Learn is a simplified version of the C-ROADS simulator. Its primary purpose is to help users understand the long-term climate effects (CO2 concentrations, global temperature, sea level rise) of various customized actions to reduce fossil fuel CO2 emissions, reduce deforestation, and grow more trees. Students can ask multiple, customized what-if questions and understand why the system reacts as it does.
