A short video on the causes of ocean acidification and its effects on marine ecosystems.

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 documents the scope of changes in the Arctic, focusing on the impacts of warming and climate change on the indigenous Inuit population.

A short video on how changing climate is impacting the ecosystem and thereby impacting traditional lifestyles of the Athabaskan people of 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.

This is a polar map of permafrost extent in the Northern Hemisphere. A sidebar explains how permafrost, as it forms and later thaws, serves as both a sink and source for carbon to the atmosphere. Related multimedia is a slideshow of permafrost scientists from U. of Alaska, Fairbanks, collecting permafrost data in the field.

This video documents the challenges that climate change presents for four specific Arctic predators: polar bears, Arctic foxes, beluga whales and walruses.

In this video, the mountain pine beetle problem is explained by two scientist. Their research investigates the beetle and how climate change is impacting its spread.

This clickable visualization demonstrates the catastrophic effect that follows the removal of a key producer or consumer in the Arctic food chain.

In this video a scientist explains how DNA extracted from ancient tree remains provides insights about how trees/plants have adapted, over time, to changes in CO2 in the atmosphere. Her lab research investigates changes in plant genotypes under experimental conditions that simulate potential changes in CO2 levels in the future.
