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

This short video from Climate Central explains the technology used to monitor changes in Arctic sea ice. Long-term tracking (since the late 1970's) shows Arctic sea ice has been on a steady decline and this could have significant implications for global temperatures.

This visualization, from the US Geological Survey, provides a simple schematic of the various pathways that water can take as it cycles through ocean, lakes, atmosphere, surface and ground.

This video follows Bermuda scientists into the field as they collect data that documents a warming trend in ocean temperatures. BIOS Director Tony Knapp discusses some of the impact of warming temperatures on sea levels, storms, and marine ecosystems.

This narrated slideshow describes the impact of sea level rise on Tuvalu, one of the low-lying island nations in the South Pacific. As the frequency and intensity of floods and cyclones increases, the island is shrinking and saltwater intrusion is affecting local food production on the plantations. As a result, many residents are moving off the island to New Zealand, where they face major cultural changes.

The NOAA Sea Level Trends map illustrates U.S. regional and some international trends in sea level, with arrows representing the direction and magnitude of change. Students can investigate sea level changes around the U.S. and some worldwide using an interactive map interface with supporting data plots and tables.

This video and accompanying essay review the impacts of rising surface air temperatures and thawing permafrost on ecosystems, geology, and native populations in Alaska.

This static image from NOAA's Pacific Marine Environmental Laboratory Carbon Program offers a visually compelling and scientifically sound image of the sea water carbonate chemistry process that leads to ocean acidification and impedes calcification.

This video shows some of the most dramatic fluctuations to our cryosphere in recent years, using visuals created with a variety of satellite-based data.

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).
