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.

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

In this activity, students examine NASA satellite data to determine if sea surface temperature has reached a point that would cause coral bleaching in the Caribbean.

This audio slideshow examines the changes in the ecosystem that will occur to the Arctic due to increasing temperatures and disappearing sea ice.

This is a photo essay linked to a New York Times story about climate-related stressors on forests -- including mountain pine beetles, forest fires, forest clearance, and ice storms -- and the importance of protecting forests as an important carbon sink.

In this lab activity, students use brine shrimp as a proxy for krill to study how environmental factors impact behavioral responses of krill in the unique environment of Antarctica.

This is a National Geographic short video that briefly describes how succulent plants in the South African Karoo biome are dying off due to changes in climate.

This video looks at the impact of changing climate on animal habitats around the world, showing how different creatures are responding to changing temperatures and precipitation patterns.

This 3-part interactive and virtual lab activity examines the life cycle of the sea urchin, and how the increasing acidity of the ocean affects their larval development.

In this video, a team of paleontologists, paleobotanists, soil scientists, and other researchers take to the field in Wyoming's Bighorn Basin to document how the climate, plants, and animals there changed during the Paleocene- Eocene Thermal Maximum (PETM). During this time a sudden, enormous influx of carbon flooded the ocean and atmosphere for reasons that are still unclear to scientists. The PETM is used as an analog to the current warming. The scientists' research may help inform our understanding of current increases in carbon in the atmosphere and ocean and the resulting impact on ecosystems.
