In this video segment, a team of scientists seeks evidence to support their hypothesis that atmospheric warming -- either now or in the past -- may explain why water has formed beneath the West Antarctic ice sheet, causing ice streams that flow much more quickly than the rest of the ice sheet. This phenomenon has important implications for potential sea level rise.
In this activity, students use historical data showing the extent of the Grinnell Glacier in Glacier National Park to estimate when the glacier will melt completely. Students use historical imagery showing the extent of the Grinnell Glacier in Glacier National Park at a series of different times to estimate when the glacier will melt completely.
In this Climate Central-produced video scientists in the state of Washington explain a variety of factors related to overall warming trends that have led to increased forest fires in the state and the resulting impacts on habitats and the state economy.
In this activity about climate change on the Antarctic Peninsula, learners investigate environmental changes in the living and nonliving resources of Antarctic peninsula and the impact of these changes on Adélie penguin communities. The activity stresses the importance of evidence in the formulation of scientific explanations.
This video describes the role that dendrochronology plays in understanding climate change, especially changes to high elevation environments at an upper tree line. Dendrochronologists from the Big Sky Institute sample living and dead trees, describe how correlations between trees are made, and explain how tree cores record climate changes.
This interactive visualization describes how climatologists obtain and interpret evidence from the Greenland Ice Sheet in an effort to piece together a picture of Earth's distant climate history. Resource describes how glaciers form and how they can be used to collect ancient atmospheric data. The issues analyzed in the data collection are particularly good in showing how science is done in the field.
This video shows the potential of dendrochronology (tree ring study) to shed light on climatic conditions of the past. Scientists at Columbia University's Lamont-Doherty Earth Observatory read the growth rings of ancient trees to understand the history and workings of the monsoon. In addition, historical accounts are correlated with data from tree rings to better understand these events.
This short video features the Alaska Lake Ice and Snow Observatory Network (ALISON project), a citizen science program in which 4th and 5th graders help scientists study the relationship between climate change and lake ice and snow conditions.
