This video shows where and how ice cores are extracted from the West Antarctic Ice Sheet (WAIS), cut, packaged, flown to the ice core storage facility in Denver, further sliced into samples, and shipped to labs all over the world where scientists use them to study indicators of climate change from the past.
TreeFlow is a comprehensive web resource for tree-ring reconstructions of streamflow and climate, providing easy access to reconstruction data as well as information about how the data were developed, and can be used. Originally developed by researchers at the Climate Assessment for the Southwest, TreeFlow has a growing collection of tree ring constructions for river basins throughout the Western United States.
Cal-Adapt is a web-based climate adaptation planning tool developed in part by the University of California, Berkeley's Geospatial Innovation Facility for the State of California. Cal-Adapt allows users to identify potential climate change risks in specific geographic areas throughout the state. Users can either query by location, or click on an interactive map to explore what climate impacts are projected to occur in their area of interest.
The Southwest Climate Change Network is a virtual community for scientists, other experts, decision makers, and the public to share information on climate change and collaborate on solutions. The site provides static and dynamic content and encourages readers to engage with each other and the scientists behind the site and ask questions about what matters to them when it comes to climate in the Southwest.
The longest instrumental climate records date back only about 100 years in the Southwest, a timeframe that likely does not capture the full range of climate variability. Extending the record to earlier times provides additional information on the length and severity of past droughts. This tool created by the Climate Assessment for the Southwest allows users to visualize the climate variability during the past 1,000 years or so in each climate division in Arizona and New Mexico.
The Alaska Center for Climate Assessment and Policy has an archive of all its webinars on a variety of climate issues in the Alaska and the Arctic. The webinar series is also ongoing with new speakers and topics scheduled regularly.
This activity uses geophysical and geochemical data to determine climate in Central America during the recent past and to explore the link between climate (wet periods and drought) and population growth/demise among the Maya. Students use ocean drilling data to interpret climate and to consider the influence of climate on the Mayan civilization.
This activity engages learners to make a model of sediment cores using different kinds of glass beads and sand. They learn how to examine the types, numbers, and conditions of diatom skeletons in the model sediment cores and tell something about the hypothetical paleoclimate that existed when they were deposited. The students get to be climate detectives.
In this activity, students make a model sea floor sediment core using two types of buttons to represent fossil diatoms. They then compare the numbers of diatom fossils in the sediment at different depths to determine whether the seas were free of ice while the diatoms were alive.
In this activity, students chart temperature changes over time in Antarctica's paleoclimate history by reading rock cores. Students use their data to create an interactive display illustrating how Antarctica's climate timeline can be interpreted from ANDRILL rock cores.
