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) when a sudden, enormous influx of carbon flooded the ocean and atmosphere for reasons that are still unclear to scientists. The PTEM is used as an analog to the current warming occurring.
This video segment, from the 'Earth: The Operators' Manual' featuring climate expert Richard Alley, shows how ice cores stored at the National Ice Core Lab provide evidence that ancient ice contains records of Earth's past climate - specifically carbon dioxide and temperature.
This video illustrates how atmospheric particles, or aerosols (such as black carbon, sulfates, dust, fog), can affect the energy balance of Earth regionally, and the implications for surface temperature warming and cooling.
With this carbon/temperature interactive model, students investigate the role of atmospheric carbon in the greenhouse effect using a relationship between atmospheric carbon dioxide and global temperature.
In this video, students see how data from the ice core record is used to help scientists predict the future of our climate. Video features ice cores extracted from the WAIS Divide, a research station on the West Antarctic Ice Sheet.
Over 360 authors from 45 countries contributed to this comprehensive appraisal of the Earth’s climate. Observations from pole-to-pole show climate patterns such as La Niña and El Niño contributed to some climate events this year. Trends consistent with manmade climate change over the last 50 years are also continuing. These include warming temperatures, melting glaciers and saltier seas, which are related to rising atmospheric greenhouse gas concentrations.
Weather and Climate Extremes in a Changing Climate
June 18, 2008
An assessment in the state of knowledge concerning changes in weather and climate extremes in North America and U.S. territories. Changes in extreme weather and climate events have significant impacts and are among the most serious challenges to society in coping with a changing climate.
