Teachers Receive Climate Poster

3,000 Posters Printed

An AAPG poster titled "What Makes Climate Change," showing climate change drivers and scale of climate change, has been made available to selected U.S. teachers and community leaders. About 3,000 posters were printed.

Created and written by members William E. Harrison and Lee C. Gerhard, the poster offers an eye-catching design by Patricia Acker of the Kansas Geological Survey and highlights explanations of the climate drivers. They include Earth's position, ocean currents, polar wobbling, variable sun intensity, long ocean tide and current cycles, volcanoes, weathering, mountain building, solar flares, El Niño, meteorite impact and human intervention.

An AAPG poster titled "What Makes Climate Change," showing climate change drivers and scale of climate change, has been made available to selected U.S. teachers and community leaders. About 3,000 posters were printed.

Created and written by members William E. Harrison and Lee C. Gerhard, the poster offers an eye-catching design by Patricia Acker of the Kansas Geological Survey and highlights explanations of the climate drivers. They include Earth's position, ocean currents, polar wobbling, variable sun intensity, long ocean tide and current cycles, volcanoes, weathering, mountain building, solar flares, El Niño, meteorite impact and human intervention.

In a letter accompanying the poster, AAPG President Patrick J.F. Gratton notes:

"The science of climate change has progressed rapidly in the past few years as more research demonstrates the effects of solar and orbital drivers. As geologists, we are obliged to take the larger view of the universe, and place change into the longer perspective of geologic time. In doing so, it became apparent that there is a relationship between drivers and the amount of change that occurs. The enclosed chart and the accompanying text reprint is sent to you in the hope that it will assist you in your teaching of the science of climate change on Planet Earth."

Also made available to teachers was the introductory text from the AAPG Studies in Geology #47, Geological Perspectives of Global Climate Change, edited by Gerhard, Harrison and Bernold "Bruno" Hanson, from which the poster was derived.

Gerhard and Harrison, both past presidents of AAPG's Division of Environmental Geosciences, said the chart attempts to bring the latest in science to discussion of climate change, particularly including the role of solar and orbital variability.

The project was funded by both AAPG and the AAPG Foundation.
