Alliance for Climate Education -  https://acespace.org - 2016 initiative: Our Climate Our Future (http://www.ourclimateourfuture.org), a multimedia experience that educates young people about the science of climate change and empowers them to take action. It brings the ACE Assembly on climate science and solutions online, with dynamic animation, music, video and interactivity. Teacher resources:
    • Climate science, told through animation
    • Stories from young people across the country
    • Innovative climate solutions

American Association for the Advancement of Science (AAAS) Resources on Climate Change.

"Americans and Climate Change -- Closing the Gap Between Science and Action" - an interesting book that looks at American attitudes around this issue. It's a synthesis of insights and recommendations from the 2005 Yale School of Forestry & Environmental Studies Conference on Climate Change. © 2006 Free download.

American Geophysical Union (AG) position statement

Human Impacts on Climate
Adopted by Council December 2003
Revised and Reaffirmed December 2007
American Geophysical Union (AG) position statement Human Impacts on Climate Adopted by Council December 2003 Revised and Reaffirmed December 2007 Excerpt: The Earth's climate is now clearly out of balance and is warming. Many components of the climate system-including the temperatures of the atmosphere, land and ocean, the extent of sea ice and mountain glaciers, the sea level, the distribution of precipitation, and the length of seasons-are now changing at rates and in patterns that are not natural and are best explained by the increased atmospheric abundances of greenhouse gases and aerosols generated by human activity during the 20th century. Global average surface temperatures increased on average by about 0.6¡C over the period 1956-2006. As of 2006, eleven of the previous twelve years were warmer than any others since 1850. The observed rapid retreat of Arctic sea ice is expected to continue and lead to the disappearance of summertime ice within this century. Evidence from most oceans and all continents except Antarctica shows warming attributable to human activities. Recent changes in many physical and biological systems are linked with this regional climate change....
