Earth’s climate future and you
Use the ACS Climate Science Toolkit, www.acs.org/climatescience, toreview or learn the basic concepts of climate science.
Expand your knowledge of climate science areas of special interestwith print and media resources.
Engage your friends and colleagues in deliberative discussion on thescience of global climate change.
Take advantage of opportunities to present the science of globalclimate change for civic, religious, educational, and governmentalgroups.
Take a public stand on the issues related to the undesiredconsequences of climate change and the need for mitigation andadaptation. Encourage and support your local and nationalgovernmental representatives to do the same.
