The Science of Climate Earth’s climate future and you Use the ACS Climate Science Toolkit, www.acs.org/climatescience, to review or learn the basic concepts of climate science. Expand your knowledge of climate science areas of special interest with print and media resources. Engage your friends and colleagues in deliberative discussion on the science of global climate change. Take advantage of opportunities to present the science of global climate change for civic, religious, educational, and governmental groups. Take a public stand on the issues related to the undesired consequences of climate change and the need for mitigation and adaptation. Encourage and support your local and national governmental representatives to do the same. American Chemical Society
