In review, AAAS publishes six peer-reviewed journals. Science, the premier global science weekly; Science Signaling, the leading journal of cell signaling and regulatory biology; Science Translational Medicine, integrating medicine, engineering, and science to promote human health; Science Advances, an innovative and high-quality open-access journal for all the sciences; Science Immunology, research articles that report critical advances in all areas of immunological research, including important new tools and techniques; and Science Robotics, original, peer-reviewed, science- or engineering-based research articles that advance the field of robotics.

For example, in 2006, they wrote, “The scientific evidence is clear: global climate change caused by human activities is occurring now, and it is a growing threat to society…The pace of change and the evidence of harm have increased markedly over the last five years. The time to control greenhouse gas emissions is now.”
