The Alliance of World Scientists (AWS)

The AWS is a new international assembly of scientists, which is independent of both governmental and non-governmental organizations and corporations. We submit, that in order to prevent widespread misery caused by catastrophic damage to the biosphere, humanity must practice more environmentally sustainable alternative to business-as-usual. Our vital importance and role comes from scientists' unique responsibility as stewards of human knowledge and champions of evidence-based decision-making. The main goal of the AWS is to be a collective international voice of many scientists regarding global climate and environmental trends and how to turn accumulated knowledge into action. Other organizations do laudable work toward this goal, but to our knowledge, AWS is the only independent, grass-roots organization comprised of scientists from around the world committed to the well-being of humanity and the planet.

When you endorse the scientists’ warning article, you will have the option of including your email address for occasional communication or additional collaboration as part of the AWS.
