Many thousands of scientists have already signed the World Scientists’ Warning to Humanity, and we invite all scientists and social scientists around the world to join them.   In order to allow concerned and informed non-scientist individuals and organizations to become involved, we have added two more categories to display Our Supporters.  You are welcome to view our lists of current supporters, but please add your support.  Please Sign under one of the following categories as well.


Please share the Scientists’ Warning widely with your contacts and social media.
