In 1992, the Union of Concerned Scientists (UCS) in Washington, D.C. along with over 1,700 scientists from around the world, including the majority of then-living Nobel laureates in the sciences, drafted and signed the first World Scientists’ Warning to Humanity. That warning is still available at the UCS website, but is also presented here for you to read and share.
On its 25th anniversary (in 2017), a group of scientists looked back at that first warning to evaluate humanity’s response. What they found was most distressing. With the exception of curtailing depletion of the ozone layer protecting life from the sun’s damaging UV radiation, humanity had failed to make progress in solving the challenges originally documented. Instead things had gotten far worse.
This group formed the Alliance of World Scientists (AWS). Their study, entitled:
World Scientists’ Warning to Humanity: A Second Notice,
was published in the prestigious journal BioScience, available here. An abstract or summary of this Second Notice can be viewed as a pdf file here.
There is an excellent video embedded below which goes through the paper.
