In “Second Notice” to world, top scientists warn of global environmental disaster; call for more PAs
Scientists have issued a second warning of impending doom for the natural world if humanity does not make significant changes in how we treat the planet. The warning is presented in a paper published this week in Bioscience, and serves as a follow-up on a similar declaration by scientists in 1992.
The first “World Scientists’ Warning to Humanity” was authored in 1992 by the Union of Concerned Scientists (UCS) and signed by 1,700 scientists, including most living Nobel laureates in the sciences. It called out the “collision course” between humans and the natural world, pointing to evidence of “critical stress” to the planet’s various systems, from the ocean and atmosphere to forests and soil. It describes how this stress manifested in depletion of ozone, water, fish stocks, soil productivity and biodiversity.
