Over 15,000 scientists hailing from more than 180 countries just issued a dire warning to humanity:
"Time is running out" to stop business as usual, as threats from rising greenhouse gases to biodiversity loss are pushing the biosphere to the brink.
The new warning was published Monday in the international journal BioScience, and marks an update to the "World Scientists' Warning to Humanity" issued by nearly 1,700 leading scientists 25 years ago.
The 1992 plea, which said Earth was on track to be "irretrievably mutilated" baring "fundamental change," however, was largely unheeded.
