World Scientists’ Second Warning to Humanity

A total of 15,364 of the world’s scientists co-signed a warning to humanity of the imminent and dire threat to the earth posed by human-induced climate change, biodiversity losses, and other acts of environmental destruction. This is the second warning. The first was issued in 1992. This new warning reflects growing concerns as nations, including the United States, have failed to make sufficient progress in dealing with these problems. The warning is in the form of an article in the November 2017 issue of Bioscience which uses graphs to show the decline in nine key environmental issues.  Among the 15,000 scientists signing on to support the article was Dr. Betsy Herbert, who signed as President of the Santa Cruz Mountains Bioregional Council. This is the greatest number of scientists to ever co-sign and support a scientific article. You can read the article here.
