Warning to Humanity: A Second Notice

Please join me, and several thousand scientists from over 100 countries, in becoming a co-signatory on the article World Scientists' Warning to Humanity: A Second Notice (Ripple et al, 2017), which marks the 25th anniversary of the first notice, which was initiated by the Union of Concerned Scientists. The deadline for signatory is September 19th 2017. 

Extract:
"Twenty-five years ago, the Union of Concerned Scientists and more than 1500 independent scientists, including the majority of living Nobel laureates in the sciences, penned the 1992 "World Scientists' Warning to Humanity". These concerned professionals called on humankind to curtail environmental destruction and cautioned that “a great change in our stewardship of the Earth and the life on it is required, if vast human misery is to be avoided.” In their manifesto, they showed that humans were on a collision course with the natural world. They expressed concern about current, impending, or potential damage on planet Earth involving ozone depletion, freshwater availability, marine fishery collapses, ocean dead zones, forest loss, biodiversity destruction, climate change, and continued human population growth. They proclaimed that fundamental changes were urgently needed to avoid the consequences our present course would bring."

"On the 25th anniversary of their call, we look back at their warning and evaluate the human response by exploring available time-series data. Since 1992, with the exception of stabilizing the stratospheric ozone layer, humanity has failed to make sufficient progress in generally solving these foreseen environmental challenges, and alarmingly, most of them are getting far worse. Especially troubling is the current trajectory of catastrophic anthropogenic climate change due to rising GHGs from burning fossil fuels (Hansen et al. 2013), deforestation (Malhi et al. 2008), and agricultural production--particularly from farming ruminants for meat consumption (Ripple et al. 2014). Moreover, we have unleashed a mass extinction event, the sixth in roughly 540 million years, wherein many current life forms could be annihilated or at least committed to extinction by the end of this century."
