project_arcc | archivists responding to climate change
"Founded on Earth Day in 2015, ProjectARCC is a task force of archivists striving to motivate the archival community to affect climate change. We believe that archivists, those responsible for the preservation of history for future generations, should be as passionate and concerned about preserving a habitable and safe planet for future generations."

Apocalypse when? (Not) thinking and talking about climate change | Discover Society
"Psychologists are identifying countless psychological ‘barriers’ that obstruct behaviour change despite knowledge about anthropogenic ecological degradation, that include perceptual, cognitive, emotional, interpersonal and group processes (see Robert Gifford’s overview). Some researchers, inspired by psychoanalysis, study how defence mechanisms act as barriers to action in the context of ecological crisis. Originally conceptualized by Freud, defence mechanisms are psychological processes aimed at avoiding, or protecting one’s self from, experiences of emotional distress, destructive impulses, or threats to self-esteem. Many – like repression, regression, projection and denial – have entered into everyday language."

When did the Anthropocene begin? A mid-twentieth century boundary level is stratigraphically optimal
"We evaluate the boundary of the Anthropocene geological time interval as an epoch, since it is useful to have a consistent temporal definition for this increasingly used unit, whether the presently informal term is eventually formalized or not. Of the three main levels suggested – an ‘early Anthropocene’ level some thousands of years ago; the beginning of the Industrial Revolution at ∼1800 CE (Common Era); and the ‘Great Acceleration’ of the mid-twentieth century – current evidence suggests that the last of these has the most pronounced and globally synchronous signal. A boundary at this time need not have a Global Boundary Stratotype Section and Point (GSSP or ‘golden spike’) but can be defined by a Global Standard Stratigraphic Age (GSSA), i.e. a point in time of the human calendar. We propose an appropriate boundary level here to be the time of the world's first nuclear bomb explosion, on July 16th 1945 at Alamogordo, New Mexico; additional bombs were detonated at the average rate of one every 9.6 days until 1988 with attendant worldwide fallout easily identifiable in the chemostratigraphic record. Hence, Anthropocene deposits would be those that may include the globally distributed primary artificial radionuclide signal, while also being recognized using a wide range of other stratigraphic criteria. This suggestion for the Holocene–Anthropocene boundary may ultimately be superseded, as the Anthropocene is only in its early phases, but it should remain practical and effective for use by at least the current generation of scientists."
