AI synopsis
The consensus among discussions is that current extinction rates are alarmingly high, with mentions of biodiversity loss, the importance of studies like Barnosky et al., and debates about whether we are already in a sixth mass extinction, emphasizing both scientific curiosity and concern for environmental impact.
Most discussions acknowledge the possibility that we are experiencing a significant biodiversity crisis, though some are cautious about labeling it a full mass extinction.
Posts show high curiosity about current extinction rates and the potential for a sixth mass extinction, indicating strong engagement with the topic.
Many discussions reference specific studies, such as Barnosky et al. 2011, and debate whether current rates meet the criteria for a mass extinction, demonstrating deep engagement.
The discussions highlight concerns about the future of biodiversity and emphasize the importance of understanding extinction trends, suggesting a moderate societal impact.
@jgeldmann @JMBecologist As percentage of species extinct, we are nowhere near a mass extinction. As speed of species extinction, we are heading towards one. But it will take several centuries at current extinction rates to be realised. See https://t.co/PqSLYl4Edt.

@curtisjohnson70 Extinction rates are awfully hard to constrain, both in the geological record and in the modern--though some have tried, i.e. Anthony Barnosky. From his paper "Has the Earth’s sixth mass extinction already arrived?" https://t.co/OBvZAkpQWV

@MichaelGuillon @lemondefr @courrierinter 4) Mais l’article de Barnosky et al. (https://t.co/p70gSUlv2T) dit: "the recent loss of species is … serious but does not yet qualify as a mass extinction in the palaeontological sense of the Big Five. In historic times we have actually lost only a few % of assessed species".

Has Earth arrived at its sixth mass extinction already? We are experiencing a massive biodiversity crisis. Is it happening on the scale of the Big 5 Massive Extinctions? Read to find out! https://t.co/tyoVYMcVJm #BIOL2300_002_assignments
Some biologists believe that another mass extinction may occur. A mass extinctions occurs when the Earth loses over 75% of its population in a short time. DOI:10.1038/nature09678 #BIOL2300_002_assignments

@DrJamesThomka On this topic my students & I found the Barnosky et al. (doi:10.1038/nature09678) paper helpful, as well as Jonathan Payne's talk "The Sixth (Modern) Mass Extinction – A Geologic Perspective": https://t.co/5X7acIlbFF

Both groups accept evidence of a process, that “current [extinction] rates would produce Big-Five-magnitude mass extinctions in the same amount of geological time that we think most Big Five extinctions spanned” (55). https://t.co/SSHnkj7itU
