Denial of scientific evidence and rejection of scientific methods is increasingly pervasive - in a new paper, written with Simon Attwood, @JosBarlow & @benphalan and available here: nature.com/articles/s4155…, we describe the creeping rise of #ExtinctionDenial

The @IPBES #GlobalAssessment Report published last year was met with considerable pushback and denial from media and political voices nature.com/articles/s4155… for whom #TransformativeChange & policy options to restore & protect #Biodiversity are anathema 2/8
Subsequently, articles challenging the scientific consensus that threats to biodiversity viewed at a global level (rather than cherry-picked local level) require urgent attention have become increasingly common e.g. recently humanprogress.org/article.php?p=… and perc.org/2020/07/06/aga… 3/8
Nach Lektüre des Klimapapiers der @FDP_Liberalen fdp.ch/fileadmin/user…: Will niemandem unterstellen. Aber ein paar Missverständnisse gibt es zu klären (1/12):
Z. 3-4: Klima und Artenschwund "eine bedeutende Herausforderung": wenn man @IPCC_CH #SR15 oder @IPBES #GlobalAssessment gelesen hat, kann man das nur als verharmlosend bezeichnen. (2/12)
Z 35: THG-Emissionen müssen "bis zweite Jahrhunderthälfte auf netto null". Seit @IPCC_CH #SR15 wissen wir: um Ziele des #ParisAgreement zu erreichen spätestens 2050, und reiche Länder müssen nach PA wie nach UNFCCC vorangehen. (3/12)
I’ve done more press in the past couple of weeks than I’ve done…ever. By a lot. And it mostly went well! HUGE thanks to some amazing teachers and role models. This thread is a few thoughts, tips, & reflections following the @IPBES #GlobalAssessment media blitz #SciComm [1/10]
All those years of #SciComm training paid off! I’m most grateful for the role playing, so I could see how I came across and adapt. Take training opportunities – you want this drilled into you so you can do it without thinking when the time comes [2/10]
This week's #GlobalAssessment on biodiversity warns that 1 million species face extinction due to human activity. Invasive species are cited as a main threat, as they move to new habitats, effectively tipping the scales & threatening native species. ow.ly/66GI50u6pKQ (1/4)
#InvasiveSpecies are considered one of the most dangerous threats to marine ecosystems worldwide, second only to habitat loss. Since the 1900s, scientists have documented a 20% decline in native species due to their impacts! #FridayFact ow.ly/IyuG50u6qdv (2/4)
Scientists say #InvasiveSpecies impacts will worsen as climate change allows shipping routes to open in places like the Arctic. They predict international shipping could increase between 240% & 1,209% by 2050 – creating new travel routes for many #HullFouling organisms. (3/4)
[1] Let me explain it for you in this thread. @IUCNRedList and their many partner organisations have been producing detailed assessments of species extinction risk in different taxonomic groups since 1994 (when the first comprehensive #RedList assessment of birds came out)
[2] Obviously we can't be at all sure that birds are typical, so it would have been wildly unsafe to go from "14% of birds are threatened" to "14% of all species are threatened". Since then, @IUCNRedList assessments have been done for an ever-expanding set of taxonomic groups...
[3] ...with the proportion threatened ranging from ~9% for bony fishes up over 60% for cycads. But the *average* level of threat has started to settle down now, at about 25%, and we now have estimates for lots of different vertebrate, invertebrate and plant groups...
The #IPBES7 #GlobalAssessment sounds an important alarm. At @TheWCS we have solutions to address it. bit.ly/2GZse9N
We must protect #intactforests🌲🌲
Forests are #biodiversity strongholds for 2/3 of all land-based plants and animals.
Plus, this a powerful and cost-effective solution to combat #climatechange. #IPBES7 #GlobalAssessment

In the ocean, we seek to safeguard coral species, reverse the decline of sharks and rays, steward the recovery of marine mammals and expand marine protected areas. #IPBES7 #GlobalAssesment wcs.org/our-work/solut…
Aujourd’hui, l’@IPBES a rendu public son #GlobalAssessment.

#IPBES #GlobalAssessement : le rapport montre que l’effondrement de la #biodiversité est en premier lieu dû aux changements d’utilisation des sols occasionnés par l’#agriculture. (2/5)
#IPBES #GlobalAssessement : les progrès politiques enregistrés concernent surtout l’adoption de textes, dont l’application fait défaut, ce qui plaide pour transférer une partie de l’attention politique vers leur mise en œuvre concrète. (3/5)
