If @realDonaldTrump really thinks that nothing can be done against global warming, maybe he could understand this: "nine top scientists, the members of @WBGU_Council as comic-book heroes, show us that we can beat the heat - and how to do it! wbgu.de/en/comics/comi… (free pdf)
... and of course, this is also very helpful to understand and fight the Whitehouse effect: the #Madhouse effect (@MichaelEMann) theguardian.com/environment/cl…
The Great Transformation comic ( wbgu.de/en/comics/comi… #trafocomic ) and the Madhouse effect are both also available in German (and the GT also in French, Korean, and partly, in Spanish): see die-grosse-transformation.de . German version of Madhouse effect: dgs-franken.de/medien/tollhau…
My own view is that gradualism followed by a final exclamation point is a very likely extinction scenario, both for dinosaurs — and for humans. Indulge me in long thread that ends with meditations on #TransformationOfTheHuman... 1/
Today, we are clearly in the middle of what scientists refer to “The Sixth Great Extinction,” akin in many respects to the Fifth one, that killed the dinosaurs, and whose causes are debated in that @TheAtlantic article. So: when did the SGE begin, and how will it end? 2/
First, a small methodological points: geological eras are generally demarcated by either species die offs and emergences and/or some other geological market. This is the debate over how to date the start of the anthropocene, which I discussed here: smallprecautions.blogspot.com/2012/06/period… 3/
Though I am really glad that #arsenic contamination of #groundwater in India, and specially #WestBengal is getting the attention it deserves, there is a major issue that needs wider discussion.
There is a simplistic argument that arsenic naturally occurs in the #Gangetic belt, the author uses the term “#geological curse”. If this is the case, why is heavy #arsenic contamination being reported from #Jharkhand and #Chattisgarh in Central India?
A possible answer to that may be traced to this MIT paper that was published in @NatureGeosci on #anthropogenic influence on #groundwater #arsenic contamination in #Bangladesh nature.com/articles/ngeo6…
