Virtueller Wochenendausflug

SWR Expedition in die Heimat: Die Loreley, der Fels am Strom.

Bevor wir in die Pfalz gezogen sind, haben André und ich über sechs Jahre oberhalb des Mittelrheintals gewohnt und sind in der Zeit den größten Teil des Rheinsteigs gewandert. Die Köngisetappe, auf der die Moderatorin hier unterwegs ist, sind wir gleich mehrmals gelaufen, gern auch mit Besuch aus Nah und Fern.

Zuletzt war ich diesen Sommer im Mittelrheintal wandern. Auf der Loreley war allerdings gerade eine riesige Baustelle, weil das Areal völlig umgestaltet wird. Schade, es ist nicht mehr so beschaulich wie früher… aber Busladungen an Touristen verlangen nach Infrastruktur.

Dennoch: Das Weltkulturerbe Oberes Mittelrheintal ist immer (wieder) eine Reise wert!

“Extremely likely” means a probability between 95 and 100%

If baffles me that there are still people denying the human influence on climate even though many studies show that it is extremely likely. I mean, if it is extremely likely that you will sustain serious injuries or die when jumping out of a third floor window, would you take the chances and jump?!

Part of the problem seems to be that many people don’t know enough about statistics, and that some politicians don’t trust the scientific method.

NPR The Two-Way: Massive Government Report Says Climate Is Warming And Humans Are The Cause.

“It is “extremely likely” that human activities are the “dominant cause” of global warming, according to the the most comprehensive study ever of climate science by U.S. government researchers.

The climate report, obtained by NPR, notes that the past 115 years are “the warmest in the history of modern civilization.” The global average temperature has increased by about 1.8 degree Fahrenheit over that period. Greenhouse gases from industry and agriculture are by far the biggest contributor to warming.

The findings contradict statements by President Trump and many of his Cabinet members, who have openly questioned the role humans play in changing the climate.

“I believe that measuring with precision human activity on the climate is something very challenging to do,” EPA Administrator Scott Pruitt said in an interview earlier this year. “There’s tremendous disagreement about the degree of impact.”

That is not consistent with the conclusions of the 600-plus page Climate Science Special Report, which is part of an even larger scientific review known as the fourth National Climate Assessment.
[…]
The report states that the global climate will continue to warm. How much, it says, “will depend primarily on the amount of greenhouse gases (especially carbon dioxide) emitted globally.” Without major reductions in emissions, it says, the increase in annual average global temperature could reach 9 degrees Fahrenheit relative to pre-industrial times. Efforts to reduce emissions, it says, would slow the rate of warming.
[…]
The report has been submitted to the Office of Science and Technology Policy at the White House. Trump has yet to choose anyone to run that office; it remains one of the last unfilled senior positions in the White House staff.”

“The good news is the void is there.”

NPR The Two-Way: Scientists Say They’ve Found Hidden Space In Great Pyramid Of Giza.

“Tayoubi explains that his team installed sheets of muon-detecting film in a lower-level room of the pyramid known as the Queen’s Chamber. The goal was to test whether they could use muons to accurately discern two well-known rooms located above: the King’s Chamber and Grand Gallery.

They saw those rooms but, to their surprise, they found an additional large space as well.”

Deutsche Welle: Hohlraum in Cheops-Pyramide entdeckt. “Seit zwei Jahren durchleuchten internationale Forscherteams mit Strahlungsdetektoren die Cheops-Pyramide. Jetzt feierten sie den Durchbruch: Sie entdeckten einen riesigen Hohlraum in der größten Pyramide in Gizeh.”

Ecology meets Art

“Ernst Heinrich Philipp August Haeckel (16 February 1834 – 9 August 1919) was a German biologist, naturalist, philosopher, physician, professor, marine biologist, and artist who discovered, described and named thousands of new species, mapped a genealogical tree relating all life forms, and coined many terms in biology”. He was heavily influenced by Alexander von Humboldt, about whom I recently read a book called The Invention of Nature by Andrea Wulf (highly recommended, by the way).

Haeckel is most well-known for his incredibly detailed and beautiful drawings of radiolarians and other Kunstformen der Natur (art forms in nature). Recently, a new book with his drawings was published:

The Guardian: Ernst Haeckel: the art of evolution – in pictures.

“The influential evolutionary scientist, who coined such terms as ‘stem cell’ and ‘ecology’, was also a virtuoso illustrator. The editor of a new book celebrating this work introduces some highlights.”

Creative Review: Feast your eyes on the art of Ernst Haeckel. “A new book from Taschen compiles 450 drawings, watercolours and sketches of living organisms by artist and biologist Ernst Haeckel.”

The book is fairly costly, but if you prefer a cheaper, sort of do-it-yourself version, there’s always the Art Forms in Nature: Coloring Book. ;-)

Und für Menschen, die der deutschen Sprache mächtig sind, existiert eine HTML-Version von Kunstformen der Natur (vollständige elektronische Faksimile-Ausgabe). Dort kann man sich einzelne Tafeln anschauen oder zum Ausdrucken herunterladen. Es gibt auch eine tar-Datei mit allen Tafeln (16MB) sowie das komplette Buch als PDF (272MB).
