This just makes no sense. Uncertainty about temperature ranges should increase dramatically when you go back to 1880 instead of 1950.

You can't write things like that and think that the skeptics are just out to get you and wish you harm. It's just not plausible in any way, shape or form.

Ich denke bei der Gegend immer an den englischen Namen "Afar Triangle".

Die Kreditblase ist heute wahrscheinlich um ein vielfaches größer als 2008. Das wird alles nicht schön ausgehen.

Wichtigster Unterschied zu 2008 ist, dass die schlechteste Bewertung nicht mehr D, sondern B ist.

Man kann es sich nicht ausdenken.

Berge sind keine Senken, aber .... ansonsten schon. Ja. ;)

Therefore it's not credible that the desert/barren land fraction has stayed the same over the last 10.000 years. There is very good evidence that the earth, especially the north, was it its coldest and driest phase of the holocene in the 1800s and thus also at the least habitable land fraction.

These numbers are not credible, because much of the Sahara was, if not entirely green, then at least a much smaller desert than today.

This is mostly due to astronomical reasons creating warmer summers in the northern hemisphere (as currently in the south).

Cyanide oder Quecksilber hat man aber nicht mit seltenen Erden, sondern praktisch nur in Goldminen um kleine Goldmengen aus dem Gestein zu konzentrieren.

Sodium ion batteries are a technology whose time has come. They were around in the 1970/80s alongside lithium ion batteries, it's just that lithium easier to handle and got more energy density. But now the issue isn't energy density anymore, it's how much can be produced with the resources we have.

Ja, das Ulmener Maar ist etwa 10.900 Jahre alt. (Also 8.900 BC)

Der Laacher See war aber mit *sehr* großem Abstand die größte Eruption.

Kam so überraschend, dass es noch nichtmal Flugwarnungen gab, bis ein Youtuber die Behörden darauf hingewiesen hat.
