the permian extinction is obviously the most interesting.
this is, obviously, nonsense.

"the cause of the permian extinction is unknown.
other parts of the country."

the petm is worrisome, but the event that really worries me is the end permian.

this consists mainly of permian red-bed soils, but there are also lighter sandy marl soils.
jedná se zejména o permské červenky, ale i o lehčí opukové půdy.

he says that evidence points to the cause of the permian extinction being prolonged and violent eruptions from the siberian traps, a huge region of volcanic rock.

as you point out, the petm was nasty, but the end permian mass extinction was the big one, extinguishing on the order of 90 percent of species existing at that time.

if this work holds up, it may help explain the strong positive feedback of past apparent methane catastrophes including the paleocene-eocene thermal maximum and the end permian mass extinction, i think.

if we take the end permian event, and add in a more rapid triggering event, a buildup of ice age methane hydrates, and a sun that is five percent or so hotter, what do we end up with?

link: it is the specific natural conditions in the Žatec hop-growing area that provide the basis for the uniqueness of "Žatecký chmel" (cf. paragraph 4.2). this area is protected to the north-west by the ore mountains, the doupov hills and the bohemian uplands, which produce a rain shadow. the total annual rainfall in this area is therefore only about 450 mm. the timing of the rainfall is, however, favourable to the development of the hops (average rainfall during the growing period is about 260 mm). the average annual temperature is 8-9 °c (but 14-16 °c during the growing period). the quality of the hops is determined not only by the climatic conditions but also by the area's soil. this consists mainly of permian red-bed soils, but there are also lighter sandy marl soils. the growth and development of the hops is also influenced by the situation of the hop gardens, which is determined in particular by the altitude (200-500 metres above sea level) and the position within the lie of the land, the gradient and exposure to the different points of the compass. the hop gardens are located in particular in broad, open valleys with a free airflow which are sufficiently sheltered from strong west and north winds. the hops would not achieve such quality or yields in other areas, where these conditions do not exist. the environment has an influence in particular on the content and growth of the hops. the conditions described above (combination of average rainfall, temperatures, soil profiles, altitude and light) are unique to the Žatec hop-growing area. other hop-growing areas in the world will always differ in respect of certain of the basic conditions (e.g. higher rainfall, higher average temperatures, shorter average length of day/daylight during the growing period).
souvislosti: základem jedinečnosti Žateckého chmele (viz 4.2) jsou specifické přírodní podmínky v Žatecké chmelařské oblasti. tato oblast je od severozápadu chráněna krušnými horami, doupovskými vrchy a Českým středohořím, které vytvářejí tzv. dešťový stín. proto zde průměrný roční úhrn srážek představuje pouze okolo 450 mm. rozložení srážek je však pro vývoj chmele příznivé (za vegetační období jsou průměrné srážky kolem 260 mm). průměrná roční teplota je 8 – 9 °c (v průběhu vegetace pak 14 – 16 °c). spolu s klimatickými podmínkami má na kvalitu chmele vliv i půda této oblasti. jedná se zejména o permské červenky, ale i o lehčí opukové půdy. na růst a vývoj chmele působí také poloha chmelnic, která je určována zejména nadmořskou výškou (200 – 500 m n.m.), umístěním v reliéfu terénu, jeho svažitostí a expozicí ke světovým stranám. jedná se zejména o široká otevřená údolí s volným prouděním vzduchu, dostatečně chráněná před prudkými západními a severními větry. vzhledem k těmto podmínkám by tento chmel v jiných oblastech nedosahoval takové kvality ani výkonnosti. prostředí ovlivňuje především obsah látek a vzrůst. výše uvedené podmínky (kombinace průměrných srážek, teplot, půdních profilů, nadmořské výšky, světla) jsou jedinečné pro Žateckou chmelařskou oblast. jiné chmelařské oblasti ve světě se budou vždy v některé ze základních podmínek odlišovat (tj. například vyššími srážkami, vyššími průměrnými teplotami, kratší průměrnou délkou dne /denního světla/ve vegetačním období).
