Global warming friends...Trump is dead serious and will wipe out probably far more then just Obama's

Abrupt chemical weathering increase across the Permian–Triassic boundary

• Nathan D. Sheldon,

Abstract
Previous studies have suggested a variety of causes for the end-Permian extinction event including a bolide impact, flood basalt volcanism, methane clathrate dissociation, or some combination of catastrophic processes. One common feature of these hypotheses is the prediction of an enhanced earliest Triassic greenhouse. New high-resolution geochemical results from Graphite Peak, Antarctica support an abrupt increase in chemical weathering in the earliest Triassic among otherwise genetically similar paleosols of similar provenance. Relative to the latest Permian paleosols, the earliest Triassic paleosol exhibits greater leaching, greater accumulation of immobile REEs, and evidence of lower soil pO2. With no evidence of an erosional unconformity between the paleosols, which are separated by < 15 cm stratigraphically, these results support a rapid shift (perhaps < 10,000 years) to an earliest Triassic greenhouse and a role for methane release in the extinction event and its aftermath.

Abstract
High-resolution oxygen isotope records document the timing and magnitude of global warming across the Permian-Triassic (P-Tr) boundary. Oxygen isotope ratios measured on phosphate-bound oxygen in conodont apatite from the Meishan and Shangsi sections (South China) decrease by 2‰ in the latest Permian, translating into low-latitude surface water warming of 8 °C. The oxygen isotope shift coincides with the negative shift in carbon isotope ratios of carbonates, suggesting that the addition of isotopically light carbon to the ocean-atmosphere system by Siberian Traps volcanism and related processes resulted in higher greenhouse gas levels and global warming. The major temperature rise started immediately before the main extinction phase, with maximum and harmful temperatures documented in the latest Permian (Meishan: bed 27). The coincidence of climate warming and the main pulse of extinction suggest that global warming was one of the causes of the collapse of the marine and terrestrial ecosystems. In addition, very warm climate conditions in the Early Triassic may have played a major role in the delayed recovery in the aftermath of the Permian-Triassic crisis.

Climate warming in the latest Permian and the Permian–Triassic mass extinction

My goodness, multiple lines of evidence from different sources. Yes, there was a very warm period after the initial pulse of the Siberian Trapps, and that was the primary driver in the extinctions of 95% of the Earth's species. Try to catch up, old man.

Abstract
Global warming is widely regarded to have played a contributing role in numerous past biotic crises. Here, we show that the end-Permian mass extinction coincided with a rapid temperature rise to exceptionally high values in the Early Triassic that were inimical to life in equatorial latitudes and suppressed ecosystem recovery. This was manifested in the loss of calcareous algae, the near-absence of fish in equatorial Tethys, and the dominance of small taxa of invertebrates during the thermal maxima. High temperatures drove most Early Triassic plants and animals out of equatorial terrestrial ecosystems and probably were a major cause of the end-Smithian crisis.

Lethally Hot Temperatures During the Early Triassic Greenhouse | Science

Really Mr. Westwall, a massive volcanic event, yes. Cold for a while, yes. But that has happened before, and not resulted in a 95% species die off. However, plenty of proof for the hothouse conditions that came immediately after the short cold period, and persisted for a long time, even geologically speaking.

Cold for a "while". Get real silly boy. The evidence for continental glaciation is everywhere from that time. There is zero evidence for your hot house. Which, even if it had happened would have been a mere return to the normal state of things considering that over 75% of the Earths history has had warmer temperatures than now. We are ABNORMALLY LOW TEMP.

My, my, I just posted research by real scientists, not message board frauds, that says otherwise. And, yes, there was Permian glaciation, and the critters did just fine during those glaciations. Only with the eruption of the Siberian Trapps, and ensuing Greenhouse conditions did the Great Dying take place. And, yes, there is ample evidence for that.

Oh goody. Care to point to anything in those "studies" that is like factual.... I'll wait.

Why don't you point out what you think is not?

How did this thread become about Permian weathering?

Trumps election means one thing and one thing only. NOBODY gives a rats ass about Permian weathering, glaciers or anything else about the hoax!! duh.........

The eye poke(s) on this is going to be particularly brutal for the progressives who embrace climate k00kism.And wait'll the courts go to what they should always be..........then you meatheads are fucked for at least a generation, maybe two.
