Trump and his ignorant climate-denier base have put the gun to humanity's head and are about to pull the trigger.

 

 

Rapid global warming caused the largest extinction event in the Earth’s history, which wiped out the vast majority of marine and terrestrial animals on the planet, scientists have found.

Save millions of lives by tackling climate change, says WHO

The mass extinction, known as the “great dying”, occurred around 252m years ago and marked the end of the Permian geologic period. The study of sediments and fossilized creatures show the event was the single greatest calamity ever to befall life on Earth, eclipsing even the extinction of the dinosaurs 65m years ago.

Up to 96% of all marine species perished while more than two-thirds of terrestrial species disappeared. The cataclysm was so severe it wiped out most of the planet’s trees, insects, plants, lizards and even microbes.

 

Scientists have theorized causes for the extinction, such as a giant asteroid impact. But US researchers now say they have pinpointed the demise of marine life to a spike in Earth’s temperatures, warning that present-day global warming will also have severe ramifications for life on the planet.

 

“It was a huge event. In the last half a billion years of life on the planet, it was the worst extinction,” said Curtis Deutsch, an oceanography expert who co-authored the research, published on Thursday, with his University of Washington colleague Justin Penn along with Stanford University scientists Jonathan Payne and Erik Sperling.

The researchers used paleoceanographic records and built a model to analyse changes in animal metabolism, ocean and climate conditions. When they used the model to mimic conditions at the end of the Permian period, they found it matched the extinction records.

 

According to the study, this suggests that marine animals essentially suffocated as warming waters lacked the oxygen required for survival. “For the first time, we know with confidence that this is what happened,” said Deutsch. “It’s a very strong argument that rising temperatures and oxygen depletion were to blame.”

The great dying event saw Earth’s temperatures increase by around 10C (18F). Oceans lost around 80% of their oxygen, with parts of the seafloor becoming completely oxygen-free. Scientists believe this warming was caused by a huge spike in greenhouse gas emissions, potentially caused by volcanic activity.

The new research, published in Science, found that the drop in oxygen levels was particularly deadly for marine animals living closer to the poles. Experiments that varied oxygen and temperature levels for modern marine species, including shellfish, corals and sharks, helped “bridge the gap” to what the model found, Payne said.

 

“The past holds the key to the future,” she added. “Our current rates of carbon dioxide emissions is instantaneous geologically speaking and we are already seeing warming ocean temperatures and lower oxygen in many regions, currently affecting marine ecosystems.

“If we continue in the trajectory we are on with current emission rates, this study highlights the potential that we may see similar rates of extinction in marine species as in the end of the Permian.

Gee, an asteroid crushes open the mantle and the magma comes pouring out for a period of time that may have lasted between a lunar cycle, seasonal shift, revolution around the star would elevation of temperature  in this atmosphere long enough to cook the food chain present adapting to how the food chain developed and survived without asteroids hitting the surface that hard.

 

Now no asteroid has struct the surface since and the natural cycles returned to constant changes within the same cycles. But human intellect invented ways to doubt perpetual balancing sustaining the species within the moment here.

Am I reading this right?

 

A massive meteor crashed in to the planet and totally blocked the sun out and everything froze.

 

Have they changed that?

OK this is BS and they know it,  the temperature rises first then the gas rises after temperature, the position of the sun = warming or cooling, people are not creating global warming, the corporations need to clean up their own pollution with your subsidies and you will be needing your money for some heavy coats and extra fire wood preparations in case an emp knocks out your utility's along with the ATM machine etc.

Oh God you people are so gullible. 🤣

 

Not actually.  The warming was caused by arthropod CO2 emissions.  The warming caused it.  It was the methane clathrates which ruptured and caused a sublimation of oxygen on the planet due to the massive "great burp" of methane emissions.

 

Warming is dangerous.  The question STILL remains whether or not it is caused by humans.

 

I"ve told you all a million times, watch Parker.  It will tell us the radiation budgets in accurate terms.

 

Most of you are too ignorant to know about this - the "great burp" has been known to us for quite some time.

 

Methane clathrates are sequestered in the deep ocean and the tundras.

 

We know that they are breaking up.  If the tundras go - we go.

Also, scientists are not stupid, because it's hard getting a higher tier science degree.  It hurts when you get it. 

 

But some scientists are corrupt.  Most are not. 

 

I think maybe you need the ban hammer. I don't trust you.  I don't think you are a conservative. I think you're a Russian web brigade guy.  That's what I think.  I don't think any conservative says "trump is smarter and will tell you what to do."

 

I think you're a troll.  A wretched troll.  You should be ashamed of yourself, son.

That was a different extinction event. An asteroid disrupted the environment and was responsible for the death of the dinosaurs. Iridium layers, impact on paleobotany, and the rise of the mammals are in evidence at that time period. The article cited in the OP refers to an earlier mass extinction.

There are cycles, but the crisis now happening is because of manmade carbon dumping into the atmosphere.
