Say, what caused this ancient climate change, because apparently warming is totes different?
Ancient climate change triggered warming that lasted thousands of years
A rapid rise in temperature on ancient Earth triggered a climate response that may have prolonged the warming for many thousands of years, according to scientists.
Wait, what? Go ahead and read that again. Are you seeing what I’m seeing? A rapid rise in temps caused prolonged warming? Huh what? It actually sorta makes some sense in full context, however, it’s still stupid
Their study, published online in Nature Geoscience, provides new evidence of a climate feedback that could explain the long duration of the Paleocene-Eocene Thermal Maximum (PETM), which is considered the best analogue for modern climate change.
The findings also suggest that climate change today could have long-lasting impacts on global temperature even if humans are able to curb greenhouse gas emissions.
“We found evidence for a feedback that occurs with rapid warming that can release even more carbon dioxide into the atmosphere,” said Shelby Lyons, a doctoral student in geosciences at Penn State. “This feedback may have extended the PETM climate event for tens or hundreds of thousands of years. We hypothesize this is also something that could occur in the future.” (snip)
“One lesson we can learn from this research is that carbon is not stored very well on land when the climate gets wet and hot,” Freeman said. “Today, we’re pushing the system out of equilibrium and it’s not going to snap back, even when we start reducing carbon dioxide emissions.”
So, what caused that all to happen? Were the cave lions, woolly mammoths, and cave bears driving fossil fueled vehicles and powering their casas with coal?
William Teach: A rapid rise in temps caused prolonged warming?
It’s called feedback, like feedback with an electric guitar.
William Teach: So, what caused that all to happen?
It’s believed that the initiator of the event was a spike in atmospheric carbon, causing an increase in the greenhouse effect. There are a number of natural sources of atmospheric carbon, such as volcanism or disturbance of a kimberlite field. At that point, a positive feedback may have occurred, such as the warm oceans eroding fossil carbon adding more to the greenhouse effect.
WTF?

They are simply reporting on something that is already known. When the climate warms dramatically the ice melts. When the ice melts it opens up vast and I do mean vast amounts of tundra which has sequestered massive amounts of co2. When this co2 is put into the atmosphere at alarming rates then the feedback they are discussing takes place.
This is just a rehash of an already existing theory. However the key here is Paleocene-Eocene Thermal Maximum (PETM) Time frame.
The Paleocene–Eocene Thermal Maximum (PETM), alternatively “Eocene thermal maximum 1” (ETM1), and formerly known as the “Initial Eocene” or “Late Paleocene Thermal Maximum”, was a time period with more than 8 °C warmer global average temperature than today.[citation needed] This climate event began at the time boundary of the Paleogene, between the Paleocene and Eocene geological epochs.[1] The exact age and duration of the event is uncertain but it is estimated to have occurred around 55.5 million years ago.
Climate change during the last 65 million years as expressed by the oxygen isotope composition of benthic foraminifera. The Paleocene-Eocene Thermal Maximum (PETM) is characterized by a brief but prominent negative excursion, attributed to rapid warming. Note that the excursion is understated in this graph due to the smoothing of data.
For context. This epoch began 65 million years ago and begs the question of why the rapid warming. What triggered the rapid warming. It is estimated during this time frame that there were over 4400 ppm of co2 in the atmosphere as well as substantial amounts of methane. Now however because this led to a lush tropical rain forest the resulting water vapor in the air was considerably larger than today.
This is nothing new. What is new here is the attempt to inject a feedback loop into the equation as to why this happened. So 99 percent of the people who read this will go batshit crazy and begin screaming were all going to die when the reality is earth thrived and flourished during this time frame. The only draw back is that the dinosaurs ruled the earth. This will simply push indigenous species north and south were this to happen today meaning the shore lines would alter drastically.
Additionally a paper was published which has subsequently been removed from the internet because it was so damning. That paper stated briefly that even during this time frame the Greenland Ice sheet only shed 40 percent of its ice in this 20,000 year time frame when the co2 was 4400 ppm and that additionally with a 12 degree rise in earths average temperature even that over 20k years could not melt all the ice on this planet.
The AGW crowd was aghast and the paper was not up very long before removed, purged from the annals of human history to cover up their narrative that in a 100 years were all going to drown to bleed money from the civilized western cultures.
Why does anyone think this type of NAZISM exists in the AGW science community? It is because of the Globalist new world order led by the communist George Soros who wants a world wide fascist government and this is his hit man to make it happen. Terrorizing the young with the fear were all going to die if we dont give our lives to George Soros’s new world fascist order.
Pathetic and being exposed
To Illustrate my point above. WERE ALL GONNA DIE…you know all you young kids should rise up and demand the world pay for what exactly? Universal health care which is 30 trillion and the Green NEW DEAL which is 10 trillion.
IF>>>IF>>>IF>>>>IF were all gonna die. Shouldn’t we be spending 40 trillion on the Green NEW DEAL instead of worrying about universal health care.
The stupidity of the left and the SHEEPLE who follow them is insane. THIS^^^ right here is why Nancy Pelosi is unable to make a deal with Trump. 1/3rd of her party is insane lunatics like AOC and the rest of the neo-liberals are falling into lockstep out of fear of being primaried out of their cush government job.
The left continually blames the right for fear mongering and yet the democrats have the patent on fear mongering. The right is not blameless but the left has now officially lost their collective minds after trump was elected.
