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.  The CO2 level was at 550 ppm.  This was 55 million years ago.  This very warm period lasted 200,000 years and did NOT  produce an unstoppable warming.  Life flourished subsequent to this period.  Eventually the CO2 level and temperature levels went down and  several million years of hard ice age and glaciation followed.  If the PETM  did not turn us into Venus, nothing we are doing now will.  

Humans do not possess the technology to sterilize this planet.  However  there is little doubt that we could kill ourselves off if we set our minds to it.  But no matter what we do, the Earth will remain an abode of life for the next billion years  barring  an exceedingly large celestial body colliding with Earth and busting the planet into little pieces.

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.

The larger context:

Quote

Paleocene–Eocene Thermal Maximum

From Wikipedia, the free encyclopedia [...]

 

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.

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.^[2]

The associated period of massive carbon injection into the atmosphere has been estimated to have lasted no longer than 20,000 years. The entire warm period lasted for about 200,000 years. Global temperatures increased by 5–8 °C.^[3] The carbon dioxide was likely released in two pulses, the first lasting less than 2,000 years. Such a repeated carbon release is in line with current global warming.^[2] A main difference is that during the Paleocene–Eocene Thermal Maximum, the planet was essentially ice-free.^[4] However, the amount of released carbon, according to a recent study, suggests a modest 0.2 gigatonnes per year (at peaks 0.58 gigatonnes); humans today add about 10 gigatonnes per year.^[5][6]

The onset of the Paleocene–Eocene Thermal Maximum has been linked to an initial 5 °C temperature rise and to extreme changes in Earth's carbon cycle.^[3] The period is marked by a prominent negative excursion in carbon stable isotope (δ¹³C) records from around the globe; more specifically, there was a large decrease in ¹³C/¹²C ratio of marine and terrestrial carbonates and organic carbon.^[3][7][8]

Stratigraphic sections of rock from this period reveal numerous other changes.^[3] Fossil records for many organisms show major turnovers. For example, in the marine realm, a mass extinction of benthic foraminifera, a global expansion of subtropical dinoflagellates, and an appearance of excursion, planktic foraminifera and calcareous nanofossils all occurred during the beginning stages of PETM. On land, modern mammal orders (including primates) suddenly appear in Europe and in North America. Sediment deposition changed significantly at many outcrops and in many drill cores spanning this time interval.

At least since 1997, the Paleocene–Eocene Thermal Maximum has become a focal point of considerable geoscience research because it probably provides the best past analog by which to understand impacts of global climate warming and of massive carbon input to the ocean and atmosphere, including ocean acidification.^[9] Although it is now widely accepted that the PETM represents a "case study" for global warming and massive carbon input to Earth's surface,^[3][10] the cause, details and overall significance of the event remain perplexing.

Yay! Public opinion is very important to you on this issue, isn't it?

Meanwhile, my questions from long, long ago remain unanswered. Remember the "show me the science questions," the "postponed or dog-eaten homework" that you've promised to turn in, but have yet to do so?

Heh. Sea level doom is an "established fact!" Manhattan WILL be underwater in a few years. Lady Liberty will be up to her chin in ocean in a few more. It's a fact. An established fact. And the evil billionaire isn't obeying us! Damn it! We must be allowed to punish him! But until then, the best we can do is find solace in our smug fantasy that his property investments will be underwater soon. That'll show him to disrespect us and our Narrative™!

“It’s funny, that’s the last concern that I have here in Miami, that global-warming issue,” [Jose Isaac Peres] said in an interview Wednesday...

“You’re leaning toward paranoia, you know?” he said, suggesting that Americans are more fixated on the study of climate change than Brazilians are. “You see a ghost, and you run after it as if it were real.” Still, Peres didn’t fully discount global warming, instead saying he didn’t think it was going to occur “as quickly as people imagine.”

...Peres’ climate-change skepticism follows similar statements by a number of high-profile politicians and business leaders, most of them not scientists themselves.

How utterly gauche and uncouth of this Peres thing to not heed his betters.

Let's ask the horse itself, IPCC Special Report, October 2018:

https://report.ipcc.ch/sr15/pdf/sr15_spm_final.pdf

Model-based projections of global mean sea level rise (relative to 1986–2005) suggest an indicative range of 0.26 to 0.77 m by 2100 for 1.5°C of global warming, 0.1 m (0. 04–0.16 m) less than for a global warming of 2°C (medium confidence).

Doesn‘t sound so alarming to me, particularly because it comes from the IPCC.

I think I might have asked if you would read Spencer Weart's book.  Did you give that consideration, or did you look at the website that accompanies and expands upon the book?

Why I recommend it is that it filled in the holes in my general knowledge. Who came first, Fournier, Tyndall or Arrhenius? How can I be reasonably sure that the 'greenhouse' effect is sound and foundational knowledge?

It has meat enough to serve as a general-interest introduction to all the building blocks of what is known to a reasonable degree.

Have we read a book yet?

On 9/16/2016 at 8:47 AM, william.scherk said:

I have cited and quoted Weart's chapter on Simple Models as a primer on where and how the concept of Global Warming formed in the science of the time -- how it came to be, and how it undergirds the rational inquiry that came afterwards.  I recommend to any reader following along: Simple Models (from his book The Discovery of Global Warming, which is available in enriched and updated form at the link).  I recommend the book for its intellectual integrity -- it seeks to explain to a lay reader just how 'the science' of global warming was assembled from the work of many hands, many minds.

Without a historical grounding, I don't think I would be as well-informed as I think I am.

You can become familiar with the 'building blocks' of a present day understanding of the effect of CO2 concentrations in our atmosphere.

The accusatory approach hasn't been working, and has maybe even beenbackfiring. So the leftist climate activists are adopting a new strategy of lessening the focus on blame and hiding their urge to punish, while also upping the scary doom.

The New Language of Climate Change

Scientists and meteorologists on the front lines of the climate wars are testing a new strategy to get through to the skeptics and outright deniers.

https://www.politico.com/magazine/story/2019/01/27/climate-change-politics-224295

 

The "settled science" is that these hick deniers "livelihoods and health will be at stake"? Everything will be worse: "Local crops are dying or washing away at alarming rates"? Oh, fucking no!  More panic! More doom! Urgency, emergency!

Good luck trying to sell those lies to those who live in ag regions, and who grow crops, and who therefore know that you're full of leftist shit.

When the lefty predictions have not succeeded in reality, but yet lefties still want to act as if they have, I guess the only option is to act as if hypothesizing is the final step in science.

It's also interesting that these "scientists" are proposing "solutions" which deal with fields way outside of their areas of expertise, such as the economic risks versus rewards. They know nothing about these subjects, and have not analyzed or weighed any of the consequences of what they are proposing, but rather are just shouting the first thing that pops into their leftist heads: More government! More control! Less freedom for the Others!

Shiftng to a new semantics isn't a scientific mindset. It's still a political ploy, despite the article's claim that they want to avoid appearing to be political.

The scientific approach would be to debate the science with informed critics, rather than avoiding them, shutting them out and vilifying them. Answer their criticisms. Release all of the data and the models/programs. Open up access to everything.

Instead of telling doom stories and making emotional appeals to hunters, fishermen and farmers who don't have access to any of the "science," exhibit the courage of inviting expert critics to present their arguments, rather than maligning and ostracizing them.

But I think we all know that that's not going to happen, because this isn't about climate. It's about power. Actions speak louder than words, and the leftist actions are not consistent with their words, which is why they are focused on semantic tactics.

The key to the warming effect of the greenhouse gases is the stephan-boltzmann  law.  The greenhouse gasses absorb heat and reradiate in all directions. Which means half the heat absorbed radiated downward .  The effect  of the greenhouse gasses is slow the rate at which energy in the infrared frequencies is radiated into space (which is the cold sink for Earth's heat).  According to the stephan boltzmann law the temperature will rise until the outward flux  of energy is equal to inbound flux of energy (from the Sun).  Please see:  https://en.wikipedia.org/wiki/Stefan–Boltzmann_law

Mr Trump gets it.

Pioneering Rush Limbaugh had at it during an earlier excursion of an Arctic winter low:

Limbaugh slams polar vortex 'hoax'

Quote

Do you know what the polar vortex is? Have you ever heard of it? Well, they just created it for this week. Actually, there is a piece. I’ve got a piece in the Stack [Ed: 404 link] that actually makes the case that all of this frigid, chilling cold is due to global warming, strange as it may sound, it says. Other wackos are saying it’s a great example of climate change, but regardless, the agenda is that we’re responsible, we’re causing it, we have to pay the price. And so any weather extreme now is said to be man-made, and therefore it fulfills the leftist agenda on this.

Now, in their attempt, the left, the media, everybody, to come up with a way to make this sound like it’s something new and completely unprecedented, they’ve come up with this phrase called the “polar vortex.” If you’ve been watching television, they’ve created a graphic, all the networks have, and it basically consists of a view of the planet if you are right above the North Pole. They put this big purple blob, or blue blob, or red blob, depending on the network you’re looking at, over the entire North Pole, and they call that the polar vortex. It actually sounds like a crappy science fiction movie to me, but anyway, that’s what they’re calling it. It makes it sound like the jet stream is being forced lower across the United States.

Porn!

Damn it! The cold weather hasn't quite reached record cold. That would've been an extra-exciting propaganda tool. So, I guess we'll have to run with something else. Hardships, frostbite, power-outages, deaths. All due to cold temps due to climate doom. Freezing to death is what your future looks like unless you surrender your freedoms immediately.

With the incursion of quite icy weather into their winter landscapes, I hope all OLers keep safe and sound. Looks like they caught the culprit responsible for the lobe of the vortex ...
