The geological record shows that the Earth's carbon cycle suffered over 30 major disruptions during the Phanerozoic. Some of the biggest ones were accompanied by mass extinctions. Dan Rothman analyzed these disruptions to find a pattern governing their magnitude and duration. As he explains in the podcast, this pattern is suggestive of a non-linear dynamical system that, once excited, undergoes a large excursion before returning to where it was. Could we be exciting such a disruption now? He shows that the mass of anthropogenic carbon emissions forecast by the end of the century is about the same as the mass of carbon dioxide outgassed by the massive volcanism that generated the portion of the Deccan Traps deposited just before the end-Cretaceous extinction. This leads him to hypothesize that, while the Chixclub meteor impact may have been the direct cause of the extinction, the disruption of the carbon cycle caused by the outgassing of CO₂ during this prolific series of eruptions contributed to the environmental change associated with mass extinction.

Join Jesse and Chris as we explore the hypothesis that an asteroid ended the Cretaceous AND the age of the reptiles.  It's a very compelling scientific story of discovery.This has been hotly debated back and forth for a long long time, with consensus being reached only recently (since I was in graduate school)Other options include a massive volcanic outpouring - Deccan Traps in India erupted >1 million cubic km of lava in a million year period, with 50% of that coming before the mass extinction event. The question is really about what killed so much stuff?  How does the Earth respond to massive impacts? There have been other large meteorite impacts (and big volcanic eruptions) with no mass extinction - why this one? Was the Earth already in a sorry state (lots of CO2 and mercury in the atmosphere) before the extinction?Flood basalt volcanism is tied to other major mass extinction events (end-Permian and end-Triassic)As we look at the evidence, we bounce around the globe.  We begin in Italy.  1- Gubbio, Italy.  Layers of ancient limestone that are now folded and uplifted.  Working from bottom to top- site became a magnet.  Why?  It has a thin layer of dark clay.  Walter Alverez became v. Interested in this.  He studied the foraminifera below and above.  He found that at the top of the white limestone, the vast diversity of the forams abruptly went missing.  2- Spain - 1500km away.  On the Atlantic coast outside of Zumaia.  2 beaches here which are of interest to geologists because they are situated among the longest set of continuous rock strata in the world.  Jan Smit was studying the forams here.  In these layers, Smit found a strange clay layer - just like Alvarez.  In these rocks, they were steady, consistent, for over a million years, then all of the sudden, the clay layer.  There is no evidence of anything happening and then all of the sudden, the clay layer and bang, they're gone.  How long did this take to change?3- Walter brought in his dad, Louie Alverez.  He brought in his knowledge of Astrophysics.  He found the layer to be rich in IR (also iron, nickel and cobalt).  It contained over 30 X the amount in surrounding rock (measured from the clay at Gubbio).   Could it come from an Asteroid.  He hypothesized that the IR would be spread all over the world as a blanket.  So he could calc. The amount that was laid down all over Earth.  Knowing the amount that is in Asteroids and Comets, they can calc. The size of the Asteroid.  5- Texas on the Brazos River.  65 my this was the bottom of a sea.  We found, Allen Hildebrand, strange sed deposits across the basin.  7 million years of boring mud there.  This was under water.  Then suddenly, we see the mud got eroded.  Suddenly, there were huge boulders in the mud.  Only a giant Tsunami could do this. 6- Haiti: Report of volcanic rocks.  They were actually ejecta full of shocked qtr and spherules.  They were also full of melted rocks called tektites.   7- From Jan Smit: The boundary clay has two parts: lower layer - just 2-3 mm.  It's the most enriched in IR, nickel, FE, and cobalt.  Also has spherules (crystalline and .5 mm).  Remains of micro Tektites.  Also has the shocked quartz.  Highly diagnostic from shock pressures.  9- Shocked minerals are diagnostic of impacts 10- In 2019 in North Dakota, a new discovery - The Tanis (fossil) site.  Evidence of a tsunami deposit.  Has rocks with 3 distinct fish fossils - paddlefish, sturgeon, and ammonites. They pulled gills out of the fish and found a lot of tektites inside the gills - they were swallowing them while still alive.

Some 75% of the world's volcanoes live along the aptly name Ring of Fire. This makes sense. Hugging a boundary between tectonic pates, the Ring of Fire is an open seam on the planet's interior. But then there's Hawaii, a chain of volcanic islands smack in the middle of the Pacific plate, far from any boundaries. What feeds its fire? Scientists have long theorized that columns of superheated rock—piping hot plumes pushing through the mantle to the crust above—explain the Hawaiian islands and other areas like them. Where these columns touch the surface, volcanic hotspots form and the ground erupts. Over millions of years, inch by inch, the Earth's tectonic plates drag new ground over hotspots and form long volcanic chains. The theory is old, but actually observing the mantle plumes feeding these hotspots in any detail is fairly new. “Theoretically, we know [plumes] have to exist,” Harriet Lau, a University of California, Berkeley geophysicist told Quanta Magazine. “But they're just so hard to see seismically.” Now, however, in a particularly striking example, a team of scientists have completed a map of the underworld nearly a decade in the making. The result, beautifully visualized below for a feature in Quanta, is one of the most detailed snapshots yet—and it's surprisingly complicated. Instead of a simple vertical column rising through the mantle, the structure is tree-like, with roots near the core, a trunk mid-mantle, and finer branching structures sprouting near the surface. The plume is feeding one the world's most active volcanoes, Piton de la Fournaise, on the French island of Réunion in the Indian Ocean. But it's also driving an intensely volcanic region in East Africa, some 3,000 kilometers away. Traveling back in time to when dinosaurs still ruled the planet, it ignited an area known as the Deccan Traps. Now in modern-day India, the Deccan Traps spilled enough lava to bury California, Montana, and Texas. Seeing Through the Ground Beneath Our Feet The Hubble Space Telescope is surely a wonder of the world. Imaging galaxies billions of light-years away is impressive—but how exactly does one see through thousands of kilometers of rock? In a sense, geophysicists build ‘telescopes' too. But instead of sensing light, these systems collect and analyze the planet's vibrations. “People have had a longer history and an easier time actually looking up at the stars,” University of Cambridge seismologist Sanne Cottaar told Quanta last year. “Looking down has actually been quite challenging.” To create this particular model of the underworld, the team drew on data from one of the largest such ‘telescopes' to date. In 2012, ships dropped 57 seismometers into the ocean around Réunion. The entire array, which included 37 land-based sensors too, spanned some 2,000 kilometers. Over the next 13 months, the sensors recorded subtle vibrations from seismic activity occurring on the opposite side of the world. As earthquakes rattle the surface, they also ring the planet's insides like a bell. By correlating a seismic event on one side of the world with the shiver it produces on the other, scientists infer what happened in between. Seismic vibrations tend to move more slowly through hotter areas than cooler areas, for example, so a mantle plume would slow their progress. With enough sensors and seismic events, researchers can construct a model. The model, in this case, was surprising. Scientist agree the mantle plumes underlying hotspots are so buoyant and quick-moving they should rise straight up. The diagonally branching paths in the data were unexpected. The team proposes they occur when temperature differences between hotter and cooler material make some areas of the plume more buoyant, pinching off blobs from the top of the trunk (or cusp) over time, one after another. These blobs do rise vertically but appear to form diagonal branches because older blobs have risen higher than younger ones. Nearer the surface, where the upper mantle...

My personal favorite Goodreads list Braiding Sweetgras is on is Ecosocialism & Degrowth. Happy Reading Everyone Today’s Library Tidbit is on Climate Change. Let’s start at the beginning, what is climate change? According to NASA climate change is a long-term change in the average weather patterns that have come to define Earth’s local, regional, and global climates. Global warming is the long-term heating of the Earth caused by human activity since the Industrial Revolution. The burning of fossil fuels has added unprecedented levels of CO2 to the atmosphere which is causing rapid global warming. The Earth has gone through several periods of climate change during it’s history. It is believed, based on geological records, that 2,400 -2,100 million years ago, during the Paleoproterozoic era, that the Earth’s surface froze over in response to the atmosphere and the ocean’s experiencing a rise in oxygen. This is referred to the Huronian glaciation. Fun note here our ocean’s are currently rising in temperature as more CO2 and methane are added to them. The event that is believed to have caused the Huronian glaciation is referred to by a few different things but most often the Great Oxidation Event or GOE. The rise in oxygen in the atmosphere over the next hundred of millions of years caused several different glaciation periods and mass extinction events. The differences between them being uninteresting unless you’re studying prehistoric geology or paleontology. Note paleontologists do not just study dinosaurs but all fossilized animal, plant, bacteria, and virus Around 251 million years ago the Great Dying or the Permian-Triassic extinction event occured. This event saw the most extreme mass extinction ever to occur on Earth to date with the extinction of an estimated 83% of all genera. Genera is the plural of genus which if you remember way back to biology is the rank above species in the taxonomic rank. Reasons for this mass extinction event are unknown but models using the available data say that it would have been caused by ocean acidification. The reason for this acidification is unknown. At about 199 million years ago the Triassic period ends and the Jurassic period begins. The Jurassic period is also the Age of the Dinosaurs. Scientists widely believe that the cause of the mass extinction that ended the Triassic period was increased volcanic activity in the Central Atlantic Magmatic Province. This volcanic activity released large amounts of CO2 in to the atmosphere raising the overall temperature of the Earth and causing ocean acidification. In general times of extreme cooling of the Earth have been caused by raised oxygen levels in the atmosphere and the oceans and times of extreme warming have been caused by raised CO2 levels in the atmosphere and the oceans. At about 66 million years ago the Cretaceous period ended and the Paleogene period began. This also marks the end of the Mesozoic era and the beginning of the Cenozoic era. This is also the event that caused the extinction of all dinosaurs but birds. There are a few theories behind this mass extinction event. One is a meteorite impact at the Chicxulub crater which is large enough to impact the climate of the planet and lead to potential extinction. Two the Deccan Traps in India, a large range of volcanic activity,

For decades, the leading idea has said that the dinosaurs were killed off when a giant asteroid slammed into Earth. But some scientists disagree with that idea. They blame the demise on massive volcanic eruptions. A recent study, though, not only reaffirms the asteroid scenario, but says the volcanoes might have prevented even more extinctions. Most of the dinosaurs died off about 66 million years ago. And they vanished quickly, indicating that something big happened to our planet then. And it did. An asteroid several miles wide slammed into the Gulf of Mexico, off the coast of Yucatan. The impact blasted cubic miles of material into the atmosphere. The debris blotted out the Sun, making the entire planet much colder. The impact also created acid rain and had many other nasty effects. The combination could have changed the climate enough to destroy most of the dinosaurs. On the other hand, massive eruptions were taking place at the same time at the Deccan Traps — massive volcanoes in India. The eruptions lasted for hundreds of thousands of years. They belched huge amounts of carbon dioxide and other gases into the air. The recent study concluded that the effects of the asteroid impact were much more harmful. And the volcanoes actually made things better. Their gases warmed the atmosphere a bit — easing the effects of the asteroid impact by just a little. That may have helped some species survive the long global winter. Script by Damond Benningfield Support McDonald Observatory

Today, we learn about the extinction of the dinosaurs. How did volcanoes, an asteroid, climate change, and tectonic plates cause these once great creatures to disappear from the face of the earth? I also explain how the birds and our mamallian ancestors survive this extinction event, called the Cretaceous-Paleogene extinction (K-Pg for short). The dinosaur extincton happened about 66 million years ago and killed 70% of all species. Enjoy 3D animations and HD videos while listening to the English narration.

The end-Cretaceous (or K-Pg) extinction is one of the best known mass extinctions in Earth's history, primarily because that is when non-avian dinosaurs disappeared. Although the popular idea is that an asteroid impact was what caused the extinction, the science hasn't actually been that clear. More recently, a second hypothesis has challenged the idea asteroid as the main culprit, suggesting that huge volcanic eruptions in what is now India called the Deccan Traps was responsible. It has also been suggested that dinosaurs were already in decline when these things happened, speeding up the inevitable. In this interview, we speak with Dr Alessandro Chiarenza, a research associate at University College London about his new paper published today in PNAS showing that it really was the asteroid impact that killed the dinosaurs. This new study, based on research he did during his PhD at Imperial College London, uses a large amount of data put into climatic models to analyse different scenarios caused by an asteroid impact, the Deccan Traps volcanism, and a combination of the two. This study showed that the asteroid caused a prolonged impact winter, causing the extinction of the dinosaurs.

Er bestaat onder wetenschappers een grote eensgezindheid dat een meteorietinslag 66 miljoen jaar geleden naar alle waarschijnlijkheid* de belangrijkste oorzaak was voor de ondergang van dinosauriërs en het uitsterven van 75 procent van het leven op aarde. Maar vele vragen blijven nog onbeantwoord. Een internationaal team van onderzoekers heeft een nog nooit eerder vertoonde reconstructie gemaakt van de eerste seconden en uren van deze inslag. Dat deden ze door op zee een kernboring van wel een kilometer diep uit te voeren in de resterende krater (in de Golf van Mexico nabij het Yucatan-schiereiland). Uit de stalen die ze analyseerden vonden ze sterke aanwijzingen voor onder andere gigantische tsunami's, explosies van gesteente, vuurzeeën, en grote hoeveelheden zwavel in de atmosfeer. Het onderzoek werd gepubliceerd in het wetenschappelijke tijdschrift PNAS. We praten over de bevindingen met paleontoloog Jan Smit (Vrije Universiteit Amsterdam). Smit is een van de belangrijkste grondleggers van de inslagtheorie voor het uitsterven van de dino's en was ook bij dit onderzoek betrokken. * Over de mate waarin andere factoren meespeelden in het uitsterven van de dino's (zoals de immense vulkaanuitbarstingen van de Deccan Traps voor en na de meteorietinslag), wordt ook nog verder onderzoek naar gedaan.

The gang discusses two papers about the Cretaceous mass extinction event (i.e. the time that the non-avian dinosaurs died). Specifically, they talk about the Deccan Traps, a widespread volcanic province that was active during the extinction event. The first paper studies the timing of the volcanic activity to determine if the onset of volcanism can be explained by the large bollide impact (Editors Note: Apologies to all igneous petrologists who will likely be yelling at our ignorance of hard rock geology). The second paper uses ecological niche modeling to see if dinosaurs were experiencing significant reduction in their geographic range before the extinction event. Also, James is in a “good” mood, so please enjoy as we bounce between topics like Sinclair oil, the French Revolution, “training” children, and experiences at paleo festivals. Its definitely one of those podcasts.   Up-Goer Five (Amanda Edition):  Today our friends talk about the time when the big angry animals with no hair and large teeth all died. One of the ideas is that a very big rock hit and killed everything. Another idea is that rock that acts like water came out of the ground and changed the air and that killed everything by making things too warm or too cold. Many people are starting to think the rock that acts like water that came out of the ground killed the big angry animals with no hair and large teeth, because it seems like they died more slowly that maybe they should have if a big rock hit the ground and killed everything. That would be very fast. But then maybe the big rock that hit the ground really did kill everything, because it turns out that the rock that acts like water that came out of the ground maybe didn't happen at the same time that the big angry animals with no hair and large teeth died. It might also be that big angry animals with no hair and large teeth were maybe around in more places and maybe there were more big angry animals with no hair and large teeth than we think because we only have rocks in some places from some times and that makes it look like the big angry animals with no hair and large teeth died slowly, but maybe they actually died fast.   References:  Sprain, Courtney J., et al.
