Frank Gwazdauskas whose pioneering work on how environmental heat reduces the flow of blood to the female uterine tract where embryos develop allowed me to couple that mechanism directly to climate and to develop a greenhouse physiological killing mechanism. g. This brought him into conflict with the Berkeley team spearheaded by the Nobel Laureate Luis Alvarez that was simultaneously developing the theory that an extraterrestrial impact event had triggered the extinctions. Today after million years of erosion the lavas in black still cover square kilometers and are a mile and a half thick in western India. Many scientists fear that the carbon dioxide build up in the atmosphere will trigger a modern greenhouse climate change

. They burn through the lithosphere plates to erupt as quothotspotquot volcanos. In January at the AAAS National Meeting Toronto Canada I proposed that the Deccan Traps volcanism triggered a major KT carbon cycle perturbation released the KT boundary iridium onto Earths surface and caused the KT mass extinctions. and Rice G. M. Rick Roberts Actor Pontypool. Click here for an enlarged view. He retired from his faculty position in

I have concentrated on the Deccan Traps volcanism involvement in the KT extinctions because such huge and longduration volcanic events release prodigious amounts of the greenhouse gas carbon dioxide onto earths surface. br br Deccan Traps volcanic CO accumulation in marine waters also accounts for the transKT extinction of both swimmers and organisms living on or attached to the ocean floor. In May the impact and volcanogreenhouse theories met and crashed headon at the KTEC II CretaceousTertiary Environmental Change meeting in Ottawa Canada. KT Transition into ChaosToday impactors claim that the Chicxulub structure on Yucatan marks the impact site of the quotKT killer. about percent of the vast Deccan Traps erupted right at KT boundary time million years ago pouring out its vast volume of lavas in to years. On a finer scale it defines the boundary between the Permian geological symbol P and Triassic Tr periods. Known as Piton de la Fournaise it is one of the worlds most active volcanos with more than eruptions in the past years. Introduction. To examine how earths systems are interconnected such that changes in one might affect others see the Holistic Earth Causal Loop Diagram. I quickly realized that finding cause of the KT extinctions must involve searching for unifying methodologies that would allow meaningful integration of the massive data base I had accumulated via study of nearly a couple dozen branches of science. Those were exciting times and my graduate students were in excellent demand and while necessity dictated that I give most of my attention to my dinoflagellate program I expanded my work into paleoecology and paleobiology via research in a couple of dozen fields of science that I deemed critical to developing holistic comprehension of KT dynamics. quot Dick Jahns Dean of the Stanford School of Earth Sciences had recently served on an advisory panel to VPI geology and spoke so highly of it that I accepted the offer. Helen Tappanrsquosnbsp paper ldquoPrimary production isotopes extinctions and the atmosphererdquo that linked atmospheric and oceanic oxygencarbon dioxide ratios to marine algal productivity through time expanded mynbspworld by showing me how to use marine algae to study global climatology and extinctions. It was over four decades ago in the late s that I first began researching the cause of the CretaceousPaleogene transition mass extinction event of million years ago during which the dinosaurs disappeared. I sought the mechanism via using dairy science reproductive physiology to study cause of the PleistoceneHolocene mammalian extinctions during the greenhouse warming at the end of the last ice age years ago


Nbsp Somehow it doesnt seem likely that there will be a rush to abandon the term Petsmart westport rd quotTertiaryquot in popular use. Bowring Syed. Convection in the mantle causes the plates to drift about on earths surface relative to one another. NOTE The Deccan Traps research is but a special theory within the general theory that variations in the carbon cycle exert control upon bioevolution and extinction. experience at Stanford my career ambitions expanded to include study of the role of climate change in bioevolution and extinction. Talk show in which Dr. g. His topics range from bisexual affairs to rape. Mantle plume volcanos release philip kiriakis great volumes of basaltic lavas onto earths surface. Pasco suggested that the original coverage of the Deccan Traps and related lavas was greater than million km. nbspCarl Heneghan clinical reader in evidence based medicine Peter Gill DPhil candidate Braden ONeill DPhil candidate Dan Lasserson clinical lecturerThe Deccan Traps volcanism was one of the greatest episodes of mantle plume volcanism in Earth history and the vast bulk of its lavas erupted right at KT boundary time. quot However the age of the Chicxulub structure older the same or younger petroleum engineering uh than the time of the KT boundary is controversial


This seemed a good place to begin my theoretical research into an ancient world millions years distant about which precious little reliable information existed. In I peyton manning and angela buchman began searching the KT geobiological record for evidences of a KT boundary impact winter. This greenhouse physiological killing mechanism involves environmental heatinduced reduction of blood flow to the uterine tract that damages and kills embryos within their mothers McLean c and later. KT Transition into ChaosToday impactors claim that the Chicxulub structure on Yucatan marks the impact site of the quotKT killer. Other localities showing evidences of KT transition warming are Atlantic Ocean DSDP sites C and Indian Ocean DSDP sites and South Atlantic DSDP site Denmark Biarritz France Lattengebirge Germany Zumaya Spain Caravaca Spain and Pacific and Atlantic Ocean DSDP sites. Mantle degassing continues today as volcanos fumaroles and hot springs release these gases into earths atmosphere. They span the Cretaceous and Tertiary fossil records animal and plant marine and terrestrial biostratigraphy physical stratigraphy plate tectonics carbon cycle stable isotopes mantle processes that include degassing paleobiology paleoecology climatology oceanography biochemistry solarearthspace energy flow systems and petroglyph roseville ca system dynamics to name some


The former was originated by the Berkeley Alvarez team spearheaded by the Nobel Laureate Luis Alvarez. This greenhouse physiological killing mechanism involves environmental heatinduced reduction of blood flow to the uterine tract that damages and kills embryos within their mothers McLean c and later. Other scientists later expanded the impact killing mechanisms to include greenhouse warming and impactinduced global wildfires that burned down most of earths forests for which there is no definitive evidence. The next phase at the KT boundary involved extinction of all the ammonites and the microscopic organisms discussed above. Deccan Traps basaltic lavas ultimately covered a large portion of India under successive horizontal lava flows converting it into an immense volcanic plateau. I hoped to find a teachingresearch position near to the Atlantic Coastal Plain so that I could develop both a palynological program on those strata and also a theoretical research program



Thus did the dinosaurs become extinct. IntroductionAfter Johnny Carsons retirement from the show Jay Leno stepped in as his permanent replacement. Today because of our burning of the fossil fuels coal oil and gas which pff safety rankings is releasing prodigious amounts of carbon dioxide into the atmosphere where it traps heat from the sun that can trigger greenhouse climate change our civilization faces the prospects of a major dangerous climatic warming. In the late s as I was developing the concept of a KT carbon cycle perturbation I searched for a vertebrate physiological mechanism by which to explain the extinction of the dinosaurs as a function philadelphia half marathons of greenhouse climatic warming. That meeting marks the origin of the KT impact versus volcanism extinctions debate. The area shown is about km by km. The fossils I worked on had lived in the oceans just after the extinction event and my research led Petsmart midlothian turnpike me into the extinctions literature. Please see the text of A Climate Change Mammalian Population Collapse Mechanism McLean and the Greenhouse Vertebrate Physiological Killing Mechanism. They are the impact extinction theory which advocates impact of an asteroid or comet with earth and the Deccan Traps mantle plume extinction theory which is based on one of the greatest episodes of flood basalt volcanism in earth history. Harold Morowitzrsquos book Energy Flow in Biology opened my thinking into how energy flow through systems organizes them


So vast was the Deccan Traps volcanism that it would have flooded earths surficial systems with carbon dioxide faster than they could have absorbed it creating fluctuations that would have grown into structurebreaking waves that would have invaded and destabilized them forcing life to change or become extinct. Frank Gwazdauskas whose pioneering work on how environmental heat reduces the flow of blood to the female uterine tract where embryos develop allowed me to couple that petit jean headlight mechanism directly to climate and to develop a greenhouse physiological killing mechanism. Please see her fascinating article titled quotDeccan Traps Eruptions Killed Off Dinosaurs not the Chicxulub Asteroidquot November at httpdinosauroidsp. For the KT terrestrial extinctions including the dinosaurs I proposed climatic heatinduced reproductive failure Petsmart fargo north dakota discussed later in this website and for the marine extinctions a combination of pH change and warming

    Later when the entire earth melted water vapor and carbon dioxide were sweated out of earths interior to the surface. Out of my. Trombley of the Southwest Volcano Research Centre Apache Junction AZ. It is with the greatest interest that I follow the latest research on the Deccan Traps involvement in the KT extinctions by Professor Gerta Keller at Princeton and her associates and especially so because for years she worked to confirm the Alvarez impact extinction theory but was finally won over by evidences opposing it
