Michael Kudish is a Catskills legend and the authority on Catskills trees and forests. In 1971, Kudish earned his PhD with the thesis, "Vegetational History of the Catskill High Peaks." Five decades later, that research is ongoing. In 2000, Purple Mountain Press published his landmark book, The Catskill Forest: A History. Now, an updated 6-volume set is in the works. I met up with Michael at his home/research library in Delaware County, to hear about his latest research sampling Catskills bogs and radio carbon dating peat and charcoal for even more insights into our Catskills forest past.  --- Thanks to this week's sponsors: Briars & Brambles Books, Hanford Mills Museum, and The Mountain Eagle.

LOOP 8.2: Prof. Danielle Schreve, Royal Holloway University of London, joins us to cover the last 2 million years of Earth's history. We explore the periodicity of glacials and interglacials and the control Earth's orbit around the sun has on climate. She then places the Holocene's megafaunal extinctions and major palaeobiogeograpical events within this climatic context. We finally look at the impact of human radiation on the world and the lessons we can learn from this time. Life On Our Planet (LOOP) is a new 8-part series created for Netflix by Silverback Films and Amblin Television. This Steven Spielberg produced series, narrated by Morgan Freeman, is hugely ambitious in its scope, telling the story of life throughout the whole Phanerozoic Eon. Ancient organisms and environments are painstakingly recreated by the supremely talented Industrial Light and Magic, whilst modern natural history scenes add vital context to the story. This show has been worked on for six years, during which time countless papers were read and around 150 different palaeontologists contributed their time and knowledge. The whole production had culture of letting the scientific rese arch dictate scenes, resulting in one of the most accurate on-screen representations of prehistoric life there has ever been. And how do we know all this? Well, our very own team members Tom Fletcher and Dave Marshall have been embedded within the LOOP team since day one! We are therefore in a totally unique position to reveal to you the work that went into this series, from both the production and research side of things. In this unofficial series, we've been granted exclusive access to many of the people responsible for creating LOOP, we explore what it takes to create a palaeontological documentary and we delve deeper into the science with some of the show's academic advisors. Each day, we will be releasing batches of interviews, each relating to a specific episode of LOOP. Image courtesy and copyright of Netflix.

La thèse la plus communément admise sur le peuplement évoquait une traversée à pieda par le détroit de Béring, immergé à la faveur de la dernière glaciation. Des preuves archéologiques, comme des pointes de lance qui servaient à tuer les mammouths, ont longtemps suggéré que le peuplement était vieux de 13 500 ans. Mais depuis plus d'une vingtaine d'années, la thèse est remise en cause par de nombreuses découvertes archéologiques. En puis finalement en 2021, une découverte déterminante a tout changé, ça s'est passé au Nouveau-Mexique.

Nick wonders if the Ice Sheet ever reached Spokane, Washington.

Episode 47 We dare you to say ‘Ice Aged Ice Sheets' five times fast. But first, in this episode, the GotR Gang dive into all things Glaciers, brrrr. Glaciers and Glaciation, generally speaking, covers the formation, features, effects, and causes of glaciation events on Earth. Ice sheets and alpine glaciers are described, including their movement and erosional features and landforms. Glacial deposits will be examined, including a discussion of the features created by till and stratified drift. Other effects are worthy of discussion, including crustal subsidence and rebound, sea level changes, alterations to streams and stream valleys, and the formation of proglacial and pluvial lakes. However, there is not enough time in one episode to bring you all the fun facts about glaciers. Remember, if you fall down a crevasse, the good news is you will only fall 50 meters. The bad news is that you will fall 50 meters. Between the bars of our main discussion, we present to you another Mineral Minute, then close things out with special guest Joe Guzman of Space Poets to promote his Psychedelic Panther Music Fest during this week's That Freaking Rocks!

Garry Nolan is a gemologist and sunblind. He talks about how he became interested in gemology and how he became blind. He also discusses freightliner and exponentials.

Terre boule de glace, volcanisme hyperactif ou période du Sahara Vert : au cours des derniers milliards d'années, et jusqu'il y a quelques millénaires, la Terre a connu des climats très différents de ceux d'aujourd'hui, des périodes essentielles à comprendre pour anticiper les changements climatiques. D'où cette question : quels furent les climats de notre planète ? Pour y répondre nous recevons Gilles Ramstein, paléoclimatologue, directeur de recherches au Commissariat à l'énergie atomique et aux énergies alternatives (CEA) et auteur de Voyage à travers les climats de la Terre.  Interview réalisée par Maxime Thuillez Suivre le Greenletter Club :

The Soom Shale is an Ordovician lagerstätte in the Western Cape of South Africa. Whilst it lacks the diversity of organisms seen in other lagerstätten, such as the Burgess Shale or Chengjiang, it more than makes up for it in the fidelity of preservation. The taphonomic pathway to the fantastic preservation in the Soom Shale is long and complex, reliant not only on local conditions, but also ties into global climatic events. It’s vitally important when interpreting fossils to understand the taphonomy as it provides so much context as to what you can see in fossils and, as equally important, what you can’t. Joining us for this episode is Prof. Sarah Gabbott, a taphonomist from the University of Leicester, UK.

#017 – Piecing Together Yukon's Rocky History – An Interview with Head Yukon Surficial Geologist, Jeff Bond.  In today's interview with Jeff Bond, we discuss the adventures, challenges, and changes in the field of Surficial Geology and how recent scientific analysis techniques have aided Yukon's mineral exploration industry. Jeff's lifelong learning mindset and commitment to the field of geomorphology has served him well. From his curious beginnings as a youth interested in basic rock exploration in the Okotoks area of Alberta, to the wildlands of Canada's northernmost territory, he's been able to take his interest in geomorphology and cleave it into a fulfilling career of adventure and exploration.  As the head Surficial Geologist for the Yukon Geological Survey, Jeff has had the opportunity to explore regions of the territory that most people will rarely be able to access. No stranger to the outdoors and the risk/rewards that go with it, Jeff has taken it upon himself to formulate many a plan that would get him into the most remote areas of the Yukon.  By accessing areas by water, hiking and air travel, he's collected years of data in vast portions of the territory that are sometimes accompanied with the occasional ice water capsize, helicopter rescue, and random wildlife encounter.  To listen to the full podcast show, please click on MyAmazingYukonLife.com where you'll find each weekly podcast link along with show notes and pictures related to each of the episodes.

YTG Placer Gold Geologist Jeff Bond gives you not only the accurate directions to the starting point of this amazing hike, but some in depth background into the geological history that shaped the Ibex and Takhini River basin. Classified as an "intermediate/advanced" hike, the Ibex Ridge provides some incredible vistas as you ascend 6909 ft to its summit. Essentials for this hike requires a camera for those photo ops, good hiking boots, warm clothing, food and water are essentials for your day out.For the full podcast show please click on MyAmazingYukonLife.com where you'll find each weekly podcast link along with show notes and pictures related to each of the episodes.

In this episode, we interview Dr Leigh Anne Riedman, University of California, about life during the Neoproterozoic Era, the most recent of the Precambrian Eon. This time interval is far from straight forward; not only were there changes in oceanic and atmospheric chemistry,  but also dramatic shifts in climate and the formation and subsequent rifting of the supercontinent Rodinia. The Neoproterozoic also saw major biological innovations and ended with the appearance of the enigmatic Ediacaran Fauna. Leigh Anne studies acritarchs, relatively simple, single-celled walled microorganisms and by examining their diversity and abundance, she is able to comment on how life fared during this turbulent time.
