Welcome back to a new year of Earth News Interviews! In this episode, Dean, Winnie, Kathryn, and Tina each discuss their favorite earth sciences paper from 2021. Primary reading discussed: - Using phylogenies to detect a major extinction event in the Oligocene of Africa - Clues from soured milk reveal how gold veins form - Diversity, equity, and in…

We typically expect physical phenomena to follow certain rules: an apple falls from a tree under the influence of gravity, a skater will eventually slow down from the friction between their skates and the ice, a star spins in a similar direction as the planets in its solar system... Here's the interesting bit, the last one doesn't always hold true.…

In this episode, we interview Andrew Parmenter, a geologist working for the Nuclear Waste Management Organization (NWMO), a not-for-profit organization tasked with the safe, long-term storage of Canada’s used nuclear fuel in a manner that protects people and the environment for generations to come. Nuclear waste is a reality our generation has been…

Many Earth Sciences Departments have been recording low enrollment numbers for the last decade. This field has been known to ride the industry wave; high enrollment when the oil, petroleum, and mineral resource industry is booming, low when it's not. This time, the ebb and flow of markets aren't the cause. General public mistrust of the industry, l…

The first exoplanet was discovered in 1992 by Aleksander Wolszczan and Dale Frail. Less than 30 years after this initial discovery that won the Nobel Prize in Physics, more than 4000 exoplanets have been confirmed (NASA). These planets, while unique, have some similarities in mass and size, and potentially other features, to Earth. While we aren't …

With natural disasters become more frequent and damaging, how can we accurately access who's at risk without updated information and predictions? The answer is we can't. That's why accurate risk and hazard mapping is essential for both private homeowners and all levels of government that have a public responsibility to mitigate the adverse after-ef…

Imagine if you lived in a world where some humans evolved the ability to fly, use one hundred percent of their brainpower, or the ability to reproduce at twice the normal rate. These evolved humans would certainly have an evolutionary advantage over the rest of us, and likely outcompete us in the long-term. What if a similar situation happened arou…

For this special New Year's episode, Dean and Sofia trade news stories about new discoveries in the Earth Sciences. The discoveries include the finding of the world's oldest crater, a prehistoric tsunami, and the best way to regrow forests. We finally talk about how we started our podcast, and thank the people who have given us invaluable feedback …

Compared to other foundational scientific breakthroughs like Mendeleev's periodic table, Einstein's relativity, and Watson Crick and Franklin's double helix DNA model, the discovery of plate tectonics is the youngest and one of the most influential in the Earth Sciences. Since the 1960's geoscientists have been building upon John Tuzo Wilson's grou…

What happens when the Canadian government tries to simultaneously decrease fossil fuel demand at the same time as giving subsidies to big oil producers? In this episode, we talk to Professor Miriam Diamond, a contaminant scientist and prolific advocate for climate change action. We discuss the carbon and plastic lock-in problem, and how divergent a…

We're used to thinking of geologic phenomena as events that take millions of years. Think mountain building, subduction, or even the rock and carbon cycles. In this episode, we talk with Assistant Professor Xu Chu about a new discovery in metamorphic petrology: ultra-fast fluid-rock interactions and what they mean for earth system processes through…

In this special episode of Earth News Interviews, we host six guests in a round table discussion about field courses and their place in geoscience programs. Should they be required for a degree? What are some new methods in teaching the material traditionally learned in the field? How can we ensure people aren't excluded from both the opportunities…

In this episode, we discuss original University of Toronto research on Earth's microfibre pollution problem. What are microfibres? Where do they come from? What can we do to help turn the tide? All of this and more with U of T's own PhD. Candidate, Samantha Athey! Primary Readings Discussed: Your Beloved Blue Jeans Are Polluting the Ocean—Big Time…

It's often inconceivable that we can have such a big impact on the environment around us, but nonetheless, humanity has molded the planet to meet its needs. This molding came with its own unintended consequences: Fracking induced seismicity is the crust responding to oil and natural gas exploitation by releasing energy. Even though most of these en…

Removing excess carbon in the atmosphere generated from human industrial activity is one of the most relevant geoengineering feats of this century. But what if we told you the oceans and coastal areas have been doing this naturally for billions of years? In this episode, we sat down with PhD candidate Elizabeth Phillips to talk about speeding up th…

Volcanoes have captured the imagination and intrigue of the human civilization because of their unpredictable and destructive nature. Today, hundreds of volcanoes are being monitored for potential warning signs that precede an eruption including gas emissions, seismic tremors and ground deformation. We sit down with volcanologist Paul Ashwell to as…

In this episode, we discuss both the engineering and socio-political problem that nuclear waste storage has posed since the 1940's. Dealing with tonnes of radioactive waste that needs to be safely stored for hundreds of thousands of years is no easy feat, and as such it has been passed off to every new generation of scientists and engineers. Dr. Do…

In this episode of Earth News Interviews, we discuss the events which added oxygen to our oceans and atmosphere. We get into the importance of oxygen for life, the stability of Earth's systems, and even the search for other planetary life. Primary readings discussed: Breathing new life into the rise of oxygen debate…

In this episode of Earth News Interviews, we discuss scientific journals. What kinds of scientific papers get produced and what kinds of journals accept them? How might review journals be of use to aspiring undergrad and grad students? What is it like to have your work peer reviewed or be the reviewer? Primary readings discussed: Types of journal a…

In the episode of Earth News Interviews, we discuss the current COVID-19 pandemic and the surprising links between pathogens and the earth sciences. How can earth scientists contribute to the study of new outbreaks? Is there a link to climate change? How does land development and deforestation lead to disease? Tune in to learn all of this and more!…

In this episode of Earth News Interviews, we learn about some of the ways gold can get collected in nature via chloride or bi-sulfide complexes. We also talk about the challenges of understanding these processes through modelling, and the extraction of gold in an environmentally and socially conscious way. Primary readings discussed: Resolving the …

In this episode of Earth News Interviews, we discuss the surprising range of health and environmental consequences of small-scale mining operations in Peru. How does mercury affect human health? How does it get from a small mining operation to the bloodstream of people hundreds of kilometres away? Is there anything we can do? Primary readings discu…

In this episode we discuss the field of Economic Geology with Dr. Melissa Anderson. We touch on many timely questions concerning the role of this field in the next century: What have we learned from its history? What are the new frontiers of mining in practice and research? Why is mining so integral in our societies and our transition to a low-carb…

In our inaugural episode of Earth News Interviews, we get into a discussion about the K-Pg extinction event with geophysicist and extinction aficionado, Dr. Charly Bank. We learn about the discovery of a flood layer in North Dakota which may have been deposited in the first hours after impact, and find out what it can tell us about that fateful day…
