40 years ago scientists in Antarctica discovered a hole in the Ozone layer. The world acted quickly, phasing out harmful CFCs or chlorofluorocarbons. Evidence suggests the hole has been getting smaller. But in 2025, there are new pollutants threatening to slow progress. Eloise Marais is Professor of Atmospheric Chemistry and Air Quality at University College London and tells Victoria Gill about her work monitoring the impact of space travel on the Ozone layer.It's the first day of the traditional ‘bathing season' when wild swim spots are regularly tested throughout the UK summer. Victoria asks Professor of Environmental Microbiology and Health at Lancaster University, Roger Pickup to break down the science behind our water quality classifications. And May also means wildflowers. Dr Sarah Scott is pollinator ecologist and toxicologist at Cambridge university. She has a warning that planted in the wrong place, wildflowers could be harming bumble bees.Gareth Mitchell, broadcaster and lecturer in science communication at Imperial College London is in the Inside Science studio to bring Victoria new scientific findings which will shape our future.Presenter: Victoria Gill Producers: Clare Salisbury, Dan Welsh, Jonathan Blackwell Editor: Martin Smith Production Co-ordinator: Jana Bennett-Holesworth

40 years ago a hole was discovered in the ozone layer. It provoked an international effort to ban the chemicals that were destroying our protection from the sun. Tom Heap and Helen Czerski are joined by Jonathan Shanklin, one of the team that realised that CFC chemicals used in aerosol cans and refrigerants were helping to create a 20 million square kilometre hole in the ozone layer above Antarctica. Also on the panel they speak to Alice Bell, author of ‘Our Biggest Experiment: a history of the climate crisis' and head of policy, climate and health at Wellcome, and Bristol University's Professor Matt Rigby who helps monitor how well countries are sticking to their promises on protecting the ozone layer.They discuss the unparalleled international unity that swiftly banned the worst of the ozone-destroying chemicals, and ask why we can't come up with a similar solution for manmade climate change. Tom will be delving into the black market in refrigerants and meeting the South American detectives dedicated to hunting down the chemicals that still threaten the ozone layer and come with an enormous cost to the climate.Featuring contributions from:Jonathan Shanklin - Emeritus Fellow, British Antarctic SurveyMatthew Rigby - Professor of Atmospheric Chemistry, University of BristolAlice Bell - Head of Policy: Climate and Health, WellcomeProducer: Beth Sagar-Fenton Assistant Producer: Toby FieldRare Earth is produced in collaboration with the Open University

It has been a cold start to the year and for many that means the heating's on, windows are shut and we're drying clothes inside the house. For many people, mould becomes a major concern in winter and the health problems mould can cause have been under more scrutiny since the death of two-year-old Awaab Ishak who died in 2020 from long-term exposure to mould at his home in Rochdale.At Imperial College London a study called WellHome is underway to monitor levels of mould and other indoor pollutants in homes across the west of the capital. Presenter James Gallagher meets Mum of four Roxanne who had monitoring equipment installed in her house to collect data that could lead to guidance on housing quality and inform how healthcare professionals look for and treat conditions affected by mould. Joining James at Roxanne's is WellHome's Dr Athena Trachalaki, a Respiratory Registrar with Imperial College NHS trust. With her, to go through all the pollutants that pose a risk to our health indoors is WellHome lead and Professor of Community Health and Policy at Imperial College, Frank Kelly. Dr Jonathan Grigg, Professor of Paediatric Respiratory and Environmental Medicine at Queen Mary University, London, tells James it could be the end of the line for the gas cooker, and Professor Alastair Lewis who is Professor of Atmospheric Chemistry at the University of York takes a virtual tour of James's home to discuss all the ways James could be cleaning up the air he breathes.

The biotic pump theory has been controversial in the climate science community ever since Anastassia Makarieva and Victor Gorshkov published their paper about it to the journal Atmospheric Chemistry and Physics in 2010. If true, the theory sheds light on how the interior forests of vast continents influence wind and the water cycles that supply whole nations, flipping traditional hydrological and atmospheric science on its head. Anastassia Makarieva joins this episode to discuss the theory and its implications for future climate modeling with co-host Rachel Donald. Want more?

Smoke from forest fires can produce a spike in ozone levels.

Who doesn't love an eclipse? Apparently, wildlife has very mixed feelings about the whole affair. This month, the guys prepare for the upcoming 2024 total eclipse by looking into the research around how animals react to the moon photobombing the sun for a few minutes. The reactions are not universal, but they are varied. And trying to figure out what the animals are up to makes for a fascinating listen. This episode was recorded on March 20, 2024 at Reinstein Woods Nature Preserve in Cheektowaga, NY.Episode NotesBill mentioned that “wind is air moving between temperature differences.” When listening back to the episode during editing, he worried that maybe he was wrong on that. Looking it up, he did find some websites claiming that wind is due to differences in air pressure and that temperature has little to do with it, but it turns out that's not quite true either. According to the good people at NOAA (The National Oceanic and Atmospheric Administration, the organization referred to in this episode), the answer is both. Their short answer to “what makes wind?” is that it's the movement of gases from high-pressure areas to low-pressure areas. BUT, they go on to say that the main cause of wind is actually temperature. More specifically, it's differences in temperature that lead to different air pressures.It all starts because as the sun warms up the air on the Earth, it does so unevenly. Because the sun hits different parts of the Earth at different angles, and because Earth has oceans, mountains, and other features, some places are warmer than others. Because of this, we get pockets of warm air and cold air.Since gases behave differently at different temperatures, that means you also get pockets with high pressure and pockets with low pressure. Generally speaking (and notice we said generally), in areas of high pressure, the gases in the air are colder and more crowded. In low pressure zones, the gases are warmer and a little more spread out. And this is why wind happens. Gases move from high-pressure areas to low-pressure areas. And the bigger the difference between the pressures, the faster the air will move from the high to the low pressure. That rush of air is the wind we experience.Bill stated that perigee when the moon is farthest from the Earth. WRONG! The point in the moon's orbit where it is farthest from the earth is called apogee, while it's closest approach is known as perigee.Steve mentioned he though an eclipse viewer was like a camera obscura, and he was correct! A camera obscura is a darkened room with a small hole or lens at one side through which an image is projected onto a wall or table opposite the hole. The camera obscura was used to study eclipses without the risk of damaging the eyes by looking directly into the Sun.

Harvard Kennedy School Professor Robert Stavins and Professor Daniel Jacob of Harvard's School of Engineering and Applied Sciences are at the forefront of new efforts to monitor and control methane, a potent greenhouse gas. It used to seem like methane wasn't such a big deal. It was that other climate gas, the one that was the butt of cow flatulence jokes and that only stayed in the atmosphere for a decade or so. But since important global warming targets are now just 7 years away and science has developed a better understanding of both methane's pervasiveness and its potent role in warming the atmosphere, it's now very much on the front burner for increasingly concerned climate policymakers. The good news is that the science of monitoring methane emissions has taken huge leaps forward recently, thanks to advances in supercomputing, weather modeling, and satellite imaging, to the point where we could soon have daily real-time monitoring and measuring of methane emissions around the globe. Our two guests are playing an important role in that effort. Robert Stavins is an economist and the director of the Harvard Environmental Economics Project and the Harvard Project on Climate Agreements. Daniel Jacob was named the world's top environmental scientist last year by Research.com and his groundbreaking work has been instrumental in creating methane monitoring systems so precise they can track emissions to a specific company or another individual source—from space. Both say that the need to address the methane issue is urgent and that the countries of the world now have the wherewithal to get methane emissions under control. There are hopeful signs, including a major international agreement called the Global Methane Pledge, but the big question will be whether global leaders have the will to follow through.Robert Stavins is the A.J. Meyer Professor of Energy & Economic Development, Director of Graduate Studies for the Doctoral Programs in Public Policy and in Political Economy and Government, Cochair of the MPP/MBA and MPA/ID/MBA Joint Degree Programs. He is the Director of the Harvard Environmental Economics Program and the Harvard Project on Climate Agreements. He is a Research Associate at the National Bureau of Economic Research, a University Fellow of Resources for the Future, former Chair of the U.S. Environmental Protection Agency's Environmental Economics Advisory Board, and a member of the editorial councils of scholarly periodicals. His research has examined diverse areas of environmental economics and policy and has appeared in a variety of economics, law, and policy journals, as well as several books. Stavins directed Project 88, a bipartisan effort cochaired by former Senator Timothy Wirth and the late Senator John Heinz to develop innovative approaches to environmental problems. He has been a consultant to government agencies, international organizations, corporations, and advocacy groups. He holds a BA in philosophy from Northwestern University, an MS in agricultural economics from Cornell, and a PhD in economics from Harvard.Daniel Jacob is the Vasco McCoy Family Professor of Atmospheric Chemistry and Environmental Engineering in the School of Engineering & Applied Science at Harvard University. His research covers a wide range of topics in atmospheric chemistry, from air quality to climate change, and has led the development of the GEOS-Chem global 3-D model of atmospheric composition. In 2022, he won both the Best Scientist Award and the Environmental Sciences in United States Leader Award from Research.com as the top environmental scientist in the world. Jacob has also served as a mission scientist on eight NASA aircraft missions around the world and was awarded NASA's Distinguished Public Service Medal in 2003. Jacob has trained over 100 Ph.D. students and postdocs over the course of his career.  In 1994 he was made a Fellow of American Geophysical Union (AGU) and was awarded the James B. Macelwane Medal. He holds a Ph.D. in Environmental Engineering from Caltech. Ralph Ranalli of the HKS Office of Public Affairs and Communications is the host, producer, and editor of HKS PolicyCast.

 Dr. Jessie Creamean is originally from a small town in northern Illinois. She went to college at the University of Illinois, Urbana-Champaign where she majored in Chemistry. She then went on to get her MS and PhD from the University of California, San Diego, where she also studied chemistry, but from an atmospheric/climate perspective. Next, she bounced over to NOAA in Boulder, Colorado where she did my postdoc fellowship on aerosol-cloud-precipitation processes in remote regions. And that, friends, is where she fell in love with the Arctic Region. After working as a Research Scientist at NOAA, she wound up here in Fort Collins as a Research Scientist in the CSU Department of Atmospheric Science. A fun fact about Jessie is that she LOVES the cold. She's been to the Arctic 8 times on land and icebreaking ships, and will be adding Antarctica to her list of places she's worked starting in 2024. Jessie is ALSO an associate editor for 2 major atmospheric journals and has several students and postdocs that work on her projects involving aerosol particles, clouds, sea ice, the ocean, and permafrost. When she is not traveling around the world for work, she loves to enjoy the Colorado lifestyle of climbing, skiing, mountain biking, camping...you name it. She also has two cute, fuzzy golden retrievers, Montana and Whiskey, who are her adventure buddies.  To reach Jessie, email her at jessie.creamean@colostate.edu.

Climate change is here—but it looks nothing like in the movies. Across the planet, the people most affected by natural disasters are somehow still living their lives, experiencing joy while undergoing hardship, thinking up new solutions for our warming world. In Lebanon, an unprecedented economic collapse is wreaking tragedy upon the country, but also bringing around a fervent enthusiasm to innovate, to reinvent, to rebuild our home differently. What does it mean to be human in an age of extreme changes? How do we dance on the boundaries of adaptation? Drawing from experiences out of Lebanon, this talk reflects on how we create hope when the rug has been pulled from under our feet.

Titan Atmospheric Chemistry Revealed by Low-temperature N2-CH4 Plasma Discharge Experiments by Chao He et al. on Sunday 25 September Chemistry in Titan's N2-CH4 atmosphere produces complex organic aerosols. The chemical processes and the resulting organic compounds are still far from understood, although extensive observations, laboratory, and theoretical simulations have greatly improved physical and chemical constraints on Titan's atmosphere. Here, we conduct a series of Titan atmosphere simulation experiments with N2-CH4 gas mixtures and investigate the effect of initial CH4 ratio, pressure, and flow rate on the production rates and composition of the gas and solid products at a Titan relevant temperature (100 K) for the first time. We find that the production rate of the gas and solid products increases with increasing CH4 ratio. The nitrogen-containing species have much higher yield than hydrocarbons in the gas products, and the N-to-C ratio of the solid products appears to be the highest compared to previous plasma simulations with the same CH4 ratio. The greater degree of nitrogen incorporation in the low temperature simulation experiments suggests temperature may play an important role in nitrogen incorporation in Titan's cold atmosphere. We also find that H2 is the dominant gas product and serves as an indicator of the production rate of new organic molecules in the experiment, and that CH2NH may greatly contribute to the incorporation of both carbon and nitrogen into the solid particles. The pressure and flow rate affect the amount of time of the gas mixture exposed to the energy source and therefore impact the N2-CH4 chemistry initiated by the plasma discharge, emphasizing the influence of the energy flux in Titan atmospheric chemistry. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2209.11264v1

In 1985 British scientist Jonathan Shanklin and colleagues published a study that shocked the world. The study revealed a hole in the Earth's atmosphere right over Antarctica. It had been caused over time by chemicals known as CFCs, used in things like fridges, air conditioning units and aerosol cans. These were destroying the layer of ozone in the stratosphere which protects us from most of the sun's ultraviolet radiation - without it, cases of skin cancer would soar. Less than two years after the discovery, world leaders signed an agreement called the Montreal Protocol, committing to phase out CFCs. It has been described as the most successful international treaty of all time - every UN country has signed up, and ozone is expected to return to its previous levels around the middle of the century. So what can we learn from how we tackled the ozone hole in how we address climate change?

If you thought a career in science means spending your best years in a dark laboratory for long, boring hours doing routine experiments, think again! Dr. Cora Young, from York University in Toronto, does a significant part of her environmental chemistry work in the field. From measuring air quality in residential and business spaces, to going high altitude on airplanes, or doing measurements in forests and even in the Arctic. In this episode, we discuss research in the growing field of environmental chemistry, how it differs from traditional analytical chemistry, and what it means bringing high precision analysis out of controlled laboratory environments. Dr. Young sheds light on how analyzing air quality can have a profound impact on international regulations and quality of life. From understanding emissions of worrisome pollutants such as polyfluoroalkyl substances (PFAS), to how cooking at home can affect our health, this is a fascinating discovery of the chemistry of air.

Today’s guest, Ramsey Smith, BS Chemistry, Ph.D in Atmospheric Chemistry. Was a Postdoctoral Fellow at NASA Goddard Space Flight Center (GFSC) where his research spanned the areas of laboratory atmospheric chemistry to ground based remote sensing of planetary atmospheres. Today he is the CEO/Founder of Geaux Innovation Agency - provides strategy, R&D, and commercialization services for science and technology-based entrepreneurs, ecosystem builders and investors.  In today’s episode we discuss how he helped engineers and researchers find opportunities both then and now.

Meet Alex Jarnot, a PhD student at UC Irvine, studying atmospheric chemistry. His lab has quite the pedigree, the original founder shared the Nobel Prize for discovering the cause of the hole in the ozone layer. True to the original cause, he looks at wildfires and agricultural fires and sees how that smoke interacts with urban pollution. In this episode, he also describes some of the surprising peril that comes with this particular line of work. 

Ira Pastor, ideaXme exponential health ambassador, interviews Dr. Penelope “Penny” Boston, recent Director of NASA’s Astrobiology Institute. Astrobiology Astrobiology is an interdisciplinary scientific field concerned with the origins, early evolution, distribution, and future of life in the universe, and considers the big question of whether extraterrestrial life exists, and if it does, how humans can detect it. Astrobiology makes use of molecular biology, biophysics, biochemistry, astronomy, cosmology, exo-planetology, and geology to investigate the possibility of life on other worlds, and how to recognize biospheres that might be different from that on Earth. Dr. Penelope Boston Our guest today, is Dr. Penelope “Penny” Boston, recent Director of NASA’s Astrobiology Institute.  Since May 2016, she led the scientific activities of the institute’s member teams and all operational aspects of the organization whose mission is: to perform, support, and catalyze collaborative interdisciplinary astrobiology research; train the next generation of astrobiologists; provide scientific and technical leadership for astrobiology space mission investigations; and develop new information technology approaches for collaborations among widely distributed investigators. Dr. Boston holds a PhD Microbiology and Atmospheric Chemistry, and her research interests include, but are not limited to, geo-microbiology of caves and mines, space exploration, astrobiology, and extraterrestrial speleogenesis (defined as the study of the origin and development of caves and "karst" – which are specific topographies formed from the dissolution of soluble rocks such as limestone, dolomite, and gypsum). Caves and Karst As a subset of her geo-microbiology focus, she has interest in a topic that we’ve touched on a bit on a previous show in our discussions on tardigrades, namely extremophiles (extremotolerant organisms which thrive in the extremes of altitude, temperature, mineralized environments, pressure, radiation, vacuum, and weightlessness), conditions which may be found in caves and karst on Earth, and which could be looked in for equivalents of other objects in space from asteroids to exoplanets.   As early in Earth’s history, it was a very different planet than it is today, the metabolisms of the various subsurface extremophile microorganisms may give insight into the kinds of microorganisms that lived on the Earth millions of years ago, and which may exist on other planet that still have similar conditions on their surfaces. She was principle investigator on The Caves of Mars Project, an early 2000s program funded by the NASA Institute for Advanced Concepts, to assess the best place to situate the research and habitation modules on a human mission to Mars. Dr. Boston is also associate director of the National Cave and Karst Research Institutein Carlsbad, New Mexico, and founder and director of the Cave and Karst Studies Program at New Mexico Institute of Mining and Technologyin Socorro.  She has also authored/co-authored several publications including "Scientists on Gaia", "Scientists Debate Gaia: The Next Century", and "The Case for Mars." She also writes poetry. On this show we hear from Dr. Boston About her background, how she developed a diverse set of interests, including microbiology, geology, chemistry, physics, and psychology. How she ended up leading astrobiology initiatives at NASA. How close the current cave / karst environments on Earth, that she bio-prospects within, mimic what we can best assume exists on exo-planets. What is involved in her daily research program for discovering novel extremophiles. Interesting properties of the extremophiles she discovers and if they have "earthly use" in industries (Pharma, chemical, etc.). Her opinion of tools such as synthetic biology and directed evolution to potentially reverse-engineer "alien-like" creatures for use in future space missions.

Permafrost Releasing Greenhouse Gases as it Thaws (0:41)Guest: Jordan Wilkerson, PhD Student in Atmospheric Chemistry, HarvardWe've got a feedback loop going on in the Arctic where, as the atmosphere warms, the permanently frozen ground there is thawing. As it thaws, carbon dioxide, methane and nitrous oxide (AKA laughing gas) escape into the atmosphere, where they cause further warming, which thaws more permafrost, which releases more greenhouse gas and round and round. Only now are researchers getting a grasp on how fast that cycle is going. An atmospheric chemistry lab at Harvard just published some data showing there's a lot more nitrous oxide escaping the permafrost than previously thought. Anger Can Actually Be a Good Thing (14:19)Guest: Ryan Martin, Professor of Psychology, University of Wisconsin-Green BayWe often think of anger as a bad thing – it can make us mean and reckless and lead us to believe that the idiot cutting us off in traffic is a monster. And it's even worse on the internet. But anger expert Ryan Martin says we're overlooking the emotion's power for good. Sudden Infant Death Claims the Lives of 3,500 Babies Each Year, But New Research May Be the Answer to Ending It (31:39)Guest: John Kahan, President of the Aaron Matthews SIDS Research Guild at Seattle Children's Hospital, Chief Data Analytics Officer at MicrosoftThousands of infants in the US every year die suddenly, for no apparent medical reason. There's no warning. No way to know if an infant is at risk. The rate of these Sudden Unexpected Infant Deaths has remained steady since the mid-1990s. Efforts to prevent SIDS by putting babies to sleep on their backs and eliminating smoking in the household have reduced, but not eliminated these deaths. Why, with our advanced medical technology and economic wealth, haven't we solved SIDS yet? Breathing and Shaking Toward Recovery from Trauma (50:51)Guest: James S. Gordon, MD, professor of psychiatry and family medicine, Georgetown Medical School, author of “The Transformation: Discovering Wholeness and Healing after Trauma”Overcoming the effects of a serious trauma might include medication and therapy. If you're being treated by psychiatrist James Gordon, it will include deep breathing and frenzied full-body shaking. Dr. Gordon's techniques sound strange, but they've worked for teachers and students affected by the Parkland shooting and for people in Puerto Rico, Houston, Haiti and New Orleans devastated by natural disasters. The techniques have also helped Syrian refugees in Jordan, Palestinian children in Gaza and a range of veterans and victims of war suffering from post-traumatic stress disorder. Jackie Robinson's Daughter on Her Civil Rights Awakening in 1963 (1:28:29)Guest: Sharon Robinson, Author “Child of the Dream: A Memoir of 1963”1963 was a pivotal year for the Civil Rights movement in America. The historic March on Washington happened that summer. In the months before that march, the nation watched in horror as TV news cameras showed Alabama police using firehoses and dogs on African American youth marching in what's known as the Birmingham Children's Crusade. And in September of 1963, four African American girls were murdered in the bombing of Birmingham's 16th Street Baptist Church. 1963 was also a pivotal year in the life of Sharon Robinson, the middle child and only daughter of baseball legend Jackie Robinson.

Wrap your head around this: humans have changed clouds. In this episode of TILclimate (Today I Learned: Climate), MIT professor Dan Cziczo joins host Laur Hesse Fisher to spell out why this is, and what this has to do with climate change. They explore how clouds form in the first place, how human activity has impacted cloud formation and rainfall, and what scientists are still trying to understand. They touch upon the emerging field of geoengineering and how humans could create more clouds to cool the planet — but we’ll have full episode on that coming out soon. Prof. Cziczo is a professor of Atmospheric Chemistry and has been an MIT faculty member since 2011. Prof. Cziczo is interested in the relationship between particulate matter and cloud formation, and his research focuses on how human activities are changing clouds and particles, and what those changes mean for atmospheric science.

Atmospheric chemist Alex Archibald joins me to talk about his pathway into science, taking measurements aboard the FAAM aircraft, and how trees can impact climate.

Feature Guest: Susan Strahan While human activity is what created the ozone hole, scientists just announced direct evidence that human activity is now responsible for healing that damage. That makes the Montreal Protocol, which banned the emission of chlorofluorocarbons or CFCs, along with other ozone depleting substances, the most successful international environmental agreement to date. Today we’re joined at The Star Spot by Dr. Susan Strahan, who lead a team that studied the reduction of CFCs, to discuss the fall and rise of the ozone layer and what this means for future efforts to achieve international cooperation on critical environmental issues like climate change. Current in Space Tabby's star may no longer be the megastructure of another species, but as Tony explains, the way in which we figured that out says quite a lot about this one.  About Our Guest Susan E. Strahan is atmospheric scientist at NASA’s Goddard Space Flight Center where she works in the Atmospheric Chemistry and Dynamics Branch. She holds a PhD in Chemistry from the University of California Berkeley. Her research involves making stratospheric trace gas measurements and studying chemistry-climate models. She is a member of the American Geophysical Union and the American Meteorological Society.  

Dr. James Hansen, formerly of the NASA Space Goddard Institute and current author for open-access journal Atmospheric Chemistry and Physics released a bombshell report about some updated calculations regarding how long we have to bring carbon emissions under control, and the intensity of and speed of which we will experience the repercussions. The main focus of the show is to talk about the intersection of veganism and climate activism. Over the last couple years, there has been a surge in folks calling themselves 'climate vegans', which should be a great thing (and can be) but unfortunately has led to almost as much 'bad blood' between the vegans and climate activists as it has created cooperation and positive change. In the last few shows, Stefan and Daryn made a few throw-away comments about this issue that were understandably misunderstood because we didn't explain why we felt that way, and what our position on veganism and the intersection with climate issues actually is. This is just a brief!
