Hello Interactors,I've long been a fan of “regreening” cities, imagining replacing bits of asphalt and concrete with trees, plants, mini-parks, and green roofs to cool them down. In many cases these are indeed good interventions. But even these celebrated nature-based solutions to the “urban heat island” effect require closer inspection. It turns out any land cover change alters energy, water, and momentum exchanges between the Earth's surface and the atmosphere. Which are the right ones and where?To understand why cookie cutter greening plans can fail and how planners and policy makers can build cities that can handle climate change, we need to understand how land and the air interact. Environments vary from place to place, and this puts limits on what we can do to land to create urban climates that are both beautiful and healthy.To get a handle on what the research says, I found a literature review from 2025 that synthesized findings from 84 peer-reviewed studies. In was published in the journal Climate Risk Management.Let's see what they, and others, found.BEATING HEAT WITH BIOPHYSICAL FEATSWhat better place to start than science. Let's just delve right into how urban green spaces affect temperature. It starts with determining the energy balance at the surface of the earth. This comes from a budget equation found in physical geography. When sunlight hits the Earth's surface, it breaks down into three main fluxes, or ways heat moves around* Sensible heat flux: the heat that directly warms the surrounding air, which we measure as temperature.* Latent heat flux: the heat that's used to turn water from a liquid to a gas, like when we sweat or plants release water vapor (transpiration).* Ground heat flux: the heat stored in building materials, asphalt, and soil.In conventional urban environments dominated by concrete and asphalt, latent heat flux is minimal because we've built cities in ways that rapidly drain water away as ‘waste'. As a result, incoming solar energy is funneled into sensible heat. This raises daytime air temperatures that gets stored as ground heat, which is slowly radiated back into the city at night. Urban greening can reshuffle this thermodynamic budget through three interconnected physical mechanisms: shading, evapotranspiration, and albedo modification.Mechanism 1. Shading: Intercepting Solar RadiationShading — the most immediate and reliable cooling mechanism provided by vegetation — requires precise microclimatic quantification. Vegetative canopies act as physical shields, intercepting incoming shortwave solar radiation before it strikes impervious surfaces like concrete or asphalt. By preventing these dense materials from absorbing heat and emitting sensible heat flux back into the boundary layer, shading dramatically lowers surface temperatures and reduces the baseline thermal energy transferred to the surrounding air. (Bowler, D. E., et al. 2010)The cooling benefit of urban trees is non-linear, accelerating significantly once neighborhood canopy cover crosses a critical threshold of around 40%. Measuring daytime air temperatures across urban gradients, they found that canopy cover above this 40% mark can lower local air temperatures by up to 1.5 to 2.0 degrees Celsius, effectively offsetting the thermal burden created by surrounding roads and impervious surfaces. (Ziter, C. D., et al. 2019)Mechanism 2. Evapotranspiration: Trading Sensible Heat for Latent HeatWhile shading blocks heat absorption, evapotranspiration actively removes heat from the air. Plants absorb soil moisture through their root systems and release it as water vapor through tiny microscopic pores in their leaves called stomata. This process requires thermal energy that turns phase-changing liquid water into gas. This energy transfer absorbs sensible heat and converts it into latent heat.Evapotranspiration from well-watered urban green spaces can lower local air temperatures by 2-4 degrees celsius. (Coutts, et al., 2013) However, physical geographers emphasize a crucial physical prerequisite that is easy to overlook: evapotranspiration is entirely dependent on available water. When the soil is dry or the air is super dry, plants close their stomata to save water. When stomata close, evapotranspiration shuts down. This leaves shading as the sole remaining cooling mechanism.Mechanism 3. Albedo Dynamics: The Surface Reflectivity ParadoxAlbedo measures the reflectivity of a surface on a scale from 0.0 (total absorption) to 1.0 (total reflection). Urban asphalt has a low albedo (0.05 to 0.10), absorbing up to 95% of incoming solar energy. Vegetation's albedo can range from 0.11 to 0.25.In temperate climates, replacing low-albedo asphalt with greenery or reflective surfaces increases surface reflectivity, sending more solar radiation back into space before it can be absorbed as sensible heat. One study documented that increasing urban surface albedo typically lowers peak ambient air temperatures by 0.3 degres Celsius to 1.0 degree Celsius — alongside much larger drops in surface pavement temperatures. While a temperature change under one degree Celsius may sound modest at first glance, a baseline shift of this magnitude across a neighborhood is enough to redefine a local microclimate. (Santamouris, 2014)But swapping out light urban surfaces for dark vegetation can also have a negative effect. Paradoxically, when researchers in 2023 replaced dry, light-colored desert soil with darker vegetation in hot, arid regions it reduced overall surface reflectivity. The drop in albedo caused an increase in daytime surface warming. (Schlaerth, et al., 2023)Furthermore, dense tree canopies inside narrow urban street canyons can act as thermal blankets at night. While trees provide valuable shade during the day, their foliage reduces the sky view factor at street level, trapping outgoing longwave thermal radiation emitted by surrounding building facades and asphalt. When combined with reduced wind permeability, this canopy barrier restricts nocturnal radiative cooling and holds warm air near ground level (Lee et al., 2016).These are the physical realities that can demonstrate how urban greening is not a consistently inherent cooling practice. It is a complex thermodynamic intervention whose success relies entirely on local environmental conditions.PLACEMENT, PATCHES, AND PARK PATTERNSBecause thermodynamic processes happen across physical spaces, cooling urban green space can be uneven. The literature review reveals that a green space's cooling capacity depends on four spatial and biological variables: vegetation density, species selection, spatial configuration, and urban morphology. Let's break them down individually.Cooling Factor 1. Vegetation Density and Species TraitsNot all greenery cools equally. One way to measure this is through a Leaf Area Index (LAI). This is the total leaf area per unit of ground area and is a primary predictor of thermal performance. As you might imagine, dense foliage absorbs more from the sun and then produces higher cumulative transpiration (so long as there's adequate water).Botanical traits also play a big role. Broadleaf deciduous species (like oaks or maples) feature large surface areas that maximize summer transpiration, but that goes away when they drop their leaves in winter. Evergreen coniferous trees, however, maintain continuous canopy coverage through every season.In temperate rainforest environments like Seattle or Vancouver, researchers found that conifers cooled urban surroundings up to 1.7 degrees celsius more effectively than broadleaf trees. Dense needle canopies continuously block incoming solar radiation due to higher LAI and the fact that clusters of spiny needles better trap a stable buffer of calm air which moderates heat exchange with the surrounding urban environment. (Eyster & Beckage, 2022, 2023) Cooling factor 2. Spatial Configuration: Landscape Ecology PrinciplesEcologists and geographers commonly evaluate green spaces through two main attributes: composition (how much green space exists) and configuration (how those green patches are arranged across the landscape). Over 58% of the mechanism-focused studies in the literature review analyzed spatial pattern metrics. The consensus is the spatial layout of green space is just as important as its total area!Other empirical studies consistently demonstrate that cooling effects decay the further you get from green spaces. Research done in 2016 and 2023 shows how urban parks can produce a primary “cooling footprint” that extends typically 100 to 300 meters from the park boundaries. If you're lucky enough to live within this buffer, temperatures drop between 1.9 and 3.1 degrees celsius, but beyond 300 meters, the cooling influence quickly falls off. (Bao, et al. 2016, Shi et al. 2023)This spatial limit leads to a couple spatial layout choices. A few big parks or connected networks of smaller green spaces. Large, consolidated parks (>2 hectares) generate intense, stable “cool islands” at their core, but their benefits remain localized. For example, a study in Xalapa, Mexico, revealed that parks larger than 2.8 hectares with over 21% tree cover provided reliable local cooling of around 2 degrees celsius . (Lemoine-Rodriguez et al., 2022)Connected networks of smaller green spaces distributed across a city create a more equitable cooling effect. Three studies in 2019 and 2021 show that fragmented, isolated green patches — like big parks — perform poorly compared to continuous, linear green corridors. Linear “green belts” or street-tree networks (in the right environment) can act as ventilation channels, allowing cool air generated by vegetation to flow into adjacent built-up neighborhoods. (Masoudi et al., 2019, 2021; Pramanik, 2019)Cooling factor 3. Urban Morphology: The Built Environment MatrixObviously, green spaces don't exist in isolation. They're embedded within a three-dimensional hodge podge of buildings, streets, and other bits of infrastructure. Urban morphologists can quantify this urban morphological cacophony using building height-to-street-width ratio and sky view factor - the extent to which surrounding structures and canopies obstruct a location's view of the open sky.High-density urban cores with tall buildings create deep “urban canyons” that generate their own shade. In these settings, building shade can combine with tree shade during peak daylight hours to significantly lower temperatures.However, studies show that if tree canopies in narrow street canyons are too dense — particularly in humid environments — they can trap anthropogenic heat emitted by vehicle exhaust and air conditioning condenser units. They can also significantly reduce localized wind speeds. As a result, maximizing green space cooling efficiency requires aligning vegetation density and canopy architecture with prevailing wind corridors to preserve urban ventilation channels (Cheung & Jim, 2019; Morakinyo et al., 2019).Nothing is every as easy as it seems.BRIDGING GAPS WITH BETTER MAPSWhile academic literature can offer detailed insights into microclimatic processes, there remains a big gap between academia and urban planning and governmental policy. That gap may be self-fulfilling. The literature review of 84 papers revealed 61% of the papers simply advocate for expanding green space area, whereas only 26% focus on optimizing existing green infrastructure.Recommending that dense, historical cities “add more large parks” ignores real-world urban constraints. In modern, rapidly expanding cities, urban land is expensive, highly contested, and structurally constrained. Space dedicated to a new park often competes directly with housing, transit infrastructure, or commercial development. To move beyond idealistic slogans, urban planning will have to recon with three major implementation challenges.Challenge 1. The Water-Energy-Heat Nexus in Arid CitiesThe most significant implementation challenge facing nature-based solutions occurs precisely where urban heat stress is most severe — in hot, arid regions. Cities like Phoenix, Cairo, Tehran, or Riyadh already suffer from intense summer heatwaves. You don't have to live in or visit these places to know water there is extremely scarce.Maintaining green spaces in places like this requires pumping groundwater or desalinating seawater. Pumping and desalinating water requires massive amounts of electricity, which only increases greenhouse gas emissions if that power is coming from fossil fuels. Furthermore, if irrigation water runs out during a heatwave, non-adapted vegetation dries out, loses its cooling capacity, and can even become a wildfire risk.To solve this dilemma, physical geographers advocate evaluating urban greening through a standardized resource efficiency metric: evapotranspirative cooling per unit of water applied. In plain language, this ratio measures how many degrees of cooling you get for each liter (or gallon) of water that plants and soil release into the air through evaporation and transpiration.In dry climates — where municipal water is already tightly rationed and turfgrass is increasingly discouraged but rarely banned (I'm looking at you Arizona) — urban greening strategies are going to have pivot away from high-water lawns and non-native foliage. These cities have to move from simply prioritizing or incentivizing drought-tolerant species to requiring them. While drought-tolerant plants transpire less water than many other plants and trees — and still require water — when combined with drip-irrigation using treated municipal wastewater (greywater), they can provide a pretty reliable canopy shade and even modest evaporative cooling without draining water reserves.Challenge 2. Environmental Justice and Thermal EquityUrban heat exposure is rarely, if ever, distributed evenly across socio-economic groups. In many cities worldwide, low-income neighborhoods exhibit significantly lower tree canopy cover, higher proportions of impervious asphalt, and higher building densities than the more affluent suburbs and ex-urbs. This imbalance leaves more vulnerable populations exposed to extreme heat hazards.When municipalities undertake uncoordinated “regreening” projects, they risk triggering green gentrification. Installing fancy attractive parks can then inflate surrounding property values, displacing residents while still not reducing their heat related vulnerability.To address this, requires targeted interventions like deploying small-scale, distributed interventions (think pocket parks, vegetated bus stops, and road corridors) directly in high-vulnerability, low-canopy/vegetation neighborhoods. You could focus on functional shading over high-maintenance aesthetics. This could better ensure that at least transit stops, pedestrian walkways, and playgrounds are prioritized for canopy cover. Lastly, combining situated green infrastructure with social policy could create and/or protect more affordable housing around old and new greened public corridors and spaces.Challenge 3. A Multi-Benefit, Context-Specific Design FrameworkNo single cooling intervention works everywhere. Planners and policy makers need to adopt an integrated, multi-tiered approach that combines nature-based solutions with material interventions.In arid and semi-arid environments, planners should prioritize structural canopy shading and end an over-reliance on water-intensive lawn evapotranspiration. It's time to demand drought-tolerant trees with greywater irrigation networks, shade sails, and high-albedo “cool pavements” that can better reflect solar radiation without draining water resources.In contrast, humid and more temperate climates would likely benefit most from maximizing green spatial connectivity. By linking existing parks through linear street-tree corridors — with select broadleaf and/or coniferous species — summer evapotranspiration can be enhanced while maintaining year-round microclimate regulation.Finally, within high-density, built-up cores where ground space for new parks is limited, cities should leverage vertical green walls and green roofs paired with reflective building materials. But they best also preserve prevailing wind corridors while preventing nighttime heat traps through street canyons.“Regreening” is a compelling slogan, but as physical geography demonstrates, simplistic blanket policies can yield unpredictable thermodynamic results. Simply planting trees without considering local climate, available water, species traits, spatial configuration, and urban geometry can lead to unintended consequences.The exhaustive synthesis of decade-long research provided by Hadi Soltanifard and Majid Amani-Beni (2025) offers a clear path forward. Nature-based solutions are not off-the-shelf products that can be copy-pasted across different global cities. They are dynamic, living interventions that alter energy fluxes across urban surfaces.By moving beyond blanket acreage targets and framing urban greening as the strategic reorganization of surface-energy relations, geographers, urban planners, and policymakers will need to work together. When we design green infrastructure that respects local environmental constraints, honors spatial equity, and optimizes microclimatic processes, urban greening moves from a vague policy promise toward tools of experimentation that can pragmatically evolve our cities and megaregions into truly climate-resilient urbanscapes.ReferencesBowler, D.

Diciassettemila ettari di suolo nudo dove due anni fa crescevano colture e praterie. A Gaza la terra scoperta è passata da 3.918 a 17.663 ettari, più 351%, e le superfici vegetate sono scese del 65%, da 5.941 a 2.056 ettari. Lo misura uno studio della Libera Università di Bolzano con la Bethlehem University, pubblicato sulla rivista Progress in Physical Geography e ripreso il 9 luglio dall'agenzia Gea. I ricercatori hanno letto le immagini dei satelliti europei Sentinel-2 tra il settembre 2023 e il settembre 2025. Nello stesso periodo, con clima identico, in Israele la vegetazione cala del 4,5% e il suolo esposto sale del 3,4%. Quella forbice misura l'offensiva. Il clima non c'entra. Il dato dice una cosa che i bilanci quotidiani lasciano fuori. I conteggi registrano i morti, almeno 1.084 dall'entrata in vigore della tregua il 10 ottobre 2025 secondo il ministero della Salute di Gaza, oltre 73.000 dall'ottobre 2023. Registrano meno la terra e ciò che la rende abitabile. Il suolo senza radici né acqua è la forma lenta e permanente di quello che la Corte internazionale di giustizia esamina come genocidio. La Commissione d'inchiesta dell'Onu, nel settembre 2025, lo ha ricondotto a quattro dei cinque atti della Convenzione. Il piano di tregua, sulla carta, prevede che Israele non occupi né annetta Gaza. Il 9 luglio, alla Knesset, Boaz Bismuth (Likud), presidente della Commissione Esteri e Difesa, ha rivendicato che «circa il 70% di Gaza è controllato dalle Idf», e ha parlato di una zona cuscinetto permanente. Il territorio che si tiene è lo stesso che si svuota. Su una terra che ha smesso di produrre non si torna, e non si ricostruisce niente. Luigimaria Borruso, che ha firmato lo studio, lo dice nel linguaggio del metodo. «Quando non è possibile accedere a un territorio, il rischio è che anche i danni ambientali rimangano invisibili». Il suolo di Gaza, adesso, è visibile dallo spazio. È tutto il resto a restare fuori campo. #LaSveglia per La NotiziaDiventa un supporter di questo podcast: https://www.spreaker.com/podcast/la-sveglia-di-giulio-cavalli--3269492/support.

A new study has been released that shows the impact of human-induced climate change on global sea levels, focusing on the change from 1900 to 2005.  It found that, worldwide, one in a hundred-year flooding event had a median increase to the 1 in 8-year event average over this time. Even more concerningly, the study found that the increase was not geographically balanced, and Wellington coastal floods have increased to roughly a twice-per-year occurrence. Relevantly, last week Wellington faced large swells up to 9 metres, resulting in a state of emergency and mandatory evacuation orders at numerous bays in the area. To discuss the results of the study and how best to respond to the findings, host Thomas talked to Victoria University Professor of Climate Science & Physical Geography, James Renwick.

In this episode, the team discusses a new paper on why Clovis hunter/gatherers selected certain types of stone for their points and blades. Then the team welcomes archaeologist Scott Ashcraft to discuss his complex federal whistleblower case against the U.S. Forest Service.  Scott Ashcraft attended Western Carolina University, earning a degree in Physical Geography. In the summer of 1989, he was hired for a major archaeological excavation ahead of the construction of a new elementary school within the Eastern Band of Cherokee Indians' Qualla Boundary.   After graduating from WCU in 1990, Ashcraft immediately enrolled in a University of North Carolina-Charlotte field school at a large WNC Mississippian site. Over the next three years, Ashcraft worked on a variety of archaeological contract projects from Mobile, AL, to New York City. During occasional work breaks, he returned to Asheville, NC, to assist Dr. David Moore with large salvage excavations at Mississippian town sites across western North Carolina. In 1993, Ashcraft was hired by the USFS (NFsNC), beginning a 32-year CRM career that eventually broadened to include complementary research and investigative interests.  In 1994, Ashcraft founded the North Carolina Rock Art Project, eventually increasing the state's recorded petroglyph and pictograph sites from seven to more than 120. He also advanced major rock art conservation efforts, including Judaculla Rock—the most densely carved petroglyph in the eastern U.S.—and Paint Rock, among the region's oldest pictograph sites. Another primary career passion for Ashcraft was Wildfire Archaeology, a specialized field he helped pioneer by integrating archaeologists into active wildfire operations to assess and protect important cultural resources. This position required intensive firefighter training and physical conditioning so that archaeologists could play an active role in protecting significant sites during the often chaotic initial attack phase of fire conditions.  As the specialty matured, Ashcraft was invited to co-instruct the National Interagency Fire Archaeology Course over several years. Working closely with Tribal partners—especially the Eastern Band of Cherokee Indians—was among the most meaningful aspects of his later career, including many collaborative projects important to the Cherokee.  Seven Ages Official Site  Seven Ages Official Merchandise  Instagram  Facebook  Patreon  Seven Ages YouTube  News Link Why did Clovis toolmakers choose difficult quartz crystal?   Guest Links Scott Ashcraft  Scott Ashcraft Go Fund Me

This week at least 150 people have been killed due to devastating flash flooding sweeping through areas of Valencia in Spain. Ana Camarasa Belmonte, Professor of Physical Geography at the University of Valencia, has been studying the flood patterns and hydrology of the area for years. Even she was astounded by the magnitude of the inundation. And, as Jess Neumann of Reading University in the UK tells Roland, part of the tragedy is that the effective communication of risk somehow relies on citizens being able to adequately imagine the almost unimaginable.Ten years ago this week, Friederike Otto and colleagues founded the World Weather Attribution network. The network aims to provide quick analysis of climate change's impact on on extreme weather events. They have already found that the Spanish flooding was made more intense, and more likely, by our warming world. Earlier in the week they published a different analysis of the 10 most deadly, extreme-weather events of this century. They concluded that all 10 events were made more extreme or more likely by climate change, and that these 10 events alone account for some 570,000 deaths.In the US, Scientists have tested the strain of H5N1 bird flu swabbed from the eye of an infected Texan farm worker. They found it to be both lethal and transmissible via the respiratory tract of mice and ferrets. It contains a mutation PB2-627K, common in avian viruses in mammalian cells, as Amie Eisfeld of the Universoity of Wisconsin-Madison explains.Presented by Roland Pease Produced by Alex Mansfield Production Coordination by Jana Bennett-Holesworth(Image: Aftermath of catastrophic floods in Spain's Valencia.

In this latest episode of Island Influencers, I delve into Sarah Mercer, co-founder of Earthscope's remarkable story. Originally from Liverpool, Sarah moved to the Isle of Man at age two, shaping her childhood along the island's shores and landscapes. Her academic pursuits in Physical Geography at Durham University sparked a deep interest in environmental issues, leading her to co-found Footprint, an annual environmental summit. Returning to the Isle of Man, Sarah immersed herself in projects like 'Island Utopias', a lockdown documentary capturing community spirit, and 'Manannan's Charms', an app blending folklore with nature. All while living off-grid, making the film entirely using solar power. She collaborated with the Isle of Play to engage children with nature. She explored sustainable practices across Europe with AimHi Earth, presenting alongside notable figures and partnering with impactful organisations globally. Sarah's dedication culminated in co-founding Earthscope, driving carbon literacy initiatives, and advocating for sustainable practices. She is an advocate, nature lover, filmmaker, and sustainability facilitator. Her journey is one of passion, purpose, and a relentless dedication to creating a more sustainable and harmonious world for all. Here is episode 110 with Sharon Sutton in conversation with Island Influencer Sarah Mercer, co-founder of Earthscope.

     Saul was thinking about running an Urban FRPG in the near future and looked to see what kind of materials where available for running an Urban Campaign.   A campaign in that takes place entirely in a city.  He talked to Jolene about it.  She was intrigued by the concept and went off to find what she could on the subject.      Saul remembered a Physical Geography class from Jr. College that discussed where and why cites sprouted in certain areas.  Also how cites are constructed when planned or not, how they are populated and groups that form inside a city.     Saul and Jolene also discuss that most RPG campaign  of different genres usually take place in urban settings.  They discuss the various games they played and play where the primary location is the big city.     Thank you all for listening     Web Art by Jim Foster     Episode Art by Micheal Shean-Jones      The two Waterdeep books that Saul was trying to remember were Dungeon of the Mad Mage and Dragon Heist.          Music by Edna Poli, song Life in a Big City    Available from Tribeofnoise.com     Used under that Creative Commons License 4.0     https://creativecommons.org/licenses/by-sa/4.0/

Just over a week ago, news broke that a tree in the north of England had been felled. The famous Sycamore Gap Tree was approximately 300 years old, and stood beside  a section of the 1900 year old Hadrian's Wall, which the romans began constructing in 122 AD.  But who cut down the famous tree and why?  In this episode of The Quicky, we look into this intriguing crime to find out why this tree was so significant, and what might happen to it now.  Subscribe to Mamamia GET IN TOUCH Feedback?

In March 2023, the UN's Intergovernmental Panel on Climate Change (IPCC) released a synthesis report warning that the world needs to act fast to reduce emissions. The synthesis report is likely to be the go-to document for many stakeholders setting their climate policies and plans over the next several years.    In this episode of ESG Insider, we hear from two authors of the IPCC report: Dr. Aditi Mukherji, who is Director of the Climate Adaptation and Mitigation Impact Area Platform at the Consultative Group for International Agricultural Research (CGIAR). CGIAR is a global research partnership that works with scientists around the world on agricultural innovation and is dedicated to transforming food, land and water systems in a climate crisis.      And we speak to Dr. Peter Thorne, who is Professor in Physical Geography at Maynooth University in Ireland. He is also Director of the Irish Climate Analysis and Research Units group at the university.   "The future we write depends upon the emissions choices we make today and in the coming decades," Peter tells us. He says that the world has the tools to stop global warming, but this will require a concerted effort across all parts of society. "We should get to net zero as quickly as we can. That is the very best, most resilient way that we can move forward," he says.  Photo source: Getty Images  Copyright ©2023 by S&P Global    DISCLAIMER     This piece was published by S&P Global Sustainable1, a part of S&P Global.    By accessing this Podcast, I acknowledge that S&P GLOBAL makes no warranty, guarantee, or representation as to the accuracy or sufficiency of the information featured in this Podcast.

Far from being a modern, internet crackpot idea, hollow earth theory has walked a long and winding path, many centuries old. From the mythological pits of hell, to the pseudo-scientific theories of the enlightenment, right through to modern science fiction, founding philosophies of utopian cults and even tenuous links with the Nazis, the proponents have been many and the theories varied, though whether or not they were ever anything other than crackpot is a different question altogether.   SOURCES   Standish, David (2007) Hollow Earth.

Melvyn Bragg and his guests discuss the history of Antarctica.The most southerly of the continents is the bleakest and coldest place on Earth. Almost entirely covered in ice, Antarctica spends much of the winter in total darkness.Antarctica was first named in the second century AD by the geographer Marinus of Tyre, who was one of many early geographers to speculate about the existence of a huge southern landmass to balance the known lands of northern Europe. But it wasn't until the nineteenth century that modern man laid eyes on the continent.In the intervening two hundred years the continent has been the scene for some of the most famous - and tragic - events of human exploration. In 1959 an international treaty declared Antarctica a scientific reserve, set aside for peaceful use by any nation willing to subscribe to the terms of the agreement.With: Jane FrancisProfessor of Paleoclimatology at the University of LeedsJulian DowdeswellDirector of the Scott Polar Research Institute and Professor of Physical Geography at the University of CambridgeDavid WaltonEmeritus Professor at the British Antarctic Survey and Visiting Professor at the University of Liverpool.Producer: Thomas Morris.

Melvyn Bragg and his guests discuss the Neanderthals.In 1856, quarry workers in Germany found bones in a cave which seemed to belong to a bear or other large mammal. They were later identified as being from a previously unknown species of hominid similar to a human. The specimen was named Homo neanderthalis after the valley in which the bones were found.This was the first identified remains of a Neanderthal, a species which inhabited parts of Europe and Central Asia from around 400,000 years ago. Often depicted as little more advanced than apes, Neanderthals were in fact sophisticated, highly-evolved hunters capable of making tools and even jewellery.Scholarship has established much about how and where the Neanderthals lived - but the reasons for their disappearance from the planet around 28,000 years ago remain unclear.With: Simon Conway MorrisProfessor of Evolutionary Palaeobiology at the University of CambridgeChris Stringer Research Leader in Human Origins at the Natural History Museum and Visiting Professor at Royal Holloway, University of LondonDanielle SchreveReader in Physical Geography at Royal Holloway, University of LondonProducer: Thomas Morris.

Melvyn Bragg and guests discuss how the science of plate tectonics revolutionised our understanding of the planet on which we live. America is getting further away from Europe. This is not a political statement but a geological fact. Just as the Pacific is getting smaller, the Red Sea bigger, the Himalayas are still going up and one day the Horn of Africa will be a large island. This is the theory of plate tectonics, a revolutionary idea in 20th century geology that claimed the continents of Earth were dancing to the music of deep time. A dance of incredible slowness, yet powerful enough to throw up the mountains and pour away the oceans.Plate tectonics, the idea that the earth's surface moved on a carpet of molten magma, constituted a genuine scientific revolution in geology. It explained why mountains appeared and why earth quakes occurred; it explained the curious distribution of fossils across the globe and finally solved the age old conundrum of why continents such as Africa and South America appeared to fit together like a giant jigsaw puzzle. Plate tectonics has made geologists, and many more besides, profoundly re-think what the Earth was, how it worked and how it related to all the things in it.
