Geoengineering, the modification of the climate using technological interventions to reverse climate change, is a hugely divisive issue and we've decided to explore it in two episodes. In this first episode, we talk to scientists working on potential geoengineering technologies who argue the case for conducting research into these interventions. We speak to Shaun Fitzgerald, director of the Centre for Climate Repair at the University of Cambridge in the UK and Hugh Hunt, deputy director at the Centre, as well as Ben Kravitz, assistant professor of Earth and atmospheric sciences at Indiana University in the US. We're also joined by Stacy Morford, environment and climate editor at The Conversation in the US.Part two, out tomorrow, will focus on the case against a particular type of solar geoengineering called solar radiation management. This episode was written and produced by Katie Flood, Mend Mariwany and Gemma Ware, with sound design by Michelle Macklem. Our theme music is by Neeta Sarl.

Live from the Mile High Hunt and Fish Expo with Dan Gates, Charles Whitwam, and John Stallone. We sit down and talk about motivations and the importance of being men of action. Did we take a left turn as a demographic, and where do we have to steer the ship to keep what we love alive? Gather with us for a straight-talking conversation as we navigate the complexities of hunting, conservation, industry and the media. This podcast aims to inspire a different perspective on hunting and urges listeners to contribute constructively to hunting and conservation.
Alentejo the largest wine region of Portugal, is also one of the hottest wine region in the world with many sumer days above 40 degrees and is also one of the at most risk to climate change. The region has long known about this risks and formed an association dedicated to its sustanabily and future proofing called Wines of Alentejo Sustainability Programme (WASP)The nine members of the Wines of Alentejo Sustainability Programme (WASP) that have received their sustainable production certificates have been working on a diverse range of projects to improve the environmental, economic, and social sustainability of their businesses. Those projects extend across both their vineyards and their wineries, and also include work in their local communitiesAlentejo covers approximately a third of the country and is best known for its red wine, the best of which are sold under the and Alentejo DOC (Denominacao de Origem Controlada) title.Wine from Alentejo is typically made from Aragonez (Tempranillo), Castelao, Trincadeira or a rich, ripe, jammy blend of the three. Antao Vaz is the white variety of choice here, producing a good level of acidity and tropical fruit flavors.Nick Breez my guests is a climate Journalist and cofounder of the Cambridge Climate Lecture Series (CCLS)Nick is a climate communicator writing and producing filmed interviews with over 200 experts in the field of climate change. He contributes regularly to The Ecologist and envisionation.co.uk. In 2016 he cofounded the Cambridge Climate Lecture Series with Dr Hugh Hunt and Dr Tony Eva (www.climateseries.com) which, in 2018 was screened in over 15 locations globally, and features speakers at the forefront of action on climate change.Nick is also a wine and blockchain journalist linking both topics to impacts from climate change.Some other useful links on the topic https://secretsommelier.com/alentejo-wine https://sustentabilidade.vinhosdoalentejo.pt/en/wines-of-alentejo-sustainability-programmehttps://www.wine-searcher.com/regions-alentejo Reach us on:Instagram Mattia.lookingintowine Twitter Mattia Scarpazza Mail Info@mattiascarpazza.com
En Afrique du Sud, la fin de l'été austral signe aussi la fin de la récolte de données pour les chercheurs du centre d'études de la foudre. Au sein de l'université du Witwatersrand, une équipe scrute et filme le ciel chaque été, pour tenter de mieux comprendre le phénomène de la foudre. (Rediffusion) Deux tours de communications se distinguent dans le paysage de Johannesburg, et attirent les éclairs du fait de leur taille. Juste à mi-chemin se trouve l'université du Witswatersrand. C'est ici que la chercheuse Carina Schumann a installé ses appareils. « Ici, c'est une caméra à haute vitesse, pour enregistrer 50 000 images par secondes. Et celle-ci, elle se déclenche selon les mouvements, donc on n'a pas forcément besoin d'être là pour la déclencher. Car jusqu'à présent, explique-t-elle, j'ai passé beaucoup de temps à courir sous les tempêtes. » En apprendre toujours plus Grâce à des instruments de mesure installés également sur les tours, la chercheuse brésilienne, avec ses boucles d'oreilles en forme d'éclairs, ne perd pas une miette des différents orages estivaux. C'est durant cette période que les orages s'abattent régulièrement sur la ville de Johannesburg, à la fin de journées chaudes, et où de spectaculaires éclairs peuvent être observés. « La foudre peut tomber jusqu'à 50 fois par an sur ces tours. Pour moi, ces études scientifiques permettent d'aider les ingénieurs à créer de meilleurs équipements de protection, de mieux prédire quand le phénomène va se produire, et d'en apprendre toujours plus. » Car pour ce petit groupe de passionnés mené par Hugh Hunt, à la tête du laboratoire, Johannesburg est un poste d'observation idéal : « Bien sûr, il y a des zones où il y a davantage d'éclairs, souvent plus près de l'Équateur, comme au Congo, au Venezuela, à certains endroits en Indonésie. Mais la plupart de ces zones ne comportent pas de grands centres économiques, remarque Hught Hunt. Ici, notre production d'électricité est concentrée dans la région voisine du Mpumalanga, donc il y a des lignes électriques dans toute la zone. Et notre cœur économique est également situé ici, où il y a beaucoup d'éclairs. » Des dommages très coûteux La foudre tue chaque année plus de 200 personnes dans le pays. Et les dégâts sont aussi économiques, alors que les chercheurs manquent encore d'informations scientifiques sur ce phénomène : « Ces dommages s'élèvent à plusieurs millions de rands chaque année, cela peut aller de la perte de boîtiers internet et de télévision chez des particuliers, à de gros soucis très sérieux sur des lignes électriques, précise le chercheur. Et il y a de nouveaux défis qui émergent avec les énergies renouvelables. Tout d'un coup, tout le monde installe des systèmes solaires, mais il faut étudier comment ils sont touchés par la foudre, c'est différent de nos installations électriques actuelles. Il y a encore des choses à analyser, et de nouvelles situations auxquelles il faut réfléchir. » Les scientifiques ont désormais le reste de l'année pour étudier toutes les données récoltées, afin de déchiffrer les derniers mystères de la foudre. ► À lire aussi : Inondations en Afrique du Sud: le bilan humain ne cesse de s'alourdir
One of the most powerful sources of energy in the natural environment is lightning. These storms are spectacular, but they are also dangerous to people, animals, and the built environment. Dr Hugh Hunt, Senior Lecturer and Head of the Johannesburg Lightning Research Laboratory, Wits University spoke to Radio Islam International; he says that an increase in lightning strikes could be linked to the climate issue and the availability of greater moisture over land as a result of rising temperatures.
A big weight and a very, very deep hole. The team behind Gravitricity think they have found a solution to a serious problem with renewable energy. As we rely increasingly on wind and solar energy the risk rises of the lights going out when the wind doesn't blow and the sun doesn't shine. We can solve the problem with energy storage but batteries are expensive and don't last very long. As Tom Heap and Tamsin Edwards hear, the answer could lie with a deceptively simple pulley system. Put an enormous weight at the bottom of a mineshaft. When you have lots of wind or sun, use the electricity to pull the weight to the surface. When you're short of power, release it and send a huge surge of energy back into the grid.

Special thanks for this episode to Professor Stephen Peake from the Open University and Dr Hugh Hunt from the University of Cambridge.
Last episode, we talked about how we got to where we are now with climate change, but do we even know what's going on with climate change right now? In this episode we'll talk about what tipping points we're approaching, how and why we're still struggling to gain momentum toward action on climate change, and what difference it would make if carbon dioxide was a brown smelly substance.To figure all of this out, we talked to a mathematician, Emily Shuckburgh, an engineer Hugh Hunt and a psychologist, Sander van der Linden. Along the way, we discuss solutions like geoengineering, creating a fake news ‘vaccine' and opportunities for businesses to be more transparent about how their activities contribute to climate change.

His research interests center around the psychology of human judgment, communication, and decision-making, including social norms and networks, attitudes and polarization, reasoning about evidence, and the public understanding of risk and uncertainty. He is especially interested in a) the social influence process and how people gain resistance to persuasion through inoculation and b) how people form (mis)perceptions of the social world, including the emergence of social norms in shaping human cooperation and conflict in real-world collective action problems such as climate change and the spread of fake news and misinformation. His research is regularly featured in the popular media, including outlets such as the New York Times, the BBC, CNN, The Economist, NPR, the Washington Post and Time Magazine.For recent profiles on Dr van der Linden's research see here, here, and
“Surely if you are going to be intervening with some risk in something where the risk is greater if you don't intervene then let's research the intervention!” Welcome to this episode of Shaping The Future - From Pandemic to Climate Change. In this episode, I am speaking with Cambridge University's Dr Hugh Hunt who is also working as part of the Centre For Climate Repair In Cambridge looking at ways to repair the climate. Hugh makes the point that the risks of Geoengineering are less than the impacts from climate tipping points that we are facing if we don't do it. He also gives us an overview of the Centre For Climate Repair set-up by former UK Chief Government scientist, Sir David King, and discusses why funding on a scale to meet the enormity of the climate crisis means unconventional sources maybe be necessary.

Monday 20th Aug 2018Dr Jeyakumar DevarajDr Jeyakumar Devaraj lost his seat in the last election but he is exhilarated that the change of government in Malaysia has permitted a new optimism.Vivien Langford asks him how a new Bandung Spirit would unleash strong climate action. While waiting and waiting for UN green funds maybe ASEAN nations can work together for a new dispensation.He says Malaysia shouldn’t have to cut its health budget to plant trees for carbon sequestration. The funds to help developing countries tackle climate change are insufficient but he says even the developed nations are cash strapped and unable to help while their top 0 .1% of wealthy corporations evade tax. Malaysians are already experiencing intensified floods and heatwaves.They produce only 70% of their food so Dr Devaraj has many solutions to protect the population: from flood mitigation to guaranteeing that land is used to produce food first. He is hopeful that new bold laws will enable restoration of forests, rivers and farmlands. Malaysians have witnessed that the unexpected can happen in government and the lesson we can draw is to prepare for the unexpected. Have the projects and blueprints ready. This fits in with the reasoning behind Beyond Zero Emissions and broadens our awareness to our near neighbour. You can read a talk given by Dr Jeyakumar Devaraj in Kuala Lumpur here.Dr Hugh HuntDr Hugh Hunt was involved in a Cambridge University project called SPICE. (Stratospheric Particle Injection for Climate Engineering) He is a reader in Engineering Dynamics and Vibration and feels that even environmentalists are disconnected from the carbon footprint of our economy . He talked to Vivien Langford at the Climate Adaptation Conference. If we are unwilling to change our own behaviour such as flying, which for every hour in the air emits 100 kilos of CO2, shouldn’t we start talking about cooling the Arctic to buy time? It is a hard conversation to have. He does not want to see climate engineering but thinks we should build up our knowledge of what could go wrong.Dr Hugh Hunt’s research into the effects of climate engineering is ON HOLD because of ethical concerns.Yet where are the ethical concerns which would make us STOP before before flying or filling up a car with petrol?Imagine you had to dispose of 25 white suitcases filled with CO2 after a long hall flight. These videos explain it for adults and children.Imagine you are a world leader. You think it would be electoral suicide to ration fossil fuels and phase them out, so you dream about climate engineering to buy time.What could go wrong ?Are these videos a nudge in the right direction?Radio Team : Andy Britt – Producer, Roger Vize- Podcasts, Vivien Langford – Interviews
