    GeoEngineering and the Garrett Relation

    Dr. Richard Nolthenius has a background in thermal engineering and astronomy. He currently runs the Astronomy Program at Cabrillo College, Santa Cruz California. He also lecturers and has been a visiting researcher for UC Santa Cruz since 1987. He describes his professional transition in to climate science as "quite a shock, not necessarily a pleasant one"! Dr. Nolthenius suggests that Professor Tim Garrett's work on linking global wealth and energy consumption has not been given the attention it deserves, Dr. Nolthenius also concludes that the only way to advert the increasingly critical climate change situation is in line with Prof. Garretts publications and therefore requires sharp, rapid cuts to our use of fossil fuels. To achieve this end Dr. Nolthenius has compiled a list of 7 Policy Mechanisms which he will discuss in Part one. These include: Tax and Dividend End government subsidies to fossil fuel companies Trade sanctions against all countries who do not enact Tax and Dividend or end fossil fuel subsidies. Devise an efficient mechanism to impose Tax/Dividend on all externalized costs. Tax consumption, not income. End Child Tax Credit, and promote policies which economically discourage population growth. Amend the Constitution. Dr. Nolthenius explains exactly what the above may involve, and discusses ideas for getting them implemented with a million person Occupy DC movement. In Part Two Dr. Nolthenius highlights potential technological 'band aids' (and their short falls) which could potentially be implemented alongside the Policy Mechanisms discussed in Part 1. These include: Energy technologies (PV, Wind, Hydroelectric, Geothermal and Nuclear). Carbon Capture and storage Artificial capture of CO2 from the atmosphere via 'Air Capture' Climeworks commercially operated Air Capture CO2 machine. BECCS – BioEnergy with Carbon Capture and Sequestration. Dr. Nolthenius also points out how even if we ended all our carbon emissions today, the effect of Thermal Inertia would still cause global temperatures to rise. Part 3 covers GeoEngineering including: Permafrost Carbon How do we choose? Solar Radiation Management 'Butterflies' Asteroids with dust secretion Reflective Aerosols Refreezing the Artic using pumped sea water. 'Loan Shark' methods that won't work long term Why there is no 'Magic Bullet' Reference is made by Dr Noltheius to "E.C.S", although not covered in the series this stands for Equilibrium Climate Sensitivity. More information on this is available in Dr Noltheniuss presentation 'Earth Climate Change in One (very long) Lecture' available here: https://www.dr-ricknolthenius.com/Apowers/ClimateInOne19a.pdf  Many thanks to Dr Richard Nolthenius for joining me for this 3-part series, I hope I can discuss more issues with him in the future. I highly recommend visiting his website where there is a wealth of information available: https://www.dr-ricknolthenius.com/  . His Collage lecture presentations (powerpoint and pdf versions) relevant to the topics covered can be found at: https://www.dr-ricknolthenius.com/astro7/A7PowerIndex.html . Professor Tim Garretts work as discussed can be found here: http://www.inscc.utah.edu/~tgarrett/Economics/Economics.html All 3 parts where recorded Friday 27th October 2017. ---------- Join in the discussion on my website: https://www.slipperychimp.co.uk/2018/01/01/geoengineering-and-the-garrett-relation/

  5. What's the link between wealth, energy demand, CO2 and Climate Change?

    06.10.2017

    What's the link between wealth, energy demand, CO2 and Climate Change?

    Tim Garrett is Professor of Atmospheric Sciences at the University of Utah who's research focus is the physics of clouds. Professor Garrett joins Steven to discuss his work, and model, which shows a consistent link between the global economy and climate change. Professor Garrett's model indicates the constant requirement of 9.7 Watts to support every $1000 (adjusted to the 1990 Dollar) means it is impossible to decarbonise the economy and prevent catastrophic climate change within six decades. Steven and Tim discuss why Jevon's Paradox supports this position and means that as we constantly strive for energy efficiency, ironically, the more energy we use. To find out more on Professor Garrett's work please visit http://www.inscc.utah.edu/~tgarrett/Economics/Economics.html For an additional explanation provided by Dr Richard Nolthenius please view his presentation here: https://www.cabrillo.edu/~rnolthenius/Apowers/A7-K43-Garrett.pptx ---------- Join the discussion on my website: https://www.slipperychimp.co.uk/2017/10/06/linking-wealth-energy-demand-co2-and-climate-change/

  6. The Voluntary Human Extinction Movement (VHEMT)

    04.09.2017

    The Voluntary Human Extinction Movement (VHEMT)

    The Voluntary Human Extinction Movement (VHEMT) is a 'radical' environmental movement who believe that the voluntary choice to not create more humans is the only viable method to save the planet from environmental catastrophe. In this Episode of the Environmental Professionals Postulating Podcast, Steven is joined by Les Knight, the founder / discoverer of VHEMT. The main object of the movement, based on environmental arguments, is the voluntary choice to not create new humans. To find out more about VHEMT visit their website at http://www.vhemt.org/  ---------- Join the discussion on my website: https://www.slipperychimp.co.uk/2017/09/04/the-voluntary-human-extinction-movement-vhemt/
