    Hopi farming: a 2000-year-long agriculture experiment - Radio Cafe
    http://radiocafe.media/downtoearth-hopi/

    Hopi farmers were practicing regenerative agriculture before it was named. Working with the soil, the weather, the water cycle, seeds, and cultural practices, they fed themselves in the dry land of northern Arizona for millennia. Now the industrial food system has challenged their way of living and farming. We talk to traditional Hopi farmer Dr. Michael Kotutwa Johnson; he’s a research associate with the Native American Agriculture Fund and has a doctorate in natural resources management.

    Bill Gates leads $10M investment in Quidnet’s long-duration geomechanical pumped storage – pv magazine USA
    https://pv-magazine-usa.com/...0m-investment-in-quidnets-long-duration-geomechanical-pumped-storage/

    Quidnet looks to use “excess” renewable energy to store pressurized-water under ground at dry oil and gas wells. The startup is aiming to work with electric utilities and deliver commercial-scale projects across the North American electric grid.

    “Quidnet’s GPS technology is a novel form of hydroelectric energy storage. It uses time-tested well-drilling and construction technologies to pump water under pressure into subsurface geological reservoirs to store energy. When variable renewable energy is not available, this water is released to drive hydroelectric turbines to power the electric grid,” said Quidnet CEO Joe Zhou.

    Zhou noted, in an interview with pv magazine that the company was “building off of known supply chains: pumping, wells, drilling, piping, etc.”

    He added, “Today, the duration is ten hours but we can get to tens of hours, maybe hundreds of hours, dependent on the volume of the cavern.”

    The project in New York State will be 2 MW/20 MWh in size, supported through NYSERDA’s High Performing Grid Program. Chou adds, “The 2-MW project will be funded by NYSERDA with $2.5 million — we’ll contribute the other half.” The company suggests that “even at this modular scale, per-kilowatt installed costs are expected to be less than 50% of traditional pumped storage due to simpler civil construction scope.”

    “Integrating renewables and replacing retiring thermal generation require cost-effective long- duration electricity storage at an immense scale,” said the CEO.

    ...

    Companies that have pursued long-duration energy storage include:

    * Flow battery firms such as Primus, Invinity, Sumitomo, UET, ESS and ViZn
    * Gravity-based approaches such as Gravity Power, Ares Power, and Energy Vault
    * Compressed air or gas approaches such as Hydrostor and Highview Power
    * Whatever Form is doing: Form Energy has raised over $50 million in funding from Eni Next, MIT’s The Engine, Breakthrough Energy Ventures, Prelude Ventures, Capricorn Investment Group and Macquarie Capital. Form’s first commercial project is a 1-MW, grid-connected storage system capable of delivering its rated power continuously for 150 hours with Minnesota-based utility Great River Energy.

    Attributing Extreme Events to Climate Change: A New Frontier in a Warming World
    https://www.cell.com/one-earth/fulltext/S2590-3322(20)30247-5

    The emerging field of extreme-event attribution (EEA) seeks to answer the question: “Has climate change influenced the frequency, likelihood, and/or severity of individual extreme events?” Methodological advances over the past 15 years have transformed what was once an unanswerable hypothetical into a tractable scientific question—and for certain types of extreme events, the influence of anthropogenic climate change has emerged beyond a reasonable doubt. Several challenges remain, particularly those stemming from structural limitations in process-based climate models and the temporal and geographic limitations of historical observations. However, the growing use of large climate-model ensembles that capture natural climate variability, fine-scale simulations that better represent underlying physical processes, and the lengthening observational record could obviate some of these concerns in the near future. EEA efforts have important implications for risk perception, public policy, infrastructure design, legal liability, and climate adaptation in a warming world

    After Ice - short film preview
    https://vimeo.com/381247648


    After Ice is a short film that explores how the glacial landscapes of the Hornafjörður region of Southeast Iceland are being affected by climate change. By comparing modern-day drone footage with 3D models created from aerial photography collected by the National Land Survey of Iceland throughout the Twentieth Century, we can gain a glimpse of not only the physical changes but also the aesthetics of a disappearing frozen world.

    Denmark Strikes Historic Climate Deal to Slash Emissions
    https://www.bloomberg.com/...-06-22/danish-parliament-strikes-historic-climate-deal-to-cut-emissions

    Danish lawmakers have struck a climate agreement to ensure their country can live up to a goal of cutting carbon emissions by 70% from 1990 levels over the coming decade.

    The deal, which was entered last night after winning broad backing across party lines, means Denmark will commit to cutting carbon emissions by 3.4 million tonnes. Lawmakers also agreed to build the world’s first energy islands, while investments will be made in carbon capture and greener fuels, the Climate Ministry said in a statement on its website.

    320 Gigatons Drawdown by 2100: A "Win, Win, Win” Strategy
    https://www.facebook.com/groups/Soil4Climate/permalink/2280436375561437

    Eminent soil scientist, Dr. Rattan Lal, Director of the Ohio State University Carbon Management and Sequestration Center, in an exclusive interview with Soil4Climate’s International Policy Liaison, Josie Watson, at the United Nations Food and Agriculture Organization (UN FAO) headquarters in Rome on World Soil Day, December 5, 2018, said restoring degraded soils and vegetation can, by the year 2100, draw down 320 gigatons (billion metric tons) of carbon from the atmosphere — the equivalent of lowering the atmospheric carbon dioxide concentration by 150 to 160 parts per million (ppm). Enumerating many co-benefits of this approach, including addressing the issues of poverty and food security, Lal calls soil restoration a “win, win, win” strategy.

    TRANSCRIPT

    Soil4Climate: How much drawdown of carbon dioxide into soil is possible, in the world?

    Dr. Rattan Lal: That's a very important and relevant question, especially on World Soil Day.

    We have estimated, along with many other colleagues, the possibility is about 150 to 160 gigatons of carbon cumulative until 2100. So, between now and 2100, maybe about 160 gigatons, which is approximately 75 to 80 parts per million (ppm) of CO2 (carbon dioxide) drawdown. Now, this includes all soils, including degraded soils, desertified soils, and so forth.

    But, even if we take the recent estimates of how much carbon has been depleted from the soils of the world, and that means we can replace that much back, that’s about 135 gigatons. So, the estimate of the world soil sink capacity for carbon between now and 2100, for the next 80 years, is somewhere between 130 to 150 gigatons of carbon, which is a very sizable amount.

    If you combine this with also what can be sequestered in the vegetation, that’s another 150 to 160 gigatons. So total, put together, we have a possibility of putting carbon in the terrestrial biosphere, soil and vegetation, about 320 gigatonnes of carbon, which is equal to about 150 to 160 parts per million CO2 drawdown from the atmosphere.

    This is a great opportunity. Not only that, it’s a natural process, it’s also cost-effective, and it has many co-benefits.

    Therefore, it’s very important that we support the activity of the (United Nation’s) Global Soil Partnership (GSP) and other initiatives that have been started throughout the world including (France’s) 4-per-1000 and AAA (Adaptation of African Agriculture).

    I think this is a thing that we should encourage the policymakers meeting right now in Poland to really discuss, support, and undertake.

    We should encourage our policymakers that this process of restoring degraded soils and ecosystems — desertified land — is a “win, win, win” option.

    It’s a bridge to the future. It buys us time until the no-carbon and low-carbon fuel sources take effect.

    At the same time, it is the best option to achieve the sustainable development goals of ending hunger, ending poverty, improving life on the terrestrial ecosystem, empowering women — women are the most important farming community in developing countries.

    So, soil carbon sequestration, terrestrial carbon sequestration, is something we cannot afford to miss. I will strongly support GSP (UN FAO Global Soil Partnership) to follow up with this activity.

    In last year, the congress that was held here at the FAO headquarters was a very successful event, and I hope a similar event can be done in the future.

    The Role of Carbon in the Soil with Rattan Lal
    http://www.youtube.com/watch?v=N7QuG7NmCbc


    John Kempf interviews Dr. Rattan Lal, an acclaimed soil scientist, researcher, and author. In the early 1990s, Dr. Lal was a pioneer of the now-mainstream idea that healthy soils are a defense against rising levels of carbon dioxide in the atmosphere.

    This episode is densely packed with information about soil health and how to achieve it, not only for farmers but also for policymakers and educators. As Dr. Lal says in his closing remarks, "Agriculture, if done properly, has to be a solution to environmental issues.”
