Global Warming Science

The purpose of this site is to encourage activity to reverse global warming, not merely slow it down. Much of the science revolves around greenhouse gas emissions and effects of global warming. This list will focus on the science as it involves the way atmospheric carbon can become terrestrial carbon.

NASA – The Carbon Cycle

  • The carbon cycle diagram on this page is a useful reference for understanding carbon sinks, fluxes, and emissions.

Dr. James Hansen – Target atmospheric CO2: Where should humanity aim?

  • “CO2 will need to be reduced … to at most 350 ppm.”

CO2 Data From Mauna Loa

  • The annual cycle is instructive in that every year nature reduces the CO2 level in the atmosphere, overcoming greenhouse gas emissions.

David Archer — Global Warming: Understanding the Forecast

  • Archer explains it thoroughly, but not academically. Very accessible. U of Chicago also has made available excellent modelling and video resources on this page.

Richard Alley — Earth: The Operators’ Manual, Video

Climate 101 Video

  • Bill Nye explains and demonstrates climate change principles as well as anyone.  While this doesn’t deal with removing greenhouse gasses or reversing the warming trend, it does clarify the connection between greenhouse gasses and climate effects.

Richard Wolfson — Understanding 350

  • In two parts.  More advanced than Climate 101.

The Truth About Global Warming – Science & Distortion – Stephen Schneider

  • Stephen Henry Schneider (February 11, 1945 — July 19, 2010) was Professor of Environmental Biology and Global Change at Stanford University.

The Biology of Global Warming

  • “… it is already too late to mitigate global warming through reducing its CO2 symptoms. We now have no choice but to address global warming through its primary and initial cause. We need to rapidly re-establish natural cloud albedos and their cooling effects. To do this we need to re-establish the bio-systems that provided the transpiration and cloud nucleation processes on which such cloud albedos and cooling effects naturally depend.”

Planetary Boundaries

  • “Here, we present a novel concept, planetary boundaries, for estimating a safe operating space for humanity with respect to the functioning of the Earth System.” Climate Change is ranked third, out of the nine identified boundaries, in magnitude of exceeding earth’s boundaries behind behind Biodiversity Loss and Excess Nitrogen Use

A Tenth Boundary

  • Steven Running — “…there should be a tenth boundary: the amount of available biomass.”

“There is no distinction between us and the natural world. There is just the thin membrane of life and life processes clinging to the Earth’s surface which we call the biosphere and of which humans are merely a part.”

Feeding The World

It is not so much a question of feeding the world or survival as of our relationship with nature and each other.  We can feed as many as we need to, but not the way that agriculture is doing it now.

Joel Salatin – Can We Feed The World?

Brown Revolution Brings New Hope

Sepp Holzer – Desert or Paradise

  • Not that we should encourage more population growth, but Holzer claims that 21 billion people can be fed using large-scale water harvesting restoration methods. This book illustrates stunning reversals of landscapes, and the techniques he employs. Permaculture over hundreds of acres at a time!

Pasture Cropping — Colin Seis

  • Sowing crops in pasture, minimal erosion, less yield than top producers, but earning more income due to much lower costs, while alternating with grazing.

John D. Liu — Green Gold: How can we regenerate large-scale damaged ecosystems?

  • Liu  documents remarkably successful mammoth scale restoration projects in China, Africa, South America and the Middle East.  ”The solution to fix the major problems of the worlds ecosystems remains reasonably simple. We have to go ahead on a major scale now.” — Geoff Lawton

Forestry, Agroforestry

How much forest is there, and how much have we lost?

Eric Toensmeier on Carbon Sequestration in Agroforestry

  • “Terraforming the planet into a perennial food-producing paradise may be the only way to avert climate disaster.”

Copenhagen – Analysis of Forestry Carbon

Community Carbon Trees

  • Tropical Forestry can rapidly and massively sequester carbon, and needs to be properly designed and managed.
    “If we are truly to create lasting solutions to the environmental problems facing the planet, we have to do MORE than plant trees for global warming. . . . Ideally, we also have to find ways to preserve local communities and cultures, while immediately rebuilding deforested soils, wildlife corridors and protecting watersheds and old growth forests. This work is especially important in countries like Costa Rica where there still exist intact stretches of primary jungle along the coast which, in turn, influence the oceans and marine life, together so vital to the overall stability of our global climate”.
    Jennifer Smith, Founder and President of Community Carbon Trees in Costa Rica

Abundncia — Ernst Gotsch

  • Documentary shot in an Agroforestry workshop by Cooperativa Sitio, in Viseu, Portugal, about all the knowledge and philosophy that’s behind it and the interest of so many people in this way of sustainable agriculture. Agroforestry (or food forestry) is a production method that proposes, not the creation of a new production environment, but that man, and the agricultural production from which takes advantage, are included in a forest environment. The method is, in its essence, an attempt to imitate nature. In nature most plants live in association with other species, witch they need for a complete and healthy growth.  In the 70′s, Ernst Gotsch worked with the genetic optimization of plant species. This research lead him to the conclusion that instead of trying to adapt the species, he could get better results if he created agro-ecosystems in witch plants, in a cooperative system, would develop vigorously without chemical inputs. He Implemented numerous complex and highly productive systems that avoided all kinds of fertilizers and pesticides. Since 1993, after achieving outstanding results, he has dedicated himself to teach his methods all over the world.

Soil Carbon

Dr. Christine Jones

  • Scroll to bottom for links to articles.
  • “The deeper in the soil profile that carbon is sequestered, and the more humified the carbon, the better.”

John Kempf on Carbon Induction

  • “A healthy plant will have at least as much root biomass below ground as there is plant biomass above ground. So if we have 100 pounds of plant biomass above ground, and an additional 100 pounds below ground, this still represents only 30 to 40 percent of this plant’s total energy production. This [carbon induction] is the real secret to building soil carbon effectively and efficiently. We can readily see why forage-based livestock agriculture and perennial polycultures are the most efficient method of building soil organic matter and stable humic substances. Carbon induction is the answer.”

Climate Change and Desertification — The Problem is the Solution

  • “Soil carbon sequestration is an important and immediate sink for removing atmospheric carbon dioxide and mitigating global warming and climate change. Organically managed soils can convert carbon dioxide from a greenhouse gas into a food-producing asset. Combined with sequestration in non-agricultural soil, the potential for land to hold carbon and act as a sink for greenhouse gases is unparalleled.”

Replacing Grass With Trees May Release Carbon

Grasslands/Holistic Management

Joel Salatin – Tall Grass Mob Stocking

Greg Judy

  • You don’t need to live on a farm, or own one, to start farming. Read his Comeback Farms, and No Risk Ranching: Custom Grazing on Leased Land. The Judy’s raise cattle, sheep, horses, goats, pigs, and chickens on fresh, fully rested pasture in rotation, high density, without chemicals. Another great book by another great Missouri rancher is Cody Holmes’ book, Ranching Full Time on Three Hours a Day. Livestock management doesn’t need to be costly or time consuming if done holistically.

Cody Holmes — Ranching Full-Time on Three Hours a Day

Holmes does tall-grass, multi-species, mob grazing on 1000 acres in Missouri.  His point is that ranching doesn’t have to be burdensome if the farm is well designed, and nature does the work.
