The carbon dioxide in the atmosphere produces a greenhouse effect.

So effectively, for the last million years at least our Earth has had a sheet of glass covering us and keeping things nice and comfortable, and the weather systems STABLE.

Then effectively, over the last 75 years we have double glazed half the planet with all that extra carbon dioxide.

Fortunately for us the oceans are so massive that they are taking their time to heat up. The air blows over them and cools. So things don't feel quite so bad.

But the oceans are slowely and constantly warming.

Everything will continue to heat up if we don't remove the atmosphere's massive CO2 overload.

With the carbon dioxide overload we have already created; no amount of emissions reduction; right up to even total curtailment, can stop this continious heating.

It's already way too late for just emissions reduction to work.


We have added, in total, TW0 TRILLIONS TONNES of CO2 to the atmosphere. The oceans have sucked in one trillions tonnes so they're now overloaded.

So ONE TRILLION TONNES is still there. Give farmers an incentive of $10 a tonne for "soil carbon sequestration" and they can suck out the rest.

Then we go biofuels and nuclear.







And there is absolutely, no "Option B"


Concentrating on "Emission Reductions" is a callous red herring to protect the agrochemical industries. At best it's just slowing the rate we double glaze the other half of the planet.


I've been hammering this approach since I published the first paper on my concept in 1989. (Coincidently; in March, the same year, a CERN scientist dreamed up the concept of the World Wide Web.)


So first; we have to remove the current excess; and second we stop putting more back in.

Removing it can only be achieved by soaking it into our agricultural soils by increasing the humus content of those soils. It's called soil carbon sequestration. It's explained below. Nothing else will work.

Stopping the adding can only be achieved by a complete change to renewable fuels. For power that's mainly nuclear energy and for transport it's got to be biofuels.

The geocarbon fuel industries have to go out of business.
And the agrochemical industries have to go out of business.

It's war!

Or just give up. And if you're over fifty, may be you say "Who cares?".


SOIL So many people ask about it. They say -----

Tell me in a nut shell.

    How does soil carbon sequestration work?

        How do you take the carbon dioxide out of the air
              and put it into the soil?

                                                     I'm Allan Yeomans and this is how I often explain it.:
     Happily it's a completely natural process, but let's keep it simple. To me, the world's grasslands illustrate it best.

1 Cows eat grass.

2 One bite, and the grass plant immediately sheds a few roots.

3 The cows produce waste.

4 Soil microbes and earth worms eat dead grass roots and cow's waste,
       and their waste is humus.

5 Grasses grow best in humus rich soil. So it's full circle, back to the cow.

    That's why the most fertile soils in the world are the grasslands of the world, the steppes, the savannahs, and the prairies. And every one of those grasslands had some type of grazing animal living on it; often for a million years or more. Thus grassland ecosystems automatically create their own humus rich, hugely fertile top soils. It doesn't happen in forests so forest soils always slowly self-destruct.

     Hard rock, near the surface, weathers down and becomes “subsoil”. Subsoil is biologically inert. But when humus is created in that subsoil, then it becomes “topsoil”. It's a billion year old process.

     The chemistry is straight forward. Both living plant materials and soil humus are about half carbon. Carbon dioxide in the air is about one third carbon. Using carbon dioxide from the air, water from the ground, and sunlight from space, the chlorophyll in a blade of grass, or any other green leaf, manufactures living plant materials.

                   Herbivores eat grass, carnivores eat herbivores.

                                And we're omnivores; so we can eat both. "

THE SOIL CARBON SOLUTION ( the only chance we have)

   Stopping global warming and ending climate change right now is feasible and practical. We considerable accelerate soil carbon sequestration to remove from the air the excess carbon dioxide causing the problem. To do it we change to a more chemical free, sustainable agricultural type farming. We use taxation to make it happen. Organic farming, Biodynamics, the Keyline system and similar systems are all extremely productive, extremely effective and cheap. And the way they build soil fertility sucks the excess carbon dioxide out of our air.We start controlling global warming and start terminating climate change. I originated and proposed the concept, (now referred as soil carbon sequestration) in lectures and papers back in the late 1980s. Thankfully it's now at last being seriously considered.
   It's also pritty much essential that simultaneously we switch to ethanol and biodiesel for transport and switch predominately to nuclear energy for power. The oil funded "save the tropical rain forests" and their "nuclear waste is an unsolved problem" is just very clever oil company marketing.


(Added the below today Jan 30 2012. The links noted in the text are fairly standard stuff)

A 2009 study by the California Energy Commission concluded that the use of Keyline plows created the lowest carbon emissions from the subsoil and the addition of compost to grazing lands enhanced the carbon sequestration.  This is an important finding because carbon sequestration, or the capture and removal of carbon dioxide from the atmosphere, is one of the methods to reduce carbon footprints and also a long-term solution to combat the accumulation of greenhouse gasses and global warming.

Regardless of the specific brand of plow used, the concept of the Yeoman's Plow and vertical tillage is a significant aspect of sustainable agriculture Keyline design, and holistic range management
