Regulating the Earth

"Professing themselves to be wise, they became fools.."

This article from NPR is another example of the elitist outlook and attempt at controlling everything.

As with climate modeling where even a cursory look at the complexities should humble any normal person from believing they could program a realistic outlook of the future based on our limited knowledge of cause and effect in such a vast and unknown physical system-so too is the attempt to regulate CO2.

Reading the article below one quickly grasp that every possible outcome of a regulation can not only not be determined in advance, but may in fact lead to the opposite of the desired outcome.

This constant attempt by the arrogant elitist in science and government to not only understand but somehow predict and control the outcomes of every aspect of human existence and natural processes is not only arrogance, it shows an intellectual blindness that is staggering. They are so wrapped up in their tunnel vision view that they are incapable of common sense. In order to perpetuate their schemes they must constantly create even more complex justifications for their failures leading in turn to ever greater need to control. Like all such endeavors in human history when you build on a foundation of sand inevitably you will end up being buried in it.


Can Dirt Really Save Us From Global Warming?

This month the Senate is set to take up the climate and energy bill that Congress began work on last spring. One provision will likely set up a system to pay farmers for something called "no-till farming."

The concept: When crops are planted without tilling, the soil holds more carbon, which means less goes up into the atmosphere.

But scientists aren't sure no-till really sequesters carbon any better than conventional farming.

Soil scientist Michel Cavigelli of the U.S. Department of Agriculture agrees that no-till fields, like the one he studies in rural Maryland, can hold more carbon than plowed fields.

In part that's because the Maryland field has more organic matter — dead vegetation (mostly the residue from the previous crop), microorganisms, manure or compost.

"The percentage of organic matter in this soil is two percent," Cavigelli says of a no-till field of corn, "twice as much in some of the tilled systems, at the very surface."

But that is only at the surface. Researchers have discovered that when you dig down three feet or so, plowed fields hold just as much — if not more — carbon than no-till.

This is important because the energy bill would allow farmers to earn "offsets" if they practice no-till.

No-Till Offsets: A Fair Trade?

Offsets are like "get out of jail free" cards in Monopoly. If you do something that reduces carbon in the atmosphere, you earn an offset that you can sell to a company that would have to limit its carbon emissions if the bill becomes law. Each offset a company buys allows that company to emit more carbon at its own facilities.

But no-till only stores carbon as long as it isn't tilled. "If you till it, you can lose almost all the carbon you gained in the previous five years say with one tillage, even," says Cavigelli. "So one of the challenges is to maintain your no-till fields forever in essence to really gain the benefits of carbon sequestration."

Rattan Lal, a soil scientist at Ohio State University, says that's not what a lot of American farmers do. "The farmer plows one year and does no-till the next year."

But if it isn't tilled, Lal says, the no-till field can store more carbon than a plowed field if the conditions are just right — the right kind of soil, moisture, and soil temperature, for example.

The Question Of Residue

There's a possible conflict brewing here, though. Federal law and the energy bill encourage farmers to remove crop residue — the remains of the previous season's crop — to make ethanol.

"That's a no-no," Lal says. "The moment you take the crop residue away the benefit of no-till farming on erosion control, water conservation and on carbon sequestration will not be realized."

Nonetheless, Lal supports no-till for carbon offsets, mostly because when you don't plow, you use less fossil fuel to run equipment and make fertilizer.

These savings mean that no-till has a smaller "carbon footprint" than plowing.

Farm interests are eager to win offsets. They say the energy bill will raise their fuel costs across the board. The final list of what will be allowed in the bill could help swing votes when the Senate votes on the measure.
