Asterix





This is a delightful article written by an old idealist who did go back to the land and resurrected productivity on a scruffy piece of abandoned land.  Like many both in the sixties and before him, he became the champion of this patch of land and worked with it to make it perform.  He saw what it was as wild country and brought it back to full fertility.

I personally think that every child needs to participate in that experience and to some degree throughout theirs lives. 

I think a true farmer understands this.  Our intervention alters the ecology to optimize production of human food stuffs.  Those who have followed my posts know that it has become possible to do much more.  Principally the advent of the biochar protocol will be the most revolutionary advance in human husbandry since we learned to turn soil and throw in seeds.

The biochar is not itself a nutrient but it holds available nutrients in place. It is quickly discovered that artificial fertilizers soon become redundant as plant waste and other wastes are returned to the soils.  The biochar prevents escape.

The power of the individual is that he can perfect his husbandry of a patch of soil somewhere.  I want you to think about that though.  When you stand in a field, you are standing on the shoulders of many generations of men and women who cared for that particular field.  Often little was needed but when called upon they responded.  They found ways to make it fertile and well enough drained to produce a crop.

Our human task is to care for every field and to restore to hands on human management huge tracts of good land that will respond to our attention.

I particularly welcome reports of this nature.

I also think introducing Asterix is a great idea to remind us what it means to be a yeoman farmer.  Curiously, I grew up on a nineteenth century farm and am quite comfortable with that life way.  In fact, I do know what to do if I were dumped in the midst of a forest with and axe, a whetstone, and few other supplies with a handful of other Scottish pioneers to lend a hand.  At least this chap had a rototiller. 


Small is beautiful (and radical) 

3 FEB 2010 9:41 AM


When a friend told me of two of the proposed discussion topics for a major agricultural conference—“What is so radical about radical agriculture?” and “Is small the only beautiful?”—I told him that that I thought both questions had the same answer.  Let me see if I can explain. 


The radical idea behind by organic agriculture is a change in focus.  The new focus is on the quality of the crops grown and their suitability for human nutrition.  That is a change from the more common focus on growing as much quantity as possible and using whatever chemical techniques contribute to increasing that quantity.


None of the non-chemical techniques associated with organic farming are radical or new.  Compost, crop rotations, green manures and so forth are age-old agricultural practices.  What is radical is the belief that these time-proven “natural” techniques produce food that is more nourishing for people and livestock than food grown with chemicals.  What is radical is successfully pursuing that “unscientific” belief against the counter-propaganda and huge commercial power of the agrochemical industry.


The initiators of this new focus were a few perceptive old farmers from the 1930s and ‘40s who had not been taken in by commercial pressures and saw clearly the flaws of chemical agriculture.  The popularizers of the new focus were the young idealists of the 1960s and 70s who were attracted to the idea of food production based on non-industrial systems, even though most of them had no previous connection to agriculture.


The effect of those new young minds entering agriculture defined the early days of organic farming in the US and thus also provides a context for the second question—“Is small the only beautiful?”  Small became beautiful because of the passion of the new generation of idealistic young farmers.  I was like most of them.  I had no farming background, no farmland, and very little money.  None of us would have been able to buy 500 acres in the Imperial Valley even if we had wanted to. So we ended up on a few acres of inexpensive, abandoned land because of economic reality rather than by conscious choice, and we started farming with compost and rototillers.  The flavorful produce we sold, plus our passionate belief in quality, established the connection between the words “small” and “beautiful” in the public mind.


Once our combined efforts succeeded in making “organic” popular, the real farmers, the large-scale professional farmers, became interested.  (We always knew we weren’t considered “real” farmers.)  For most of them, growing organically was a market decision as opposed to the deep passion for soil quality and food quality that had inspired us hippies.  Since the age old farming techniques had not been abandoned because they couldn’t work but because chemicals were promising miracles that they couldn’t deliver, the transition to organic farming was not difficult for the large farmers and they began selling “organic” produce.  But the “small is more beautiful” idea remains in the public mind, because the organic-buying public intuits that the large-scale farmers may have changed their agronomy but not their thinking; that their minds are still logically focused on how much they can produce rather than on how well it will nourish their customers.  I don’t think the public objects to scale (America is the land of large farms) but rather objects to organics by the numbers.  They don’t see the old-time hippie passion for quality produce or any innovative new soil fertility improvement ideas coming from the large farms.  They just see coloring between the lines according to the minimum standards that USDA certification requires.


From the point of view of this old hippie who carved his farm out of spruce and fir forest on the rocky Maine coast and had to learn everything about farming as he went along, I envy people who are able to farm on large expanses of flat naturally fertile soil and who have generations of farming experience behind them.  Because of the poor quality of the land on which I started 40 years ago it took the first ten years of removing rocks, and stumps, and creating fertility to give us the marvelous soil and ability to grow exceptional food that we have achieved and continue to maintain.  
I often think of how much further all that effort could have gone had I grown up on a “real” farm but then I realize that if I had, it would have required an equal effort to change from the “quantity first” focus that has so characterized American agriculture to the new “quality first” focus established by the organic pioneers.

 
So if we go back to the two questions about what is “radical” and what is “beautiful” they come down to the same thing—the passion for quality food and sustainable systems that the new young farmers brought to American agriculture.  There is no reason that large farms, whatever path they may have been on, cannot learn to meet those standards if they understand that it is not the scale of the farm but the attitude of the farmer that the public is interested in.  I think if the large farmers used all their experience and natural advantages to try to lead food production along ever more nutritious and sustainable lines, they would have the respect that so many of them obviously feel they deserve.


But there is one other connection between the word “radical” and small farms that I need to mention.  The small organic farm greatly discomforts the corporate/industrial mind because the small organic farm is one of the most relentlessly subversive forces on the planet.  Over centuries both the communist and the capitalist systems have tried to destroy small farms because small farmers are a threat to the consolidation of absolute power.  Thomas Jefferson said he didn’t think we could have democracy unless at least 20% of the population was self-supporting on small farms so they were independent enough to be able to tell an oppressive government to stuff it.  It is very difficult to control people who can create products without purchasing inputs from the system, who can market their products directly thus avoiding the involvement of mercenary middlemen, who can butcher animals and preserve foods without reliance on industrial conglomerates, and who can’t be bullied because they can feed their own faces.


An observer today cannot help noticing the continuation of a trend that started at the beginning of the industrial revolution, a trend away from autonomy and independence for human beings and towards manipulation, consolidation, and control by large corporate entities.  The early destruction of small farms in the 18th century drove the dispossessed peasants into the cities and a bleak existence in the “dark, satanic mills” as William Blake so aptly termed them.  The propaganda in favor of becoming larger, more industrial and more centralized is so subtly pervasive and so effective that the majority of people have little idea of what has been regimented into their lives.  Massive industrial conglomerates that look upon people as anonymous passive serfs, obedient cogs in a mechanistic world, now control far too many aspects of human existence.  Circuses and bread, bread and circuses are presented as diversions for the masses today as they were for the masses of Rome.  But it is worth noting that according to the historians, it was the Roman consolidation of land into ever-larger farms that ended up destroying Roman agriculture, and resulted in the lack of bread that led to Rome’s eventual demise.


So I’d like to suggest a foe of Rome’s power as the perfect figurehead for the small family farmer holding out indomitably against the economic forces trying to subjugate the whole planet.  Our hero’s name is ASTERIX, and he is an immensely popular French comic book character.  In France there is a natural connection between the persona of Asterix and the fight against all things corporate.


Asterix and his buddy Obelix live with other members of their self-reliant community in a fictional Gallic village in northwest Brittany.  Asterix and Obelix hunt wild boar together and Obelix makes “menhirs”, those prehistoric stone monuments that are scattered all over Brittany.  The year is 50 BC.  Rome has conquered all of Gaul.  Well, not quite all because this one little village of indomitable individuals is still resisting - still holding out against all the soldiers that an ever more frustrated Caesar sends against them in a vain attempt to complete his conquest.  The village cannot be defeated because of the super-human strength the villagers get from a magic herbal potion produced by the resident village druid. 


The Asterix characters are the ideal metaphorical mascots for the small family farm:
·                 First, Rome, to whose power the villagers refuse to submit obviously represents the bigger-is-better, all conquering corporate/ industrial mentality.
·                  
·                 Second, just like these villagers, made invincible by their druid’s magic potion, we small farmers cannot be defeated because we too have a homemade magic potion. It is called compost and is the secret to the soil fertility that sustains us. Who can possibly defeat people who know that the world’s best fertilizer can be produced in quantity for free on their own farm from what grows thereabouts?
·                  
·                 Third, like the menhirs that Obelix makes, we too create ageless monuments. They are our small farms, because, in the words of British farmer George Henderson, we leave the land far better than we found it.
·                  
·    And, best of all, we have ASTERIX himself, small and tough, possessed of a confidence in his own ability. Asterix perfectly embodies the small family farmer, independent and unconquerable on the land.

Longevity Pill Now Possible






It appears from this that researchers now believe it is practical to develop a pill that will certainly mimic the factors that appear to promote optimum old age.  Combining such a pill with proper non impact cardiovascular should permit a competent old age at the least.

We have actually seen a number of key health therapies emerge just in the past year.  Also attention is been paid to other long established yet unused protocols were merited.

There are still plenty of inconvenient problems that affect a small population and are not yet resolvable, though again progress is been made.

However, I can make one particular claim.  Life expectancy for those presently alive is about to take a large jump, because circulatory problems appear solvable and cancer might have just been cured.  Dispose of those two killers and all of a sudden most folks will simply die of old age.  And as this article makes clear, abuse of tobacco and food indulgence is not much of a problem.

As posted earlier, it has been discovered that a suspension of 20 nm gold particles preferentially concentrate inside cancer cells through the blood stream, allowing electromagnetic heating to destroy the cancer cells.  Tests at MIT cured a bunch of mice outright.

With circulatory problems, it has been long known that a proper daily dose of vitamin C supplies the shortfall induced by genetic mutation unique to humanity and guinea pigs alone, which also uniquely have the same circulatory problems.  The proper dose is up to 15000 mg per day depending on body weight.  And yes it is possible to consume such amounts in orange juice in three doses after building up to it.

Where damage has occurred and where natural healing is slow, it can be remedied by taking 1500 mg of condriten sulphate which has been shown to eliminate heart attack damage in as little as three months.  For those that understand this has meant the elimination of the EKG signal for heart damage.

The science of these three protocols is specific and leaves no gray areas to confuse or argue over.  It is early days for the cancer treatment but it is true nano surgery and not biological at all.  It takes advantage of the fact that access pores for cancer cells are simply larger that healthy cells.

Now we can also expect the longevity pill as well that will at least help produce good cholesterol.


New Super-Pill Will Let Us Live to 100 — Or More
Thursday, February 4, 2010 7:49 AM


By Sylvia Booth Hubbard
When comedian Stephen Wright said, "I intend to live forever — so far, so good," he may have been on to something. A pill that will help people live to be 100 will soon be ready. The pill promises not only to let people live to be centenarians but also to keep them in good health so they can truly enjoy their extended life spans, free from diseases that plague old age.
The research team that paved the way for developing the pill, led by Dr. Nir Barzilai, a director of the Institute for Aging Research and Professor of Medicine and Molecular Genetics at Albert Einstein College of Medicine, began by looking at the DNA of a select group of centenarians. The group was composed of 500 healthy Ashkenazi Jews with an average age of 100 living in New York, and the researchers set out to determine whether they shared traits that could account for their long lives.
After examining two million genetic markers, the researchers pinpointed three "super genes" common to members of the group that are key to two things: 1) extending life beyond 100; and 2) preventing diseases common to old age. Two of the three genes enhance the production of HDL (good cholesterol), thereby reducing the risk of stroke and heart disease, while the third staves off diabetes. Those lucky enough to possess DNA that strongly features all three genes are also 80 percent less likely to develop Alzheimer's.
The study ruled out both fitness and dietary influences. In fact, to their amazement, the researchers found a third of the group were either life-long heavy smokers or were obese.
In a statement to the Daily Mail, Barzilai said, "Thirty percent of them were obese or overweight and 30 percent smoked two packs of cigarettes (a day) for more than 40 years. Because our centenarians have longevity genes, they are protected against many of the effects of the environment. That's why they do whatever they want to do and they get through anyhow."
Those who possess the longevity genes have a one in 500 chance of living to be 100, while those less fortunate have a one in 10,000 chance. By way of comparison, a child born in 2007 in the United States has a life expectancy of 78.
Barzilai believes the study findings will prove to be a boon to everyone, opening the door to lengthening average life expectancy while cutting illness in old age. "The advantage of finding a gene that involves longevity is that we can just develop a drug that will imitate exactly what this gene is doing. The biology we're trying to uncover is that if we can imitate that, then long life can be really terrific."
Barzilai revealed that several laboratories are currently racing to create a pill duplicating the effects of the three genes that promote a long healthy life. He expects a pill will be ready for testing in three years.

Ozone Hole Healing




The claims made in this article regarding the impact on aerosols and climate change is at best galloping speculation whose testability is doubtful.  It is tortured and should be tossed on the table with all those other maybes out there awaiting convincing support from Mother Nature.  You do not forget these things; however, I would sooner chase gold mines.

 

Of more importance, it is good to see the ozone layer shrink.  This continues to confirm the CFC hypothesis of causation and plausibly supports the decision made a generation ago to take Freon out of the industrial system.  From that perspective this is good news.  We do not have to return to the drawing board on this one at least.

 

Folks forget that it took a leap of faith to link Freon directly to the ozone hole.  They may still be wrong.  And eliminating Freon is no bad thing.


My biggest doubt with the theory itself was that it was based on a lack of historical data.  Ozone holes may be decadal phenomena going on forever and we would simply not know.  So on short term data we got rid of Freon, hoping we were right.

 

Our more recent climate activists forget that CO2 is not Freon.  CO2 is an integral component of global biome and is used by everything.  We even know that the optimum for atmospheric concentration is around 1000 ppm, over twice present levels.  We have a long ways to go and the industrial carbon age may optimistically add another 100 ppm before it runs its course.

 

Presuming we then terraform the Earth properly converting deserts and dry lands into productive woodlands and the like we will consume all that carbon and then some.  I can see the day when it is felt wise to ignite coal fires and to stimulate hydrate release in order to maintain better CO2 levels.

 

Ozone hole healing could cause further climate warming

 

Jan 27, 2010

The hole in the ozone layer is now steadily closing, but its repair could actually increase warming in the southern hemisphere, according to scientists at the University of Leeds.
The Antarctic ozone hole was once regarded as one of the biggest environmental threats, but the discovery of a previously undiscovered feedback shows that it has instead helped to shield this region from carbon-induced warming over the past two decades.
High-speed winds in the area beneath the hole have led to the formation of brighter summertime clouds, which reflect more of the sun's powerful rays.
"These clouds have acted like a mirror to the sun's rays, reflecting the sun's heat away from the surface to the extent that warming from rising carbon emissions has effectively been cancelled out in this region during the summertime," said Professor Ken Carslaw of the University of Leeds, who co-authored the research.
"If, as seems likely, these winds die down, rising CO2 emissions could then cause the warming of the southern hemisphere to accelerate, which would have an impact on future climate predictions," he added.

The key to this newly-discovered feedback is aerosol – tiny reflective particles suspended within the air that are known by experts to have a huge impact on climate.
Greenhouses gases absorb infrared radiation from the Earth and release it back into the atmosphere as heat, causing the planet to warm up over time. Aerosol works against this by reflecting heat from the sun back into space, cooling the planet as it does so.
Beneath the Antarctic ozone hole, high-speed winds whip up large amounts of sea spray, which contains millions of tiny salt particles. This spray then forms droplets and eventually clouds, and the increased spray over the last two decades has made these clouds brighter and more reflective.
As the ozone layer recovers it is believed that this feedback mechanism could decline in effectiveness, or even be reversed, leading to accelerated warming in the southern hemisphere.
"Our research highlights the value of today's state-of-the-art models and long-term datasets that enable such unexpected and complex climate feedbacks to be detected and accounted for in our future predictions," added Professor Carslaw.
The Leeds team made their prediction using a state-of-the-art global model of aerosols and two decades of meteorological data. The research was funded by the Natural Environment Research Council's Surface Ocean-Lower Atmosphere Study (UK SOLAS) and the Academy of Finland Centre of Excellence Programme.

Bill Gates on Energy Innovation





First we are not quoting the text from Bill’s blog here.  You will have to chase that elsewhere.  However Sean is making some very good points here and is a reminder of thing we all should understand.

I have spent much of the past few decades advising and assisting business innovation and startups.  It is only recently that it has become possible to actually fund the sort of budgets needed to properly explore innovative industrial solutions.

Launching an innovative business such as Microsoft was done for chump change and there were no capital barriers to the project that were significant.

Now suppose you have an innovative method to massively improve the manufacture of pulp and paper.  I use this example because I was there.  The operational test requires two to five million in capital improvements and then a plant shut down and switch over for at least six months costing half the year’s sales.  Your task is to convince the board of directors that they should do this.  By the way the improvement is modestly incremental in terms of profitability but removes that nasty sulphur smell around the plant bothering all the local residents.  The point is that the money will not exist in these circumstances unless the industry itself bands together to create a shared solution.  That is a pretty tall order for a couple of lab rats and a garage.

It is easy to talk innovation in capital intensive industries, except the process is naturally glacial because of exactly this problem.

North America and Europe is in the midst of an industrial innovation period right now (that means the snail appears to be moving) because we just shipped every obsolete factory we could locate off to China and India.  We now have tightened up the environmental rules also making the field level inside this market because we could after selling off the legacy infrastructure.

The visible innovation is coming in heavy manufacturing and aerospace and the energy industry.  None of it is happening in a garage though.

Bill Gates thinks about energy innovation

2 FEB 2010 11:24 AM


Bill Gates has written on his blog that we need “innovation, not just insulation” in order to reduce CO2 to manageable levels. His motivation is robust, but his thinking is ... far from clear. Because he’s Bill Gates, this is sure to attract attention, but even if he weren’t, this is worth talking about. It illustrates the deep misunderstandings that most of us have about the energy sector, the possibilities for reform, and—at a much larger level—how our economy works.

What Gates gets right

Let’s start with his core thesis: Gates argues that while we might get to 30% CO2 reduction by 2020 with lots of efficiency and small-scale tweaks to the system, the long-term goal of 80% reduction by 2050 is going to be much harder—indeed, impossible without massive changes in the way we use energy, the types of energy we use, and the technologies we use for energy conversion. Ergo, we need to focus our efforts on large-scale innovation in zero-carbon technologies.
At an abstract level, this is an important point worth screaming from the rooftops. No one should define success solely by our ability to meet intermediate goals. Passing CO2 legislation is a critical first step. Hitting 2020 targets is a key second step. But neither of those steps matter if we fail on the long-term objective. This approach to long-term planning was ubiquitous amongst political leaders in an earlier era (George Marshall, anyone?) but sadly absent today. My God, do we need more of that.
What Gates gets wrong

Unfortunately, having spotted a problem, he gets the diagnosis wrong, in ways that are far too common among damned near every Serious Person who thinks about our energy system but doesn’t live in its trenches. It’s too flat for me to ski anywhere near my home in Chicago—but I’m not foolish enough to spend my weekends hauling dirt. Similarly, the lack of innovation in our energy sector doesn’t necessarily imply that the solution is simply to do more innovating. Rather, we have to start by asking a deeper question: why is this industry so devoid of entrepreneurial creativity? Solve that question and the innovation will follow. Avoid that question and we’re molding mountains in Milwaukee.
Gates is guilty of nothing more than a common habit of mind: We see the way that hard work, entrepreneurship, and innovation drive large-scale, socially beneficial change (especially in consumer electronics) and conclude that this recipe must apply to other industries. Ten years ago, I didn’t own a cell phone, but today I have a Blackberry. Meanwhile, that coal plant down the road is 60 years old and competitive. Can’t we just innovate to make it obsolete?
Yes and no.
Yes, the industry is devoid of real innovation. Write a list of the great technological and entrepreneurial leaders in the energy industry and you’re likely to end up with a list of cadavers. Edison, Tesla, Westinghouse ... great men all, and all dead. Where are the Bill Gates, Michael Dells, and Fred Smiths of this industry? Where is the “killer app” of the last 30 years? How much greater would our lives be if this industry attracted the innovation we’ve come to take for granted in the rest of our economy?
But no, the solution to this is not to throw money at innovation. Rather, it is to understand why smart, ambitious, innovative entrepreneurs have consistently elected to pursue career paths in other industries.The Atlantic recently asked whether CEOs matter and noted that some industries (like Mr. Gates’) depend hugely on their CEOs while others (like electric utilities) don’t, because in the former case the CEO is “unconstrained” while in the latter case they are no more than “titular figureheads.” Now suppose that you are an ambitious entrepreneur, seeking to change the world. Would you rather be unconstrained or a titular figurehead? Is it any surprise that innovation is absent in such a industry?

This, at core, is why efficiency matters—and why it’s so troubling to hear Mr. Gates to write off energy efficiency with lines like “you can never insulate your way to anything close to zero.”
Of course you can’t. But there are two huge holes in that statement. First, it assumes that efficiency is simply about how people use energy rather than how we generate useful energy. When our electric sector is only 1/2 as fuel efficient today as it was in 1910, generation efficiency is key. You may not be able to insulate your way to zero, but you can make up at least half the ground between here and zero simply by deciding to stop throwing fuel away.
The second point is more critical: we have piles of efficient, profitable technologies that aren’t being deployed today, for a host of reasons ranging from utility regulation to environmental permitting rules—all of which may have been appropriate for an earlier era but are hopelessly obsolete today.
Given that reality, what would it mean if we innovated some great new technology? That’s easy—we’d simply throw another technology on a line of undeployed (but otherwise really cool) technologies.
That’s a hard pill to swallow. It flies in the face of our perceptions about the efficiency of our economy, and it flies in the experience of leaders like Gates who have spent their careers in rapidly changing, competitive, relatively low barrier-to-entry industries where the kind of stasis seen in the energy sector would drive you to obsolesence, then bankruptcy. But the discomfort of the reality has to be confronted. Like it or not, we are generating and distributing power with the equivalent of a 1980 Wang computer. And while an Intel 386 chip with Office 1995 isn’t the end goal, understanding and removing the barriers to deploying that particular technology is a prerequisite for all that follows.
In short, energy efficiency is the canary in the coal mine. Once we remove the barriers to innovation in the energy sector, we’ll see a flood of efficiency, a flood of sexy CEOs (pick me!), and a flood of those new technologies. But the cart can’t lead the horse.

Forests Growing Faster





Son of a Bitch!!!  We have real data here folks that is properly gathered and massaged.  I have been getting awfully tired of the paucity of proper data in the climate game in particular, particularly after discovering just how terribly compromised the national weather data is.  This is actually better than good.  The twenty year mapping over a range of populations and ages allows the production of a pretty secure set of data curves.

We know that the climate itself is warmer during this past twenty years and the longer growing season is a result of that.  We also know that the CO2 content has risen and it is here quantified here at 12%.  Both factors are natural growth drivers and are certainly at work.  Again I remind my readers that this does not actually link the two factors.  At present we are having the climate cooling on the northern continents while CO2 continues to rise unabated.

Even more interesting, he has defined the sustainable annual forest production of wood fiber.  I do not know if that also includes the expanded root mass which will be an equal amount.  It is a good working number for forest management.  It tells us that we can thin a forest an average of ten to fifteen tons every several years which is actually a good removal rate and may possibly be superior to clear cutting procedures.  That would include waste converted into wood chips.

We may see forests returned to well managed private woodlots sooner than we think.  This sort of economic model starts to work and can be integrated into large operations rather well.  In fact I think the major problem in forest management is the cost of appropriately spaced trees at the beginning of the cycle.  Once that is done, nature takes care of the rest.



Forests Are Growing Faster, Ecologists Discover; Climate Change Appears to Be Driving Accelerated Growth

ScienceDaily (Feb. 2, 2010) — Speed is not a word typically associated with trees; they can take centuries to grow. However, a new study in the Proceedings of the National Academy of Sciences has found evidence that forests in the Eastern United States are growing faster than they have in the past 225 years. The study offers a rare look at how an ecosystem is responding to climate change.


For more than 20 years forest ecologist Geoffrey Parker has tracked the growth of 55 stands of mixed hardwood forest plots in Maryland. The plots range in size, and some are as large as 2 acres. Parker's research is based at the Smithsonian Environmental Research Center, 26 miles east of the nation's capital.

Parker's tree censuses have revealed that the forest is packing on weight at a much faster rate than expected. He and Smithsonian Tropical Research Institute postdoctoral fellow Sean McMahon discovered that, on average, the forest is growing an additional 2 tons per acre annually. That is the equivalent of a tree with a diameter of 2 feet sprouting up over a year.

Forests and their soils store the majority of the Earth's terrestrial carbon stock. Small changes in their growth rate can have significant ramifications in weather patterns, nutrient cycles, climate change and biodiversity. Exactly how these systems will be affected remains to be studied.

Parker and McMahon's paper focuses on the drivers of the accelerated tree growth. The chief culprit appears to be climate change, more specifically, the rising levels of atmospheric CO2, higher temperatures and longer growing seasons.

Assessing how a forest is changing is no easy task. Forest ecologists know that the trees they study will most likely outlive them. One way they compensate for this is by creating a "chronosequence" -- a series of forests plots of the same type that are at different developmental stages. At SERC, Parker meticulously tracks the growth of trees in stands that range from 5 to 225 years old. This allowed Parker and McMahon to verify that there was accelerated growth in forest stands young and old. More than 90% of the stands grew two to four times faster than predicted from the baseline chronosequence.

By grouping the forest stands by age, McMahon and Parker were also able to determine that the faster growth is a recent phenomenon. If the forest stands had been growing this quickly their entire lives, they would be much larger than they are.

Parker estimates that among himself, his colleague Dawn Miller and a cadre of citizen scientists, they have taken a quarter of a million measurements over the years. Parker began his tree census work Sept. 8, 1987 -- his first day on the job. He measures all trees that are 2 centimeters or more in diameter. He also identifies the species, marks the tree's coordinates and notes if it is dead or alive.

By knowing the species and diameter, McMahon is able to calculate the biomass of a tree. He specializes in the data-analysis side of forest ecology. "Walking in the woods helps, but so does looking at the numbers," said McMahon. He analyzed Parker's tree censuses but was hungry for more data.

It was not enough to document the faster growth rate; Parker and McMahon wanted to know why it might be happening. "We made a list of reasons these forests could be growing faster and then ruled half of them out," said Parker. The ones that remained included increased temperature, a longer growing season and increased levels of atmospheric CO2.

During the past 22 years CO2 levels at SERC have risen 12%, the mean temperature has increased by nearly three-tenths of a degree and the growing season has lengthened by 7.8 days. The trees now have more CO2 and an extra week to put on weight. Parker and McMahon suggest that a combination of these three factors has caused the forest's accelerated biomass gain.

Ecosystem responses are one of the major uncertainties in predicting the effects of climate change. Parker thinks there is every reason to believe his study sites are representative of the Eastern deciduous forest, the regional ecosystem that surrounds many of the population centers on the East Coast. He and McMahon hope other forest ecologists will examine data from their own tree censuses to help determine how widespread the phenomenon is.

Super Hard Diamonds Found






This discovery is effectively predicted by work done on graphene in which superior strength was observed.  Here nature has welded together stacks of graphene to form diamonds and yes they are decidedly stronger.

Now imagine a cutting edge formed by stacking sheets of graphene together to produce a blade like structure and somehow compressing them to form a diamond structure.  We can at least imagine it and it provides additional goals for research.

No one has had luck in quantizing all this yet and I am sure it will be a while.  At least we now have a device able to test a diamond by scratching it :-)


Super Hard Diamonds Found in Meteorite

The ultra-hard rocks may not end up on your finger, but they could help scientists learn how to create harder diamonds in the lab.

By Larry O'Hanlon | Tue Feb 2, 2010 04:17 AM ET

THE GIST:
·                        Two new ultra-hard types of diamond have been found in a meteorite from Finland.
·                        The ultra-hard carbon crystals were created out of graphite under the intense heat and pressure of the meteorite impact.
·                        Though the new diamonds are definitely harder than regular diamonds, the crystals were too small to test for their exact hardness.


Researchers using a diamond paste to polish a slice of meteorite stumbled onto something remarkable: crystals in the rock that are harder than diamonds.
A closer look with an array of instruments revealed two totally new kinds of naturally occurring carbon, which are harder than the diamonds formed inside the Earth.

"The discovery was accidental but we were sure that looking in these meteorites would lead to new findings on the carbon system," said Tristan Ferroir of the Universite de Lyon in France.

Ferroir is the lead author of a report in the new diamond in the Feb. 15 issue of the journal Earth and Planetary Science Letters.

The researchers were polishing a slice of the carbon-rich Havero meteorite that fell to Earth in Finland in 1971. When they then studied the polished surface they discovered carbon-loaded spots that were raised well above the rest of the surface –- suggesting that these areas were harder than the diamonds used in the polishing paste.

"That in itself is not surprising," said diamond researcher Changfeng Chen of the University of Nevada in Las Vegas. He explained that sometimes during the shock of impact graphite can create jumbled "amorphous" zones that can resist diamonds, at least those coming at them from one direction.
But what apparently happened in the Havero meteorite is that graphite layers were shocked and heated enough to create bonds between the layers -- which is exactly how humans manufacture diamonds, Chen explained.
Ferroir's team took the next step and put the diamond-resistant crystals under the scrutiny of some very rigorous mineralogical analyzing instruments to learn how its atoms are lined up. That allowed them to confirm that they had, indeed, found a new "phase" or polymorph of crystalline carbon as well as a type of diamond that had been predicted to exist decades ago, but had never been found in nature until now.
"The new structure is very interesting," Chen told Discovery News. "It gives us some clues so we can try to make it in the laboratory, and then investigate it."
Among the things that would be interesting to learn, Chen said, is how hard are the new kinds of diamonds. The sample from the meteorite was far too small to test for hardness, except to show that it is certainly harder than regular diamonds.

"The only evidence we have for a higher hardness than diamond is the fact that we polished the rock section with a diamond paste and that our polymorph and polytypes were not polished by this material," said Ferroir. "This why we do think that its hardness is harder than diamond."
However, there is no way at the present to compare them to the artificial ultra-hard diamonds known as lonsdaleite and boron nitride, Ferroir said.
