300-Million-Year-Old Forest Discovered in China

300-Million-Year-Old Forest Discovered Preserved in Volanic Ash

ScienceDaily (Feb. 20, 2012) — Pompeii-like, a 300-million-year-old tropical forest was preserved in ash when a volcano erupted in what is today northern China. A new study by University of Pennsylvania paleobotanist Hermann Pfefferkorn and colleagues presents a reconstruction of this fossilized forest, lending insight into the ecology and climate of its time.

Pfefferkorn, a professor in Penn's Department of Earth and Environmental Science, collaborated on the work with three Chinese colleagues: Jun Wang of the Chinese Academy of Sciences, Yi Zhang of Shenyang Normal University and Zhuo Feng of Yunnan University.

Their paper was published this week in the Early Edition of the Proceedings of the National Academy of Sciences.

The study site, located near Wuda, China, is unique as it gives a snapshot of a moment in time. Because volcanic ash covered a large expanse of forest in the course of only a few days, the plants were preserved as they fell, in many cases in the exact locations where they grew.

"It's marvelously preserved," Pfefferkorn said. "We can stand there and find a branch with the leaves attached, and then we find the next branch and the next branch and the next branch. And then we find the stump from the same tree. That's really exciting."

The researchers also found some smaller trees with leaves, branches, trunk and cones intact, preserved in their entirety.



Due to nearby coal-mining activities unearthing large tracts of rock, the size of the researchers' study plots is also unusual. They were able to examine a total of 1,000 m² of the ash layer in three different sites located near one another, an area considered large enough to meaningfully characterize the local paleoecology.

The fact that the coal beds exist is a legacy of the ancient forests, which were peat-depositing tropical forests. The peat beds, pressurized over time, transformed into the coal deposits.

The scientists were able to date the ash layer to approximately 298 million years ago. That falls at the beginning of a geologic period called the Permian, during which Earth's continental plates were still moving toward each other to form the supercontinent Pangea. North America and Europe were fused together, and China existed as two smaller continents. All overlapped the equator and thus had tropical climates.

At that time, Earth's climate was comparable to what it is today, making it of interest to researchers like Pfefferkorn who look at ancient climate patterns to help understand contemporary climate variations.

In each of the three study sites, Pfefferkorn and collaborators counted and mapped the fossilized plants they encountered.In all, they identified six groups of trees. Tree ferns formed a lower canopy while much taller trees -- Sigillaria and Cordaites -- soared to 80 feet above the ground. The researchers also found nearly complete specimens of a group of trees called Noeggerathiales. These extinct spore-bearing trees, relatives of ferns, had been identified from sites in North America and Europe but appeared to be much more common in these Asian sites.

They also observed that the three sites were somewhat different from one another in plant composition. In one site, for example, Noeggerathiales were fairly uncommon, while they made up the dominant plant type in another site. The researchers worked with painter Ren Yugao to depict accurate reconstructions of all three sites.

"This is now the baseline," Pfefferkorn said. "Any other finds, which are normally much less complete, have to be evaluated based on what we determined here."

The findings are indeed "firsts" on many counts.

"This is the first such forest reconstruction in Asia for any time interval, it's the first of a peat forest for this time interval and it's the first with Noeggerathiales as a dominant group," Pfefferkorn said.

Because the site captures just one moment in Earth's history, Pfefferkorn noted that it alone cannot explain how climate changes affected life on Earth. But it helps provide valuable context.

"It's like Pompeii: Pompeii gives us deep insight into Roman culture, but it doesn't say anything about Roman history in and of itself," Pfefferkorn said. "But on the other hand, it elucidates the time before and the time after. This finding is similar. It's a time capsule and therefore it allows us now to interpret what happened before or after much better."

The study was supported by the Chinese Academy of Science, the National Basic Research Program of China, the National Natural Science Foundation of China and the University of Pennsylvania.

A show of peace and harmony

CERITALAH By KARIM RASLAN

In London, the British Museum puts on an exhibition on the haj and all aspects of the pilgrimage through the ages. Nearby, artifacts of Buddhist and Hindu kingdoms are on show. It is a place that unites people of diverse faiths and backgrounds.

MECCA is a city of surprises. The landscape may be bleak, but everything changes once you’re within the city as the extraordinarily rich texture of the Muslim world unfolds around you, from the sleek magnificence of the Masjid al-Haram to the liveliness of the street markets and souks.

Ten years ago, when I first visited the Holy Land for an umrah swiftly followed by the full haj a few months later, I remember being enthralled by the amazing diversity of my fellow pilgrims: their weather-worn faces were redolent of history, romance and drama.

There were dignified-looking Persian clerics in their long flowing black gowns, ebullient West African traders who were tall, big-boned and wearing white robes, deeply tanned Tajiks and tens of thousands of Bangladeshi villagers.

Regal Sudanese rubbed shoulders with Baluch and Pathan tribesmen, haughty-looking Cairo housewives, Levantine shopkeepers, Javanese and the occasional European or American.

Watch Obama's Video:

 (This is a video that Sean Hannity of FOX News has been trying to show that has consistently been blocked by the Obama Administration for several weeks. Watch it now before it gets pulled from the Internet!)

There was a moment when I felt as if the entire world was alongside me as I circumambulated the Kaaba.

Even back then, the city was undergoing tremendous change as increased prosperity in the Muslim world fuelled the number of pilgrims.



Roads and tunnels were being blasted into existence; buildings were being torn down or hastily constructed — a mishmash of styles that left me wondering what the originals looked like.

All of this came back to me as I walked around the British Museum’s very elegant exhibition titled Hajj: journey to the Heart of Islam (open until mid-April).

For anyone interested in understanding the haj, the exquisitely-curated show (in partnership with Saudi Arabia’s King Abdulaziz Public Library and sponsored by HSBC Amanah) is a superb eye-opener.

The haj is one of the Five Pillars of Islam, something every Muslim must do at least once in his or her lifetime if possible.

For many Muslims, it is one of the most important events in their lives, a journey to save and sacrifice for.

Last November, it’s estimated that more than three million Muslims converged on Mecca for the five-day ritual, one of the largest annual human assemblies in the world.

The British Museum’s exhibition is thorough and thought-provoking. Located inside the museum’s iconic Atrium, the exhibition focuses on all aspects of the pilgrimage through the ages.

The displays ranged from the haj’s origins and rituals, down to the long (and often perilous) journeys that the pilgrims were forced to take.

Indeed, much of the exhibition is devoted to the great distances and dangers that the pilgrims were forced to brave – crossing the Sahara and Gobi deserts or traversing the Indian Ocean.

Despite the diversity, there remains an underlying unity, an inexplicable oneness of sorts.

Of course, the ihram (white pilgrims’ robes) and the starkness of the landscape reinforce a sense of purity and simplicity of purpose.

But then again, maybe it’s also present in the determination and resolute faith of those undertaking the haj – a fixity of purpose that unites pilgrims whether they’re from Mali, Azerbaijan or China, not to mention the rich and the poor.

Having had my fill of the exhibition, I wandered out of the Atrium and onto the Asia exhibits in the gorgeously laid-out Hotung Gallery.

Artefacts imbued with faith were also on display here: Thai and Khmer sculptures of the Buddha stood next to bronze statues from Hindu temples in southern India.

And yet for some reason, I, as a Muslim from South-East Asia also felt very much at ease as I strolled past these historic items.

Could it have been because they were also part of my heritage and my past?

I also found it profound that the haj and Islam – a faith of complete submission to Allah – should be so celebrated in a museum, the product of the humanistic enlightenment with its opposing and single-minded focus on mankind.

Another thought struck me: the majority of the visitors to the exhibition were clearly non-Muslims, people of many different faiths who were eager and sufficiently open to want to learn more about Islam.

It occurred to me that I would have to wait a very long time to see a similar exhibition on, say, Easter or Hindu rituals at a major museum in a majority-Muslim city such as Cairo, Karachi or even Kuala Lumpur and this thought saddened me.

So, in a corner of London not far from the traffic of Oxford Street and the echoing courtyards of the Inns of Court, I came across an exhibition that united peoples of diverse faiths and backgrounds – uniting them all momentarily in a quest for knowledge, as a museum became a haven of harmony and peace.

Why Is Creativity More Important Than Capitalism?

Creativity (Photo credit: Mediocre2010)

Haydn Shaughnessy, ForbesContributor

Do you know your creativity quotient?  Creativity sounds a little weak, a touchy-feely topic, but it turns to be one of the most important memes of the past 100 years, and very definitely ranks alongside concepts (or ideologies) like capitalism in the pantheon of big ideas.

I admit to being a creativity sceptic. When it came into vogue thirty years ago I cringed. Creative? What’s wrong with busy? Or dedicated. Or hard working. But creativity’s rise – measured by the use of terms “creative” and “creativity” in Google‘s nGram database – has been relentless for over a century. It is NO fad.

For those that don’t know it the nGram database contains roughly 4% of all books ever published, in the case of this data in the USA and Britain.

The problem of creativity – how to manifest it in disciplined environments – hasn’t changed much during that period.



But if you look at the chart below you can get a sense of its importance.  The use of “creative” dwarfs terms like technological progress and scientific progress.

In fact digging a little deeper I found out:

The use of the language of creativity is increasing when people write about scientific progress. Progress itself is a term in declining use, seemingly replaced by the idea of creativity, at least in the sciences. You can’s see that from the chart – to get to that data I examined the use of a variety of terms over the period 1960 – 2010.

The best Google nGram data goes up to 2000 but I checked search interest in these terms, post 2000, and the patterns continue.

The use of creativity is increasing in business and management literature, declining where people write about religion and education, and of course rising when people write about cities.

Jonah Leher’s book Imagine underlines the slacker nature of creativity but also it’s importance. Let’s face it the quest to be more creative as a society is as old as (modern) business.

Creativity is big in entertainment too, naturally, if entertainment is taken to include art and music but surprise, surprise the use of the term in entertainment declined in the period 1981 – 2000, while it increased in association with business and management.

Is all this just a reflection of publishers pumping more books out? No, all data is normalised.

Is there anything to conclude from the data?  The themes of creativity have been pretty consistent down the years – how organizations stifle it, how necessary it is, and how it creates risk.

The one lacking ingredient seems to be a creative answer to those problems, though I think we may be on the cusp of one (more of that later in the week).

Let’s all be Malaysians first & Proud to be Malaysian !!

HOW right Wong Sai Wan is in The Star column “How frail our unity is”, that our so-called “togetherness and unity” is only “skin deep” and at “surface level” at best.

As a Malaysian who has lived in this country for 60 years, I can only say that the depth of our “unity” is receding as the years roll by instead of becoming deeper. It is not only “skin deep”.

Racial and religious politics have taken a toll on the fabric of society as more and more people are identifying themselves first by “race and religion” instead of nationality (“Malaysian”).

If we do not arrest this slide, we will become a nation divided. We must make serious efforts to stem this tide.

I believe there are three main areas we need to look into, and politicians must be on the frontline to stem this tide.

Politicians from both sides must stop harping on our differences, be it religious or racial.

Religious leaders must ensure that religion is not forced onto others, or making one religion more important than the other.

Every effort must be made by society at large to view ourselves as “Malaysians first” rather than by race.

Indonesia is a classic example of how the different races view themselves as “ Indonesians first”. Ask a Chinese in Indonesia who he is and the reply will be “I am Indonesian”.

The media, like Wong said, must ensure that it does not play up sentiments of any kind but report the news as it is, from a “human view point” rather than race or religion.

In schools, especially, the heads must ensure that the children view each other as “ classmates” rather than by race.

There must also be a healthy “mix” at all levels of employment of the people of different races.

This will help us view each other as “ workmates” rather than racial individuals.

1Malaysia can only be achieved when we are “ Malaysian first” rather than portraying ourselves by our race.

All forms or documents must not highlight race or religion unless absolutely necessary.

Unity can only be strengthened if efforts are made, not through slogans, advertisements or banners.

Let us as Malaysians take this step to view each other as just that. I am Malaysian.

MICHEL FREDICK WRIGHT, Batu Caves.

Proud to be Malaysian

I WRITE in response to “Liow: Govt wants more ethnic groups to join the civil service” (The Star, Feb 20).

In that article, Gerakan Youth secretary-general Dr Dominic Lau was quoted as saying that “unlike Americans, who were proud to call themselves Americans regardless of their race, not many Malaysians could identify themselves as Malaysian first”.

That is a totally outrageous remark. I would say Malaysians are proud of their nationality.

This is my personal experience being a student overseas.

I am an international postgraduate student in Brisbane, Australia.

Whenever people ask where I come from, I would proudly tell them I’m a Malaysian, coming from Ipoh. Some are confused as my ethnicity is Chinese yet I’m not from China, Taiwan or Hong Kong.

I elaborate by saying my ancestors came from China and I’m a third generation Chinese in Malaysia. But China is not my country. My country is Malaysia.

The fact that I’m a Malaysian makes me unique, being able to communicate not only in Mandarin and Cantonese but also in Bahasa Malaysia and English.

I have no problems communicating with people from various backgrounds, all thanks to my upbringing in Malaysia.

I’m not denying my Chinese roots of course, but when people ask my race, I say I’m Malaysian, and by ethnicity I’m a Malaysian Chinese.

There are many Malaysian student bodies in Queensland’s universities and we are all proud of telling the world that we are Malaysian. We don’t feel embarrassed being Malaysian.

During Malaysian roadshows, we proudly display the Malaysian flag, introduce Malaysian cultures as well as the great heritage of Malaysia.

Malaysia is blessed with natural resources, peace and diversity. Are we not proud being Malaysian? Yes we are!

I think the problem is back in Malaysia where politicians tend to separate the rakyat based on ethnicity.

Each political party champions only its people – Party A for Malay, Party B for Chinese, Party C for Indian, and the rest for “lain-lain”. But we are Malaysian.

It is not that we cannot identify ourselves as Malaysian first but when we fill up forms – bank forms, government documents – there’s always a column for race.

It makes it seem as if we will be treated differently if we state our ethnicity.

After half a century of independence, we are still forced to identify ourselves based on ethnicity.

Now, if we don’t call ourselves Malaysian first, is it the rakyat’s fault or the politician’s fault?

We are Malaysian, and we couldn’t be prouder, if you can’t hear us, we shout a little louder ... 1Malaysia!!!

WONG WENG-YEW, Brisbane, Australia.

Trade war looms over EU tax

Global Trends By MARTIN KHOR

This week, 26 countries will meet to organise retaliation against the EU over its move to tax airlines for their emissions. This may be the first salvo in dangerous trade wars fought over climate change. 

A TRADE war is looming over the European Union’s move to impose charges on airlines on the basis of the greenhouse gases they emit during the planes’ entire flights into and out of European airports.

Many countries whose airlines are affected – including China, India, Malaysia, Nigeria, South Africa, Egypt, Brazil and the United States – consider this to be unfair or illegal or both.

Since their protests have not yielded results, officials of 26 countries are meeting in Moscow this week to discuss retaliatory action against the EU.

The EU’s move, which took effect on Jan 1, and the tit-for-tat actions by the offended countries, is the first full-blown international battle over whether countries can or should take unilateral trade measures on the ground of addressing climate change.



Developing countries in particular have been concerned over increasing signs that the developed countries are preparing to take protectionist measures to tax or block the entry of their goods and services on the ground that greenhouse gases above an acceptable level are emitted in producing the goods or undertaking the service.

Besides the airlines case, several other measures are being planned by the EU or by the United States that will affect the cost of developing countries’ exports.

In fact, trade measures linked to climate change may become the main new sources of protectionism.

The EU’s aviation emissions tax is thus an important test case, and this could explain the furious and coordinated response by the developing countries, which form the majority of the protesting 26 nations meeting in Moscow.

The countries are particularly angry that the EU is imposing a charge or tax on emissions from the entire flight of an airline, and not just on the portion of the flights that are in European airspace.

The EU action takes effect by including the aviation sector (and airlines of all countries) in the European Emissions Trading Scheme.

Beyond a certain level of free allowances, the airlines have to buy emission permits depending on the quantity emitted during the flights.

As the free allowances are reduced in future years, the cost to be paid will also jump, thus increasingly raising the price of passenger tickets and the cost of transporting goods, and affecting the profitability or viability of the airlines.

The China Air Transport Association has estimated that Chinese airlines would have to pay 800 million yuan (RM387mil) for 2012, the first year of the EU scheme, and that the cost will treble by 2020.
The total cost to all airlines in 2012 is estimated at 505mil (RM2bil), at the carbon price of 5.84 (RM23.30) per tonne last week, according to Reuter Thomsom Carbon Point.

Last September, when the carbon price was 12 (RM48) per tonne, Carbon Point had estimated the cost to be 1.1bil (RM4.4bil) in 2012, rising to 10.4bil (RM41.6bil) in 2020.

While this may generate a lot of resources for Europe, airlines in developing countries will in turn have to pay a lot.

There are many reasons why the concerns of the affected countries are justified, as shown by Indian trade law expert R.V. Anuradha, in her paper on Unilateral Measures and Climate Change.

Since each country has sovereignty over the airspace above its territory (reaffirmed by the Chicago Convention), the EU tax based on flight portions that are not on European airspace infringes the principle of sovereignty.

The UN Climate Convention’s Kyoto Protocol states that Annex I parties (developed countries) shall pursue actions on emissions arising from aviation through the International Civil Aviation Organisation (ICAO).

Consistent with the principle of common but differentiated responsibilities, only Annex I countries are mandated to have legally binding targets. This UNFCCC principle is violated by the EU requirement affecting airlines from both developed and developing countries.

ICAO members have been discussing, but have yet to reach agreement on, actions to curb aviation emissions. Last October, 25 countries issued a paper in ICAO protesting against the EU measure.

While the United States has challenged the EU action in a European court, China has ordered its airlines not to comply with the EU scheme unless the government gives them permission.

In addition, retaliation measures such as imposing levies on European airlines and reviewing the access and landing rights agreements with European countries are being considered by the 26 countries.

What happens in this aviation case is significant because there are many other unilateral measures linked to climate change being lined up by developed countries.

These include the EU plan to impose charges on emissions from maritime bunker fuel, a US Congress bill that requires charges on energy-intensive imports from developing countries that do not have similar levels of emissions controls as the US, and several schemes involving labels and standards linked to emissions.

If these unilateral measures are implemented, then developing countries will really feel they are being victimised for a problem – climate change – that historically has been largely caused by the developed countries.

Moreover, this will lead to a growing crisis of both the climate change regime and the multilateral trade regime.
