How do you say "dam(n) it" in Chinese ... and in Nepali too?

In case you forgot this post from just about a month ago, I quoted at length from an op-ed in which the author expressed serious concerns over China's dam building frenzy.  The author's solution was an easy and simple one:
The solution to these complex problems is simple: Since these enormous projects are state-run and state-financed, China’s leaders can cancel them at will.
That was a month back.

And then something big happened a week ago. So big it measured a 7.9 on the Richter Scale. Yes, the earthquake in Nepal.

In addition to the thousands dead, thousands missing, and the destruction to property, the quake rocked the dam world too.
Two workers at the Rasuwagadhi Hydropower station were killed and several injured in the quake, according to a statement released by the plant’s operator China Three Gorges Co.
And:
Rasuwagadhi, about 67.5 km from the quake epicentre, is one of three dams in Nepal under construction by Three Gorges Corp, according to the company’s website.
The New Yorker has a lot more analysis to offer.
Other deadly earthquakes will almost certainly strike the region, and the damage at Rasuwagadhi raises the question of whether a future quake in the Himalayas might precipitate a dam collapse that could send thousands of tons of water and rubble crashing downstream, piling horror upon catastrophe. The likelihood of such an event is growing because, simply put, more and more dams are being built in one of the world’s most active earthquake zones. More than four hundred dams are planned or are under construction in steep Himalayan valleys in China, India, Pakistan, and Bhutan, in one of the biggest waves of dam construction the world has ever seen.
More than four hundred dams?  In an earthquake area?  Where access even during the good days is not easy?  
Nepal, which has an abundance of as-yet-undammed rivers, a chronic shortage of energy (nineteen-hour blackouts are routine across the country), no spare cash, and little engineering expertise, is an obvious target for these regional investors. But then, there are the earthquakes. The Himalayas are the world’s highest and youngest mountains, the product of a slow-motion collision, fifty million years ago, between India—then an island—and the Eurasian landmass that forced what became the spectacular mountains upwards. India still pushes several inches northward a year, and stresses on the mountain region’s multiple fault lines regularly result in severe earthquakes that send avalanches crashing into steep river valleys, carrying away precarious roads, bridges, and other infrastructure.
What could possibly go wrong, right?  Oh wait, in addition to all these natural hazards, we humans add more to the stress.  The geologic stress, that is:
Geologists argue that the risks of building dams in earthquake zones go well beyond an earthquake-induced collapse. Earthquakes trigger landslides that can block rivers or change their course, which would also impact the operation of a hydrodam. But the most fiercely debated risk, since the 7.9-magnitude Sichuan earthquake in 2008, which killed seventy thousand people and left nearly twenty thousand missing, is that of “reservoir-induced seismicity”—the theory that the weight of water behind a dam, coupled with the seeping of water into fissures in rocks below, can produce shearing stress strong enough to worsen, or trigger, an earthquake. The Zipingpu dam, a five-hundred-and-eleven-foot-high structure on the Min River and the largest dam in Sichuan Province, was implicated in the 2008 earthquake.
What's the bottom-line then?
Saturday’s quake demonstrated how vulnerable infrastructure projects remain in the unsettled Himalayas.
If only we thought about economic development that is not completely at the expense of nature, and if only invested in sustainable development.  But, there are bombs to build, missiles to launch, ...

As for Nepal and the rest of the world:
This earthquake will remain in the global conscience only until it disappears from the broader news agenda. Sooner rather than later, donor efforts will turn to the next disaster. Once interest fades, Nepal will return to the grim realities of everyday life, facing unsafe and underinvested infrastructure, political stalemate, inefficient and dysfunctional institutions, corruption, and ineffective policy. Ideally, this time would be different.
Nope, I am sure by now the world has turned to the latest news: another product of a royal fuck!

Science means never having to say you're sorry :)

A quick follow-up to the Himalayan glaciers controversy.
The IPCC chief formally regrets the error:
Rajendra Pachauri, the head of the panel, told reporters in New Delhi that he regretted including the forecast in the report but said the mistake should not obscure mounting evidence that climate change was a real threat.
"Our procedures are very robust, they are very solid," he said. "All we need to make sure about, is the fact that we adhere to implementing these procedures."
Pachauri brushed aside questions about whether the error would strengthen the hand of climate change sceptics and should prompt him to step down.
"Rational people ... see the larger the picture. They are not going to be distracted by this one error, which of course is regrettable," he said. "I have no intention of resigning from my position."
No word, yet, on whether he has apologized for his labeling of the counter-arguments as "voodoo science" :)

Climate change war heats up over the himalayan glaciers

First the news, and then the reaction.  The news is from the NY Times:
Leaders of the Intergovernmental Panel on Climate Change apologized yesterday for making a "poorly substantiated" claim that Himalayan glaciers could disappear by 2035. .... Experts said the gaffes that came to light in recent weeks don't undermine the IPCC report's main conclusion -- that evidence for global warming is "unequivocal," and human activities are driving the climate shift.
Reaction #1:
IPCC Chairman R K Pachauri on Thursday declined to speak to the media on the Himalayan glacier goof-up issue amid questions being raised about the UN climate body’s credibility in the wake of the controversy.
“I would hold a press conference tomorrow on the issue.
This event is strictly confined to the energy security-related matter,” he said at an event organised by The Energy and Resources Institute (TERI) which is headed by him.
Despite a barrage of questions from the media who insisted that the issue was of global importance and his reaction could clear the air on the matter, Pachauri remained evasive and refused to budge.
“I do not want to speak on the issue (controversy) right now,” maintained Pachauri who had vociferously dismissed a report last year by India’s senior-most glaciologist V K Raina that questioned IPCC’s claim as “voodoo science”.
Reaction #2:
V.K. Raina, the former Deputy Director-General of the Geological Survey of India -- whose research document on the Himalayan glaciers debunked the claims of the Intergovernmental Panel on Climate Change (IPCC) that these glaciers would disappear by 2035 -- is not satisfied by the regret expressed by the United Nations agency.
“I want a personal apology from the IPCC chairperson R.K. Pachauri who had described my research as voodoo science,” Mr. Raina told The Hindu over phone from Panchkula. “Forget IPCC, Dr. Pachauri has not even expressed regret over what he said after my report -- Himalayan Glaciers: a state-of-art review of glacial studies, glacial retreat and climate change -- was released in November last year.”
With over 100 scientific papers and three books to his credit, Mr. Raina said he had not read the Fourth Assessment Report of the IPCC that made the prediction on melting of the Himalayan glaciers, but read the contents only from what was published in newspapers and magazine.
“But all along I knew that this was not based on facts. During my 50 years of research and several expeditions to the region, I never found anything as sensational as was predicted in the IPCC, but no one heard me then.”
It was only after he was asked by the Minister of Environment and Forests to come out with a report that a global debate was initiated on the issue.
So, who you gonna believe? Everyday something exciting, I tell ya :)
