But is it new (extremely alarming as a possible sign of climate change), impossible to know how long it’s been going on (still worrying), or might it have been happening for a long time (less alarming)? Even the scientists involved seem unsure. 

In the worst case, the leaks are recent and caused by global warming — a thaw of the seabed permafrost linked to rising sea temperatures that could go on to release vast buried stores of the heat-trapping gas that would further stoke global warming. In the best case, it may have been going on for thousands of years in an inaccessible area where no one has taken measurements before.

Either way, it’s worrying because a projected rise in temperatures could further erode the permafrost that had previously been considered an impermeable cap and so lead to more releases of methane.

The article in the journal Science  makes clear that you can’t tell whether it’s new or not –more monitoring is urgently needed. 

The University of Alaska, where some of the scientists are based, put out two embargoed press releases. The original said the seabed is “starting to leak” (very alarming)

The second one, which replaced the first about a day before the embargo was lifted, changed the second paragraph to drop the word “starting” and merely say the seabed “is leaking” (worrying):

So let’s hope it’s been going on for ages.

-Bernd Debusmann is a Reuters columnist. The opinions expressed are his own-

The project involved more than 2,500 scientists. It cost $ 10.5 billion between 1983 and 2009 and it included one of the most bizarre scientific tasks of all time: evaluate whether nuclear waste stored deep inside a Nevada desert mountain would be safe a million years into the future.

That was the safety standard set in September, 2008, by the Environmental Protection Agency (EPA) as a condition for allowing nuclear waste to be stored deep in the belly of the Yucca Mountain, 95 miles (155 km) from Las Vegas, long the subject of political debate and a fine example of nimbyism (not in my backyard).

The vastly complex computer models and simulations experts launched to figure out whether Yucca Mountain would be a safe environment in the year 1,000,000 and beyond ended before there was a scientific conclusion.

President Barack Obama has pulled the plug on the entire Yucca Mountain enterprise, million-year safety study and all, by writing it out of his financial year 2011 budget, which begins in October.

Yucca Mountain’s death by budgetary axe defies logic. It coincides with Obama’s stated support for expanding nuclear power. More reactors mean more waste, now piling up above-ground at sites scattered around the country.

In February, Obama announced $8.3 billion in government loan guarantees for two nuclear reactors in Georgia. They would be the first new plants since the 1979 nuclear meltdown at Three Mile Island in Pennsylvania, an accident that caused no casualties but became a rallying symbol for the anti-nuclear movement.

Citizens Against Government Waste, a Washington watchdog group, described abandoning Yucca Mountain without figuring out what to do, long-term, with the toxic nuclear waste produced by new (and existing) reactors as “patently illogical,” a “politicized and short-sighted decision.”

The group is right.

This is a matter of politics trumping science and it involves a president who pledged, in his inaugural address, to “restore science to its rightful place” from where, in the eyes of many Obama partisans, it had been dislodged by the administration of George W. Bush, routinely accused (and often with good reason) of “politicizing science.”

Yucca Mountain, which rises 4,950 feet (1,510 metres) from the Mojave desert, on the edge of a nuclear test site, was meant to be the central burying ground for radioactive waste now stored at 121 sites in 39 states, some 150 million pounds (68 million kg) of toxic stuff and more piling up. The material is initially submerged in pools of water and then sealed in steel and concrete casks.

The idea of shipping them all to a remote site in the desert has had wide appeal - except for most people in Nevada, where Senator Harry Reid, now the leader of the Democratic majority in the Senate, has been waging a relentless campaign against using Yucca.

“I am proud that after two decades of fighting the proposed Yucca Mountain nuclear waste dump, the project is finally being terminated,” Reid writes on his website. “(It) is simply not a safe or secure site to store nuclear waste.”

That’s his opinion. There’s no shortage of scientists who disagree.

AN INSULT TO INTELLIGENCE?

During Nevada stops in his campaign for the presidency, Obama came out strongly against Yucca Mountain, a position that helped him beat his Republican rival John McCain and win the hotly-contested state’s five electoral votes.

McCain has called closing the mountain while encouraging new plants “an insult to intelligence.”

Reid is running for re-election in November and he will no doubt hold up the decision on Yucca Mountain as a triumph of his persistence. His poll numbers have not been good recently and it remains to be seen whether Yucca will lift them. Some Republicans are convinced that Obama’s nuclear waste decision was taken purely for the benefit of Reid.

In an op-ed in the Washington Times late in February, Mark Sanford, the Republican governor of South Carolina, home to a nuclear complex holding 36 million gallons of liquid radioactive waste, said that the Obama administration was “walking away from a $10 billion investment and starting all over because of one man’s race for office in Nevada.”
Starting all over?

That process is meant to be initiated by a 15-member Blue Ribbon Commission, a device not infrequently used in Washington to give the appearance of action while actually delaying it. As Citizens Against Government Waste put it: “The administration is kicking the nuclear can down the road, into the next administration and onto the shoulders of future taxpayers.”

The commission, heavy on Washington insiders and relatively light on scientists, has two years “to provide recommendations for developing a safe, long-term solution to managing the nation’s used nuclear fuel and nuclear waste.” Looking for an alternative site to Yucca Mountain, another deep-underground storage facility, apparently is not part of the commission’s brief.

So then what? Start from scratch? Perhaps a return to the dawn of the nuclear age? The options under discussion then included burying radioactive material in the ocean floor, placing it in polar ice sheets — and even blasting it into space.

This year a group of filmmakers in newly modernised, consumption-happy Taiwan is going to the densely populated western Pacific island’s public with an hour-long alarmist movie showing the world’s second-tallest building Taipei 101 as an island in a flood that has drowned the capital after a reservoir collapses in a freak super-strength typhoon.

The free film with an obvious mission titled “Plus or Minus 2 Degrees Celsius” began showing in late February, reaching at least 11,000 people so far and with dates to screen for more audiences later in the year.

 It also shows footage from snowstorms, droughts and other real natural disasters around Asia to rub in its point, which has set off critical debate among Taiwan academics.

“A lot of people know about climate change but don’t understand what its impact would be,” said Lu Yu-rou, media specialist with film promoter the Taipei-based Plus or Minus 2 Degrees Campaign Alliance. And after watching the film? “A lot of people actually think it’s pretty shocking. They never expected that such as severe situation could develop.”

Asher Miller is executive director of think tank Post Carbon Institute. Any opinion expressed here is his own.

It should come as no surprise to anyone paying attention to the politics of climate legislation to hear Senator Lindsey Graham pronounce, “the cap-and-trade bills in the House and Senate are dead.” The truth is that they’ve been dead for quite some time. It’s just that now we finally have the coroner’s official report.

Many proponents and opponents of climate legislation have had one thing in common for some time now—they hate the American Clean Energy and Security Act (the Waxman-Markey bill which passed in the House by a narrow margin back in June).

So an unlikely assembly of hardcore climate activists and equally hardcore climate deniers likely greeted Graham’s announcement with some measure of satisfaction.

The opponents’ argument against the bill is stunningly simple: They don’t believe in human-caused climate change.

The arguments on the other side are, not surprisingly, more numerous and more complex, not to mention more valid. The reason why so many climate activists like myself have opposed ACES is that the 1,400-page House bill was riddled with so many giveaways to polluters, and set targets so low and so slow, that folks were honestly debating whether or not it would be better to have no legislation at all than this piece of… paper.

Keep in mind: with a much narrower majority in the Senate, the bill was likely going to get watered down even further.

So is Graham’s pronouncement good news? Yes, and for two reasons:

First, at least Senator Graham is being honest. This is an election year and the healthcare debate is now going into extra innings. How likely is it that the Obama Administration and Congressional Democrats are up for a doubleheader, when game two is far less of a guaranteed win in terms of public support than game one was supposed to be?

Lack of progress in Copenhagen and doubts sewn by coordinated campaigns to discredit climate science only serve to make the outcome of any debate on Capitol Hill all the more uncertain.

It’s no surprise, then, that Congressional leaders are looking for new approaches. And that’s a good thing.

Which gets to the second point: If this is indeed a new ballgame, Senator Graham’s pronouncement could actually open the way for more meaningful legislation.

Graham is busily crafting a new bill with Senators John Kerry and Joseph Lieberman. Who knows what it will actually contain? But there is already another alternative out there that could be a clear (pardon the pun) game changer.

In the months since ACES stalled, slow but steady momentum has built for an alternative approach called cap and dividend. In late 2009, two Senators, Maria Cantwell and Susan Collins—from opposite ends of the country and opposite sides of the aisle—introduced the Carbon Limits and Energy for America’s Renewal (CLEAR) Act.

In contrast to ACES, wherein a large number of permits would be given away to polluters, CLEAR would auction off 100 percent of the carbon permits. And rather than create a complex market for trading these permits, CLEAR would send 75 percent of revenues to the American people in the form of monthly checks (the other 25 percent would be invested in clean energy, energy efficiency, and conservation programs). That’s right—actual checks that Americans can put in their savings accounts or use as they see fit. And it’s not like this is a new idea or would bankrupt the energy industry. Just ask Alaskans how they like their Permanent Fund, which has been sending them checks since 1976.

In this economic climate, cap and dividend makes a lot more political sense than cap and trade (cue images of Wall St. fat cats getting fatter) or a carbon tax, however more substantive the latter may be.

Which is why cap and dividend could actually work if positioned right. Positioned as a climate bill, it will fail. Positioned as a means of putting money in every American taxpayer’s pocket while reducing our dependence on foreign oil and creating jobs, it may just succeed.

Here’s hoping it does. The stakes of this game couldn’t be higher.

This article by Beth Hodgson originally appeared in GlobalPost.

Over the last few months, we’ve seen serious discussions taking place globally as countries and cities pledge to go green.

Some cities have made greener strides than others, which puts them at the top of the list for sustainability goals.

The five greenest cities in the world aren’t necessarily those that are nothing but green space, but they’re on the right track to improving their footprints.

5. Vancouver, Canada

Vancouver has been recognized for trying to make the Winter Olympic games sustainable, but it’s their day-to-day focus that really allows this Canadian city to earn its ranking. Ninety percent of Vancouver is powered by hydroelectricity.

Wind, solar, wave and tidal energy all help ensure that this city remains green. Plus, they’ve got even greater goals for the future.

4. Malmo, Sweden

This is one international city that is focused on green space. They are well-known for their parks, but also upon sustainable urban develop. It’s one of the largest cities in Sweden and it’s truly urban. They’ve been transforming neighborhoods to make them environmentally friendly.

3. Curitiba, Brazil

This Brazilian city focuses upon maintenance using green methods, for example, parks that are trimmed by sheep. They are also known for one of the best transit systems, so commuters are encouraged to leave their cars at home.

2. Portland, Oregon, United States

Although many U.S. cities are now jumping on board, this was the first to focus upon alternative transit with light-rail and extensive bike path networks to encourage people to leave their cars in the driveway! It was also one of the first to pledge to reduce emissions and start transitioning buildings to use sustainable materials.

1. Reykjavik, Iceland

This city is run entirely on green power, including geothermal and hydroelectricity. Their transit system also uses hydrogen buses and it’s motivated to become Europe’s cleanest city.

Among their denunciations of widely-accepted truths regarding global warming, greenhouse gases, melting glaciers and rising sea levels was the assertion that a change in attitude was afoot; the public may have been duped into believing the mainstream scientific assessment of climate change, but not for long.

There was something in the air, the sceptics said, and soon people would begin to question their trust in the majority view.

I’m no scientist and am in no position to comment on the validity of any of the evidence on show; as journalists we were there to make sure both sides of the argument were being heard. This group of climate outcasts were in every sense on the fringes of COP15, but after a series of controversies in recent weeks it seems they were right about one thing at least — the public conviction about the threat of climate change is slipping.

Well, it is in Britain anyway. An Ipsos Mori poll of over 1,000 UK adults found that the proportion of people who believe climate change is definitely a reality dropped from 44% to 31% in the past year.

Meanwhile, 31% said the threat was exaggerated, up 50% on last year – worrying statistics for the government and charities trying to convince the public to change its behaviour and to accept higher priced energy and goods as a small price to pay for saving the planet.

Why the sudden drop off? The poll follows weeks of suggestions that mainstream climatologists have, in the past, manipulated data and that an influential study by the U.N.’s main climate science body contains inaccurate information.

The arguments of sceptics were fuelled late last year by the incident dubbed “Climategate”, when hundreds of emails and documents passed between leading climate scientists were leaked online. The deniers claimed this was evidence that some climatologists were colluding to distort data and mislead the public on climate change.

Elsewhere, the Intergovernmental Panel on Climate Change (IPCC) admitted its claim that Himalayan glaciers  could melt by 2035 was unsubstantiated. The U.N. has since announced it is setting up an independent board of scientists to review the IPCC’s performance.

Meanwhile a 2009 report which claimed sea levels would rise by as much as 82 centimetres by the end of the century has been withdrawn by its author, who now says the true estimate is in fact unknown. At the sceptics conference in Copenhagen I spoke to Nils-Axel Mörner, an expert in sea levels, who questioned the general conception that sea levels are rising — in the video clip below he explains why, in his opinion, they are in fact falling.

And, of course, the failure of world leaders at COP15 to agree a successor to the Kyoto Protocol didn’t help matters either.

If this trend continues, the climatologists, politicians and activists who subscribe to the mainstream view may find that the real challenge now isn’t getting the public to change their behaviour, it’s getting them to trust their evidence.

Has your faith in mainstream climate science been knocked by recent controversies? In your view, how much of a threat is global warming?

John Laforet is president of Wind Concerns Ontario, a coalition of 42 grassroots organizations aiming to curtail development of wind farms in the central Canadian province of Ontario.  He is also running for municipal public office.

Governments around the world are actively seeking private development of renewable energy projects by offering generous feed-in tariffs that often see developers paid many times the market rate for the power they produce.

This has encouraged a surge of applications, but the volume of applications and other challenges associated with these projects present potential risks to prospective investors.

Projects require transmission capacity to carry their energy to market, but the agencies accepting applications for a given jurisdiction often aren’t responsible for managing transmission systems.

In the Czech Republic, a boom of renewable projects has caused considerable challenges to the transmission system and has caused the grid operator to block future wind projects, while threatening to disrupt grid connections for existing renewable energy projects.

In Canada, Ontario’s inventory of projects under development, approved or in the proposal stage, does not consider existing grid capacity.

While individual proponents compete for feed-in-tariff agreements without guaranteed access to grid capacity, a multi-billion dollar investment by the government into the grid would be required to facilitate many of these projects getting off the ground.

In a time of plunging tax revenues and mounting deficits, and growing community opposition to these projects, this creates instability for investors.

Weak regulations designed to streamline approval processes and silence community opposition have resulted in legal action against proponents worldwide.

Developers are being sued in many jurisdictions, and in at least two notable examples, either lost in court or settled for millions of dollars.

A French court ordered the turbines in Cast and Châteaulin to be turned off between 10pm and 7am, thereby generating zero revenue or electricity during that time.

In Ontario, Canadian Hydro Developers settled a number of legal actions at a cost of $1.75 million as a result of individuals who complained of negative health effects. These include Barbara Ashbee-Lormand who says she and her husband found it intolerable to live in their home in Amaranth, a rural township that is host to 22 industrial wind turbines.

A growing number of American municipalities have banned the installation of industrial wind turbines in response to community opposition, including in North Carolina, and Liberty, Illinois.

Offshore, lake-based proposals in Ontario have faced two moratoriums in three years, and projects in Australia have seen endangered species legislation used to halt approvals.

While a feed-in tariff agreement may make investments in renewable energy look attractive, the lack of control project investors have over their ability to reach the market should give investors pause.

With potential for liability for negative health impacts, lawsuits from communities and growing interest from the courts, in addition to other instability built into the approval process, this is one “green” sector that could quickly turn red, at least for investors.

The blogosphere is rumbling with anticipation of the  “Bloom Box”, a pint-sized “power plant” that could change the way we power our homes and offices forever.

The buzz began Sunday when 60 minutes aired an exclusive profile of the alternative energy fuel cell developed by startup Bloom Energy and its CEO K.R. Sridhar (a former rocket scientist) in Silicon Valley. After eight years in the making, the power plant in a box is set to be released Wednesday with California governor Arnold Schwarzenegger and former Joint Chiefs of Staff chairman Colin Powell on hand.

“You’ll generate your own electricity with the box and it’ll be wireless. The idea is to one day replace the big power plants and transmission line grid, the way the laptop moved in on the desktop and cell phones supplanted landlines,” reports CNet News.

What makes this claim to the perfect, zero-emission energy source different? For starters, backing from Walmart, eBay, Google, Staples, FedEx, and hundreds of millions of dollars in investments.

And, the World Economic Forum names Bloom Energy as one of 26 top 2010 Technology Pioneers: Energy and Environment.

But the Bloom Box isn’t cheap. The Daily Tech reports: “Well, $700,000 to $800,000 will buy you a ‘corporate sized’ unit… To get a view of the cost and benefits, eBay installed 5 of the boxes nine months ago. It says it has saved $100,000 USD on energy since.”

The hype is not new. Since at least 2006, tech industry watchers have kept an eye on Bloom — which has been working on the fuel cell box for more than 8 years.

60 Minutes also ran this Skeptic’s video.

Predominantly, Islamic finance and investment products have been backed by infrastructure or commodities assets. But executives at the 2010 Reuters Islamic Banking and Finance Summit said product diversification was needed to cut the over-reliance on real estate in the Gulf.

“Sharia scholars are eager to support the renewable energy initiative, but the Islamic banking industry (in the Gulf) does not seem to be overly interested in this area although I am aware of a couple of deals involving acquisitions of clean tech companies in the U.S. and wind farms in the UK,” said Ayman Khaleq, partner at the Vinson & Elkins law firm in Dubai.

“The big banks have teams that focus on renewable energy as an asset class. However, the problem is that Islamic banks are not big enough to be able to cover specific sectors such as alternative energy,” he added.

In order to launch an alternative energy sukuk, the Gulf’s small local banks would need to team up with bigger international players such as Deutsche Bank, Barclays, or BNP Paribas, which have been active on the renewable horizon.

But some experts have warned more originality in the Islamic finance industry could alienate investors, who are reluctant to take on fresh risk in the wake of Dubai’s debt crisis and recent sukuk defaults in the region.

WAITING FOR THE GREEN PUSH

Despite favourable environmental conditions in the Gulf offering fertile ground for green technologies, Abu Dhabi’s Masdar initiative is so far the region’s only flagship initiative. www.masdar.ae

“Although in the Gulf, with the sun and desert, you would think that solar energy would be worth harnessing Islamically or otherwise,” Khaleq said.

Gulf states are in need of economic diversification as the oil bonanza is slowly drying out, and are urged to develop alternative energy sources.

An industry source said sovereign wealth funds from Bahrain or Malaysia, and family offices in Saudi Arabia or Kuwait, could nevertheless become potential investors.

“There might be venture capital type of funds that could look at these new technologies in the Gulf,” the source added.

Khaleq is optimistic an alternative energy sukuk could see daylight soon: “I’m hoping in 2010, but Islamic investor, and generally regional investors, are being more conservative and so are the scholars,” he said.

“However, the ingredients are there: structures, acceptability of asset class, interest and technology. But it is a question of who will be the pioneer in making it all happen.”
