Can a giant ice wall stop Fukushima radiation from leaking into the sea?

The Fukushima ice wall would not look anything like this.

It’s been almost two and a half years since the meltdown at the Fukushima nuclear plant and the place is still a huge, scary mess.

Here’s how The New York Times introduced this week’s grim news from the plant:

First, a rat gnawed through exposed wiring, setting off a scramble to end yet another blackout of vital cooling systems at the Fukushima Daiichi nuclear plant. Then, hastily built pits for a flood of contaminated water sprang leaks themselves. Now, a new rush of radioactive water has breached a barrier built to stop it, allowing heavily contaminated water to spill daily into the Pacific.

It turns out that radioactive water has been spilling into the sea almost since the initial disaster, at a rate of 75,000 gallons, or 300 tons, a day.

So now Tokyo Electric Power Company, or TEPCO, which owns the plant, has a plan to build an underground wall of frozen earth to stop the radioactive water leakage. NPR explains:

[T]o understand, you need to know the geography of Fukushima. There are three melted down reactors, and they’re all right on the coast. To the west, you have mountains. To the east, you have ocean. And so what’s happening is groundwater flows downhill. It flows down through the ruins of the plant and then flows out to the sea. …

So now, TEPCO has proposed literally creating a wall of ice around the plant. And what they’re talking about is not a wall above ground, but freezing the ground around the plant to stop water from flowing in. …

So the basic idea is that they run piping into the ground and they put coolant in the piping and that freezes the earth around the pipes, and it all sort of gradually forms together into a wall. This is something that civil engineers see sometimes, but it’s not that common. And certainly, the way they’re talking about using it in Fukushima is unprecedented. This wall will be nearly a mile around according to TEPCO. It would require more than 2 million cubic feet of soil to be frozen. But if it worked, then it may be the only way to keep water from flowing into the plant and contaminated water from flowing out.

The New York Times points out another challenge: “the wall will need to be consistently cooled using electricity at a plant vulnerable to power failures. The original disaster was brought on by an earthquake and tsunami that knocked out electricity.”

Japanese Prime Minister Shinzo Abe, fed up with continued ineptitude and deception from TEPCO, said this week that his government will get involved in the cleanup. It’s not clear what that involvement will look like, but it may include helping to fund the frozen wall — no small thing, as it’s expected to cost between $300 million and $400 million.

Is Keystone XL a distraction from more important climate fights?

Is Keystone XL a distraction from more important climate fights?

Emma Cassidy

Say what you will about the anti-Keystone movement, but it’s gotten a lot of activists enraged and engaged.

A new article in Nature highlights a supposed rift among some scientists over Keystone XL: Is it a smart focus for climate activists or a distracting sideshow?

There doesn’t seem to be nearly as much of a rift as author Jeff Tollefson suggests, but he does talk to some scientists who are conflicted over the Keystone focus:

The issue has … divided the scientific community. Many climate and energy researchers have lined up with environmentalists to oppose what is by all accounts a dirty source of petroleum: emissions from extracting and burning tar-sands oil in the United States are 14–20% higher than the country’s average oil emissions. But other researchers say that the Keystone controversy is diverting attention from issues that would have much greater impact on greenhouse-gas emissions, such as the use of coal.

Some experts find themselves on both sides. “I’m of two minds,” says David Keith, a Canadian climate scientist who is now at Harvard University in Cambridge, Massachusetts. “The extreme statements — that this is ‘game over’ for the planet — are clearly not intellectually true, but I am completely against Keystone, both as an Albertan and somebody who cares about the climate.” …

For Ken Caldeira, a climate researcher at the Carnegie Institution for Science in Stanford, California, it is a simple question of values. “I don’t believe that whether the pipeline is built or not will have any detectable climate effect,” he says. “The Obama administration needs to signal whether we are going to move toward zero-emission energy systems or whether we are going to move forward with last century’s energy systems.”

In 2012, Andrew Weaver, a climate scientist at the University of Victoria in British Columbia, tried to put the concerns about Canadian tar-sands oil into perspective:

He and a student calculated what would happen to global temperatures if the tar sands were fully developed. The proven reserves — those that could be developed with known technologies — make up roughly 11% of the global total for oil, and Weaver’s model suggested that full development would boost the average global temperature by just 0.03 degrees Celsius. Weaver says that the initial focus should be on coal, which he found would have 30 times the climate impact of oil if the world burned all proven coal reserves.

Still, the fact is that a vibrant climate movement has grown up around the anti-Keystone fight.

Many researchers who have sided with environmentalists on Keystone acknowledge that the decision is mostly symbolic. But in the absence of other action, says Harvard’s Keith, it is important to get people involved and to send industry a message that the world is moving towards cleaner fuels, not dirtier ones.

Says David Victor, a climate-policy expert at the University of California at San Diego, “As a serious strategy for dealing with climate, blocking Keystone is a waste of time. But as a strategy for arousing passion, it is dynamite.”

Our David Roberts made a similar point last year:

There aren’t many easy or obvious ways to make viscerally affecting stories out of the models and statistics of climate science. “Cap-and-trade” certainly stirred no one’s loins. Activists are now looking around for other stories.

In Keystone XL, they found one. Through whatever combination of luck, happenstance, and tenacity, this one worked. It’s an entrée to the climate fight that is immediate enough, vivid enough, to spark the popular imagination. …

From the perspective of activism and social change, such energy and enthusiasm is to be tended like a precious spark.

Does it make sense to critique the Keystone focus and argue for more attention to other aspects of the climate problem? Or should the critics put up or shut up — stop complaining about anti-Keystone activism until they form their own dynamic anti-coal or pro-carbon-pricing movements?

Jamie Henn of 350.org thinks the Nature article gets the frame all wrong:

Seven ways the drought in the West really sucks

Seven ways the drought in the West really sucks

Johnida Dockens

Almost 87 percent of the Western U.S. is in a drought, the Los Angeles Times reports today in a big, gloomy article with big, gloomy pictures. New Mexico is 100 percent droughty. Here are just a few of the ways that sucks.

1. The Rio Grande is so dry that it’s been dubbed the Rio Sand. Satellite photos show reservoirs drying up too.

2. People in parts of New Mexico are having to take drastic measures to get water. “Residents of some towns subsist on trucked-in water,” the L.A. Times reports, “and others are drilling deep wells costing $100,000 or more to sink and still more to operate.”

3. Water wars are flaring up and states are getting litigious. Also from the Times: “Texas has filed suit, arguing that groundwater pumping in New Mexico is reducing Texas’ share of the Rio Grande. Oklahoma has successfully fended off a legal challenge from Texas over water from the Red River.”

4. Wild critters are in trouble. Wildlife managers in New Mexico are bringing water to elk herds so they don’t die of thirst. Some conservationists think those managers should also bring food to bears so the bears don’t lumber into human settlements while desperately seeking sustenance.

5. Trees are taking a beating. Thousands of trees in Albuquerque have died of thirst.

6. Swimming holes are becoming dirt holes. A trio of Texas state agencies is inviting the public to share photos of the drought, and one recurring subject is swimming signs in front of waterless landscapes, like this one.

7. Some desperate farmers in New Mexico have resorted to selling their water to fracking companies so they can afford to pay their bills. As Joe Romm writes at Climate Progress, “The worse news is that many of them are actually pumping the water out of the aquifer to do so. The worst news of all is that once the frackers get through tainting it with their witches’ brew of chemicals, that water often becomes unrecoverable — and then we have the possibility the used fracking water will end up contaminating even more of the groundwater.”

Is climate change to blame for all the droughtiness? The L.A. Times:

The question many here are grappling with is whether the changes are a permanent result of climate change or part of cyclical weather cycle. …

Nonetheless, most long-term plans put together by cattle ranchers, farmers and land managers include the probability that the drought is here to stay.

John Clayshulte, a third-generation rancher and farmer near Las Cruces, removed all his cattle from his federal grazing allotment. “There’s just not any sense putting cows on there. There’s not enough for them to eat,” he said.

“It’s all changed. This used to be shortgrass prairies. We’ve ruined it and it’s never going to come back.”

Cuba is finally embracing solar power

Even Havana might one day get solar power.

Cuba has been slow to catch on to the clean energy trend, but it’s now giving solar a go. The Communist nation’s leaders know they need new energy options “after four failed attempts to strike it rich with deep-water oil drilling and the death of petro-benefactor Hugo Chavez,” the AP reports.

The country’s first solar power plant opened in the spring, and six more are in the works. More from AP:

The solar farm now generates enough electricity to power 780 homes and had saved the equivalent of 145 tons of fossil fuels, or around 1,060 barrels of crude, through the end of July. Peak capacity is expected to hit 2.6 megawatts when the final panels are in place in September.

That’s just a drop in the energy bucket, of course.

Cuba gets about 92,000 barrels of highly subsidized oil per day from Venezuela to meet about half its consumption needs, according to an estimate by University of Texas energy analyst Jorge Pinon.

But hopes are high that solar can be a big winner in Cuba, which enjoys direct sunlight year-round, allowing for consistent high yields of 5 kilowatt-hours per square meter of terrain.

Cuba currently gets just 4 percent of its electricity from renewables, so there’s a lot of room for improvement.

Former Republican EPA chiefs back Obama on climate change

What do Richard Nixon, Ronald Reagan, George Bush, and George W. Bush have in common?

Yes, OK, obviously they were all Republican presidents. But now there’s something else that ties them all together.

EPA administrators who worked for all of those presidents have come out in support of stronger actions on climate change, co-signing a powerful op-ed in The New York Times supporting Barack Obama’s climate plan and arguing that “the United States must move now on substantive steps to curb climate change.”

Here are some highlights from the op-ed, which was written by William D. Ruckelshaus, Lee M. Thomas, William K. Reilly, and Christine Todd Whitman:

The costs of inaction are undeniable. The lines of scientific evidence grow only stronger and more numerous. And the window of time remaining to act is growing smaller: delay could mean that warming becomes “locked in.”

A market-based approach, like a carbon tax, would be the best path to reducing greenhouse-gas emissions, but that is unachievable in the current political gridlock in Washington. Dealing with this political reality, President Obama’s June climate action plan lays out achievable actions that would deliver real progress. He will use his executive powers to require reductions in the amount of carbon dioxide emitted by the nation’s power plants and spur increased investment in clean energy technology, which is inarguably the path we must follow to ensure a strong economy along with a livable climate. …

Rather than argue against his proposals, our leaders in Congress should endorse them and start the overdue debate about what bigger steps are needed and how to achieve them — domestically and internationally. …

We can have both a strong economy and a livable climate. All parties know that we need both. The rest of the discussion is either detail, which we can resolve, or purposeful delay, which we should not tolerate.

Mr. Obama’s plan is just a start. More will be required. But we must continue efforts to reduce the climate-altering pollutants that threaten our planet. The only uncertainty about our warming world is how bad the changes will get, and how soon. What is most clear is that there is no time to waste.

The op-ed also states that there “is no longer any credible scientific debate about the basic facts” of global warming. But, then, nobody should need a bunch of former EPA chiefs to tell them that.

Should we turn deserts into carbon-sucking tree plantations?

Should we turn deserts into carbon-sucking tree plantations?

ACICAFOC

A Barbados nut plantation.

To fight climate change, some scientists think we should vegetate the hell out of deserts. The latest such idea calls for large plantations of a hardy species of Central American tree to be planted in near-coastal desert areas and irrigated with desalinated water.

While forests soak up carbon dioxide, deserts do comparatively little to help with climate change. So should these seas of sand be planted and watered out of existence in a bid to reduce CO2 levels?

Some say yes. The approach would be like geoengineering, but rooted in a more natural system. Scientists call it bioengineering or carbon farming.

The idea of replacing deserts with forests to help the climate is not brand new. A few years ago, for example, scientists proposed planting eucalyptus trees through the Saharan and Australian deserts to help absorb carbon dioxide.

The latest suggested approach, which would involve the planting of vast orchards of Barbados nut trees, technically known as Jatropha curcas trees, was proposed Wednesday by a group of German researchers in the journal Earth System Dynamics. They say vegetating the world’s near-coastal deserts with this species, which can withstand harsh growing conditions, could provide an alternative to mechanical carbon-sequestration techniques.

The researchers crunched some numbers and determined that the carbon-farming costs would be competitive over 20 years with carbon capture and storage, an embryonic technology in which a power plant’s carbon emissions are captured and funneled underground. Carbon farming could be funded by governments through carbon taxes and through the sale of carbon allowances.

“Suitably deployed, these plants could transform unused, barren lands into long-term carbon sinks,” they write in the paper. “The carbon efficiency of this bio-ecosystem would compare favourably with all other existing processes for carbon storage and sequestration, including the cultivation of bio fuels.”

Not only would the trees soak up CO2 and deposit some of it into the soil, but their growth could influence rainfall patterns, soil quality, and regional climates, paving the way for the natural growth of other plants.

Jatropha curcas can withstand conditions that would make most plants wither, but they’re not magical. They still need water. The scientists propose desalinating water from the sea to irrigate the orchards. This is an expensive and energy-intensive way of obtaining fresh water, but the scientists incorporated that into their cost estimates.

Oil from the trees is already used extensively for biofuel, and the scientists say that after an orchard had been growing for a few years it would produce nuts and leaves that could be burned to provide some of the power needed for desalination.

The idea seems worthy of further investigation — although it wouldn’t be much good for the tortoises and other wildlife that revel in the world’s deserts.

Here’s a graphic from the paper that helps explain the proposal:

Koch brothers hire lobbyists to fight carbon tax, save poor and old people

Koch brothers hire lobbyists to fight carbon tax, save poor and old people

Charles and David Koch really, really don’t want a carbon tax.

Carbon-tax proposals are going nowhere in Congress, but the Koch brothers aren’t taking any chances.

A few non-office-holding Republicans and a few actual-office-holding Democrats are calling for a carbon tax, but the current Congress would never pass one, and even the Obama administration has said it doesn’t want one.

Still, a grandstanding Republican representative, Steve Scalise of Louisiana, is pushing a House resolution declaring that “a carbon tax would be detrimental to the United States economy” and “to American families and businesses,” and that it would “fall hardest on the poor, the elderly, and those on fixed incomes.” (Never mind that many carbon-tax proposals are designed specifically to ease burdens on low-income Americans. Facts are not of interest here.)

The billionaire oil-mogul Koch brothers — who’ve convinced many politicians to sign a “No Climate Tax Pledge” — have now hired a gang of lobbyists to push Scalise’s pointless resolution, The Hill reports.

Just how would a tax on carbon pollution hurt American families and businesses? Well, it might take a bite out of the Koch family’s coffers and the Kochs’ businesses.

Still, the Kochs really are concerned about the poor. In fact, Charles Koch is pushing his own plan for lifting people out of poverty; one key component is eliminating the minimum wage.
