Solar power externality and LCOE
I was talking to a very knowledgeable friend about whether solar power will become cheaper than coal in the next decade, and he pointed out a problem in how solar advocates price their power. It's well known that you can't just estimate a solar panel's value based on its peak production capability, because much of the time that panel is producing less power or none at all, doing nothing to amortize costs.
Solar advocates admit this, and use Levelized Cost of Energy calculations to divide energy actually produced by all costs involved, over time and with a discount rate. While solar's over twice as expensive as coal now, the advocates project the cost differential to continue to diminish at the rate it has in the past, and to disappear in a decade.
So my friend's problem is this doesn't distinguish peaking power costs. He's not using the denialist line that baseload power can't include solar at all, but that you still require additional power when solar can't provide it. That additional power is expensive, and this cost externality isn't included in LCOE calculations.
Mulling this over, I think there's an economic and a political angle to take on it. The economic angle is that if we want to consider externalities, then let's by all means consider all externalities - coal isn't going to do so well on that basis.
The political angle isn't whether we should consider externalities, but whether we will consider the externalities and which ones. Greenhouse gas externalities will not be fully priced in for decades, especially for costs imposed on areas outside of the country where the gases are produced (why should we care about those effects?), but they will start to weigh in, a bit, on costs. The brand new mercury rule shows some of the other externalities of fossil fuels will start getting price tags as well. Overall, I think the political process will catch up more quickly on fossil fuel externalities, if still very inadequately, than on on LCOE pricing.
One other point my friend made that was a good one - discount rates for future costs mean few companies care about costs more than a decade ahead. I thought new coal plant starts would be potentially affected by solar price competition, but maybe that price competition is still too far away.
UPDATE: comments point to a good post at Romm's that discusses the various terms and state of play for solar in the US. Ignoring environmental issues for a second to focus on economics, I think LCOE is fine for any buyer to use to determine whether solar prices out well, but the overall system has to consider other price issues as well. The grid parity at the link works when you're buying electricity at the high retail rates, but it will take a lot longer if you're a utility that can buy wholesale.

NIH recognizes chimps can waive rights
The decision by the National Institute of Health to nearly completely eliminate invasive medical experimentation on chimps has received a medium amount of attention. Good news, overall, except the advisory committee had no consensus on testing vaccines on chimps. The testing could accelerate vaccine development but requires infecting chimps with potentially horrible diseases. The lack of a consensus doesn't mean testing should go forward, but leaves a vacuum.

Glenn Greenwald is primarily responsible for the failure of progressive legislation since 2008.
The reasoning's simple: Greenwald's part of the left, just like Obama and the Democrats who controlled the House and had a filibuster-proof majority in the Senate for a while. Greenwald's side failed to pass enough progressive legislation, therefore Greenwald's primarily responsible.

Obama good, Obama ungood
The good news is decision that gay rights and human rights "are one and the same" in a speech by Hillary Clinton, one that states the Obama administration will work for this concept internationally, and put some money behind it. They also acknowledge imperfections here in American, while being studiously silent on gay marriage.
UPDATE: Chris Mooney on Plan B here. Similar grasp of the obvious.

The Water District reducing GHG emissions and California cap-and-trade
Today's Water District meeting featured an energy usage work study session. We use a lot of energy moving water across much of the state and then treating it, about 5% of all our costs. While we also have a policy saying we that want to reduce greenhouse gas emissions, our policy isn't very clear. I pressed staff on this issue and another director, Linda Lezotte, also followed up:
(Arrgh, something won't let me post more than one video excerpt. It's here for the December 5 2011 meeting at the 01:11:00 mark, for about 4 minutes. Two of us seven directors say we need to do more than merely "cost-effective" efforts to reduce GHG emissions, the other five don't say anything.)
We're pretty good overall in our energy usage. Maybe we can partner with Sonoma County to be better.
We're part of a joint powers authority for buying our power at a rate that's both cheaper and with lower carbon emissions than our local utility provides. Our CO2 emissions are 435lbs/MWh, one-third the national average (see the first link, Attachment 4, p 17). Not the one-tenth that we need, but pretty good.
While California cap-and-trade doesn't apply directly to us, it does apply to the joint powers authority called PWRPA that we helped establish to get our power, and we may have a chance to sell carbon allowances from environmental improvements that we make:
(UPDATE: okay, more linkrot, but it's towards the end of the discussion of Item 4.1 at the link above.)
In addition to what you can see on the video is the 3 hours that we spent in closed (confidential) session to discuss internally the negotiations with labor unions for new contracts. Obviously I can't talk about what happened then, but the financial issues highlight how important the economics of all this is. If doing the right thing environmentally can help us out financially, we're going to do more of the right thing, especially right now when finances are so tight.

Crowd-sourced screening of abusive/misogynist comments for women bloggers
I've been reading more in the past few weeks about the type of garbage that women bloggers have to put up with, stuff I've never experienced. A recent comparison:
As the New Statesmanblogger David Allen Green told me: "In three years of blogging and tweeting about highly controversial political topics, I have never once had any of the gender-based abuse that, say, Cath Elliott, Penny Red or Ellie Gellard routinely receive."One way to discourage this is for women bloggers to moderate and screen comments so the abusive ones never get printed. This adds to the blogger's work load, though (and may not be possible at some work blogs), and more importantly, the anonymous abuser still gets away with exposing the blogger to abuse that ranges from mean-spirited to threats of rape.
The idea I'm suggesting is that for the bloggers who want to do so, they should be able to outsource comment screening to third-party volunteers who will kill the abusive comments (or alternatively, set them aside for later review by the blogger if she wants to check, or alert her if comments go beyond misogyny and make actual threats). This would deprive the morons of their ability to directly insult the women they're targeting. I suppose they could try and threaten us reviewers, but they wouldn't even know who we are or what our gender is, so have fun with that.
I don't think it would be too hard to crowdsource the screening: you're reading for abuse, not trying to handle the content, so it would be a pretty quick and easy thing to do. A confidence rating system like Ebay uses could help bloggers decide if they trust the reviewers. We'd need some special software so comments could be redirected in this manner, but I can't imagine it would be that difficult. An enterprising blogging platform could even attach some discrete advertising to make the project pay for itself.
Just an idea I'll thow out there. I'd even put some effort into it if someone wanted to make it happen.
(Probably should re-emphasize that the best solution is for the particular men making the comments, to stop. This is a second-best solution, and only for the bloggers who'd want to make use of it.)

Climate related comments elsewhere
At Same Facts, James Wimberley continues to do a good job IMHO of defending the "solar on track to be cheaper than coal" idea. I wrote:
What I’d be most interested in knowing is the rate of starts for new coal power plants, especially in countries with no local coal supplies (therefore no coal lobby). A new plant takes a couple years to build and 30-50 years to pay off, so [Efficient Market Hypothesis] (if accurate) would expect to see a significant dropoff for these.
At Nature, on a post about whether mastodons got stuck in post-earthquake mud and starved over a period of months, I skepticized:
I follow climate change denialism closely, so I'm very suspicious when non-experts proclaim themselves to be personally incredulous regarding a conclusion by experts.
That said, as a non-expert, I am personally incredulous that partially submerged mammoths couldn't pull themselves out of the soil when liquefaction had ended.
Tar pits I can believe. Full submersion and immediate suffocation I can believe. But being stuck in one spot and slowly starving to death without being able to pull their legs out of the soil, is something that needs to be a little more convincing. Maybe they need to a mechanical analysis of soil strength and compare it to an elephant's strength.
Sure felt like an article I would read on April Fool's Day, but what do I know. (UPDATE: the teeming hordes of pro-stuck-mammoth factionalists attack in the comments, all two of them, and I guess they have a point.)
Finally, not a comment but a link to an interesting NY Times article on growing crops underneath trees. No mention of albedo issues from trees being darker than typical ag, though.

My review of George R. R. Martin's Song of Ice and Fire: epic meh
So I can't exactly pan his books seeing as I've read the entire A Song of Ice and Fire series in less than three months, but if I could go back in time I'd warn myself, don't do it. Or maybe just read the first book, which is the best, and then watch the HBO Game of Thrones show as it gradually recapitulates the books (disclaimer: haven't seen it, but it gets great reviews).
UPDATE: I half-expected to either get flamed or ignored, but apparently the rabbits agree that Martin's overrated. They provide alternatives.

Peiser relies on deception
Benny Peiser, sadly, appears to be on the upswing in climate change denialism (and possibly wrong elsewhere, although I don't know the Easter Island issues well). My experience with him is that he made an incorrect factual assertion, stopped making it when caught by a knowledgeable audience, and then repeated the original assertion in front of different audiences that didn't know the truth and didn't know about his retraction. This is the person being quoted by news media today.

To fluoridate, someday, and a personal announcement
Santa Clara Valley Water District OKs adding fluoride to its drinking water
Silicon Valley's largest drinking water provider took the first steps Tuesday toward adding fluoride to the drinking water in most of Santa Clara County, including San Jose, the largest city in the nation without the cavity-battling additive.After a lively 90-minute debate at a packed meeting, the board of the Santa Clara Valley Water District voted 7-0 to put the district on record supporting fluoridation.

To fluoridate or not to fluoridate, that is the question. Next Tuesday at my Water District Board meeting
I'll reproduce below most of an old post about fluoridation. I had previously expected to see an identical situation with climate change in terms of the debate, but it's not. I think factors overall favor fluoridating, but not quite as overwhelmingly as I expected. On Tuesday, my fellow Directors and I get to figure out next steps.
Fluoridating water, or a funny thing happened on my way to backseat driving
I originally labelled this blog Backseat Driving back in 2004 because I anticipated it to be a blog where I would second-guess decisions made by politicians and other people. That worked out fine more or less until November 2010, when for some reason I was elected to the Santa Clara Valley Water District Board. Turns out that San Jose is the largest city in the US without fluoridated water supplies (in much of the city, anyway), and the seven of us directors have to decide whether we'll help or hinder the fluoridation process. So I'm pushed into the front seat for this one.
We've got some legal and economic issues to handle (it's not quite as cheap as everyone says, I want to know where the money's going to come from), but the relevant issue here is science. I read the guest post at climate blogger Coby Beck's place, The Case Against Fluoride, fairly closely a while back, especially the raucous debate in the comments. As a spectator with some, limited reading of the available information, I'd say the fluoridators seemed more persuasive than skeptics, but it wasn't the absolute demolishing that I expected.The fluoride skeptics really hurt their cause when say fluoride doesn't prevent cavities - it's so obviously effective that people making this claim are damaging their own credibility. I'd consider it comparable to denying that the planet has warmed in the last 50 years.
The closer issue is adverse effects, and whether a substantial number of people are very slightly harmed by fluoridation, or if a small number of people are substantially harmed. The 2006 National of Sciences report doesn't condemn fluoridation, but it doesn't absolve it, either:
Bone Fractures
....Overall, there was consensus among the committee that there is scientific evidence that under certain conditions fluoride can weaken bone and increase the risk of fractures. The majority of the committee concluded that lifetime exposure to fluoride at drinking-water concentrations of 4 mg/L or higher is likely to increase fracture rates in the population, compared with exposure to 1 mg/L, particularly in some demographic subgroups that are prone to accumulate fluoride into their bones (e.g., people with renal disease)....There were few studies to assess fracture risk in populations exposed to fluoride at 2 mg/L in drinking water. The best available study, from Finland, suggested an increased rate of hip fracture in populations exposed to fluoride at concentrations above 1.5 mg/L. However, this study alone is not sufficient to judge fracture risk for people exposed to fluoride at 2 mg/L. Thus, no conclusions could be drawn about fracture risk or safety at 2 mg/L....(In California, 2 mg/L was the limit, and 0.7 is the new proposed goal. -Ed)
Neurotoxicity and Neurobehavioral Effects
Animal and human studies of fluoride have been published reporting adverse cognitive and behavioral effects. A few epidemiologic studies of Chinese populations have reported IQ deficits in children exposed to fluoride at 2.5 to 4 mg/L in drinking water. Although the studies lacked sufficient detail for the committee to fully assess their quality and relevance to U.S. populations, the consistency of the results appears significant enough to warrant additional research on the effects of fluoride on intelligence....Endocrine Effects
The chief endocrine effects of fluoride exposures in experimental animals and in humans include decreased thyroid function, increased calcitonin activity, increased parathyroid hormone activity, secondary hyperparathyroidism, impaired glucose tolerance, and possible effects on timing of sexual maturity. Some of these effects are associated with fluoride intake that is achievable at fluoride concentrations in drinking water of 4 mg/L or less, especially for young children or for individuals with high water intake. Many of the effects could be considered subclinical effects, meaning that they are not adverse health effects. However, recent work on borderline hormonal imbalances and endocrine-disrupting chemicals indicated that adverse health effects, or increased risks for developing adverse effects, might be associated with seemingly mild imbalances or perturbations in hormone concentrations. Further research is needed to explore these possibilities....(Removed discussion of bone cancer as not very troubling given its rarity. Ed.)
These were the most troubling findings, mostly about what hasn't been proven, and mostly dealing with levels that are five times what's planned for drinking water. The report expressly ignored the benefits of fluoridation. It's important to balance out potential concerns over rare, severe complications related to fluoride with the certainty that rare, severe complications can result from cavities.The bottom line as a policy maker in my little arena is that I shouldn't try and figure out the science myself, but I should try to figure out what the scientific consensus is, figure out where the consensus doesn't yet exist, and then plug that information into everything else we have to balance.The science seems to favor fluoridation, but it's not a slam dunk. And we still have potential policy barriers, and the overall cost issues. Figuring this all out will be interesting.

Tidal wetland sediment accretion might keep up with sea level rise in one location. Maybe.
I attended our annual Santa Clara County Creeks Conference last Saturday, with an even better than usual program that included a panel on tidal wetlands restoration in South San Francisco Bay, where we're bringing back 16,000 acres of tidal wetlands from former saltponds (will post a video link when it's online).

Ideal human population is 100 billion. Off-planet.
My off planet assumptions are for 200-300 years; that the Moon, asteroids, and free-floating colonies have been settled with lots of people; that Martian life discovery protects Mars from colonization; and that Venus hasn't yet been terraformed. And that there's no Singularity - otherwise all bets are off.* There's lots of room out there in space, and changing some of these assumptions make mine a low-end figure.

A scientist is a feather, a lawyer is a sail
Some time ago I guest-lectured to some undergrads in a science curriculum track about environmental advocacy. I said I had read somewhere that a scientist is a feather and the evidence is the wind - the scientist makes no effort to control the evidence but just floats wherever it takes her. Obviously this is an incomplete construct that ignores hypothesis formation etc., but is supposed to represent the ideal of how a scientist reacts to evidence.

China follows up India in committing to being better than US on per-capita emissions
As has been covered in a few places, China has committed not to "follow the path of the US" with its current level of per capita emissions. (I agree with Joe Romm, btw, that they're not otherwise likely to hit the US level by 2017. They were at one-third the US level three years ago, and it can't go up that fast.)

Occupy Wall Street, and I have one-seventh of the vote over several hundred million dollars
My light-speed brain took over a month to put the two issues in the blog headline together. Santa Clara Valley Water District has several hundred million dollars in financial reserves. I wonder if there's anything financially responsible that the Water District can do with the voters' financial reserves, in light of the abuse of the financial system by Wall Street titans.

My weeklong life as a Washington water lobbyist
- I can confirm the obvious statement that the budget process is broken. I respect the antipathy to earmarks and am open to replacing them with another process, but what we have instead is virtually no process to provide local input into federal decision-making about local projects. We had multiple meetings with Congressional offices where they often said they could do little to help, and just one with the Office of Management and Budget, which now has all the power.
- There is real interest in the Obama Administration in the environment. We talked about environmental benefits to one relatively high-level official in the Department of Agriculture who'd been hired from an environmental organization. She raised Obama's Great Outdoorsinitiative that tries to reconnect Americans to our natural environment, including urban areas. So I pointed to a map that we brought. Here in south San Jose, wild elk will sometimes roam within city limits. In north San Jose where San Francisco Bay ends,leopard sharks swim. Connecting them is Coyote Creek, a major intact riparian system running through central San Jose with migrating, endangered steelhead, a bike/pedestrian pathway, great views of hawk nests. Our flood control project is a major tributary where we want to rip out concrete, replace it with vegetated-earth banks, and add riparian habitat next to an elementary school. She liked it.
- We can at least take some actions to adapt to climate change. We're trying to restore 15,000 acres of abandoned salt-making ponds to tidal wetlands, but the pond levees form part of the antiquated levee system protecting urban land in the South Bay. We want to rebuild and strengthen the landward side of the multi-ring levee system, and only then can we breach the bayside of the salt pond levees and restore them to tidal flow and vegetation. This was our one meeting with OMB, and there I emphasized that we're sizing the levees to accommodate 50 years of sea level rise (based on Cal. Academy of Sciences 2006 report, using the high end of three scenarios), and sized so they can be built up higher if needed. The OMB people seemed interested, so we'll see.

The most perceptive pro-Palin comment ever written
Supporters of Palin say they're not using "rational theorizing"
What's especially interesting is the enthusiastic response following this idea of "going with your gut and calling it wisdom". I think the truth is a lot of what all of us consider reasoned analysis that reaches a conclusion is actually a gut response that's going through the motions, but to not even bother to fight for logic and knowledge is pretty striking.I think Sarah Palin is indeed a Rorschach test for Conservatives...it’s about what Conservativsm MEANS....
The core idea behind Conservatism is that most of human learning is done not by rational theorizing, but by pattern recognition....
This pattern recognition is called common sense, and over generations, it’s called traditions, conventions etc. Religion is usually a carrier meme for these evolved patterns. It’s sort of an evolutionary process, like a genetic algorithm....
Liberals, Lefties and even many Libertarians want to use only 10% of the human knowledge that’s rational.....
Conservatives are practical people who instinctively recognize the importance of evolved patterns in human learning: because our rational knowledge simply isn’t enough yet, these common sense patterns are our second best option to use. And to use these patterns effectively you don’t particularly have to be very smart i.e. very rational. You have to be _wise_ and you have to have a good character: you have to set hubris and pride aside and be able to accept traditions you don’t fully understand....
Anti-Palin Conservatives don’t understand it. They think Conservativism is about having different theories than the Left, they don’t understand that it’s that theories and rational knowledge isn’t so important.
