Larger warming over land than over ocean leads to - larger PE increases over land than over ocean - increases in water vapor transport from oceans can not match atmospheric demand over land -> drier conditions over land.
This is a suggestion I made earlier - but in email I had with him at the beginning of 2012 he didn't confirm it - so I'm happy to see him do so here.

This graph was also particularly interesting - suggesting that recent improvements to latest climate models (CMIP5 vs CMIP3) haven't changed the answer much:

And:
The current dry conditions in the U.S. may last and worsen during the next 20 yrs as the IPO cold phase persists and global warming continues.

Off Topic Worthy Cause: American Co-operative School in Tunis

A friend of my family is the principal at the high school in the American Co-operative School in Tunis - which was recently looted and badly damaged in an attack by Islamic radicals and delinquents.  They have now launched a recovery fund to help them rebuild.  I think it would be good for American society to show a peaceful determination not to back down in the face of that kind of violent intimidation and to rebuild the school.  The staff are displaying a great deal of personal courage in sticking with the school and rebuilding it after what has happened.  I encourage my readers to both donate and share the link with others: www.acst.net.

Politics and this Blog

It probably hasn't escaped the attention of readers that my politics are a little left of center - with the typical meanings of "left" and "center" in current US politics.  This "leftiness" is greater on some issues (environment, social issues, civil rights), and much less so on others (education, wealth redistribution).  I have at various points been registered either Democrat or Independent.

So far, on the blog I have been pretty careful to avoid outright partisanship.  Partly this is a matter of personality: it comes more naturally to me to play the disinterested analyst role than the role of an activist and partisan.  At the same time, it's impossible not to notice that for the issues I most care about - climate, energy, environment, and future of society - the Democratic party (while far from perfect) is currently a lot better than the Republican party.  This is so overwhelmingly true at present that I don't feel a need to make an argument in detail: it's become so extreme that Republican politicians almost uniformly have to be delusional on climate change (or at least pretend to be).  Thus I've struggled with whether I'm being too coy in not taking an explicitly partisan position: actively urging readers to political action, or endorsing Democratic candidates, for example.

For now, at least, I have decided not to do that.  My reasoning is as follows: I think in the deepest part of its soul, what the Republican party is about is protecting the interests of the most economically successful members of society: hence the focus on lightening their taxation burden, reducing regulations that might impede their enterprises, promoting their right to pass their wealth to their children, etc.  I don't lack all sympathy for this agenda: I think the most economically successful people are particularly important to society at large and it is possible for a society to go too far in the direction of impeding them (though that is not my diagnosis of the main problem for the US in 2012).

And I note that climate change, drought, running low on energy or food (with the resulting instability, riots, etc) are not in the long-term interests of the wealthy either.  Wealth is a social construct that is entirely dependent on a reasonable degree of political and economic stability.  During times of disorder, the wealthy are at risk of losing everything they have gained, ranging from those families that lost the family fortune in the Great Depression - or the 90% marginal tax rates and high estate taxes that followed - to the extremes of the French Revolution when much of the elite were slaughtered in a genocidal frenzy.  I'm not aware of a single Roman Villa that evolved smoothly into a medieval manor.

So, if we are to have any hope of some kind of fairly orderly transition into a carbon-neutral sustainable society, at some point our millionaires and billionaires have to come to their senses and recognize that destabilizing key planetary systems on which we all depend is not going to do them and their children the slightest bit of good.  In fact, we need talented green entrepreneurs and investors to be brilliant and wildly successful perhaps more than we need any other single thing.

And so I want this blog to be a hospitable environment for successful individuals who can be persuaded that these problems are important and should be worked on.  And, at least for the time being, I think that is best served by continuing to avoid explicit partisanship.

European Retail Trade


The latest data show that consumers in Europe as a whole seemed to have reached the steady state economy.  However, inside the Eurozone, retail spending continues to slide slowly.  Combined with the unemployment data, we can see that Europe continues to stagnate - it has not solved its fundamental problems, but nor has it slid into acute crisis.

Arctic Sea Ice Volume


In response to this morning's links post, commenter Stephen B argued that:
I don't think one needs to be any kind of climate scientist to understand what is about to happen to the remaining ice. In the next 3 years, at some point, the remaining ice is going to be so thin and so relatively fresh, that late one summer in say, August of 2014 to 17, scientists are going to look at their satellite data, and see essentially zero ice. Anybody that's watched a large lake or bay melt understands how they go. First, the edges fray. Some chunks break off, but the main slab grows thinner, wetter, darker, and more "rotten." Then one day in the spring the whole thing, say like 75% of the surface, just breaks up to slush in a matter of hours and it's gone.
I grabbed the ice volume data from Piomas, computed the minimum volume each year, and plotted the result above.  Note that 2012 is not final as there's still several weeks of the normal melt season left.

The purple line is a linear trend - explaining 82% of the variance.  It clearly has systematic problems - the ice collapse is accelerating, not just proceeding linearly.

A quadratic (red) is a visibly much better fit and explains 92% of the variance.  The quadratic hits zero in 2017.

It doesn't seem crazy to think that the Arctic will be ice free in September sometime this decade.

Strange that explorers competed for years to travel by sled to a place that will no longer exist.  Maybe I'm naive, but it seems this will change the debate about climate change - the complete absence of a polar ice cap seems much easier for an ordinary person to understand, versus complex arguments about data-analysis on global temperature statistics, requiring that you trust scientists and their computer models.  Arguing that climate change isn't happening will become akin to arguing that the earth is flat.

  • The chart above is new electricity generation by fuel source over time in the US.
  • The challenges ahead in battery research.  (I would be somewhat more optimistic - making some allowance that researchers emphasize problems as motivation for their research - and also that commercialization is not about solving the whole problem at once but rather finding a series of increasingly large niches that eventually scale to the whole market - but much of the post is very informative).
  • Climate is Really Changing - nothing new but a nice concise summary from Tamino.
  • Progression of obesity in OECD countries.
  • What the US needs to do to balance the budget.
  • Chinese PMIs continue to look weak.  This is consistent with the weak global trade data and oil supply that is not expanding.

Bleg: Thin Film Solar Modules on Aging Barn Roof

A quick question: I'm starting to research installing solar at our place near Ithaca (always my intention from when we bought it, but other projects had to happen first).

It seems to me appealing to put the solar power on the barn rather than the house:
  • It has a much larger area (ie more power)
  • The cosmetic impact from the road will be lower
Since the barn roof structure is not that heavy, it probably makes a lot more sense to apply flexible CIGs modules (eg like these Global Solar modules) than to use conventional modules.  These flexible modules are generally glued to a metal roof (eg with mastic).  So one question is whether folks have experience with these modules and prefer one brand to another?

Secondly - the sheet metal on the barn roof is a few decades old.  While the roof isn't in imminent danger of failing, about 50% of the roof area now looks rusty and about 50% still has the galvanized surface.  I've already had a contractor offer to cover the roof with an aluminized asphalt product to extend the life of the metal.  Clearly, it's not desirable to attach solar modules to metal with a noticeably shorter life than the modules.

One idea that occurs to me is to use an aluminized asphalt product to adhere the modules to the metal, and cover the whole roof at the same time in the interests of preserving it.

Does anyone have any experience with a similar situation?

Saudi Aramco Network Hit With Cyber-Attack

Apparently they shut down the network:
Saudi Aramco, Saudi Arabia’s national oil company and the largest in the world, has confirmed that is has been hit by a cyber attack that resulted in malware infecting user workstations, but did not affect other parts of its network.

“On Wednesday, Aug. 15, 2012, an official at Saudi Aramco confirmed that the company has isolated all its electronic systems from outside access as an early precautionary measure that was taken following a sudden disruption that affected some of the sectors of its electronic network,” the company wrote in a statement.

“The disruption was suspected to be the result of a virus that had infected personal workstations without affecting the primary components of the network.”

The company did not comment on the vector of attack or who may behind it, but insists its core operations have not been impacted as a result of the security breach.
Word is that this was due to the Disttrack malware that was only discovered yesterday:
Malware being used in a new series of targeted attacks has bucked the trend, choosing to destroy the computers it infects rather than just stealing sensitive information, security researchers said.

Called "Disttrack", the malware corrupts files, overwrites the infected machine's master boot record, and destroys the data so that it can't be recovered, according to reports from Symantec Security Response, Kaspersky Lab's Global Research and Analysis Team, and McAfee on Thursday. Disttrack has been observed in the Shamoon attacks, which has already affected at least one organization in the energy sector, Symantec said, but the company declined to provide any other details about the affected organization(s).
Given the unusual destructiveness of the malware, one can't help suspecting an Iranian or Syrian revenge operation - but no evidence one way or another at present.  Anyway, pretty interesting to have the world's largest oil company victim of a major cyberterrorism incident.

Total Available Renewable Resource

Several commenters questioned Friday's post on the grounds that the total amount of solar and wind power potentially available is insufficient to power modern civilization

This is incorrect.

Total available wind power available on land and near shore has been estimated at 72TW.   This is close to five times current total primary energy consumption, and still more than twice as large as energy consumption in 2040 (extrapolating at the 2.7% growth rate of the last decade).

Of course, not all technically and economically feasible wind sites are politically feasible.  Thus it's important that total incoming solar radiation is also very large.  Top of the atmosphere incoming solar radiation is 174000TW.  If we just look at the world's desert areas, they represent about a third of the global land area, itself about 30% of the total surface.  Allowing 30% losses in the atmosphere over deserts, and throwing out something for Antarctica (a desert, but not a very useful one for solar power), we end up with something in the ballpark of 7000TW of available solar energy from deserts alone.  This is hundreds of times larger than current civilizational energy consumption.

Therefore, constraints on our ability to utilize renewables are political and economic, not ultimate physical ones; there is plenty of renewable energy out there.

Eurozone Unemployment


The numbers came out yesterday and are as above - a slight stall, but no real evidence of a reversal.  Also, every one of the PIIGS countries saw their unemployment rate get worse in the latest month.

So there is still no sign of stabilization in the real economy in Europe.

Administrivia: MWF Schedule

Just a short note on blog schedule. Historically, I aimed on this blog to do a post once each morning on weekday mornings.  This was never perfectly true: I always missed the odd morning when something didn't work out, and have occasionally added extra lunchtime or weekend posts as time and interest allowed.

However, in recent months I've had a lot of work-related travel and I've been failing more consistently to do more than a few posts each week.  I think it would be better to acknowledge this explicitly and provide readers with a bit more predictability by switching to a target schedule of posting Monday, Wednesday, and Friday mornings.  Again, this won't be perfectly true, but I'll aim to make it true 90% of the time.  Posts will continue to be primarily quantitative/empirical exploration of issues in the area of energy/environment/economy with a focus on things that I think are important but not well-enough covered elsewhere.

Bleg on Minisplit Ductless Airsource Heat Pumps

Sources have told me that in the last few years it has become possible to heat buildings in cold climates (eg the US northeast) with the latest generation of ductless minisplit air-source heat pumps.  I am seeking detailed technical information on the performance of these kinds of systems that would allow me to evaluate the low temperature limits, thermodynamic efficiency, and cost-effectiveness of doing this in a retrofit context.  I haven't easily come up with sufficiently detailed information in Googling around - can any readers point me in the right direction?

Tight Oil could not Render OPEC Irrelevant

Steve Levine has a blog post discussing the idea that the "unfolding new age of fossil fuel abundance" will have profound effects on various things, including OPEC:
With prices dropping and competing supplies flowing from numerous new producers, OPEC will lose much relative influence, and may simply cease to be a pivotal economic player. "OPEC will descend into chaos as an organization," said John Hofmeister, former president of Shell USA. "They don't know now how much they are hated by the entire world. But they will find out as things unfold."
The key factor behind this kind of thinking is the rapid rise of production of oil from tight rocks like the Bakken in North Dakota and the Eagle Ford in Texas.  I haven't taken a strong position on what the limits of production are from these sources - it just isn't clear to me yet from the data that I have available.  But we could certainly place some limits on how much geopolitical impact this could have on OPEC.
