The Return of London's Fog

London’s fogs may be about to make a comeback. Christine Corton, in the NYT:

In January, researchers at King’s College London announced that pollution levels on Oxford Street, in central London, had exceeded limits set for the entire year in just the first four days of 2015. Similarly alarming numbers have been recorded for other streets in the city — and yet the mayor, Boris Johnson, has delayed implementation of stricter air-quality measures until 2020.

What’s happening in London is being played out in cities worldwide, as efforts to curtail the onslaught of air pollution are stymied by short-term vested interests, with potentially disastrous results.

I just experienced a particular, particulate version of this hell first-hand in Delhi. For the last few days of my trip, a dense, thick haze - clearly not an innocuous fog - permeated the city and surrounding environs. On one trip back to our flat, all of my fellow taxi passengers complained of burning eyes and sore throats.

The closest PM monitor during that drive back — actually quite far from us — read over 250 �g/m3. That’s around 10x higher than a ‘bad’ day in the US. Moreover, we guessed that the levels we were experiencing were closer to 350 �g/m3. As a point of reference, the maximum mean hourly PM2.5 concentration in London since 2008 was approximately 30 �g/m3.

Corton points to a behavioral component to the historic London Fog episodes — a parallel I find particularly interesting:

There was a cultural component, too. The British were wedded to their open fires. Closed stoves, popular throughout much of Europe, especially in Germany, were shunned by Londoners. During World War I, Britons were exhorted, in the words of the famous song, to “keep the home fires burning.” Politicians were simply not willing to risk unpopularity by forcing Londoners to stop using coal and go over to gas or electric heating instead. In Britain today, in an echo of these earlier concerns, the government is cutting subsidies for onshore wind and solar farms, anxious not to offend voters in rural areas where such facilities would be built.

It took a disaster to force London to change direction. In 1952, a “great killer fog” lasted five days and killed an estimated 4,000 people. In a Britain trying to turn a corner after the death and destruction of the Blitz, this was unacceptable. A Clean Air Act was passed in 1956, forcing Londoners to burn smokeless fuel or switch to gas or electricity, power sources that had become much cheaper as these industries expanded.

Let’s hope that policy levers and momentum — not a disaster — can help transition away from solid fuels in India and beyond.

Conditional cash transfers for energy poverty... and murder reduction

Conditional cash transfers — paying people to change behavior, usually to spur positive ‘social’ outcomes — continue to be in the news. Much of the focus is on their use as poverty reduction tools (Bolsa Familia in Brazil, JSY in India) through encouraging behaviors like antenatal care visits and sending children to school.

Two recent article — one in the NYT, one in Mother Jones — highlighted the use of CCTs and other targeted cash transfer tools for dramatically different outcomes.

In the NYT, poverty and energy issues were at the fore:

The Indian government subsidizes households’ purchases of cooking gas; these subsidies amounted to about $8 billion last year. Until recently, subsidies were provided by selling cylinders to beneficiaries at below-market prices. Now, prices have been deregulated, and the subsidy is delivered by depositing cash directly into beneficiaries’ bank accounts, which are linked to cellphones, so that only eligible beneficiaries — not “ghost” intermediaries — receive transfers.

Under the previous arrangement, the large gap between subsidized and unsubsidized prices created a thriving black market, where distributors diverted subsidized gas away from households to businesses for a premium. In new research with Prabhat Barnwal, an economist at Columbia University, we find that cash transfers reduced these “leakages,” resulting in estimated fiscal savings of about $2 billion.

There’s even more “smart” targeting coming soon. My advisor and colleagues in India have been working to “[describe] how the LPG subsidy could be even more completely targeted to the poor without any actual ‘taking away’ of the subsidy from the rich and middle class, which would likely trigger heavy political push back. As a result, several hundred million additional poor Indians could have affordable access in the next decade without increasing subsidy costs to the government (indeed probably reducing them) or LPG imports — both not likely to be popular.”

In Mother Jones, CCTs were being used to reduce murders:

Richmond hired consultants to come up with ideas, and in turn, the consultants approached [Devone] Boggan. It was obvious that heavy-handed tactics like police sweeps weren’t the solution. More than anything, Boggan, who’d been working to keep teen offenders out of prison, was struck by the pettiness of it all. The things that could get someone shot in Richmond were as trivial as stepping out to buy a bag of chips at the wrong time or in the wrong place. Boggan wondered: What if we identified the most likely perpetrators and paid them to stay out of trouble?

It seems to be working.

It was a crazy idea. But since ONS was established, the city’s murder rate has plunged steadily. In 2013, it dropped to 15 homicides per 100,000 residents—a 33 year low. In 2014, it dropped again. Boggan and his staff maintained that their program was responsible for a lot of that drop-off by keeping the highest-risk young men alive—and out of prison. Now they have a study to back them up.

On Monday, researchers from the National Council on Crime and Delinquency, a non-profit, published a process evaluation of ONS, studying its impact seven years in. The conclusion was positive: “While a number of factors including policy changes, policing efforts, an improving economic climate, and an overall decline in crime may have helped to facilitate this shift, many individuals interviewed for this evaluation cite the work of the ONS, which began in late 2007, as a strong contributing factor in a collaborative effort to decrease violence in Richmond.”

India is building millions of toilets, but that's the easy part

Rama Lakshmi, in the Washington Post, on the push for many, many more toilets throughout India:

Modi has made toilet-building and sanitation a rallying cry since October. He has enlisted large companies to help. In the past year, his government has built more than 5.8 million toilets — up from 4.9 million the previous year. But reports show that many of them are unused or that they are being used to store grain, clothes or to tether goats, thwarting Modi’s sanitation revolution.

“Even as we accelerate toilet construction now, much more needs to be done to persuade people to use them,” said Chaudhary Birender Singh, India’s minister for rural development, sanitation and drinking water. “For long, we assumed that if the toilets are built, people will automatically use it. But we have to diligently monitor the use over a period of time and reward them with cash incentives to the village councils at every stage. Only then will it become a daily habit.”

This all sounds really familiar.

Ye Olde Smog Meringue

Nicola Twilley, writing at

After running around New York City in order to source our precursor ingredients (a huge thanks to Kent Kirshenbaum, chemistry professor at NYU and co-founder of the Experimental Cuising Collective), we spent Thursday afternoon and evening in the kitchens of Baz Bagel (excellent bagels, amazing ramp cream cheese, and truly lovely people) assembling the cart, mixing different chemical precursors, and then “baking” them under UV light to form a London peasouper, a 1950s Los Angeles photochemical smog, and a present-day air-quality event in Atlanta.

We chose these three places and times to showcase three of the classic “types” that atmospheric scientists use to characterize smogs: 1950s London was a sulfur- and particulate-heavy fog, whereas 1950s Los Angeles was a photochemical smog created by the reactions between sunlight, NOx, and partially combusted hydrocarbons. Present-day Beijing often experiences London-style atmospheric conditions, whereas Mexico City’s smog is in the Angeleno style.

Meanwhile, at its worst, Atlanta’s atmosphere is similar in composition to that of Los Angeles, but with the addition of biogenic emissions. An estimated ten percent of emissions in Atlanta are from a class of chemicals known as terpenes, from organic sources such as pine trees and decaying green matter. We had also hoped to create a Central Valley smog as well, but time got the better of us.

Each city’s different precursor emissions and weather conditions produce a different kind of smog, with distinct chemical characteristics—and a unique flavour.

LED lighting: an accelerated learning curve?

News from Samsung (exiting the LED market) and Philips (spinning off their LED division) would seem to indicate rapid learning in the LED space. From Reuters:

Analysts say Samsung Electronics’ retreat reflects the growing competition from Chinese manufacturers even as demand for LED lighting remains strong. LED lamps last 10 times longer than fluorescent bulbs and 100 times longer than traditional incandescent tungsten filament bulbs.

“It appears that Samsung decided to fold the business because price competition was so fierce and there was not a lot of room for growth going forward,” said Seoul-based IM Investment analyst Lee Min-hee.

Philips said in September that it will spin off its lighting business to expand its higher-margin healthcare and consumer divisions. Two month earlier, Germany’s Osram Licht AG , which also makes LED lights, announced a cost-cutting plan that included nearly 8,000 job cuts.

Jason Snell put it best:

So, bad news for Samsung and other businesses betting on big margins for bulbs, but good news for everyone else.

Paulson on Climate Change and the Price of Inaction

Henry M. Paulson, writing in the NYT:

In a future with more severe storms, deeper droughts, longer fire seasons and rising seas that imperil coastal cities, public funding to pay for adaptations and disaster relief will add significantly to our fiscal deficit and threaten our long-term economic security. So it is perverse that those who want limited government and rail against bailouts would put the economy at risk by ignoring climate change.

This is short-termism. There is a tendency, particularly in government and politics, to avoid focusing on difficult problems until they balloon into crisis. We would be fools to wait for that to happen to our climate.

When you run a company, you want to hand it off in better shape than you found it. In the same way, just as we shouldn’t leave our children or grandchildren with mountains of national debt and unsustainable entitlement programs, we shouldn’t leave them with the economic and environmental costs of climate change. Republicans must not shrink from this issue. Risk management is a conservative principle, as is preserving our natural environment for future generations. We are, after all, the party of Teddy Roosevelt.

Naomi Klein on Climate Change

Well-written and well thought piece on some of the challenges surrounding climate change from Naomi Klein in The Nation:

Another part of what makes climate change so very difficult for us to grasp is that ours is a culture of the perpetual present, one that deliberately severs itself from the past that created us as well as the future we are shaping with our actions. Climate change is about how what we did generations in the past will inescapably affect not just the present, but generations in the future. These time frames are a language that has become foreign to most of us.

This is not about passing individual judgment, nor about berating ourselves for our shallowness or rootlessness. Rather, it is about recognizing that we are products of an industrial project, one intimately, historically linked to fossil fuels.

And just as we have changed before, we can change again. After listening to the great farmer-poet Wendell Berry deliver a lecture on how we each have a duty to love our “homeplace” more than any other, I asked him if he had any advice for rootless people like me and my friends, who live in our computers and always seem to be shopping for a home. “Stop somewhere,” he replied. “And begin the thousand-year-long process of knowing that place.”

That’s good advice on lots of levels. Because in order to win this fight of our lives, we all need a place to stand.

Some more graphs of Beijing's Air Pollution

A bunch of folks across the internet have been doing some great stuff with the air quality data coming out of China via official channels and the US Embassy twitter feeds. My advisor asked for some graphs of available data. They are posted below (all were created in R using ggplot2). If time ever permits, I’ll post some interactive visualizations.

Earth Island Journal's Conversation with Naomi Klein

A good interview with Naomi Klein leading her new book coming out in 2014. Read the whole thing here.

You’ve said that progressives’ narratives are insufficient. What would be an alternative narrative to turn this situation around?

Well, I think the narrative that got us into this - that’s part of the reason why you have climate change denialism being such as powerful force in North America and in Australia - is really tied to the frontier mentality. It’s really tied to the idea of there always being more. We live on lands that were supposedly innocent, “discovered” lands where nature was so abundant. You could not imagine depletion ever. These are foundational myths.

And so I’ve taken a huge amount of hope from the emergence of the Idle No More movement, because of what I see as a tremendous generosity of spirit from Indigenous leadership right now to educate us in another narrative. I just did a panel with Idle No More and I was the only non-Native speaker at this event, and the other Native speakers were all saying we want to play this leadership role. It’s actually taken a long time to get to that point. There’s been so much abuse heaped upon these communities, and so much rightful anger at the people who stole their lands. This is the first time that I’ve seen this openness, open willingness that we have something to bring, we want to lead, we want to model another way which relates to the land. So that’s where I am getting a lot of hope right now.

The impacts of Idle No More are really not understood. My husband is making a documentary that goes with this book, and he’s directing it right now in Montana, and we’ve been doing a lot of filming on the northern Cheyenne reservation because there’s a huge, huge coal deposit that they’ve been debating for a lot of years - whether or not to dig out this coal. And it was really looking like they were going to dig it up. It goes against their prophecies, and it’s just very painful. Now there’s just this new generation of young people on that reserve who are determined to leave that coal in the ground, and are training themselves to do solar and wind, and they all talk about Idle No More. I think there’s something very powerful going on. In Canada it’s a very big deal. It’s very big deal in all of North America, because of the huge amount of untapped energy, fossil fuel energy, that is on Indigenous land. That goes for Arctic oil. It certainly goes for the tar sands. It goes for where they want to lay those pipelines. It goes for where the natural gas is. It goes for where the major coal deposits are in the US. I think in Canada we take Indigenous rights more seriously than in the US. I hope that will change.

Rim Fire images from NASA & the KPCC Fire Tracker

Devastating. KPCC has an interesting, interactive tool for monitoring California’s wildfires. A bit is embedded below, but the whole thing is worth a look.

NASA’s posted a number of photos of the fire from space. A smattering are embedded below.

In some of the photos, you can see the plume from the Rim Fire and the plume from the American Fire in Tahoe National Forest.

Reno’s been adversely affected by the plume from the Rim Fire, reporting unhealthy on their AQI (can’t find any numbers, at the moment); NASA projects that the plume is impacting AQ in 4 states.

Good luck to the firefighters and rangers working to control the blaze. Our thoughts are with them and others in the surrounding communities.

Past EPA Administrators: The US "must move now on substantive steps to curb climate change, at home and internationally."

Writing in an NYT Editorial, four previous EPA administrators make a strong case for climate action now.

Climate change puts all our progress and our successes at risk. If we could articulate one framework for successful governance, perhaps it should be this: When confronted by a problem, deal with it. Look at the facts, cut through the extraneous, devise a workable solution and get it done.

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 writers are former administrators of the Environmental Protection Agency: William D. Ruckelshaus, from its founding in 1970 to 1973, and again from 1983 to 1985; Lee M. Thomas, from 1985 to 1989; William K. Reilly, from 1989 to 1993; and Christine Todd Whitman, from 2001 to 2003.

EIA: World energy consumption will increase 56% by 2040

EIA’s recently released International Energy Outlook 2013 (IEO2013) projects that world energy consumption will grow by 56% between 2010 and 2040, from 524 quadrillion British thermal units (Btu) to 820 quadrillion Btu. Most of this growth will come from non-OECD (non-Organization for Economic Cooperation and Development) countries, where demand is driven by strong economic growth.

Renewable energy and nuclear power are the world’s fastest-growing energy sources, each increasing 2.5% per year. However, fossil fuels continue to supply nearly 80% of world energy use through 2040. Natural gas is the fastest-growing fossil fuel, as global supplies of tight gas, shale gas, and coalbed methane increase.

The industrial sector continues to account for the largest share of delivered energy consumption and is projected to consume more than half of global delivered energy in 2040. Based on current policies and regulations governing fossil fuel use, global energy-related carbon dioxide emissions are projected to rise to 45 billion metric tons in 2040, a 46% increase from 2010. Economic growth in developing nations, fueled by a continued reliance on fossil fuels, accounts for most of the emissions increases.

Report of the US-China Climate Change Working Group

From the report:

We have prepared this Report mindful of the overwhelming scientific consensus about anthropogenic climate change and its worsening impacts, as well as the urgent need to intensify global efforts to combat climate change. Rising temperatures are predicted to lead to sea level rise that could affect tens of millions of people around the world, as well as more frequent and intense heat waves, intensified urban smog, and droughts and floods in our most productive agricultural regions. Global climate change represents a grave threat to the economic livelihood and security of all nations, but it also represents a significant opportunity for sustainable development that will benefit both current and future generations. We believe that ambitious domestic action by China and the United States is more critical than ever. China has given high priority to building an “Ecological Civilization” by striving for green, circular and low-carbon development. It has adopted proactive policies and measures to mitigate and adapt to climate change. The United States is implementing robust policies to promote renewable energy, enhance energy efficiency, and reduce emissions from transportation, buildings, and the power sector. Both countries recognize the need to work together to continue and build on these important efforts.

Five key areas of collaboration were outlined.

  1. Emission reductions from heavy-duty and other vehicles.
  2. Smart Grids
  3. Carbon capture, utilization, and storage.
  4. Collecting and managing greenhouse gas emissions data.
  5. Energy efficiency in buildings and industry.

There’s an explicit acknowledgement of coal as a bad actor here, but nothing explicated about moving from dirty to clean fuels for generation of electricity. Some mentions of co-benefits, as well.

NYTimes: "A single word tucked into a presidential speech...

Justin Gillis, writing in the NYT about Obama's choice to use the word divest:

He knows that if he is to get serious climate policies on the books before his term ends in 2017, he needs a mass political movement pushing for stronger action. No broad movement has materialized in the United States; and its student activists are the closest thing so far, which may be why Mr. Obama gazes fondly in their direction.

�I�m going to need all of you to educate your classmates, your colleagues, your parents, your friends,� he said plaintively at Georgetown. �What we need in this fight are citizens who will stand up, and speak up, and compel us to do what this moment demands.�

Let's hope the movement towards divestment grows.

Details on 'Power Africa,' the White House's new plan for electrification across sub-Saharan Africa

From the White House:

Today the President announced Power Africa, a new initiative to double access to power in sub-Saharan Africa. More than two-thirds of the population of sub-Saharan Africa is without electricity, and more than 85 percent of those living in rural areas lack access. Power Africa will build on Africa’s enormous power potential, including new discoveries of vast reserves of oil and gas, and the potential to develop clean geothermal, hydro, wind and solar energy. It will help countries develop newly-discovered resources responsibly, build out power generation and transmission, and expand the reach of mini-grid and off-grid solutions.

According to the International Energy Agency, sub-Saharan Africa will require more than $300 billion in investment to achieve universal electricity access by 2030. Only with greater private sector investment can the promise of Power Africa be realized. With an initial set of six partner countries in its first phase, Power Africa will add more than 10,000 megawatts of cleaner, more efficient electricity generation capacity. It will increase electricity access by at least 20 million new households and commercial entities with on-grid, mini-grid, and off-grid solutions. And it will enhance energy resource management capabilities, allowing partner countries to meet their critical energy needs and achieve greater energy security.

As that first paragraph points out, this is inherently an issue of rural energy — and of household energy. The following bit seems a bit… optimistic:

Power Africa will work in collaboration with partner countries to ensure the path forward on oil and gas development maximizes the benefits to the people of Africa, while also ensuring that development proceeds in a timely, financially sound, inclusive, transparent and environmentally sustainable manner.

The 'Social Cost Of Carbon' Is Almost Double What The Government Previously Thought

Think Progress has a nice summary of the report out of the Obama administration updating the social cost of carbon (SCC). From the report’s executive summary:

The SCC estimates using the updated versions of the models are higher than those reported in the 2010 TSD. By way of comparison, the four 2020 SCC estimates reported in the 2010 TSD were $7, $26, $42 and $81 (2007$). The corresponding four updated SCC estimates for 2020 are $12, $43, $65, and $129 (2007$). The model updates that are relevant to the SCC estimates include: an explicit representation of sea level rise damages in the DICE and PAGE models; updated adaptation assumptions, revisions to ensure damages are constrained by GDP, updated regional scaling of damages, and a revised treatment of potentially abrupt shifts in climate damages in the PAGE model; an updated carbon cycle in the DICE model; and updated damage functions for sea level rise impacts, the agricultural sector, and reduced space heating requirements, as well as changes to the transient response of temperature to the buildup of GHG concentrations and the inclusion of indirect effects of methane emissions in the FUND model. The SCC estimates vary by year, and the following table summarizes the revised SCC estimates from 2010 through 2050.

After reviewing the full document, the changes update the science to the state of current understanding. As such, the projections offered within are more current (and based on more evolved science) than previously SCC estimates. The conclusions from the report are significant, but seem to overplay the US’s actions and role to date:

However, the climate change problem is highly unusual in at least two respects. First, it involves a global externality: emissions of most greenhouse gases contribute to damages around the world even when they are emitted in the United States. Consequently, to address the global nature of the problem, the SCC must incorporate the full (global) damages caused by GHG emissions. Second, climate change presents a problem that the United States alone cannot solve. Even if the United States were to reduce its greenhouse gas emissions to zero, that step would be far from enough to avoid substantial climate change. Other countries would also need to take action to reduce emissions if significant changes in the global climate are to be avoided. Emphasizing the need for a global solution to a global problem, the United States has been actively involved in seeking international agreements to reduce emissions and in encouraging other nations, including emerging major economies, to take significant steps to reduce emissions.

This is a step in the right direction, but dodges real leadership.

Ella Chou: What Would China's Carbon Tax Regime Look Like

A thoughtful and insightful overview of the proposed carbon/environmental tax by Harvard graduate student Ella Chou. Some excerpts follow.

The first thing I want to clarify is that calling it a “carbon tax” would be a gross misnomer, because for a long time to come, the majority of the tax collected from this would still be from what used to be called “pollution discharge fees”, not from taxing carbon emissions.

The tax on carbon would in fact be puny. The Xinhua report noted that previous MOF expert suggestion for the carbon tax was 10 yuan (US $1.5) per ton of carbon dioxide in 2012, with gradual increase to 50 yuan ($7.9) per ton by 2020.

…[T]he tax on coal in China is merely 2-3 yuan (US $0.4) per ton, and 8 yuan (US $1.27) per ton for charred coal, even though the price of coal has increased to several hundreds of yuan per ton.

The point of a carbon tax, be in China or elsewhere, is to set the price signal straight. We tax income; we tax property; we tax goods and services — all the things we want more of, so wouldn’t it be logic to actually tax the thing we want less of: pollution?

I should note that the proportion of environmental tax in the overall revenue of any level of government would be tiny, as is the pollution discharge fee portion of the revenue mix now. Local governments would continue to come up ways to give industries tax rebates and subsidies to attract them to their own jurisdictions, so the effect of the environmental tax or the carbon tax on the industries would be negligible. Standardizing fees into a tax is a step in the right direction. China can use a price on carbon, and environmental issues in general, as a starting point to address the price distortions that are stifling its long-term growth.

Traditional cooking and household energy use in the Library of Congress online archives

In the past few weeks, a lot of people have been mining the LoC photo databases for images of public works posters, images of cities early in their development, etc. The archive is outstanding and a lot of the pictures, negatives, schematics, and drawings are available online in multiple resolutions.

I ran some searches for household energy, hearths, cooking fire, cooking stoves, etc and found a number of fascinating results. Many of the pictures from the US were not available online yet - in particular, two libraries of “cooking technologies” from the 1920s and 1930s weren’t around. I’m working on getting access to those through some data request channels. A few that were accessible are below. The majority are from Sikkim and were taken by Alice Kandell between 1965 and 1971. The large one above is supposedly from Jerusalem and was taken between 1900-1920. The seventh one below is from 1908 in Paterna, Spain.

Clearly a wealth of interesting historical information in the archives. Looking forward to further explorations.

EPA Releases its "Climate Change Adaptation Plan"

We live in a world in which the climate is changing. Changes in climate have occurred since the formation of the planet. But humans are now influencing Earth’s climate and causing it to change in unprecedented ways.

It is in this rapidly changing world that EPA is working to fulfill its mission to protect human health and the environment. Many of the outcomes EPA is working to attain (e.g., clean air, safe drinking water) are sensitive to changes in weather and climate. Until now, EPA has been able to assume that climate is relatively stable and future climate will mirror past climate. However, with climate changing more rapidly than society has experienced in the past, the past is no longer a good predictor of the future. Climate change is posing new challenges to EPA’s ability to fulfill its mission.

EPA: Greenhouse Gas Emissions from Large Facilities

A cool tool for visualizing large GHG emitters in the US.

Through EPA’s Greenhouse Gas Reporting Program, facilities that emit 25,000 metric tons or more per year of GHGs are required to annually report their GHG emissions to EPA. The facilities are known as direct emitters. The data reported by direct emitters provides a “bottom-up” accounting of the major sources of GHG emissions associated with stationary fuel combustion and industrial processes. Well over half of total U.S. greenhouse gas emissions are accounted for in this facility level data set, including nearly complete coverage of major emitting sectors such as power plants and refineries.
