A sustainable future is within reach, but it won’t prevent the world from experiencing the potentially catastrophic environmental and political consequences of climate change and environmental degradation, former Secretary of Energy Steven Chu told a Stanford audience.
Chu, who shared the 1997 Nobel Prize in Physics and served as the energy secretary under President Barack Obama from 2009 to 2013, held a seminar at CISAC on Tuesday on climate change, sustainability and security.
The consequences of the damage wrought by unsustainable resource depletion and air pollution will manifest in a hotter, more dangerous world, said the Stanford physics professor.
Average global temperatures have skyrocketed past normal levels since the Industrial Revolution and have plateaued in the last few months at the highest points in history. Chu said the plateau is likely due to it taking a long time for the lower depths of the oceans to warm up.
“There is a built-in time delay between committing damage, which we’ve already done, and feeling the true consequences. All we can say is that temperatures are likely to climb again, we just don’t know when – could be 50 to 100 years – and by how much,” said Chu.
Even if the world were to stop using coal, oil, and natural gas today, he said, it would not stop the oncoming consequences. “It’s like a long-time chain-smoker who stops smoking. Stopping does not necessarily prevent the occurrence of lung cancer.”
Chu said the battle between scientists and the tobacco industry in the 20th century is analogous to today’s conflict between scientists and the energy industries.
“A lot of what you hear from the incumbent energy industries and their representatives are the same kinds of arguments that the tobacco industry made when the science showing the harm cigarettes caused came out,” said Chu.
Ironically, the same science showing the damage cigarettes cause to health can be used to demonstrate the hazards of air pollution today.
Chu noted that a recent study found that for every 10 micrograms of pollution per cubic meter, the chances of contracting lung cancer increases 36 percent. This lends alarming perspective to pollution in places such as China and India.

The U.S. Embassy in Beijing tracks air pollution levels daily.
“The average level of air pollution was 194 micrograms per cubic meter. So it’s possible that breathing the average air in Beijing is equivalent to smoking a pack of cigarettes a day,” he said. “Even if it’s a third of that, it’s still really bad. But again, there is going to be a lag time between now and a possible rash of deaths by lung cancer.
In addition to causing large-scale health crises, global warming and environmental degradation may exacerbate, or even cause, potential conflicts between countries.
“I think water insecurity concerns me more than even rising sea levels,” said Chu, noting that today’s conflicts in the Middle East and North Africa are exacerbated by water insecurity.
“India is already nervous that China will direct water runoff from the Himalayas to water-starved Northern China and away from India or Bangladesh, which are also water-starved,” he said. “India is also concerned that millions of Bangladeshis could become environmental refugees and start streaming into India.”
Chu recalled that when he was energy secretary, one of his biggest climate-change allies was the Department of Defense
“They will be the ones called on to help with those stresses and they see serious geopolitical risks due to climate change,” he said.
Despite the dangers ahead, Chu is optimistic about great strides in sustainable technology.
Chu and some of his colleagues studied a phenomenon that may bode well for creating a more environmentally friendly economy: putting efficiency standards on electronic appliances, which eventually could lead to a decline in the cost of appliances.
In addition to economical energy standards, new and cheaper green energy technology is within sight. Chu is working with Stanford Professor Yi Cui on creating a lithium-sulfur battery that may be significantly lighter than the current electric batteries used by cars such as Tesla and charge 200 miles in 10 minutes.
Additionally, wind energy is set to become cheaper than natural gas. Chu said that in the Midwest, where the wind is best and cheapest, contracts are selling anywhere between 2.5 and 3 cents per kilowatt-hour. If you build a new natural gas plant, it would be about 5 cents per kilowatt-hour.
“To be fair, wind does have the benefit of a production tax credit and if you take that away, wind would be somewhere around 5.5 cents per kilowatt-hour. But I think within the next dozen years wind will, on its own, be cheaper than natural gas,” he said.
Solar is even more surprising, said Chu. In July 2008, contracts were going for 18 to 20 cents per kilowatt-hour. In Texas in 2014, two contracts were signed one for 5 cents and the other for 4.8 cents per kilowatt-hour. Solar has the advantage of being scalable and the amount of solar resources available around the world is substantial.
“There’s plenty of solar energy available to power the entire world several times over,” he said.
Nonetheless, public policy nudges are still needed.
“There is still no serious discussion in the U.S. about creating a national grid with long distance transmission lines, which will be necessary for a sustainable future. But before that can happen, the campaign by incumbent industries to discredit and doubt climate science has to be defeated.”

Lobbying and Campaign Finance
-
On November 14-15, the Program on American Democracy in Comparative Perspective hosted a conference on Lobbying and Campaign Finance. The conference brought together academics, practitioners, and lawyers to understand the impact of money in politics on a variety of outcomes, including special interest capture, democratic distortion, and inequality. The conference provided a rare opportunity to combine discussions of potential political reforms with evaluation of recent empirical findings in the area of lobbying and campaign finance. Participants covered a range of topics, including lobbying in Congress and in executive agencies; the relationship between patterns of campaign finance and partisan polarization; campaign finance laws, political parties, and special interest influence; and the regulation of lobbying and political money in other advanced democracies. The conference report summarizes the reform ideas that emerged from the conference discussions, including increasing soft money to political parties, disclosure of dark money, limiting lobbying access through the revolving door, and increasing the capacity of government.
The conference was held at the William and Flora Hewlett Foundation, a donor to the Program on American Democracy.

‘Don’t Ask, Don’t Tell’ Secrecy, Security, and Oversight of Targeted Killing Operations
-
Abstract: Governments around the world have been targeting and killing individuals to prevent them from committing terror attacks or other atrocities. They use this method secretly, sometimes without even taking responsibility for such operations, and without making public most of the relevant information: who is being targeted and what are the criteria for targeting individuals, what evidence is used to make targeting decisions, and what procedures are adopted to identify mistakes or misuse of this method. Recently released documents, such as the U.S. Department of Justice Drone Memo (analyzing lethal operations against U.S. citizen Anwar Al-Aulaqi), the more general White Paper on targeted killings of US citizens, or the Report of the Israeli Special Investigatory Commission on the targeted killing of Salah Shehadeh, shed some light on otherwise highly secretive decision-making processes, thereby introducing to the public debate important information previously unavailable. At the same time, in revealing only a small amount of relevant information, they emphasize the thick veil of secrecy that still surrounds the discussions in this field. Moreover, the information that is available demonstrates the vague nature of the relevant rules; the security-oriented implementation of these rules; and the inadequacy of current oversight mechanisms of targeted killing operations. These challenges to a process designed to take human lives emphasize the need to develop effective and independent accountability mechanisms, with powers to investigate high-level policymakers as well as operational-level decision-makers. This policy-paper proposes concrete solutions to the main weaknesses of the current legal framework: it narrowly (and clearly) defines legal terms such as ‘imminent threat,’ ‘feasibility,’ and ‘last resort’; it develops an activity-based test for determinations on direct participation in hostilities; it designs an independent ex post review mechanism; and it calls for governmental transparency and meaningful oversight. Most importantly, it promotes a targeted killing policy that protects civilians from both terror and counter-terror attacks.

An Impact Evaluation of the Pacifying Police Units (UPPs)
BACKGROUND
Since 2008, Rio de Janeiro has implemented a new public security policy called the “Pacification”, a police strategy with full support from the Federal government that aims to improve the overall levels of security in the city and retake areas previously dominated by criminal organizations. Based on this new model of policing - that takes an approach on community policing initiatives – “Pacifying Police Units (UPPs)” are implemented in different poor communities in the city (shanty towns).
Self-Regulatory Lessons From the US Commercial Nuclear Power Industry: Why Does It Work and Why Can’t It Be Replicated?
-
Abstract: In the early morning hours of March 28, 1979, began a series of events that led to a partial meltdown of the reactor core at Unit 2 of the Three Mile Island nuclear plant and the worst accident in the history of the commercial nuclear power industry in the United States. Catalyzed by this event, the industry leadership formed an independent oversight entity, the Institute of Nuclear Power Operations, resourced its technical staffing, and ceded significant authorities to it in the areas of operational oversight, training and accreditation, the sharing of operational experience and provision of assistance to plants in need. As the former President and CEO of INPO, Admiral Ellis will discuss the requirements for effective self-regulation, specifically, and consider the issues surrounding broader employment of the concept.
About the Speaker: James O. Ellis Jr. is an Annenberg Distinguished Visiting Fellow at the Hoover Institution and a CISAC Affiliate. He retired as president and chief executive officer of the Institute of Nuclear Power Operations (INPO), a self-regulatory nonprofit located in Atlanta, Georgia, on May 18, 2012. In 2004, Admiral Ellis completed a thirty-nine-year US Navy career as commander of the United States Strategic Command. In this role, he was responsible for the global command and control of US strategic and space forces.
His sea service included carrier-based tours with three fighter squadrons and command of the USS Abraham Lincoln, a nuclear-powered aircraft carrier. His shore assignments included commander in chief, US Naval Forces, Europe, and Allied Forces, Southern Europe, where he led United States and NATO forces in combat and humanitarian operations during the 1999 Kosovo crisis.
Ellis holds two masters’ degrees in aerospace engineering and is a member of the National Academy of Engineering.
