“Norway pledges $300 million/year to green world’s power”

Norway recently announced a new program to fund renewable energy and carbon mitigation programs in developing nations. The Energy+ Partnership unites several developed countries in an effort to provide universal access to energy while cutting emissions from global energy production. Norway has pledged NOK 1.8 billion ($300 million) to the effort, which is set to launch in June of this year. Investments are “results based”: recipient countries are required to demonstrate increasing public access to energy and decreasing overall emissions. Energy+ builds on the success of Norway’s REDD+, an initiative for reducing emissions from deforestation and forest degradation in developing countries.

 

Countries and organizations currently partnered (or committed to becoming partners) include: Kenya, Bhutan, Liberia, Ethiopia, Maldives, United Kingdom, Switzerland, France, the World Bank Group, Asian Development Bank, African Development Bank, United Nations Industrial Development Organisation, United Nations Development Programme, United Nations Environment Programme, International Energy Agency, World Business Council on Sustainable Development, Global Village Energy Partnership, United Nations Foundation.

Nature Magazine: “Pollutants key to climate fix”

This article from Nature Magazine presents a comprehensive review of several recent studies highlighting the importance of mitigating methane and soot emissions. Most recently, Science Magazine commented on the this subject in the article “Simultaneously Mitigating Near-Term Climate Change and Improving Human Health and Food Security.” This article interviews co-author Veerabhadran Ramanathan. “We’re in a gridlock over carbon dioxide, and we’re losing time,” notes Veerabhadran Ramanathan. “This is one way to buy back some of that time, and the co-benefits are huge.”

 

The article also presents the United Nations Environment Programme’s (UNEP) contributions to this topic. In a publication released last June, the UNEP analyzed hundreds of options for reducing soot (“black carbon”) and ozone emissions, and ranked them according to their potential for total climate impact. For methane, the UNEP targeted 14 measures across the coal, oil, landfill, wastewater, livestock, and rice industries.

 

Although the benefits of reducing methane and soot emissions are clear, the article highlights the need to remain committed to long-term CO2 reductions. Kevin Trenberth, climate scientist at the National Center for Atmospheric Research in Boulder, Colorado, is quoted as warning against decreased attention to CO2 levels: “The fundamental problem with long-term climate change is CO2, and anything that takes us away from addressing that doesn’t really solve the problem,” he says. “It just puts it off.” (January 17, 2011)

“China set to launch first caps on CO2 emissions”

Beijing has recently asked five cities and two provinces to set emissions caps in anticipation of China’s forthcoming regional carbon trading scheme. The cities of Beijing, Shanghai, Tianjin, Chongqing, and Shenzhen, as well as the provinces of Hubei and Guangdong will participate. The trading scheme will not place a cap on overall carbon emissions, but rather carbon intensity. Carbon intensity refers to the amount of greenhouse gasses emitted per unit of GDP. This relative measure of carbon emissions is considered a more development-friendly approach to curbing emissions. China’s current plan, beginning in 2011 and culminating in 2015, targets overall carbon intensity reductions of 17 percent.  (January 17, 2012)

China’s Premier Discusses Energy Plans

Chinese Premier Wen Jiabao’s outlined China’s commitments to carbon reductions in a recent speech given at the World Future Energy Summit in Abu Dhabi. The speech drew attention to the rapid rate of urbanization in China, and the energy-demand implications of this development. Jiabao noted that China is expecting vast surges in energy demand as the country continues to urbanize. To prepare for this increase in demand, Jiabao focused on the need for a diversified energy supply, as well as advancements in transmission and efficiency. He also reaffirmed China’s commitment to research and development of advanced clean technologies. (January 20, 2012)

“European Offshore Wind Industry Key 2011 Trends and Statistics”

The European Wind Energy Association recently released its 2011 report The European Offshore Wind Industry Key 2011 Trends and Statistics. The report describes the major developments in European offshore capacity in 2011. The following chart describes the key findings of the report with regard to installed and total capacity in 2011.

 

  Quantity of turbines (#) Total output (MW)
New 2011 (grid connected) 235 1,371
Total 2011 1,371 3,813

 

 

In terms of future outlook, the report describes nine projects currently underway that will increase capacity by a further 2,375 MW once completed. The EWEA’s target for installed EU offshore wind power capacity by 2020 is 40,000 MW, producing approximately 4% of the EU’s total electricity consumption.

 

Justin Wilkes, Policy Director of EWEA, noted that “[d]espite the economy-wide financial squeeze, 2011 saw a 40 per cent increase on the previous year in offshore non-recourse debt financing, up from 1.46 billion Euros in 2010 to 2.05 billion Euros in 2011.” He continued: “[t]he strong project pipeline and financial developments highlight the importance of countries continuing to provide and develop stable long-term frameworks for offshore wind power in order to allow the industry to continue its development.” (January 20, 2011)

“Study: 95% Of All Trips Could Be Made By [Electric Vehicles]”

A recent study by two doctoral students at Columbia University found that electric vehicles could make approximately 95% of all single-destination trips. The study used data from a 2009 National Household Travel survey, and found that only about 1% of all single-destination trips covered distances greater than 70 miles. The data also suggested that about 95% of all such trips were less than 30 miles in length. The authors  – Garret Fitzgerald and Rob van Haaren – calculated the average commute of American workers at 13.6 miles.  (January 17, 2011)

“Apps4Africa: Winners In East Africa Contest”

Apps4Africa: Climate Change recently announced the winners of its 2011 East Africa contest.[2] The first place prize went to the Grainy Bunch, from Tanzania. The Grainy Bunch is a national grain supply chain management system that monitors the purchase, storage, distribution, and consumption of grain across Tanzania. It was developed with the idea that selling “the effects of efficiency” to actors in the grain supply chain is much easier than selling “the effects of climate change”.

 

The second place prize went to Mkulima Bora of Kenya. Mkulima Bora is an application that allows farmers to predict crop yields for a given location and time of year. It does this by cross-referencing the farmer’s input of crop type with meteorological data. Third place went to Agro Universe of Uganda. Agro Universe provides a regional agriculture and livestock marketplace. The mobile and web-based application connects buyers and sellers of agriculture and livestock. (January 23, 2012)

Online Education

by RBLAMANNA

This is a fantastic blog post from Felix Salmonat Reuters. It describes Sebastian Thrun’s (of Stanford University) recent experiment with an entirely online and entirely free course Introduction to Artificial Intelligence. Anyone could take the course, and ultimately 160,000 people did. About 250 students got perfect scores. Of those 250, not a single was enrolled at Stanford!

Udacity and the future of online universities

January 23, 2012 @ 12:32 pm

By Felix Salmon

The most exciting (but also, in a small way, slightly depressing) presentation at DLD this year came from Sebastian Thrun, of Stanford and Google. Or formerly of Stanford, anyway.

Thrun told the story of his Introduction to Artificial Intelligence [1] class, which ran from October to December last year. It started as a way of putting his Stanford course online — he was going to teach the whole thing, for free, to anybody in the world who wanted it. With quizzes and grades and a final certificate, in parallel with the in-person course he was giving his Stanford undergrad students. He sent out one email to announce the class, and from that one email there was ultimately an enrollment of 160,000 students. Thrun scrambled to put together a website which could scale and support that enrollment, and succeeded spectacularly well.

Just a couple of datapoints from Thrun’s talk: there were more students in his course from Lithuania alone than there are students at Stanford altogether. There were students in Afghanistan, exfiltrating war zones to grab an hour of connectivity to finish the homework assignments. There were single mothers keeping the faith and staying with the course even as their families were being hit by tragedy. And when it finished, thousands of students around the world were educated and inspired. Some 248 of them, in total, got a perfect score: they never got a single question wrong, over the entire course of the class. All 248 took the course online; not one was enrolled at Stanford.

Thrun was eloquent on the subject of how he realized that he had been running “weeder” classes, designed to be tough and make students fail and make himself, the professor, look good. Going forwards, he said, he wanted to learn from Khan Academy and build courses designed to make as many students as possible succeed — by revisiting classes and tests as many times as necessary until they really master the material.

And I loved as well his story of the physical class at Stanford, which dwindled from 200 students to 30 students because the online course was more intimate and better at teaching than the real-world course on which it was based.

So what I was expecting was an announcement from Thrun that he was helping to reinvent university education: that he was moving all his Stanford courses online, that the physical class would be a space for students to get more personalized help. No more lecturing: instead, the classes would be taken on the students’ own time, and the job of the real-world professor would be to answer questions from kids paying $30,000 for their education.

But that’s not the announcement that Thrun gave. Instead, he said, he concluded that “I can’t teach at Stanford again.” He’s given up his tenure at Stanford, and he’s starteda new online university called Udacity [2]. He wants to enroll 500,000 students for his first course, on how to build a search engine — and of course it’s all going to be free.

Udacity looks great, and I can’t wait for it to be a revolutionary success, educating and empowering students around the world, especially in places like Africa and India, and, in those places, especially women.

But I have to say I’m a little sad that it’s happening away from, rather than being part of, Stanford. If any world-class university would embrace this idea, one would hope it would be the one at the heart of Silicon Valley. And surely Udacity would only benefit if it was part of Stanford and carried the Stanford brand name. Instead, Thrun is abandoning Stanford and creating Udacity on its own. (And I’m no great fan of the name, either.)

Stanford was willing to spend hundreds of millions of dollars building a new physical campus in New York City — but it isn’t willing, it seems, to help Thrun build a free virtual campus which could reach the whole world. That’s a dereliction of its educational duty. But where Stanford has failed, surely some other elite university will step in. Thrun is taking a bold step here. Let’s hope he soon gets the support, if not of Stanford, then of some other college. Like Harvard, or Yale, or Oxford, or Cambridge. They’re exclusive places now. But they don’t have to be, in the future.

Scientists say cut soot, methane to curb warming

A recent study published in the journal Science argues that scientists and policy-makers should refocus their attention on methane and soot in their efforts to curb global warming. In short, they argue that curbing methane and soot emissions are a more practical “quick-fix,” and focusing on them can free-up capital for more long-term solutions to carbon reduction.

 

Methane comes primarily from landfills, farms, drilling for natural gas, and coal mining. Soot, called black carbon by scientists, is a byproduct of burning and comes primarily from cook stoves using wood, dung and coal in developing countries and in some diesel fuels worldwide. Carbon dioxide is still considered the lead contributor to global warming, accounting for 48 percent of the phenomenon, while soot contributes 16 percent, and methane contributes 14 percent.  Importantly, however, a molecule of methane or soot causes substantially more warming then a carbon dioxide molecule over a 20-year period. If certain measures were adopted, the scientists calculate that would reduce projected global warming by 0.9 degrees Fahrenheit (0.5 degrees Celsius) by the year 2050. Without the measures, global average temperature is projected to rise nearly 2.2 degrees Fahrenheit (1.2 degrees Celsius) in the next four decades.

Understanding Consciousness

by J Arett

A great TED talk by Antonio Damasio about the biology of consciousness.  He is right to state that understanding consciousness is incredibly important for understanding society and culture, and I am here to emphasize it is important for understanding aspects of our legal system.  Obviously the most important implications would come for criminal law, but I think his talk also touches on the important implications for animal law.  It seems more and more we are discovering that animals are not as different from us as we once thought.

Every time I read about a new discovery regarding consciousness, I am amazed at how little we understand about ourselves.  With new brain imaging technology and better computer processing power, hopefully a truly better understanding of one of life’s most basic questions will come to pass.

Are boys better at math? Larry Summers’ comment is finally debunked

by J Arett

In 2005, Larry Summers infamously gave a talk about the reasons there are fewer women in the highest echelons of math and science.  In it, he stated, ”In the special case of science and engineering, there are issues of intrinsic aptitude, and particularly of the variability of aptitude, and that those considerations are reinforced by what are in fact lesser factors involving socialization and continuing discrimination.”

While numerous academics have chiseled away at the “intrinsic aptitude” theory, a new study by Jonathan Kane and Janet Mertz entitled, “Debunking Myths About Gender and Mathematics Performance” has finally put it to rest.  In fact, the article finds that the gender gap is entirely caused by those “lesser factors.”  Here is a great article summarizing the findings.

In my opinion the most important aspect of the paper is the finding that both boys and girls do better in math in a society where there is greater equality.  This makes sense intuitively, because when women are equally educated and earn equal pay their children will do better.  This finding is extremely important, as it contradicts those that see advancing the welfare of women as a “female problem.”  This is just another piece of evidence to demonstrate that when women are treated equally, we all benefit.

Now if only someone would do a study that finds women also aren’t intrinsically better at cleaning and taking care of children, we might actually get somewhere.

“Durban and everything that matters”

This Economist article reviews the recent Durban agreements, and aggregates the coverage from several reputable sources. The Financial Times appear optimistic. “Finally the world agreed that every country, no matter how rich or poor, would cut its greenhouse gas emissions under a global pact with ‘legal force’.” The Council of Foreign Relations had a more measured reaction. Michael Levi notes that the ultimate agreement – “a process to develop a protocol, another legal instrument or an outcome with legal force under the Convention applicable to all Parties” – might refer to almost anything, regardless of its impact on Climate Change. David Roberts from Grist.org is similarly pessimistic. His report on the talks highlights the indeterminate and relatively non-binding nature of the promise to develop an agreement by 2015.

Interview with Daniel Kahneman – “Thinking about thinking”

by robert lamanna

This is an interview  of Daniel Kahneman by Sam Harris. It’s about his latest book, Thinking, Fast and Slow - Kahneman’s first for the general public. The book synthesizes much of Kahneman’s work on heuristics and biases, decision making, and differences between the “experiencing self” and the “remembering self.” The interview probes Kahneman’s thoughts on what his research has to say for human well-being and how to improve it.

Thinking about Thinking

An Interview with Daniel Kahneman

Daniel Kahneman is an extraordinarily interesting thinker. As a psychologist, he received the 2002 Nobel Prize in Economics for his work with Amos Tversky on decision-making. Here is what Steven Pinker, my previous interview subject, recently wrote about him:

Why asking for more gets you less…if you’re a woman; Paper on “The Social Incentives for Gender Differences in the Propensity to Initiate Negotiations”

by robert lamanna

A previous post on this site (see below) discussed how women were far less likely to negotiate for salary increases. That post concluded that, at least to some extent, the squeaky wheel gets the olive oil. Past studies show that women are more likely to be modest. And they also show that self-promotion, not modesty, leads to perceived competence. So why not just abandon modesty and claim riches?

This paper by Hannah Bowles, Linda Babcock, and Lei Lai explains shows that there’s a very good reason women shy away from negotiation and self-promotion: they are socially penalized if they do.

Here are are the Discussion and Conclusions portions of the paper: (Or click here for the full paper.)

We posed the question at the beginning of this paper of whether women’s greater reluctance (as compared to men) to initiate negotiations over resources, such as higher compensation, could be explained by the differential treatment of male and female negotiators.

Neuroscientists can now predict the severity of psychosis. Does this affect the law?

by robertgreer

Researchers in the U.K. are claiming they can use functional MRIs and computer algorithms to predict whether patients will suffer from continuous psychosis (which is normally considered to require institutionalization) or episodic psychosis (which is not).  They claim a prediction accuracy of around 70%, while the legal standard for involuntary commitment to a mental institution is merely preponderance of the evidence.  Does this mean that courts should allow the use of this technique (or perhaps even compel it) when making involuntary commitment rulings?

“Pope, Tutu urge climate-change deal”

Pope Benedict XVI and Rowan Williams, the Archbishop of Canterbury, called on world leaders to meaningfully address climate change at the coming negotiations in Durban. Pope Benedict told Romans that he “hope[s] all members of the international community will agree on a responsible, credible and united response to this worrying and complex phenomenon.” Rowan Williams urged leaders to show “real moral leadership.” He also urged rich nations to clearly detail how pledges for the Green Climate Fund will be fulfilled. Nobel Peace laureate Desmond Tutu called climate change a “huge, huge enemy” and noted how “no country can fight that enemy on his own.” (November 28, 2011)

“At Meeting on Climate Change, Urgent Issues but Low Expectations”

This New York Times article begins, “[w]ith intensifying climate disasters and global economic turmoil as the backdrop, delegates from 194 nations will gather in Durban, South Africa, starting Monday to try to advance, if only incrementally, the world’s response to dangerous climate change.” The article addresses the “monotonously familiar” negotiation process of international climate negotiations, but notes that the process is being internally criticized. Poorer nations risk being marginalized at the negotiations, and are keen to establish a meaningful presence at the meetings. The article also addresses the Kyoto Protocol issue, namely whether the international community will agree to extend the agreement. (November 27, 2011)
