A Song of Our Warming Planet

When faced with the challenge of sharing the latest climate change discoveries, scientists often rely on data graphics and technical illustrations. University of Minnesota undergrad Daniel Crawford came up with a completely different approach. He’s using his cello to communicate the latest climate science through music.

Thermometer measurements show the average global temperature has risen about 1.4 °F (0.8 °C) since 1880. Typically, this warming is illustrated visually with line plots or maps showing year-by-year changes in annual temperatures. As an alternative, Crawford used an approach called data sonification to convert global temperature records into a series of musical notes.

The final result, “A Song of Our Warming Planet,” came about following a conversation Crawford had with geography professor Scott St. George during an internship. St. George asked Crawford about the possibility of turning a set of data into music.

“Data visualizations are effective for some people, but they aren’t the best way to reach everyone,” says St. George. “Instead of giving people something to look at, Dan’s performance gives them something they can feel.”

Crawford based his composition on surface temperature data from NASA’s Goddard Institute of Space Studies. The temperature data were mapped over a range of three octaves, with the coldest year on record (–0.47 °C in 1909) set to the lowest note on the cello (open C). Each ascending halftone is equal to roughly 0.03°C of planetary warming.

In Crawford’s composition, each note represents a year, ordered from 1880 to 2012. The pitch reflects the average temperature of the planet relative to the 1951–80 base line. Low notes represent relatively cool years, while high notes signify relatively warm ones.

The result is a haunting sequence that traces the warming of our planet year by year since the late 19th century. During a run of cold years between the late 1800s and early 20th century, the cello is pushed towards the lower limit of its range. The piece moves into the mid-register to track the modest warming that occurred during the 1940s. As the sequence approaches the present, the cello reaches higher and higher notes, reflecting the string of warm years in the 1990s and 2000s.

Crawford hopes other researchers and artists will use or adapt his composition to support science outreach, and has released the score and sound files under a Creative Commons license.

“Climate scientists have a standard toolbox to communicate their data,” says Crawford. “We’re trying to add another tool to that toolbox, another way to communicate these ideas to people who might get more out of music than maps, graphs and numbers.”

The video ends with a stark message: Scientists predict the planet will warm by another 1.8 degrees Celsius (3.2 degrees Fahrenheit) by the end of this century. This additional warming would produce a series of notes beyond the range of human hearing.

Will young adults want Obamacare? Let’s ask a young person who’d know

Via WashPo

Via Ezra Klein at WashPo:

There’s been an interesting conversation over the last week about how young people will fare under health reform. Aaron Smith, executive director of Young Invincibles (and a bona fide young adult) has spent the past few years of his life worrying and working on exactly that question. So I asked him to weigh in. A lightly edited transcript of our conversation follows.

Aaron Smith: I’d begin with the economic landscape because I think that matters here. The young adults we’re talking about are largely low income. They might be in school or in school part-time or in community college. They’re in and out of the workforce. They’re having a tough time landing a steady job with benefits. They don’t make very much money. Many of them were on their parents’ plan growing up. They don’t have a ton of familiarity with the health system. They don’t always know what terms like “deductible” and “co-pay” mean.

But they know they can get sick. More young people than folks over 75 go to the emergency room in a year. It happens frequently enough to them and their friends that they know the costs can be astronomical. Young women are more frequent users of health care; they need things like birth control and regular check-ups. You have young men who don’t have a primary doctor or even remember the last time they went to the doctor. About 15 percent of young adults have a chronic condition and know pretty well that they need health care.

How many of them are uninsured now?

About 19 million young adults 18 to 34 lack health insurance. Our polling shows that less than 5 percent of young people choose not to have it. The number one reason they don’t have it is the cost. Most young people don’t qualify for Medicaid right now even if they have very low incomes because most states just don’t give childless adults Medicaid. That’s one of the biggest changes under Obamacare. If every state expanded Medicaid, about 8 million would qualify for Medicaid. Another 9 million would qualify for subsidies because they make less than 400 percent of poverty.

So then 17 of the 19 million uninsured young people are, in theory, eligible for either subsidies or Medicaid under Obamacare?

That’s right. It’s a pretty phenomenal percentage. So if we do our jobs right, young people will be one of the biggest winners in the health-care law.

But behind this conversation lurks this larger question of whether young people care about health insurance at all. There’s a school of thought that says a lot of the young people who are uninsured or have very little insurance just don’t think they need health insurance. But, and this is anecdotal, that doesn’t fit with my experience very well. Young people I know are really nervous when they don’t have health insurance. They’re really excited if they get a job with benefits. I’m not saying I’ve got a perfectly representative sample, but I’m just not meeting many of these kids who literally don’t care about being insured. 

I heard this story on the radio the other day about a young person who said, “I didn’t really feel like I was an adult until I got a job with health insurance.” That’s definitely something I can relate to and that I’ve seen out there in the field. The term “young invincibles” is a health insurance industry term. It tries to explain the fact that young people are disproportionately uninsured. But I think people just dramatically underestimate how hard it is for someone who don’t get health insurance at their job to get health insurance. Less than 50 percent of young adults get employer-sponsored health insurance.

There have been some studies that looked at the choice of whether to accept coverage when you had an employer-based offer. Young people and older people made pretty much the same decisions. Older people were a bit higher, but both were above 70 percent. So when they have the option, the vast majority take it. But when you don’t have the option you have to make tough choices. It’s like deciding not to have a car or living in a bad area. It’s just a tough choice.

 But the cost does matter. So is Obamacare actually going to make insurance affordable for this group? Or will it make insurance more expensive for young, healthy people by making it easier for sicker, older people to buy insurance without getting discriminated against? 

The first important point is the huge percentage of unemployed young people who get access to either subsidies or Medicaid. So you saw in California that many young people will end up having insurance options that cost them less than $100 or less than $50 simply because their income is low enough to qualify for subsidies. For someone making $20,000 a year, they’re going to have to pay $40 a month for health insurance. That’s a very good deal. And in a state like California, there are also millions of young people who qualify for Medicaid.

Now we’ve identified a population between 300 percent and 400 percent of the federal poverty level that’s going to have more problems. The subsidies aren’t that rich for them, and so whether to buy is a tougher question. They’ll have financial strain. They have financial strain now. That’s why they’re uninsured. If you’re just getting by, then $200 a month can be a lot. That’s where education can be key. It can still make good financial sense to be covered because there are real risks. But I think, in general, it will be a good enough deal to sign up. We saw that in Massachusetts where youth uninsurance dropped in half in the first year.

 Expand on that a bit. I recognize Massachusetts is a somewhat unusual state. But its health reforms were very similar to the national reforms. They should’ve had the same issues with rate shock and with bringing older and sicker people in. So what did we learn from them?

There were a couple of interesting things in Massachusetts. One is the Massachusetts exchange had what’s called the “young adult” plan. It’s higher deductibles. It’s a bit cheaper in terms of premiums. It’s similar in some ways to the catastrophic plan available under the health-care law. It’s the most popular plan for young adults in the exchange. So that’s one important point: Youth-tailored insurance options are important.

And just to be clear, the federal plan has something similar in this catastrophic plan mainly available to young people, right? 

Yes, so there’s a catastrophic plan as part of the health law. There’s not been that much analysis of it. But it’s specifically targeting that young adult population. It has a very high deductible — about $6,000. So it’s not generous coverage. But it meets all the other standards in terms of benefit caps and preventive coverage and no discrimination and so on. For many young people, that will be their cheapest option. Particularly above that 300 percent of poverty line. In California, that was costing about $130 to $150 a month.

What else did we see in Massachusetts? 

They also did big public outreach campaigns. They got the Boston Red Sox to do PSAs. They understood there had to be an attitude change and they were very proactive about trying to address it. The polls show health reform in Massachusetts is actually quite popular, even among young people who are now being forced to purchase coverage. And that’s another similarity. There’s a mandate. But it has exceptions. Not many people pay it in Massachusetts. If you’re low-income, it doesn’t apply to you. That’s true nationally, too. The mandate doesn’t apply to you if coverage is more than 8 percent of your income. What we saw in Massachusetts is that people are either exempt or they choose to pay for health insurance, Very few end up paying the mandate.

The last point which has been talked about so much people don’t think about it anymore is the expansion of dependent coverage which has also been very popular. Nationally about three million people are estimated to have gotten back on their parents plan because of the law.

 So given all the issues of implementation and the political opposition to the law and the difficulties in various states and the early information about premiums, where do you think this will end up in 2014 and 2015? Do you think young people will sign up or stay away?

I’m pretty hopeful, in part because the experience in Massachusetts showed this model can work. But it will play out differently in different states. A state like California is following the playbook. They’ll do a big promotional campaign. They’re investing in on-the-ground outreach and education. They’re expanding Medicaid so really low-income folks will qualify for health insurance. So I could see it being a huge success in a state like that. But not every state will do that. An important point for young people is that some of the states with the highest rates of youth uninsurance are in the south and some of those states aren’t expanding Medicaid or building their own exchanges. My fear is what happens in those states. So I could see some states coming out and looking much better than other states.

Climate Change is Real: This is Not Deja Vu

Rather than repeat myself too much, I’ll just cite another meta-study that shows conclusively that “an overwhelming 97 percent of climatologists endorse the idea of human-caused global warming“.

Some fun quotable highlights:

When asked if he believed in man-made global warming in April, Mayor Rex Parris of Lancaster, California, responded: “I may be a Republican. I’m not an idiot.”

“There is a divide within the party,” Samuel Thernstrom, an environmental policy scholar who served on President George W. Bush’s Council on Environmental Quality, told National Journal earlier this month. “The position that climate change is a hoax is untenable.” (Emphasis mine)

TED Talks: The Economic Case for Preschool


In this well-argued talk, Timothy Bartik makes the macro-economic case for preschool education — and explains why you should be happy to invest in it, even if you don’t have kids that age (or kids at all). The economic benefits of well-educated kids, it turns out, go well beyond the altruistic. (Filmed atTEDxMiamiUniversity.)

The author of “Investing in Kids,” Timothy Bartik studies state and local economies — and analyzes the benefits of preschool as an economic development program.

RSAnimate: 21st Century Enlightenment

The RSA’s Chief Executive Matthew Taylor explores the meaning of the RSA’s strapline ’21st Century Enlightenment’. How might this idea might help us meet the challenges the world faces today, and what role can be played by organizations such as the RSA?

The RSA is a charity dedicated to finding innovative, practical solutions to today’s social challenges. Through its ideas, research and 27,000-strong Fellowship it seeks to understand and enhance human capability so we can close the gap between today’s reality and people’s hopes for a better world.
