Gapminder -Visualize Global Development Data

Byoliveridley

I must have been living in a cave somewhere to not have heard of this before today.

The Gapminder World 2006, beta

Gapminder is a non-profit venture that develops information technology for provision of free statistics in new visual and animated ways. In short, it enables you to make sense of the world by having fun with statistics. Our method is to turn boring data into enjoyable interactive animations using Flash technology. Gapminder is a Foundation in Stockholm, Sweden. Funding has been mainly by grants from Swedish International Development co-operation Agency, Sida. In collaboration with United Nations Statistic Division we promote free access to searchable public data and our animations of different types of data are freely available at www.gapminder.org.

The Pros
You have to take it for a test drive to see how cool it is, especially the animations to see how parameters like life expectancy, population, etc. change over time. You can pick countries to compare, or just scatter plot everyone. Look at Botswana’s life expectancy, for instance, see it peak in 1987 at 65 years and start a steep  plummet to 35 years in 2004 as its AIDS mass murder (epidemic is a word that does do this one justice) took hold. To watch the dot for life expectancy drop that quickly as you animate it is pretty powerful, as powerful as a statistic can be. Each parameter you change also changes the URL, so you can send links easily.

The Cons
You have to plot something against something else. Not everything is a scatter plot between two variables, you use it long enough, and you start seeing correlations (=causations!) where none exist. There’s no way to extract plots to use for later, though I guess you can do a screen capture.

Regardless, very cool, and nothing beats free access to large amounts of data that previously needed specialists to visualize and make sense of.

    He seems to write it himself, has comments and all, some of which aren’t very friendly. One of his posts talks about a Carbon ration card, meaning everyone starts off with a set of carbon credits, which you can either use, or sell back to the trading bank so that people who use more carbon can buy more.

    The principle is simple: there would be a decision about the nation’s
    annual level of carbon emissions, permits/quotas for that level would be issued on a per capital basis (probably for personal food, household energy and travel emissions), and those who spent under the wuota would be able to sell to those who spend above.

    Well put, and in classic blog style, no spellcheck!

    Meanwhile, in the US, we have the chair of the powerful Senate Committee on Environmental and Public Works and well known Global Warming denier.

    But coolness and hipness aside, it is refreshing for a minister (secretary, whatever you call them) to communicate in this fashion and be accepting of comments and criticism. We need a few more of these on the other side of the Atlantic (no,  not Antarctica, look West).

    An Ode to the Hummer? – Worst Column Ever

    Byoliveridley

    GM desperately needs an obnoxious, attention-grabbing brand to keep from turning into a dreary shadow of its former self. And America needs the Hummer to remind us of what has always made our automobiles stand out, from the tailfin 1950s to the muscle car 1960s and ’70s: swagger. Americans don’t just drive their cars — they proclaim something about themselves by driving them.It takes a certain kind of man — it’s almost always the owner of a Y chromosome — to take a gander at the Hummer, in all its broad, burly, paramilitary gas-guzzling glory, and see himself behind the wheel, striking fear and loathing in the hearts of ecologically sensitive motorists

    Matthew DeBord – Hummer, How We Need Thee – washingtonpost.com

    Yes, and we men need to beat our women and keep them pregnant all the time to avoid turning us men into dreary shadows of our former self.

    Seriously, this is the Washington Post, the newspaper of record of the capital city of the great United States, and this is not a satire. Way to paint the entire American male population as masculinity obsessed rageholics whose only aim is to strike fear in the heart of others while dressed in military fatigues. This man must possess an unhealthy degree of self-hatred to conclude  that disdain of a poorly designed, horrendously inefficient vehicle is somehow hippie and communist.This man is a disgrace to all mankind.

    This, on the other hand is satire…

    Ever since we changed our name from British Petroleum to BP (Beyond Petroleum) in 2000, we’ve led the way in developing progressive, environmentally friendly alternatives to gasoline. These last few years of pouring money into biofuels and renewable energy sources have been so great that I can’t for the life of me remember why we used to drill for dirty old oil in the first place! What’s that? You mean we’re still pumping that stuff from hundreds of refineries all over the world?

    Yes, when the Onion is better than the Washington Post, you know your country’s going to the dogs.

  • Coal is Evil, part 1201010

    Byoliveridley

    Note: When people say “clean coal”, they are referring in part to all the actions taken to limit particle and ash emissions out of the smokestacks. This is done in a variety of ways including washing the coal to remove inorganic ash components, trapping the particles using electrostatic precipitators, etc. What this leaves you with is very toxic coal ash, and very toxic acidified water loaded with the coal wastes it was used to remove.

    Now you can pretend that this is somehow cleaner, and it is, to an extent, because you have concentrated the pollution by isolating it and not letting it disperse into the atmosphere. However, if you then dump the waste into unlined landfills, you completely defeat the whole point of the exercise. This very extensive report written by the Clean Air Task Force and Earth Justice looked at streams in Pennsylvania and found a ton of heavy metal pollution.

    Coal is neither cheap, nor clean if you have to deal with all the pollution and pay for it, and we did not even have to get to that whole other pollutant, CO2!

    <Pennsylvania Groundwater Contaminated By Coal Ash

    Disposing of coal ash in mines is contaminating water supplies throughout Pennsylvania, according to a report released today by the advocacy group Clean Air Task Force and the nonprofit, public interest law firm Earthjustice.

    In 10 of 15 mines examined across the state, groundwater and streams near areas where coal ash, or coal combustion waste, was placed had levels of arsenic, lead, cadmium and selenium and other pollutants above safe standards.

    ‘Disposing of coal combustion waste in these mines is threatening water supplies all over the state,’ said Jeff Stant, director of the Pennsylvania Minefill Research Project at the Clean Air Task Force. ‘If the Pennsylvania Department of Environmental Protection won’t act now to stop these dangers, the U.S. EPA should step in to protect the residents of Pennsylvania who live near coal ash mine fills.’

    The Pennsylvania Department of Environmental Protection has refered to the ‘beneficial use’ of coal ash in these active and abandoned mines, claiming that the practice limits the outflow of acidic water from mines.

    This study found the opposite was true – in six of the nine permits that used coal ash to treat acid mine drainage, acidity levels increased, leaving the mines more acidic at the end of monitoring.

    PFOA emissions from Non stick cookware and Popcorn Bags

    Byoliveridley

    Important research coming out of NY. See here for previous PFOA posts. Perfluorinated compounds are used in the manufacture of Teflon, and are bioaccumulative. The theory is that the salts left over in the manufacture (residuals) are offgassing during use, and exposing consumers to bioaccumulative compounds.

    Cast Iron, anyone!!

    Quantitation of Gas-Phase Perfluoroalkyl Surfactants and Fluorotelomer Alcohols Released from Nonstick Cookware and Microwave Popcorn Bags

    Fluoropolymer dispersions are used for coating certain cookware products and food-contact packaging to impart oil and water repellency. Since salts of perfluorooctanoic acid (PFOA) are used as a processing aid in the manufacture of many fluoropolymers, it is necessary to determine if these compounds are still present as residuals after the process used to coat nonstick cookware or packaging, and could be released during typical cooking conditions. In this study, we identified and measured perfluoroalkyl carboxylates (PFCAs), particularly PFOA, and fluorotelomer alcohols (FTOHs; 6:2 FTOH and 8:2 FTOH), released from nonstick cookware into the gas phase under normal cooking temperatures (179 to 233 C surface temperature). PFOA was released into the gas phase at 7-337 ng (11-503 pg/cm2) per pan from four brands of nonstick frying pans. 6:2 FTOH and 8:2 FTOH were found in the gas phase of four brands of frying pans, and the sources of FTOHs released from nonstick cookware are under investigation. We observed a significant decrease in gas-phase PFOA following repeated use of one brand of pan, whereas the other brand did not show a significant reduction in PFOA release following multiple uses. PFOA was found at >5 ng during the fourth use of both brands of pans. FTOHs were not found after the second use of either brand of pans. PFOA was found at 5-34 ng in the vapors produced from a prepacked microwave popcorn bag. PFOA was not found in the vapors produced from plain white corn kernels popped in a polypropylene container. 6:2 FTOH and 8:2 FTOH were measured in the vapors produced from one brand of prepacked microwave popcorn at 223 ± 37 ng and 258 ± 36 ng per bag, respectively, but not measured at >20 ng (LOQ) in the other two brands. On the packaging surface of one brand of microwave popcorn several PFCAs, including C5-C12, 6:2 FTOH, and 8:2 FTOH, were found at concentrations in the order of 0.5-6.0 ng/cm2. This study suggests that residual PFOA is not completely removed during the fabrication process of the nonstick coating for cookware. They remain as residuals on the surface and may be off-gassed when heated at normal cooking temperatures.

  • “Boutique” Fuels still fashionable – EPA

    Byoliveridley

    So, when someone says something that is refuted rather indisputably by one of their agencies, maybe a retraction is in order? I won’t hold my breath, but this is good news. Region-specific pollution problems require and demand region-specific solutions. It is as “Boutique” as saying you have to vacuum a carpet and sweep a wooden floor. But, as we all know, the first step to vilifying something is to give it a French appellation.

    EPA: Special fuels not to blame for costs

    EPA: Special fuels not to blame for costs

    By H. JOSEF HEBERT, Associated Press WriterThu Jun 22, 4:38 PM ET

    “Boutique” gasoline blends to help states meet clean air rules are not a factor in higher prices as President Bush has suggested, says a draft of a study ordered by the White House.

    Although often cited as a reason for volatile gasoline prices, so-called “boutique fuels” have not caused unusual distribution problems or contributed to price increases, the report concludes.

    The review was conducted by a task force headed by the Environmental Protection Agency and involving representatives from the 50 states as well as the Energy and Agriculture departments.

  • Climate change infographic

    This infographic came my way via Learnstuff and it looked interesting. I have a love-hate relationship with infographics and this one evokes the same feelings of “I really appreciate the effort someone put into this and it looks great” vs. “how is this going to influence our policy makers, or create the intensity (read this link, it’s really good stuff by David Roberts of Grist) that is required to foster the system change we need”?
