Scientists Baffled By Unknown Source of Ozone-Depleting Chemical

schwit1 writes: Scientists have found that, despite a complete ban since 2007, ozone-depleting chemicals are still being pumped into the atmosphere from some unknown source. "Carbon tetrachloride (CCl4), which was once used in applications such as dry cleaning and as a fire-extinguishing agent, was regulated in 1987 under the Montreal Protocol along with other chlorofluorocarbons that destroy ozone and contribute to the ozone hole over Antarctica. Parties to the Montreal Protocol reported zero new CCl4 emissions between 2007-2012. However, the new research shows worldwide emissions of CCl4 average 39 kilotons (about 43,000 U.S. tons) per year, approximately 30 percent of peak emissions prior to the international treaty going into effect. "We are not supposed to be seeing this at all," said Qing Liang, an atmospheric scientist at NASA's Goddard Space Flight Center in Greenbelt, Maryland, and lead author of the study published online in the Aug. 18 issue of Geophysical Research Letters, a journal of the American Geophysical Union. "It is now apparent there are either unidentified industrial leakages, large emissions from contaminated sites, or unknown CCl4 sources."

    I know because it's happening all over the Coachella Valley. I have seen cut rate guys NOT reclaiming or pumping down coils - jettisoning 10+ pounds each time. This occurs at least 50 times a day here in the desert that I know of. Even top paid contractors like callthegeneral.com just don't care because their commission is based on number of visits per day, and it takes an extra 15-25 minutes to pump a system down before removal. The wholesale houses even pay a couple $$$ per pound of the reclaimed stuff, but commission rates ensure blowing off straight to atmosphere every time.

    Who else would, unapologetically, give the middle finger to the environment?

    Brazil, Mexico, Spain, Turkey, Egypt, Pakistan, US, UK, Sweden, Argentina, Australia, South Africa, Nigeria, Poland, and probably quite a few others.

    But not Canada. Canada would apologize.

    Can we just agree on greed being the culprit? Democrat, Republican, where's the difference? As long as there's money to be made by ignoring the law and as long as breaking a law and getting caught is cheaper than heeding it, greed trumps "doing the right thing" any time.

    I can think of a certain group of American Republicans who would do exactly that...

    Privately there are many Republicans that do believe in the scientific method and would like to see action on climate change but are reluctant to admit it because of fear of being labeled as traitors. On the Democratic camp there are many that realize that cap and trade, and so called "renewables" cannot be a complete solution to halting global warming but are simply afraid to support low or 0 carbon, but uncool power generation technologies, such as Nuclear for fear of being labeled the same.

    So just because a bill is called the Clear Skies Act, you think it helps the environment and hurts corporations? Apparently you're the reason that consultants like Frank Luntz make the big bucks. My friend worked for him when he came up with that name. It was a total giveaway to corporate interests. That does nothing to contradict my post.

    Nixon was much more centrist and pragmatic on a lot of issues than people remember. Also, that EPA bill was passed by a Democratic Congress. The GOP really started their anti-environment push with Reagan- who immediately had the solar panels removed from the White House. It went into high gear starting in 1994 with Newt Gingrich.

    The Government is basically the worst possible nightmare-scenario giant monopoly evil corporation you can imagine.

    Here in the UK, our government has taken steps to prevent there being a monopoly ISP. They didn't start a government-run ISP, they just regulated things to prevent a monopoly. And... it worked. Not all government intervention means shifting things from the private to the public sector. If anything, I imagine there are now more ISP jobs than there would be with a monopoly.

    Also, we don't have to suffer truly godawful ISPs, the way you do in the US, which is nice.

    But no, you'll go on believing all that government does is evil (that might not be such a worry if it weren't for that your system allows payments that would be classified as bribery in damn near any other country, btw), and that there's no better way to run a country than by letting corporations screw over the average person.
