The compound nitrogen trifluoride (NF3) is a "missing
greenhouse gas" that may have an impact 17,000 times as great as carbon
dioxide, according to a new study by atmospheric chemist Michael Prather, published
in the journal Geophysical Research Letters on June 26.
The compound is used in the production of Liquid Crystal Display (LCD) Panels,
in semiconductors, and in synthetic diamonds. According to Prather, the
compound was initially missed by the Kyoto Protocol, the international treaty
governing response to global warming, due to the fact that it was not widely
used at the time.
The Kyoto protocol covered six gases, and nitrogen trifluoride was noticeably
absent. Since that time, production of the compound has grown at a
frenzied pace due to the proliferation of LCD panels in phones, TVs, and
computer screens. More semiconductors are also using the compound. According
to Pranther, global production may double in 2009, to 8,000 metric tons.
The treaty left out about a dozen gases that technically were greenhouse gases,
but were not manufactured in sufficient quantities to have an impact.
Perfluorocarbons (PFCs) and of sulfur hexafluoride, which were considered,
actually are projected to have less effect this year than the nitrogen
The amount of nitrogen nitrofluoride emissions is expected to total this year
to approximately the emissions of a smaller industrialized nation, such as
Austria in CO2, the equivalent of about 67 million metric tons
The Kyoto Treaty's failure to consider changes in industrial use may come back
to haunt it. Particularly ironic is that the chemical was touted as a way
to prevent global warming. Since flat-panel TVs consume less power than
rear project or plasma models, they were
presented as environmentally friendly.
In reality when the LCD market hits full swing, as is expected with the 2009
switch to digital television, the increased production will send levels of this
new greenhouse gas soaring. Worse yet, with 80 million analog
TVs projected to be discarded by Americans in the shift, some older LCD
models, more of the gas and other hazardous chemicals may be released if
they're disposed of improperly and merely tossed in landfills or incinerated.
Another piece of bad news is that the gas has a very long half-life -- staying
in the atmosphere for approximately 550 years, with almost no ecological cycles
to aid in its removal.
While carbon dioxide emissions remain a pressing issue, soon we may be hearing
a lot more about nitrogen trifluoride if the study's conclusions hold true.
quote: Yeah, you mean like that $300B in global aid we gave, while we sit in the midst of a recession and changing our own lifestyles to cope with the risings costs of fuel and food?
quote: Wrong on a few counts. First of all, you're using a highly misleading metric that measures not total giving, but rather share of GDP.
quote: Secondly and much worse, you're ignoring by far the largest portion of US giving -- private contributions. The US has by far the largest amount of private contributions of any nation on earth, a sum which far outweighs governmental aid.
quote: $253 billion in gifts supported more than 1.4 million charities including religious congregations, schools, clinics, arts groups, food banks, and more.
quote: Nonetheless, the median estimate was 20% of the federal budget, 20 times the actual amount of approximately 1%
quote: OverestimationThe feeling that the US spends too much on foreign aid seems to rest on an extreme overestimation of how much the US government spends on foreign aid. PIPA's July 2000 poll asked respondents to estimate how much of the federal budget goes to foreign aid. They were told that they could answer in fractions of a percent as well as whole percentage points, thus implying that the amount could be quite low. Nonetheless, the median estimate was 20% of the federal budget, 20 times the actual amount of approximately 1%.
quote: when respondents were asked "to imagine the US economy and the European Union economy as if they were one big economy," and then to think about the relative shares of development aid to poor countries given by the US and Europe, the median respondent estimated that the US gives 60% and the European Union 40% (PIPA, February-April 1998). When asked what they thought it should be, the median respondent wanted a 50-50 split, with the US and Europe sharing the burden equally. (In reality, based on 1996 figures from the OECD, the US gave only 22% while the EU countries gave 78%.)

quote: Which kinda proves my point... we're so lost in our own ego that when someone dares say we're not 100% perfect as a country, our reaction is to point out that everyone else is still farther away from 100% than we are instead of discussing actual options and solutions to fix the problem.

quote: The latest consensus from a survey of thousands of scientists is that they don't believe there is global warming.
quote: If you had read the article from epw.senate.gov closely, you would have noticed that the survey of scientific papers from 2004-7 revealed that, while 45% of scientists implicitly endorsed the theory that global warming is human-made, 48% are neutral (agnostic?). This hardly supports your assertion that scientists "don't believe there is global warming."
quote: True, however the vast majority of papers in the 'believers' category included those which only implicitly accepted the theory, meaning many (or few) of them may not believe in it.
quote: Furthermore, all one needed to register in the believers column was acceptance of global warming itself, not man-made global warming. Meaning the number of believers in anthropogenic warming is smaller still.
quote: I was mistaken. Nevertheless, my original post is still correct in stating that the poster to whom I was replying was inaccurate in his assertion that scientists do not believe in the theory of global warming
quote: Rather more precisely, he should have said "the published research of a majority of scientists does not support anthropogenic global warming".
quote: When someone says, for example, "I don't believe in god", most people, regardless of the logical fallacy you hilight, assume the speaker is an atheist. If the speaker were an agnostic, we would assume he would say so, as to prevent any ambiguity

quote: Don't even begin to tell me you can't haul a lot of stuff in a Sienna van. You can - my wife's family owns one and it can haul a ton.
quote: As far as safety - sure, you can increase the safety of the vehicles, and argue that they have been getting better, but you fail to miss the point.
quote: We aren't talking about the safety per-say of the SUV itself. We are talking to the safety in relation to the cars on the road.
quote: A smaller car with a lower center of gravity will react far better than an SUV at high speeds, thus allowing the smaller car a greater chance to:a. evade dangerb. present less danger to othersc. stop faster (not COG related, but weight related)

quote: The SUV's might be safer to the occupants inside, but they are not safer to those around them if driven irresponsibly.
quote: So we have higher weight
quote: higher center of gravity
quote: increased suspension travel
quote: increased body roll

quote: Do you really believe everything said up to today about the planet's deteriorating environmental status and our involvement in that process has been "GW & liberalism crap" and propaganda?
quote: It's really just a mechanism to undermine capitalism and allow the rich to get richer and the poor to pretty much stay where they are.
quote: Even if the idea of global warming had ZERO merit, the cost of energy should be causing us to find alternate solutions.
quote: I don't think anyone would ever dispute that. People are just fed up with this alarmist GW crap. Those people just want to make headlines, science later.
quote: The reason why these alarmist headlines exist is because people chose to ignore the warnings in the first place because they saw no immediate effects
quote: If people on the opposing/status quo side were more willing to have discourse on the issue, and sponsor honest studies (honest toward both sides, as both sides have obscured the truth in one way or another), you would probably see a lot less of this "alarmist crap" coming from the "liberal propagandists".
quote: and more forward looking analysts warned against the Fed continually lowering the interest rate to such low levels. They simply ignored it.
quote: Now, if manufacturers had done proper research on how their manufacturing processes affect the environment, environmentalists wouldn't have to dig this crap up on their own.
quote: No, global warming is not 100% proven, but there's more evidence showing it is occurring- and even more evidence pointing to the idea that man exacerbating the warming effect. And if climate shift does occur, it will affect everyone.
quote: You can believe in your simple faith, but I think that scientists are telling a much more complex story than you are willing to accept.

quote: Modern convenience already has bitten the US economically.
quote: But no, lets just call it unfounded propaganda
quote: I guess I'll have to repeat my "read for context" comment again.
quote: My whole point was about the idea of just citing things as unfounded propaganda.
quote: I'm not even going to address the wealth issue you brought up because it's meaningless and has nothing to do with anything I said.We're doing the same thing with GW by letting our consumerist urges and wants dictate our actions. Even if it doesn't hurt us ecologically, it's beginning to hurt us economically.
quote: Don't go off making unrelated points.
quote: I stuck only to the economic points you made.
quote: No, you expanded the point out into the wealth of other nations compared to ours
quote: but I will say that people who had confidence in our economy expected (read as: wanted) this downturn to be over by now.
quote: but you cannot deny that even if this is cyclical, decisions made within the economic markets has hurt everyone substantially.
quote: Apparently, false confidence can be harmful just like FUD.
quote: AN INDUSTRIAL chemical being used in ever larger quantities to make flat-screen TVs may be making global warming worse.
quote: Most climatologists say it's caused by excessive CO2 gasses being released due to the burning of fossil fuels.
quote: Those companies that make profits by selling fossil fuels say it's either caused by natural forces or it's just a figment of everyone's imagination and they shouldn't worry about it.
quote: A six-degree rise in temperature would give us a climate like the south of Spain. This means there'll be palmtrees around our shores. Bougainvillea will cascade from everyone's balcony and the sky will be permanently blue. It all sounds pretty good to me, so plainly what we need are more bigger, faster cars.
quote: And the stupid thing is that you drive this thing to save the world. Look what it's done to the weather! We used to have really nice summers in England, now people are driving around in these, it's pouring with rain! Go buy a Range Rover and warm this country up again!
