LCD TVs, praised as being greener than the CRT because they
consume much less power, may actually be
speeding climate change due to the use of NF3.
NF3 is 17,200 times better at trapping heat in the
atmosphere over a hundred-year period than is carbon dioxide. The
problem is, NF3 emission levels aren't being
measured by the worldwide greenhouse-gas monitoring programme put
in place by the Kyoto Protocol on climate change. There's no
word in the article about what sort of nasty vapors and toxins
are emitted in manufacturing of a CRT set.
As in the increased cow flatulence due to the heavy beef diet of
many nations? What about sheep flatulence because of the
population's demand for wool?
That's not fair. No one said anything about "Gaia's
grand plan" or "living in harmony with nature".
Straw man.
Also, I'm pretty sure your hypothesis is wrong. If you have
any evidence at all that human agriculture has been staving off
an ice age, the world would surely love to see it.
turkeys keep the planet warm, the year to year increase in turkey
flocks is creating global warming. For proof, look no
further than Thanksgiving holiday, we eat most the turkeys and
then winter comes. With the birth of poults comes spring
and then summer as they grow into big gobblers.
I mention the Assessment of Ozone Depletion because it looks like
it is a substitute for an ozone-layer harming gas. Also,
according to the Air Liquide Encyclopedia, it's
heavier-than-air.
The latest issue is not yet up at the AGU website (American
Geophysical Union).
Climate change and greenhouse gas emissions are real problems. I
get the feeling that this story (the Reg's take, not the
paper) is meant to make us "greens" look stupid, and to
convince everyone else that it's pointless to worry about
co2.
I will reserve judgment on the paper until I can read the
abstract, but I am almost totally sure that the author is not
suggesting that co2 emissions aren't a problem.
If nitrogen trifluoride is 17,200 times better at trapping heat,
but if there's (for example) a million times less of it than
there is of CO2, then it would be lost in the noise. We need to
know how much less of it there is.
The linked article is completely silent about the numbers that
are indispensable for having an informative story. Going over to
look at Geophysical Research Letters, the abstract says that
estimated 2008 production of nitrogen trifluoride (not releases,
production: it's toxic and may be controlled already) is
"equivalent to 67 million metric tons of CO2". Compare
that to our annual manmade emissions of 26 billion tons of CO2.
Another number appears in the sentence "If released, annual
production would increase the lower atmospheric abundance by 0.4
ppt". Carbon dioxide is measured in hundreds of parts per
million. Nitrogen trifluoride is measured in tenths of a part per
trillion.
Could you post a link to that abstract? I could not find it, and
I said above, apparently in error, that it's not on the AGU
site yet... My second episode of stupidity in so many comments on
this story.
A quick Google suggests that NF3 production facilities produce a
few hundred tonnes a year, global production is a few thousand or
tens of thousands of tonnes a year, so 10's or 100's of
millions of tonnes CO2 equivalent (yawn).
Probably enough to dent the green credentials of anything
produced with it, but small fry as regards global warming.
Some users of NF3 ensure it is combusted before atmospheric
release, because it is toxic, so the exact figure will depend on
precisely how it is used.
I like The Register and have been reading it daily for the past
decade or so, not to mention the competing blog The Inquirer
founded by the former owner of The Reg. However, in recent
months, it has been devoting a lot of space to silly articles by
global-warming skeptics and others opposed to "green"
initiatives. Today there was a feature about how wind power
wouldn't be useful for the UK, because there are periods when
there's no wind anywhere in the UK or nearby Europe (due to
big high pressure systems). That was fairly rational,
though it tries to lead one to conclude that green power is a bad
idea.
The consequences of global warming, not to mention depletion of
some fuel supplies, are serious and even depressing. When
faced with a bad situation, one option is denial. Simply
pretend it ain't so! A second approach, more popular in
the US than Europe, is to adopt a religion that believes that the
world is coming to an end soon anyway, so we may as well party
like it's 1999. These are both irrational but
understandable variations on a theme. A third approach is
despair; don't do anything and disparage those who try.
A fourth is to become an activist to try to fix things. The
Reg leans towards the first and third options.
Technocrat has more people in the fourth category.
Well put. The article (the Reg's) is from the viewpoint of
the third option.
Not sure about your speculation about technocrats, though. Seems
like many have a libertarian-leaning-towards-survivalism streak.
Perhaps a fifth option: survivalist secretly wishing to test
their mettle.
Where they
used to be snarky, informative, topical, and relevant The
Register has for a while now been completely full of shit. A
while back they suddenly started randomly picking issues to be
against and disparaging random people involved or interested in
the issues. The last climate related
article from The Register we had on Technocrat was a complete
unethical farce. Starting with a
letter in Nature Magazine, they took a title and a few choice
phrases of the abstract and then dredged around and found a
newspaper’s website for unrelated climate sounding text and
some climate obstructionist kook website for some graphs and
mashed them together. Having read the
letter in Nature, it was clear that they only used name
“Nature Magazine” to falsify some sort of credibility
where the article clearly had none.
What’s so
disappointing is how many news aggregation / Weblog sites were
completely uncritical with their coverage of it (Technocrat
included).
As an
American citizen the American public’s reaction to
environmental, energy & other resource supply, and health
care issues has long been a source of frustration to
me. However the reaction to warnings
of climate change during the Bush Administration exceeds all of
my most cynical imaginings. The
successful binding of these issues to imagined leftwing, Marxist,
American-Hating, liberals is going to have far reaching
consequences. Today the news is
dominated consequences of the politicizing of science and the
glorification of extremist consumer culture and few, if any,
people understand that. I wonder how
bad it will have to get before most Americans come to the
understanding that these issues are importance to all people and
that ignoring the problems and going shopping in their giant SUV
is hurting themselves just as much as it is hurting everyone
else.
Is the LCD greener than the CRT?
