Material Used in LCD 17,000-times More Warming-Effective Than CO2
A lot of us switched over to LCD displays over CRT for reasons such as reduced electricity bills, thereby reducing our carbon-footprint. It is true, LCD displays have done a great job reducing power consumptions and effectively reducing CO2, but to what extant is this 'carbon-footprint reduction' helping reduce green-house gases?
New studies find that a material used in the manufacture of LCD displays called Nitrogen trifluoride (NF3), is the 'missing gas' which adds up to the equation of exactly which substances contribute to global-warming. A study conducted by Michael Prather (read here) reveals that this gas has a stunning 17,000 times greater contribution to global-warming. This compound is still used in the manufacturing of LCD and 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 and its nature wasn't established.
The Kyoto Protocol missed several such compounds because they felt they were used in very insignificant quantities, although at that time the harmful effects of NF3 might not have been established since Parther's letter is dated 26th June. 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 worth. The rise of digital and high-definition television resulting in increased production of LCD and related technologies in the consumer electronics industry, contributes to the rise of emission of this substance.
Environmentalists will have a tough time convincing governments to enforce regulations. The demand for LCD products is so huge, industrialists will find it too big an expense to halt production and make core redesigns to a 'hot'-selling technology.

Off-topic for a moment.. Has anyone heard that scientists have found out that if you feed this insect certain foods it excretes usable petroleum? They're working on getting that going. (More of an economy related issue) Oh I'm sorry. I didn't know the US Senate Committee was just another online newspaper.
OK. Ignore the 1 link that isn't government-involved. Just because it's a blog completely throws away any credibility of the article I guess.
Edit: I'm going to bed now. I'll wake up and reply in the morning.
I haven't heard about that insect you speak of, I'd certainly like to though, definitely link some info on that. And the middle-easter and arabian countries are claiming the skyrocketing prices are not b/c they are not selling enough, but b/c of the failing US dollar and economic situations here. I don't trust that explanation or our own gov't's completely, but what can you do?
Oh yes. I heard. Your droughts in the US are a couple of days without rain.
Our droughts = weeks - months of no rain and scorching hot and dry conditions. The drought preceeding the current one, there was only what one month between them!
Since you guys arent on the recieving end you guys don't care. Its you guys in the US who usually deny or downplay the significance of global warming. People from the rest of the world, the UK, Australia, new zealand, etcetera, ALL realise it.
I'm not anti US, i like the food (maccas ftw), i like the culture, i like the stuff that comes out of it. I just don't like how the government makes you guys think.
Your arguments that tax etc, is for greed is invalid. Its saying "Global warming doesnt exist because there is money".
And you aren't feeling the difference that .5C has given you. .5C is not enough to cause droughts. Your droughts are naturally occurring, and have nothing to do with "global warming".
And if global warming does exist, explain to me how this past year the average went down a degree, completely negating the .5C anyway.
If global warming does exist, it has nothing to do with man. It's cyclical.
Those CFL/energy saving light bulbs have their good and bad points. Good that they might save you money on your electricity bill on the long run, bad that they contain Mercury and take ages to fully light up. If you break the CFL light bulb in your house you have to open the windows and doors and leave your house for a few hours to let the mercury out... out to the environment!!
The normal light bulbs are fine, if everyone was to change over from the normal lightbulbs to the CFL ones, their would be more waste from the changeover than a full landfill dump site!!!
Another thing that really gets up my nose is those "Green" cars... like the Toyota Prius..... the batteries that are in those cars use more chemicals and CO2 to make one of them than what the average "non-green" car outputs in one year.
Yes i believe in conserving our natural resources, but if all of those tree hugging "save our planet al gores types" want to really save it... then stop breathing!!! (We exhale CO2)
Heres an interesting concept to offput CO2... seen that everyone is on the bandwagon of it..... plant more trees...or.... stop the deforestation of the amazon.... Plants and trees need CO2 to survive... they take it in and convert it to oxegen... basic chemistry! cant remember but its something like 3-4 football fields are being cut down a day in the amazon.
Al Gore really annoys me..... jetting all over the planet telling us to stop polluting the planet... then he can jet back to his nice house with his electricity bill being paid for by the average joe...... also greenpeace can go fcuk themselves.... another waste of space orgainsation... best thing the French ever did was to sink that rust bucket that greenpeace was using to motor around the planet and tell us to stop polluting.
Anyone remember those concerts held last year (think it was last year, might be the year before) with all the rock stars bragging on about conserving energy and stop polluting and cut down CO2..... little hypocritical of them... flying all over the planet to a concert that using a MASSIVE amount of electricity... hmmm.... kettle.... pot.....black?????
.5C can cause some effects.... .5 in a CPU temp can cause effects.... but nothing drastic!!

The reason i searched for these 2 words in particular is because i've seen, in documentaries, how much have certain glaciers retreated in recent years. Unfortunately, i was unable to find the glacier pics i had seen in the documentary :(
0.5º doesn't seem like much but, when compared to the changes in the other time frames (see the charts in the link), you'll get an idea why it IS significant.
The Earth has had Ice Ages for millions of years: what it didn't have until recently (100 years or so), was a 3rd party factor (Man) helping in the global temperature increase.
The politicians (worldwide) are more interested in keeping their asses in power to look @ the middle / long term effects of what they are doing.
Anyone here know their chemistry? i rememeber a lab experiement that was done in my chem lab when i was in secondary school (10 yrs ago).... CO2 is a heavy gas... how can i get up to the atmosphere?? Has CO2 lost weight?? Been to the gym??
It seems that if a scientist wasnt to get tonnes of funding or want their name on the latest edition of Scientist Weekly they just say that the study they want want to do, are doing or just finsished is related to climate change! BAM... instant funding....!!!!!!!!!!!!!! Cant beleive all our our tax dollars are going towards something we have literally no power over.... no control over.... and not our doing!!

Even considering this a problem is like being concered that the sun is gonna go Nova or the Universe emplode one day. I don't waste my time considering what is going to happen i have better things to do. The only thing affected by this is guess what, life on the planet, which if life is here after the last ice age and if man survived the last iceage and we wore fur, don't you think even today we are equipped to handle it, heck think of all the fresh water we will have to drink and all the frozen fish, we won't even have to pay for plumbing and who needs to worry about food with millions of prefrozen uncooked fish, heck the next iceage is like the frozen meat section at the store. And well let it come, i got a blanket, and i got a heater, and i still have my Y2K stock of toliet paper
ANyway, this is my last post on the subject. You all know my stance. Provide me with hard evidence, and I'll change my views. But until then, it's all just speculation.
All i can say is clothing stores will sell less coats and more swim trunks, bout damn time to, its to cold in the winter for a proper BBQ
EDIT Ofc it's natural: what's unnatural, as the pic clearly shows, is the time frame in which the increase took place.
As for Office, im not a politcian, i hate them, every last one of them, i just vote for the republican one because i hate them slighly less
Hi friends i am very interested to join you.global warming is mainly caused by man activities.so we must aware of the problem created by people.so, we must ready to bothering others also.

From Wikipedia: Do you know what the overall decrease in temperature (globally) was?
According to this, it was ~3º: ~3º and it caused a year without summer.
For a few more years after 1815, the temperatures recorded were abnormally low.
OK: this was a 1 time event but i'm only using it to show what a mere 3º difference in global temperature can do.
We're seeing a 0.5 increase over the last 100 years or so and, although it seems insignificant to many, it most certainly is NOT.
