Think isotopes.

LuckyStrike, you have been here long enough to know not to either skip the censor or post what you did outright. Don't do it again.

very interesting read, Gabriel..........followed a few of the links, and look at the time.

well, that's a sobering thought. I'll admit, I was one of the people who felt like the amount of co2 absorbed by forestry was a constant.

Gonna have to do some research on that one.......thanks, SJ..........

Looks like science just isn't for you.
You asked and I took the time to give you a proper reply.
I really don't care one way or another about your supposed sensitivities.....you don't agree with the link to H2O isotopes-------------->post a reasonable rebuttal ....this isn't the GW thread that Lan crapped up.

Here's a link to equipment so that even you could run your own unlikely experiments ( )

An interesting article by way of the Department of Energy ....on the effects of high altitude/high speed aircraft.

http://www.osti.gov/bridge/servlets/...ble/257417.pdf

According to the article, CO2 output is not an issue....the concern was H2O and effects on the ozone layer. And it reads as minimal.

Quote:
Since the radiative forcing calculated in this paper, assuming no
stratospheric temperature readjustment due to the HSCT perturbation, was not significant in
terms of large scale climate change, then the values that would result if stratospheric
temperature readjustment were allowed would also not produce significant climate changes.

From what I glanced the study pertains to HSCT planes (high speed civil transport) and not to conventional aircraft but in this context it is interesting that the kerosene comsumption of an Airbus 320 is 70 pct down compared to that of a Caravelle of 40 years ago.

sorry, link is in German from the EU. Couldn't find the English version in a hurry.

Computer industry
World wide IT emissions of CO2 correspond to those generated by air traffic.http://www.independent.co.uk/environ...es-452531.html


Google
Quote:
.........."performing two Google searches from a desktop computer can generate about the same amount of carbon dioxide as boiling a kettle" or about 7g of CO2 per search.............this does not refer to a one-hit Google search taking less than a second, which Google says produces about 0.2g of CO2, a figure we accept.............we were referring to a Google search that may involve several attempts to find the object being sought and that may last for several minutes. Various experts put forward carbon emission estimates for such a search of 1g-10g depending on the time involved and the equipment used
http://technology.timesonline.co.uk/...cle5489134.ece
The longer searches must be done by LAN in a rebuttal frenzy, thus polluting the world all on his own. We need to find the location of that cave in Arkansaw and send a drone.

Right, back to my bookshelf (now where've all those volumes of the excyclopedia gone? )

It's easy to get a translation by dropping the German URL into a Google translation service.

Thanks. I'd actually done that before with a Russian text and
shuddered at the result for a week. But in this case I was simply in a hurry.

I need to replace some outside taps which have frozen overnight and busted and I just come in from time to time to see if my fingers are still working.

Also I read German so I'm allright, so ...........

South of Spain, land of sun and mild winters. Let's hope LAN doesn't see this or we'll get another sermon on the coming ice age.

It's been a while since I tried to translate Italian, but as I remember, it didn't do well either in Google.

Speaking of hydrogen bonds/water moleclues and frozen water....if frozen water is less dense than unfrozen water, why does it break pipes? Is it because it is trying to be fluid, and still vibrating while held in suspension that it expands? What am I missing?

It's the only non metallic solid that has a lattice structure that's greater in volume than it's liquid version.
Because water expands as it freezes, it's less dense as a solid and floats in it's liquid version

Interesting article here:

I actually left mine running at a trickle, so shoudl be okay. The front one still froze, but I'm working on it now.

Interesting article abut the airbus........I remember readind some place that during the days post 9/11, there was less cloud cover over some of the bigger cities, but I just dismissed that as so much hokum pokum......now I gotta go see if I kind find the source again...........
