New Study Shows Three Abrupt Pulses of CO2 During Last Deglaciation 132

vinces99 writes A new study shows that the increase of atmospheric carbon dioxide that contributed to the end of the last ice age more than 10,000 years ago did not occur gradually but rather was characterized by three abrupt pulses. Scientists are not sure what caused these abrupt increases, during which carbon dioxide levels rose about 10 to 15 parts per million – or about 5 percent per episode – during a span of one to two centuries. It likely was a combination of factors, they say, including ocean circulation, changing wind patterns and terrestrial processes. The finding, published Oct. 30 in the journal Nature, casts new light on the mechanisms that take the Earth in and out of ice ages.

"We used to think that naturally occurring changes in carbon dioxide took place relatively slowly over the 10,000 years it took to move out of the last ice age," said lead author Shaun Marcott, who did the work as a postdoctoral researcher at Oregon State University and is now at the University of Wisconsin-Madison. "This abrupt, centennial-scale variability of CO2 appears to be a fundamental part of the global carbon cycle."

Previous research has hinted at the possibility that spikes in atmospheric carbon dioxide may have accelerated the last deglaciation, but that hypothesis had not been resolved, the researchers say. The key to the new finding is the analysis of an ice core from the West Antarctic that provided the scientists with an unprecedented glimpse into the past."

Actually, you have to be pretty stupid to back this proposal for *at least* the following reasons:

1. Bandwidth caps: I may be charged overage fees for traffic which I didn't made
2. Legal liability: I may get sued for a infringement which I didn't made, but was made by an unknown 3rd party which I cannot identify.
3. Contract terms: AFAIK most (home) contracts forbid you to provide services to 3rd parties.
4. Service quality: I may get degraded service because of unknown 3rd parties browsing for free.

All in all, not free. Isn't it?

I have to agree with you. Here all couriers (DHL, UPS, Fedex to name a few) have what I call the "extorsion fees".

When importing a package, even if no taxes are due they charge you around $30-50 just to deliver it (remember you paid shipping before), else they will auction it.

Once I had a package with DHL which had a value of $29 (honestly!), no taxes where due (no taxes for less than $100 FOB), yet they wanted to charge me $40 for "Operating expenses". After I complained they discovered they made a "mistake" and delivered it. Even then, they failed to deliver it at the scheduled time (never got a call from them, had to wait at my house for nothing!!), but got the package the next day without any warning or even apologies.

Fedex is a bit better. Their "operating expenses" charge is higher (usually $55), but at least they live to their word on their delivery date/time. What I don't understand is that their web page advertises their services as "customs-cleared", yet they charge customs-related fees during the import process (not counting taxes, which are obviously another thing).

I haven't really have much trouble with UPS, they where a bit cheaper and delivered well.

All of them also ask too much customs-related questions (unlike my local postal office, which make things really easy), even stupid ones.

Honestly, I prefer receiving mail via my local post office (Serpost), which means that I ask my suppliers to send via USPS (in the US), Royal Mail (in the UK), etc. All of them have better rates and really good service. I usually get packages faster (and cheaper) by Express Mail than by a courier's express service (Fedex International Priority, etc). My mailman also knows me, at what time he can find me, and where he can leave packages if I'm not there. He even calls me when I have a package!

That's why I never use couriers, they suck a lot.

LucasArts Embargoes "Clone Wars" Reviews 603

An anonymous reader writes "George Lucas CGI 'Clone Wars' movie has premiered to reviews ranging from MSNBC's 'Ugly animation and an uninspired storyline drag down the film' to AintItCool's 'I hated the film. HATED IT. REALLY HATED IT.' Critics have noted the animation style, music and slapstick humor had more than a passing similarity to Pixar's Toy Story, and wondered if the introduction of new action figures (sorry, characters) like Baby Jabba Hutt and Jabba the Hutt's Gay Uncle may have taken the franchise a bridge too far. Lucas responding by enforcing an embargo, forcing the reviews to be taken down. While sites like AintItCool.com responded, by then it was just a little too late. Still, the CGI eye candy will make it popular with kids. If the 'Clone Wars' movie can't save the galaxy, can it at least save the franchise?"
