After the video, I suggest reading the posting by Allahpundit at HotAir.

It may not rank as the most compelling reason to curb greenhouse gases, but reducing our emissions might just save humanity from a pre-emptive alien attack, scientists claim…

The authors warn that extraterrestrials may be wary of civilisations that expand very rapidly, as these may be prone to destroy other life as they grow, just as humans have pushed species to extinction on Earth. In the most extreme scenario, aliens might choose to destroy humanity to protect other civilisations.

“A preemptive strike would be particularly likely in the early phases of our expansion because a civilisation may become increasingly difficult to destroy as it continues to expand. Humanity may just now be entering the period in which its rapid civilisational expansion could be detected by an ETI because our expansion is changing the composition of the Earth’s atmosphere, via greenhouse gas emissions,” the report states.

“Green” aliens might object to the environmental damage humans have caused on Earth and wipe us out to save the planet. “These scenarios give us reason to limit our growth and reduce our impact on global ecosystems. It would be particularly important for us to limit our emissions of greenhouse gases, since atmospheric composition can be observed from other planets,” the authors write.

As noted by the author in his posting, this silliness was not authored by Nasa, but by a Nasa affiliated, “scientist.”  So, this is what the global warming side is left with now.  Space aliens are coming to kill us because I did not buy a Chevy Volt.  Is this theme going to be played out in the upcoming Presidential election?  I hope so.  I can’t wait for Barack Obama to run ads showing Space Aliens upset with Steel Plants in America sitting idle, because they might one day again be used to create Sulfur Dioxide, and of course that useless bye product, steel.  Will we see commercials with an alien shedding a single tear down his cheek as someone drives a Hummer to work in a coal burning electric power plant?

I guess for me, what gets me most about this kind of crap is that it actually finds traction as serious argumentation.  It is hard to hold a national debate with someone who posits this type of idiocy in a serious manner.  About a decade ago, when watching court T.V., the people pontificating about the O.J. trial floated as a joke that Judge Ito might as well allow the space aliens did this defense.  It is somewhat disconcerting to me to know that this is no longer considered a joke, but a serious argument.  This is indeed a great day for America my friends.

In the spirit of liberal debate tactics, here is a list of 5 questions, just as valid about our impending alien invasion.

1)  What if the aliens are coming here to buy our muscle cars, like Corvettes, and Mustangs?
2)  What if the aliens in fact breathe Carbon Dioxide and view our efforts to limit this gas in our atmosphere as a rude gesture?
3)  Does the fact that the aliens are coming to kill us over green house gasses mean that they were O.K. with nuclear detonation?
4)  If the aliens had the technology to travel here from their own planet, and they considered Carbon Dioxide to be worthy of destroying us over, why don’t they just sell us their planet sized atmospheric Carbon Dioxide air scrubbers, (Lithium Hydroxide), which we ourselves invented for use on the various space craft we have sent to the moon and lower Earth orbit?
5) If they are coming to kill us for this, why be so shy about it for the century or so we’ve had an industrial capability?  Why not show up when the very first internal combustion engine was fired up and warn us of the galactic no-no?

The truly scary part for me is this.  About half of our country agrees with these imbeciles.
