Study: Global warming could lead to alien attack to save galaxy

By Andrew Moran     Aug 22, 2011 in Science
Pittsburgh - An out-of-this-world, joint study between researchers affiliated with NASA's Planetary Science Division and Penn State University suggests that global warming could trigger an alien attack against humanity in order to save the Milky Way Galaxy.
As the theory of Anthropogenic Global Warming persists and more disastrous updates pour in as to the damage that could occur due to global warming, one study is suggesting a more intergalactic hypothesis.
According to a new 36-page paper by researchers with NASA and Pennsylvania State University called “Would contact with extraterrestrials benefit or harm humanity? A scenario analysis,” humanity could be wiped out by an extraterrestrial species for the greater good of the Milky Way Galaxy.
Due to mankind’s polluting behavior and the proposed man-made global warming, aliens would fear that the human race could expand its civilization and become destructive to the rest of the galaxy.
“A preemptive strike would be particularly likely in the early phases of our expansion because a civilization may become increasingly difficult to destroy as it continues to expand,” the study’s lead author, Domagal Goldman, suggests.

“Humanity may just now be entering the period in which its rapid civilizational expansion could be detected by an ETI (extraterrestrial intelligence) because our expansion is changing the composition of the Earth's atmosphere, via greenhouse gas emissions.”
How would aliens kill us off? The most deadly scenario suggests that aliens could use a variety of weapons, such as enslaving us, attacking us, eating us or even spreading an alien disease among the population or food species.
However, not all scenarios put forward end with humanity becoming exterminated.
Another suggested scenario includes aliens making contact with us and providing the world with advanced technology and better knowledge to deal with the world’s leading issues of poverty, hunger and deadly diseases.
Intelligent extraterrestrials would detect changes in our planet’s atmosphere by utilizing spectrometry – a tool used to divide and recognize ions in a gas phase.
The authors of the study confirmed that the study was not a NASA report nor did they receive any funding from NASA, notes the International Business Times.
