First, it was NY Times columnist Paul Krugman suggesting that a "Wag The Dog" program faking an imminent invasion by aliens (from outer space, not Juarez, Tijuana or Toronto) would help resolve political infighting and allow President Obama to steer a few more of his economic programs into law through an otherwise divided Congress.
Now, NASA --its own funding either imperiled or already cut, and looking for something, anything to work on these days-- has jumped on this bandwagon with a newly released report... raising the alarm that those ever-observant aliens scouting our planet (and occasionally anal-probing hillbillies and the mentally unstable among us) may notice ... our global warming "crisis".
And, of course, launch a preemptive attack.
Sometimes, a writer just couldn't make this kind of stuff up. Unless he works for a government agency, that is...

Aliens may destroy humanity to protect other civilizations, say NASA scientists
Rising greenhouse emissions could tip off aliens that we are a rapidly expanding threat, warns a report

When they see what a mess we've made of our planet, extraterrestrials may be forced to take drastic action.
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.
Watching from afar, extraterrestrial beings might view changes in Earth's atmosphere as symptomatic of a civilisation growing out of control – and take drastic action to keep us from becoming a more serious threat, the researchers explain.
This highly speculative scenario is one of several described by a NASA-affiliated scientist and colleagues at Pennsylvania State University that, while considered unlikely, they say could play out were humans and alien life to make contact at some point in the future.
Shawn Domagal-Goldman of NASA's Planetary Science Division and his colleagues compiled a list of plausible outcomes that could unfold in the aftermath of a close encounter, to help humanity "prepare for actual contact".
In their report, Would Contact with Extraterrestrials Benefit or Harm Humanity? A Scenario Analysis, the researchers divide alien contacts into three broad categories: beneficial, neutral or harmful.
Beneficial encounters ranged from the mere detection of extraterrestrial intelligence (ETI), for example through the interception of alien broadcasts, to contact with cooperative organisms that help us advance our knowledge and solve global problems such as hunger, poverty and disease.
Another beneficial outcome the authors entertain sees humanity triumph over a more powerful alien aggressor, or even being saved by a second group of ETs. "In these scenarios, humanity benefits not only from the major moral victory of having defeated a daunting rival, but also from the opportunity to reverse-engineer ETI technology," the authors write.
Other kinds of close encounter may be less rewarding and leave much of human society feeling indifferent towards alien life. The extraterrestrials may be too different from us to communicate with usefully. They might invite humanity to join the "Galactic Club" only for the entry requirements to be too bureaucratic and tedious for humans to bother with. They could even become a nuisance, like the stranded, prawn-like creatures that are kept in a refugee camp in the 2009 South African movie, District 9, the report explains.
The most unappealing outcomes would arise if extraterrestrials caused harm to humanity, even if by accident. While aliens may arrive to eat, enslave or attack us, the report adds that people might also suffer from being physically crushed or by contracting diseases carried by the visitors. In especially unfortunate incidents, humanity could be wiped out when a more advanced civilisation accidentally unleashes an unfriendly artificial intelligence, or performs a catastrophic physics experiment that renders a portion of the galaxy uninhabitable.
To bolster humanity's chances of survival, the researchers call for caution in sending signals into space, and in particular warn against broadcasting information about our biological make-up, which could be used to manufacture weapons that target humans. Instead, any contact with ETs should be limited to mathematical discourse "until we have a better idea of the type of ETI we are dealing with."
