Aliens! Aliens Everywhere!

This today from The Guardian:

Aliens may destroy humanity to protect other civilisations, say scientists

Rising greenhouse emissions could tip off aliens that we are a rapidly expanding threat, warns a report 

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. 

"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.

Granted, this is just one of many scenarios that were thought up by NASA affiliated scientists from Penn State University (the same university of the (in)famous Michael Mann, AGW alarmist du jour).

But lest we forget that infamous Paul Krugman rant about needing inflation to stimulate the economy (seriously, how did he win a Nobel). His solution? Why faking a hostile alien invasion, of course.

Video of evidence of a Krugman WTF:

Yep, that's Krugman, Nobel Laureate, saying the US government should fake an alien invasion to "stimulate" the economy.

So we've got on one hand Paul Krugman, heralded economic genius of the mainstream, saying the US should fake an alien invasion, and we have scientists from Penn St, most assuredly working under heralded climatology genius of the mainstream Michael Mann, saying aliens may destroy the human race because of how we've treated the climate.

Now, you can take this with a grain of salt, probably should really) but don't be surprised when in a few years we get the announcement: ZOMG ALIENS R GOIN 2 KEEL US!!!11!1!11!!
