Aliens may destroy humanity to protect other civilisations, say scientists

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

---

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 scientists at Nasa and 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.

Something else to blame on AGW; earth destroyed by aliens!

[dfwgator]

They can start in Washington DC.

[ApplegateRanch]

“Scientists” strike again with more AGW doom.

[Twotone]

They are REALLY getting desperate!!! And the more ridiculous stuff they come up with, the more they convince rational people that they are full of hot air.

It won’t be long before Al Gore and Obama warn of the same thing.

“We’ll make great pets...”

[Nachum]

So is Obama a lizard alien, or is he more of a bug type?

They would most likely be conservative. They havent visited us since we obviously havent purged all the rabid liberals from the planet.

[Repeal The 17th]

Not if we kill them first!

[John Valentine]

Another absurdity from the ridiculous and contemptible Guardian. What a complete crock.

[AlexW]

It is quite obvious.
We have them living in the White House.

When did the media admit there are aliens?

I guess the radio waves, city lights, and the occasional nuclear explosions aren’t a sufficient tip that we are here.

“Watching from afar....”

Watching from not so far away, I’d guess that NASA and Penn State had wasted a bunch of the taxpayer’s money.

Surely no REAL scientist claims this. This sounds like a scary tall tale your parent might tell you to get you to stay out of the woods. You know, “If you go into the boogie man will get you!” Sheesh.

[sand88]

is this article from April 1st? It’s beyond laughable.

“We’ll make great pets...”

Only if neutered and declawed.
