Global Warming May Cause Alien Invasion — Updated

Are these the scientists Jon Huntsman listens to? They are from NASA, so, it must be true!*

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.

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”.

Well, to make some lemonade from these lemons: As Paul Krugman argues, an alien invasion is just what we need to get our economy going again.

*A reader alerts me to this note from the author of the study explaining his relationship with NASA:

So here’s the thing. This isn’t a “NASA report.” It’s not work funded by NASA, nor is it work supported by NASA in other ways. It was just a fun paper written by a few friends, one of whom happens to have a NASA affiliation.

A while ago, a couple good friends of mine (Seth Baum and Jacob Haqq-Misra) approached me about a paper they were writing, and asked if I wanted to join them on it. The paper was a review of all the different proposed situations for contact with an alien civilization. I didn’t think this was particularly important. After all, I consider the likelihood of contact with an alien civilization to be low. It certainly wasn’t urgent, as I don’t expect this to happen anytime soon. But… it sounded like fun and I decided to join in on it. So we wrote the paper, but I have to admit that Seth and Jacob put in the vast majority of the work on it. One of the scenarios we considered in the review was the possibility that an alien civilization would contact us because they were concerned about the exponential growth of our civilization, as evidenced by climate change. This isn’t an entirely new idea; remember, this was a review effort. Indeed, Keanu Reaves recently played a similar alien in the movie “The Day the Earth Stood Still.” There were lots of other ideas we reviewed, but this was probably the most provocative.

Well, the paper came out a couple months ago. Today, for some reason, The Guardian picked it up, publishing an article about it with the following title: “Aliens may destroy humanity to protect other civilisations, say scientist: Rising greenhouse emissions may tip off aliens that we are a rapidly expanding threat, warns a report for NASA.”

That then was picked up by The Drudge Report, with this headline:

“NASA REPORT: Aliens may destroy humanity to protect other civilizations…”

UH OH. Now that is a bit problematic.

So here’s the deal, folks. Yes, I work at NASA. It’s also true that I work at NASA Headquarters. But I am not a civil servant… just a lowly postdoc. More importantly, this paper has nothing to do with my work there. I wasn’t funded for it, nor did I spend any of my time at work or any resources provided to me by NASA to participate in this effort. There are at least a hundred more important and urgent things to be done on any given work day than speculate on the different scenarios for contact with alien civilizations… However, in my free time (what precious little I have), I didn’t mind working on stuff like this every once in a while. Why? Well, because I’m a geek and stuff like this is fun to think about. Unfortunately, there is not enough time for fun. Indeed, I felt guilty at times because this has led to a lack of effort on my part in my interactions with Seth and Jacob. Beyond adding some comments here or there, I did very little for the paper.

But I do admit to making a horrible mistake. It was an honest one, and a naive one… but it was a mistake nonetheless. I should not have listed my affiliation as “NASA Headquarters.” I did so because that is my current academic affiliation. But when I did so I did not realize the full implications that has. I’m deeply sorry for that, but it was a mistake born our of carelessness and inexperience and nothing more. I will do what I can to rectify this, including distributing this post to the Guardian, Drudge, and NASA Watch. Please help me spread this post to the other places you may see the article inaccurately attributed to NASA.

One last thing: I stand by the analysis in the paper. Is such a scenario likely? I don’t think so. But it’s one of a myriad of possible (albeit unlikely) scenarios, and the point of the paper was to review them. But remember – and this is key – it’s me standing for the paper… not the full weight of the National Aeronautics and Space Administration. For anything I have done to mis-convey that to those covering this story, to the public, or to the fine employees of NASA, I apologize.

UPDATE/ADDENDUM: If anyone has further questions about the paper itself, I direct you to contact my good friend and colleague, Seth Baum. Seth is the first and corresponding author on the manuscript, so all queries should first be directed to him.
