Shawn Domagal-Goldman, a NASA affiliated scientist, joined with colleagues at Pennsylvania State University to complete a study that warns of possible dire consequences from extra extraterrestrials if they sense how we are destroying the planet. I kid you not; it’s in the report.

Humanity may just now be entering the period in which its rapid civilisational expansion could be detected by an ETI [Extra Territorial Intelligence] 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.
Are there any sane scientists left or have they all gone Gore?
