Now that Americans are becoming increasingly skeptical of the anthropogenic global warming theory, climate scientists have been forced to get even more creative with their climate change alarmism.

Here’s the latest fanatical claim, via a NASA/Penn State scientific study: A band of moralistic, environmental-loving aliens may attack and destroy humanity (for the greater good of the universe, of course!), unless we can get our carbon emissions under control.

Yes, this was written in a taxpayer-funded study. The Guardian reports:

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…

The authors warn that extraterrestrials may be wary of civilisations that expand very rapidly, as these may be prone to destroy other life as they grow, just as humans have pushed species to extinction on Earth. In the most extreme scenario, aliens might choose to destroy humanity to protect other civilisations.

“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.

As long as we’re using the threat of alien invasions to advance our own personal whims and agendas, this study seems like a perfect argument for giant killer space lasers.
