What If It's the Other Way Around?

According to the Guardian, someone with too much free time at NASA has been warning us that aliens might be ready to DESTROY OUR PLANET if we don't stop emitting greenhouse gases:

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.

Even if we assume that these ETs just happen to have the same environmentalist ethical standards that we have acquired in the past 1/100 of 1% of human existence, they might regard greenhouse emitters as a rare ecological niche that must be preserved. The usual type of wildlife can be observed anywhere but this might be the only place in the Galaxy where soft coal or plutonium are used outside museums.

They might get really p---ed off if we stop.
