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.
In 2006, while flying by Saturn’s moon Titan, the radar on NASA’s Cassini orbiter discovered seas of liquid ethane and methane on the moon’s –300ºF surface, the only bodies of liquid we know of that exist anywhere but on Earth. Some of the oily seas appeared on Cassini’s radar to be larger than Lake Superior, but visibility was poor because Titan’s atmosphere is thick and hazy.
