Yes, we've reported aliens crashing down and meteorites hitting the oceans and drowning us all and whatever else.
THIS TIME, though, it's actually quite serious. Sort of.
Science-types at Stanford University - which is not one of those 'e-University' places, we think - have determined that Earth's sixth extinction event has been triggered.
Which, in layman's terms, means we're all basically shagged.
Professor Paul Ehrlich gave a very cheery summary of where we are and what's happening in the world.
"Without any significant doubt … we are now entering the sixth great mass extinction event. There are examples of species all over the world that are essentially the walking dead. We are sawing off the limb that we are sitting on."
Earth has, so far, experienced five mass extinction events. The previous one happened 65 million years ago and wiped out the dinosaurs - although if that documentary we saw, Jurassic World, is to be believed, they might be making a comeback.
Professor Ehrlich isn't the only one who's pretty sure we're all screwed.
Science Advances has said that "our analysis emphasises that our global society has started to destroy species of other organisms at an accelerating rate, initiating a mass extinction episode unparalleled for 65 million years."
So, if there's that thing you've always wanted to do, but put off because reasons? Now's the time.
We're off to find Anne Doyle and see if she fancies going scuba-diving drunk with us.
