Activists compare climate change to alien attack: Former Calif Gov. Jerry Brown: ‘This is almost like we’re suffering an attack from Mars’ & MSNBC’s Joy Reid: If ‘aliens…come & attack us, it’s going to be because we destroyed the planet’

NBC reporter Jacob Ward: “You look at it, and you think this should be our great unifying moment, right?” Ward rhetorically asked. “This is the moment when space aliens land with ray guns and are threatening all of us and we all band together like you see in the movies. This is it. And yet, that’s not somehow happening.”

Even Ruhle halted that analogy calling it “not fair” and reminding him that “space aliens” aren’t coming for anyone.“It’s not,” she interjected. “For your average American at home, there are not space aliens coming out and saying, ‘We’re going to take you over.’”

‘So why don’t we see advanced civilisations swarming across the universe? One problem may be climate change. It is not that advanced civilisations always destroy themselves by over-heating their biospheres (although that is a possibility). Instead, because stars become brighter as they age, most planets with an initially life-friendly climate will become uninhabitably hot long before intelligent life emerges.’

‘Humanity may just now be entering the period in which its rapid civilizational expansion could be detected by an ETI because our expansion is changing the composition of Earth’s atmosphere (e.g. via greenhouse gas emissions), which therefore changes the spectral signature of Earth,” the study says’ — Update here.
